弹出框

背景

鉴于Android提供的默认弹出框很一般，IOS的弹出框样式还不错，同时使用弹出框dialog的需求还是蛮高的，于是就想仿照ios弹出框封装一个通用的dialog，解决操作询问，提示信息，列表选择等需求；同时在搜索数据的时候，需要选择条件，也是使用弹出框解决，类似于美团的顶部筛选框，今天就来封装下

提示与询问弹出框

为了解决确认、取消这种询问性的需求，还有提示性的需求，我们使用Dialog来仿一个ios式的弹出框，样式简洁大方，效果如图：

实现

主要还是自定义一个类继承Dialog，实现比较简单，如下

package com.mango.dialog;import android.app.Dialog;import android.content.Context;import android.graphics.drawable.ColorDrawable;import android.text.TextUtils;import android.view.Gravity;import android.view.View;import android.view.Window;import android.view.WindowManager;import android.widget.Button;import android.widget.LinearLayout;import android.widget.TextView;import com.mango.dialog.listener.OnOptionListener;import com.mango.dialog.utils.DisplayUtil;/*** @ClassName mango* @Description TODO(操作询问框 提示框)* @author cxy* @Date /6/27 15:19*/public class OptionAskDialog extends Dialog implements View.OnClickListener {private String TAG = "OptionAskDialog";private Context mContext;private TextView tv_title;private TextView tv_content;private Button btn_sure;private Button btn_cancle;private LinearLayout ll_title;private View line;private OnOptionListener livingSure;private String typeResult;private OptionAskDialog(Context context) {super(context);mContext = context;View view = View.inflate(context, R.layout.dialog_ask,null);setContentView(view);findViewId(view);initWindow();}private OptionAskDialog(Context context, int themeResId) {super(context, themeResId);mContext = context;View view = View.inflate(context, R.layout.dialog_ask,null);setContentView(view);findViewId(view);initWindow();initClick();}private void initClick() {btn_sure.setOnClickListener(this);btn_cancle.setOnClickListener(this);}private void findViewId(View view) {tv_title = (TextView) view.findViewById(R.id.tv_title);tv_content = (TextView) view.findViewById(R.id.tv_content);btn_sure = (Button) view.findViewById(R.id.btn_sure);btn_cancle = (Button) view.findViewById(R.id.btn_cancle);ll_title = (LinearLayout) view.findViewById(R.id.ll_title);line = view.findViewById(R.id.line);}private void initView(String title_dialog,String content_dialog,String btn_left,String btn_right) {if (!TextUtils.isEmpty(title_dialog)) {tv_title.setText(title_dialog);}if (!TextUtils.isEmpty(content_dialog)) {tv_content.setText(content_dialog);}if (!TextUtils.isEmpty(btn_left)) {btn_sure.setText(btn_left);}if (!TextUtils.isEmpty(btn_right)) {btn_cancle.setText(btn_right);}}/*** 设置dialog的背景、宽度、位置*/private void initWindow() {Window dialogWindow = getWindow();dialogWindow.setBackgroundDrawable(new ColorDrawable(0));dialogWindow.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN| WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN);WindowManager.LayoutParams lp = dialogWindow.getAttributes();lp.width = (int) (DisplayUtil.getScreenWidth(mContext) * 0.8);lp.gravity = Gravity.CENTER;dialogWindow.setAttributes(lp);}/*** 是否隐藏标题* @param isShow*/private void setTitleVisible(boolean isShow) {if (isShow) {ll_title.setVisibility(View.VISIBLE);line.setVisibility(View.VISIBLE);btn_cancle.setVisibility(View.VISIBLE);btn_sure.setText(R.string.ok);btn_sure.setBackgroundResource(R.drawable.selector_askdialog_ok);} else {ll_title.setVisibility(View.GONE);line.setVisibility(View.GONE);btn_cancle.setVisibility(View.GONE);btn_sure.setText(R.string.i_know);btn_sure.setBackgroundResource(R.drawable.selector_askdialog_fullok);}}private void initListener(OnOptionListener livingSure, String typeResult){this.livingSure = livingSure;this.typeResult = typeResult;}/*** 点击确定按钮*/public void clickSure(){if (livingSure != null) {livingSure.onOptionSure(typeResult);}dismiss();}/*** 点击取消按钮*/public void clickCancle(){if (livingSure != null) {livingSure.onOptionCancle(typeResult);}dismiss();}@Overridepublic void onClick(View v) {if (v.getId() == R.id.btn_cancle) {clickCancle();} else {clickSure();}}public static class Bulid{private Context mContext;private String title_dialog;private String content_dialog;private String btn_left;private String btn_right;private String typeResult;private OnOptionListener optionListener;private int themeResId;private boolean isShowTitle = true;public Bulid(Context context, int themeResId) {mContext = context;this.themeResId = themeResId;}public Bulid setShowTitle(boolean showTitle) {isShowTitle = showTitle;return this;}public Bulid setTitle_dialog(int title_dialog) {this.title_dialog = mContext.getResources().getString(title_dialog);return this;}public Bulid setTitle_dialog(String title_dialog) {this.title_dialog = title_dialog;return this;}public Bulid setContent_dialog(int content_dialog) {this.content_dialog = mContext.getResources().getString(content_dialog);return this;}public Bulid setContent_dialog(String content_dialog) {this.content_dialog = content_dialog;return this;}public Bulid setBtn_left(int btn_left) {this.btn_left = mContext.getResources().getString(btn_left);return this;}public Bulid setBtn_right(int btn_right) {this.btn_right = mContext.getResources().getString(btn_right);return this;}public Bulid setOptionListener(OnOptionListener optionListener, String typeResult) {this.optionListener = optionListener;this.typeResult = typeResult;return this;}public OptionAskDialog create(){OptionAskDialog ackDialog;if (themeResId == 0) {ackDialog = new OptionAskDialog(mContext);} else {ackDialog = new OptionAskDialog(mContext,themeResId);}ackDialog.initView(title_dialog,content_dialog,btn_left,btn_right);ackDialog.setTitleVisible(isShowTitle);ackDialog.initListener(optionListener,typeResult);return ackDialog;}}}

