android4.4增加动态显示隐藏statusbar和禁止statusbar下拉功能
首先还是在设置->显示里加上图形界面
修改packages/apps/Settings/res/xml/display_settings.xml
增加
android:key="drop_statusbar"
android:title="@string/prohibit_statusbar_title"
android:persistent="false" />
android:key="hide_statusbar"
android:title="@string/hide_statusbar_title"
android:persistent="false" />修改packages/apps/Settings/res/values/strings.xml增加
Hide StatusBar
Prohibit statusbar drop-down修改packages/apps/Settings/src/com/android/settings/DisplaySettings.java增加
private static final String KEY_STATUSBAR_BAR_DROP = "drop_statusbar";
private static final String KEY_STATUSBAR_BAR_HIDE = "hide_statusbar";
public static String ACTION_SHOW_STATUS_BAR = "gzys.hclydao.action.show_status_bar";
public static String ACTION_HIDE_STATUS_BAR = "gzys.hclydao.action.hide_status_bar";
private CheckBoxPreference mDropSta; //add by hclydao
private CheckBoxPreference mHideSta; //add by hclydao增加初始化
mDropSta = (CheckBoxPreference) findPreference(KEY_STATUSBAR_BAR_DROP);
mDropSta.setPersistent(false);
mHideSta = (CheckBoxPreference) findPreference(KEY_STATUSBAR_BAR_HIDE);
mHideSta.setPersistent(false);在onCreate最后
navcheck = Settings.Global.getInt(resolver, Settings.Global.DROP_STATUSBAR,0);
if(navcheck == 1)
mDropSta.setChecked(true);
navcheck = Settings.Global.getInt(resolver, Settings.Global.HIDE_STATUSBAR,0);
if(navcheck == 1)
mHideSta.setChecked(true);基于上篇隐藏Navigationbar已经定义了navcheck
在onPreferenceTreeClick中增加判断
else if(preference == mDropSta) { //add by hclydao
boolean isCheck = mDropSta.isChecked();
Settings.Global.putInt(getContentResolver(), Settings.Global.DROP_STATUSBAR, isCheck ? 1 : 0);
} else if(preference == mHideSta) { //add by hclydao
boolean isCheck = mHideSta.isChecked();
Settings.Global.putInt(getContentResolver(), Settings.Global.HIDE_STATUSBAR, isCheck ? 1 : 0);
Intent mychange;
if(isCheck) {
mychange = new Intent(ACTION_HIDE_STATUS_BAR);
} else {
mychange = new Intent(ACTION_SHOW_STATUS_BAR);
}
getActivity().sendBroadcast(mychange);
}图形界面部分就修改完了，接着完善功能
修改frameworks/base/core/java/android/provider/Settings.java增加
public static final String HIDE_STATUSBAR = "hide_statusbar";
public static final String DROP_STATUSBAR = "drop_statusbar";保存全局设置
禁止statusbar下拉的完善
修改frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/phone/PanelBar.java增加
import android.provider.Settings;
import android.content.ContentResolver;
private Context mContext;//add by hclydao在public PanelBar(Context context, AttributeSet attrs) {最后增加
mContext = context;修改public PanelView selectPanelForTouch函数
public PanelView selectPanelForTouch(MotionEvent touch) {
final int N = mPanels.size();
int dropstatus = Settings.Global.getInt(mContext.getContentResolver(), Settings.Global.DROP_STATUSBAR,0);
if(dropstatus == 1) //add by hclydao
return null;//modify by hclydao
else
return mPanels.get((int)(N * touch.getX() / getMeasuredWidth()));
}修改frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/phone/PhoneStatusBarView.java增加
import android.provider.Settings;
import android.content.ContentResolver;
private Context mContext;//add by hclydao
修改函数public PanelView selectPanelForTouch最后的return
int dropstatus = Settings.Global.getInt(mContext.getContentResolver(), Settings.Global.DROP_STATUSBAR,0);
if(dropstatus == 1) //add by hclydao
return null;//modify by hclydao
else
return showSettings ? mSettingsPanel : mNotificationPanel;隐藏statusbar功能完善
修改frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/phone/PhoneStatusBar.java
增加
public static String ACTION_SHOW_STATUS_BAR = "gzys.hclydao.action.show_status_bar";
public static String ACTION_HIDE_STATUS_BAR = "gzys.hclydao.action.hide_status_bar";在addStatusBarWindow函数最后加上
//add by hclydao
IntentFilter filter = new IntentFilter();
filter.addAction(ACTION_HIDE_NAV_BAR);
filter.addAction(ACTION_SHOW_NAV_BAR);
filter.addAction(ACTION_SHOW_STATUS_BAR);
filter.addAction(ACTION_HIDE_STATUS_BAR);
mContext.registerReceiver(mHideNavBarReceiver, filter);
int navcheck = Settings.Global.getInt(mContext.getContentResolver(), Settings.Global.HIDE_STATUSBAR,0);
if(navcheck != 0)
showStatusBar(false);在destroy函数最后加上
mContext.unregisterReceiver(mHideNavBarReceiver);//hclydao文件最后增加
//add by hclydao
public void showStatusBar(boolean isshow) {
if(mStatusBarWindow != null) {/*
WindowManager.LayoutParams lp = (WindowManager.LayoutParams) mStatusBarWindow.getLayoutParams();
if(isshow