使用

public void showTitle(View v) {new OptionAskDialog.Bulid(this,R.style.Dialog).setOptionListener(this,"1").setTitle_dialog(R.string.dialog_title).setContent_dialog(R.string.dialog_content).create().show();}public void showNoTitle(View v){new OptionAskDialog.Bulid(this,R.style.Dialog).setShowTitle(false).setOptionListener(this,"2").setTitle_dialog(R.string.dialog_title).setContent_dialog(R.string.dialog_content_sure).create().show();}

列表选择框

有时候你需要向用户提供一些选项，让用户从列表中选择，如果还是像上面这种就比较丑了；可以设计成从底部弹出，如图：

实现

第一步：定义Dialog

public class OptionSheetDialog implements AdapterView.OnItemClickListener {private WeakReference<Context> mContext;private Dialog dialog;private RelativeLayout rl_content;private TextView txt_title;private TextView txt_cancel;private ListView mListview;private BaseAdapter adapter;private float scale;private OnItemClickListener onItemClickListener;public OptionSheetDialog(Context context) {this.mContext = new WeakReference<>(context);scale = DisplayUtil.getDensity(mContext.get());}public OptionSheetDialog builder() {// 获取Dialog布局View view = LayoutInflater.from(mContext.get()).inflate(R.layout.dialog_sheet, null);// 获取自定义Dialog布局中的控件rl_content = (RelativeLayout) view.findViewById(R.id.rl_content);mListview = (ListView) view.findViewById(R.id.lv);mListview.setOnItemClickListener(this);txt_title = (TextView) view.findViewById(R.id.txt_title);txt_cancel = (TextView) view.findViewById(R.id.txt_cancel);txt_cancel.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {dialog.dismiss();}});// 定义Dialog布局和参数dialog = new Dialog(mContext.get(), R.style.ActionSheetDialogStyle);dialog.setContentView(view);//设置显示坐标、位置、宽度Window dialogWindow = dialog.getWindow();dialogWindow.setGravity(Gravity.BOTTOM);WindowManager.LayoutParams lp = dialogWindow.getAttributes();lp.x = 0;lp.y = 0;lp.width = DisplayUtil.getScreenWidth(mContext.get()) - (int)(16*scale + 0.5f);dialogWindow.setAttributes(lp);return this;}}

第二步：既然有LitView，那肯定需要adapter

public OptionSheetDialog setAdapter(BaseAdapter adapter) {this.adapter = adapter;return this;}

第三步：现在需要考虑这个弹出框的高度问题了，既然是ListView，那它的item数量可能只有一个，两个…100个，所以肯定不能有多少个item，dialog就有多高，需要进行动态设置

/*** 根据item数量动态设置listview的高度* item数量在5个以下，高度由item个数决定* item数量在5个及以上，高度固定是5个item高度总和*/private void setSheetItems() {int height = (int) (LISTVIEW_ITEM_HEIGHT * scale + 0.5f);int totalHeight;RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams) mListview.getLayoutParams();if (adapter.getCount() >= MAX_ITEM_HEIGHT) {params.height = height * MAX_ITEM_HEIGHT;totalHeight = height * MAX_ITEM_HEIGHT;mListview.setLayoutParams(params);} else {params.height = height * adapter.getCount();totalHeight = height * adapter.getCount();mListview.setLayoutParams(params);}ViewGroup.LayoutParams vl = rl_content.getLayoutParams();vl.height = (int) (DIALOG_TITLE_HEIGHT * scale + 0.5f) + totalHeight + (int) (DIALOG_CANCLE_HEIGHT * scale + 0.5f);rl_content.setLayoutParams(vl);mListview.setAdapter(adapter);}

第四步：就是显示弹出框了，不过在show之前，调用下setSheetItems方法

public void show() {setSheetItems();dialog.show();}

使用

private List<SheetItem> itemList = new ArrayList<>();private List<SheetItem> moreItemList = new ArrayList<>();private SheetAdapter sheetAdapter;itemList.add(new SheetItem("清空消息列表",R.color.sheet_red));moreItemList.add(new SheetItem("发送给好友",R.color.sheet_blue));moreItemList.add(new SheetItem("转载到空间相册",R.color.sheet_blue));moreItemList.add(new SheetItem("上传到群相册",R.color.sheet_blue));moreItemList.add(new SheetItem("保存到手机",R.color.sheet_blue));moreItemList.add(new SheetItem("发送到朋友圈",R.color.sheet_blue));moreItemList.add(new SheetItem("查看聊天图片",R.color.sheet_blue));sheetAdapter = new SheetAdapter(this);public void showSheet(View v){sheetAdapter.setItemList(itemList);new OptionSheetDialog(MainActivity.this).builder().setTitle("清空消息列表后，聊天记录依然保留，确定要清空消息列表？").setCancelable(true).setCanceledOnTouchOutside(true).setAdapter(sheetAdapter).setOnItemClickListener(this).show();}public void showMoreSheet(View v){sheetAdapter.setItemList(moreItemList);new OptionSheetDialog(MainActivity.this).builder().setTitle("请选择操作").setCancelable(true).setCanceledOnTouchOutside(true).setAdapter(sheetAdapter).setOnItemClickListener(this).show();}

顶部条件筛选框

这种弹出框比较适合选择条件搜索的需求，而且是分类别的条件，比如你在美团上搜外卖，按条件搜商家；在淘宝京东上按条件搜商品等；如图：

具体实现前分析下实现思路：

首先可以确定使用PopupWindow来作为弹出框的载体，易于显示位置的确定

弹出框内容分为两部分：第一部分是条件展示，可以使用ListView来显示条件列表；第二部分是按钮操作，处于弹出框底部，用两个Button或者Textview就行了

其中第二部分很简单，主要是第一部分，条件是分类别的，然后类别下又分很多子选项，所以把类别和子选项一起作为Item；其中子选项可以是一个自定义ViewGroup，显示众多子选项

其实第一部分也可以是一个ScrollView，然后开发者可以往里动态添加自己编写的各式各样的Item，这样扩展性更强，更灵活；我这里是从通用性和简易型角度考虑选择了上面使用ListView的方案

实现

先封装 搜索条件对象，这个对象主要包括类型及包括的条件

/*** @Description TODO(搜索条件对象)* @author cxy* @Date /6/28 11:51*/public class FilterTypeBean {/*** 筛选条件所属的类型*/private String typeName;/*** 包含的条件*/private List<Condition> children;public String getTypeName() {return typeName;}public void setTypeName(String typeName) {this.typeName = typeName;}public List<Condition> getChildren() {return children;}public void setChildren(List<Condition> children) {this.children = children;}public static class Condition {//条件名称private String value;//是否选中private boolean isSelected = false;public String getValue() {return value;}public void setValue(String value) {this.value = value;}public boolean isSelected() {return isSelected;}public void setSelected(boolean selected) {isSelected = selected;}}}

接下来需要重新定义下ListView，因为它的高度决定了弹出框的高度，我给它指定高度

/*** @Description TODO()* @author cxy* @Date /6/28 10:52*/public class FixedHeightListView extends ListView {private Context mContext;public FixedHeightListView(Context context) {this(context, null);}public FixedHeightListView(Context context, AttributeSet attrs) {this(context, attrs, 0);}public FixedHeightListView(Context context, AttributeSet attrs, int defStyleAttr) {super(context, attrs, defStyleAttr);init(context);}private void init(Context context) {mContext = context;}@Overrideprotected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {try {/*** 设置ListView高度不能超过屏幕高度一半* 因为下面有按钮，所以使用屏幕一半高度减去100*/heightMeasureSpec = MeasureSpec.makeMeasureSpec(DisplayUtil.getScreenHeight(mContext) / 2 - 100, MeasureSpec.AT_MOST);} catch (Exception e) {e.printStackTrace();}//重新计算控件高、宽super.onMeasure(widthMeasureSpec, heightMeasureSpec);}}

自定义ViewGroup

到这一步就需要自定义ViewGroup了，摆放搜索条件；自定义ViewGroup主要有两件事：第一就是重写onMeasure方法测量子控件的宽高和自己的宽高，第二就是重写onLayout方法摆放子控件的位置

先重写onMeasure方法，这里需要考虑viewGroup的宽度，同时高度需要考虑使用多少行来展示子view

/*** 测量子view大小 和自己大小* @param widthMeasureSpec* @param heightMeasureSpec*/@Overrideprotected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {//从约束规范中获取尺寸int sizeWidth = MeasureSpec.getSize(widthMeasureSpec);//获取测量规格int modeWidth = MeasureSpec.getMode(widthMeasureSpec);int sizeHeight = MeasureSpec.getSize(heightMeasureSpec);int modeHeight = MeasureSpec.getMode(heightMeasureSpec);//viewgroup的宽度int width = 0;//viewgroup的高度int height = 0;//一行子view的宽度之和int lineWidth = 0;//一行子view的高int lineHeight = 0;//获取子view数量int count = getChildCount();for (int i = 0; i < count; i++) {View child = getChildAt(i);//如果子View设置了GONE属性，就跳过if (child.getVisibility() == View.GONE) {//计算viewgroup宽高if (i == count - 1) {width = Math.max(lineWidth, width);height += lineHeight;}continue;}//计算这个子view的大小measureChild(child, widthMeasureSpec, heightMeasureSpec);MarginLayoutParams lp = (MarginLayoutParams) child.getLayoutParams();//设置子view的marginlp.leftMargin = 10;lp.rightMargin = 10;lp.topMargin = 10;lp.bottomMargin = 10;//计算子view的宽高int childWidth = child.getMeasuredWidth() + lp.leftMargin + lp.rightMargin;int childHeight = child.getMeasuredHeight() + lp.topMargin + lp.bottomMargin;/*** 1.如果算出来的子view宽度和 > ViewGroup能使用的宽度值，那就说明需要重启一行显示了，就需要重新计算ViewGroup的宽高及每行的宽高* 那就取width和lineWidth最大值并赋值给width，即一行的宽度或者说ViewGroup的宽度* 新的一行的宽度lineWidth就重置为子view宽度childWidth，下一行第一个子view* ViewGroup的高度height等于与每行高度lineHeight之和* 同时新的一行的高度lineHeight重置为子view的高度** 2.如果算出来的子view宽度和 <= ViewGroup能使用的宽度值，说明这些子view可以摆在同一行* 那么一行宽度lineWidth等于子view宽度之和* 一行lineHeight取子view高度和上一行高度lineHeight最大值*/if (lineWidth + childWidth > sizeWidth - getPaddingLeft() - getPaddingRight()) {width = Math.max(width, lineWidth);lineWidth = childWidth;height += lineHeight;lineHeight = childHeight;} else {lineWidth += childWidth;lineHeight = Math.max(lineHeight, childHeight);}/*** 当最后一个子view计算完了* viewGroup的宽度取lineWidth和width最大值* viewGroup的高度取前面N行高度+最后一行高度*/if (i == count - 1) {width = Math.max(lineWidth, width);height += lineHeight;}}/*** 保存测量后的宽高* 如果指定了ViewGroup的宽高，那就用指定的宽高* 否则使用测量出来的宽高值*/setMeasuredDimension(modeWidth == MeasureSpec.EXACTLY ? sizeWidth : width + getPaddingLeft() + getPaddingRight(),modeHeight == MeasureSpec.EXACTLY ? sizeHeight : height + getPaddingTop() + getPaddingBottom());}

然后重写onLayout方法，摆放每一个子view，具体要算出每个子view的上下左右四个值，换行时要重新计算left值和top值

/*** 摆放子view的位置* @param changed* @param l* @param t* @param r* @param b*/@Overrideprotected void onLayout(boolean changed, int l, int t, int r, int b) {mAllViews.clear();mLineHeight.clear();mLineWidth.clear();lineViews.clear();//viewgroup宽度int width = getWidth();//一行宽度int lineWidth = 0;//一行高度int lineHeight = 0;//子view数量int count = getChildCount();for (int i = 0; i < count; i++) {View child = getChildAt(i);if (child.getVisibility() == View.GONE) {continue;}MarginLayoutParams lp = (MarginLayoutParams) child.getLayoutParams();int childWidth = child.getMeasuredWidth();int childHeight = child.getMeasuredHeight();/*** 如果已经计算的一行宽度+当前子view的宽度+leftMargin+rightMargin 大于 一行实际能显示的宽度* 这就需要折行显示了* 那就保存已经算出来的一行高度、宽度、这一行所包含的view* 然后重置下一行宽度为0，高度为当前子view的高度加topMargin，bottomMargin，并实例化保存新一行子view的list*/if (lineWidth + childWidth + lp.leftMargin + lp.rightMargin > width - getPaddingLeft() - getPaddingRight()) {mLineHeight.add(lineHeight);mLineWidth.add(lineWidth);mAllViews.add(lineViews);lineWidth = 0;lineHeight = childHeight + lp.topMargin + lp.bottomMargin;lineViews = new ArrayList<>();}//计算一行的宽度=前面计算的一行宽度+当前子view的宽度及leftMargin和rightMarginlineWidth += childWidth + lp.leftMargin + lp.rightMargin;//计算一行的高度取lineHeight和子view的实际高度最大值lineHeight = Math.max(lineHeight, childHeight + lp.topMargin + lp.bottomMargin);//保存子viewlineViews.add(child);}//保存每行的高度、宽度、子viewmLineHeight.add(lineHeight);mLineWidth.add(lineWidth);mAllViews.add(lineViews);int left = getPaddingLeft();int top = getPaddingTop();//viewgroup的行数int lineNum = mAllViews.size();for (int i = 0; i < lineNum; i++) {//一行的子viewlineViews = mAllViews.get(i);//这一行需要的高度lineHeight = mLineHeight.get(i);//这一行需要的宽度int currentLineWidth = mLineWidth.get(i);//每次换行重新计算left值，getPaddingLeft获取viewgroup的PaddingLeftswitch (this.mGravity) {case LEFT:left = getPaddingLeft();break;case CENTER:left = getPaddingLeft();break;case RIGHT:left = width - currentLineWidth + getPaddingLeft();break;}//遍历每行子viewfor (int j = 0; j < lineViews.size(); j++) {View child = lineViews.get(j);if (child.getVisibility() == View.GONE) {continue;}MarginLayoutParams lp = (MarginLayoutParams) child.getLayoutParams();//计算子view 的left值=当前left+子view自身的leftMarginint lc = left + lp.leftMargin;//计算子view 的top值=当前top+子view 的topMarginint tc = top + lp.topMargin;int rc = lc + child.getMeasuredWidth();int bc = tc + child.getMeasuredHeight();//摆放子viewchild.layout(lc, tc, rc, bc);//下一个子view 的left=当前left+当前子view的宽度+当前子view的leftMargin与rightMarginleft += child.getMeasuredWidth() + lp.leftMargin + lp.rightMargin;}//计算下一行的top=当前top+一行高度top += lineHeight;}}

最后重写下generateLayoutParams方法，返回布局参数类LayoutParams

@Overridepublic LayoutParams generateLayoutParams(AttributeSet attrs) {return new MarginLayoutParams(getContext(), attrs);}@Overrideprotected LayoutParams generateDefaultLayoutParams() {return new MarginLayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);}@Overrideprotected LayoutParams generateLayoutParams(LayoutParams p) {return new MarginLayoutParams(p);}

最后就是实现PopupWindow

public class MangoPopWindow extends PopupWindow {private final Activity context;private final List<FilterTypeBean> dictList;private FixedHeightListView mListView;private TextView tvReset, tvConfirm;private View nullView;private PopAdapter adapter;private OnConfirmClickListener onConfirmClickListener;public MangoPopWindow(Activity context, List<FilterTypeBean> dictList ) {this.context = context;this.dictList=dictList;initPop();}private void initPop() {View popView = View.inflate(context, R.layout.listview_popwindow, null);//设置viewthis.setContentView(popView);//设置宽高（也可设置为LinearLayout.LayoutParams.MATCH_PARENT或者LinearLayout.LayoutParams.MATCH_PARENT）this.setWidth(-1);this.setHeight(-2);//设置PopupWindow的焦点this.setFocusable(true);//设置窗口以外的地方点击可关闭this.setOutsideTouchable(true);//设置背景透明this.setBackgroundDrawable(new ColorDrawable(0x33000000));mListView = (FixedHeightListView) popView.findViewById(R.id.listview);tvReset = (TextView) popView.findViewById(R.id.tv_reset);tvConfirm = (TextView) popView.findViewById(R.id.tv_confirm);nullView = popView.findViewById(R.id.view_null);adapter = new PopAdapter(context, dictList);mListView.setAdapter(adapter);tvReset.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View view) {for (int x = 0; x < dictList.size(); x++) {List<FilterTypeBean.Condition> childrenBeen = dictList.get(x).getChildren();for (int y=0;y<childrenBeen.size();y++){if (childrenBeen.get(y).isSelected()) {childrenBeen.get(y).setSelected(false);}}}adapter.notifyDataSetChanged();}});tvConfirm.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View view) {onConfirmClickListener.onConfirmClick();dismiss();}});nullView.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View view) {dismiss();}});}public void setOnConfirmClickListener(OnConfirmClickListener onConfirmClickListener){this.onConfirmClickListener=onConfirmClickListener;}public interface OnConfirmClickListener{void onConfirmClick();}}

使用

private void initView() {ivBack = (ImageView) findViewById(R.id.iv_back);tvFilter = (TextView) findViewById(R.id.tv_flow);tvFilter.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View view) {mPopWindow = new MangoPopWindow(MainActivity.this, dictList);mPopWindow.showAsDropDown(ivBack);mPopWindow.setOnConfirmClickListener(new MangoPopWindow.OnConfirmClickListener() {@Overridepublic void onConfirmClick() {StringBuilder sb = new StringBuilder();for (FilterTypeBean fb : dictList) {List<FilterTypeBean.Condition> cdList = fb.getChildren();for (int x = 0; x < cdList.size(); x++) {FilterTypeBean.Condition children = cdList.get(x);if (children.isSelected()) {sb.append(fb.getTypeName() + ":" + children.getValue() + "；");}}}if (!TextUtils.isEmpty(sb.toString())) {Toast.makeText(MainActivity.this, sb.toString(), Toast.LENGTH_LONG).show();}}});}});}private void initParam() {String[] send = {"美团专送", "到店自取","骑手配送"};String[] feature = {"免配送费", "0元起送", "品牌商家", "点评高分", "跨天预定", "最新商家", "可开发票"};String[] activity = {"优惠商家", "首单立减", "满减优惠", "进店领券", "折扣商品", "第二份半价", "提前下单优惠", "满返代金券"};FilterTypeBean fb1 = new FilterTypeBean();fb1.setTypeName("配送");List<FilterTypeBean.Condition> childrenList = new ArrayList<>();for (int x = 0; x < send.length; x++) {FilterTypeBean.Condition cd = new FilterTypeBean.Condition();cd.setValue(send[x]);childrenList.add(cd);}fb1.setChildren(childrenList);FilterTypeBean fb2 = new FilterTypeBean();fb2.setTypeName("商家特色");List<FilterTypeBean.Condition> childrenList2 = new ArrayList<>();for (int x = 0; x < feature.length; x++) {FilterTypeBean.Condition cd = new FilterTypeBean.Condition();cd.setValue(feature[x]);childrenList2.add(cd);}fb2.setChildren(childrenList2);FilterTypeBean fb3 = new FilterTypeBean();fb3.setTypeName("优惠活动");List<FilterTypeBean.Condition> childrenList3 = new ArrayList<>();for (int x = 0; x < activity.length; x++) {FilterTypeBean.Condition cd = new FilterTypeBean.Condition();cd.setValue(activity[x]);childrenList3.add(cd);}fb3.setChildren(childrenList3);filterList.add(fb1);filterList.add(fb2);filterList.add(fb3);}

总结

这下不用烦恼在需要弹出框的时候到底该弹个什么样的dialog了，这三种弹出框应该能适应大部分的弹出框需求了
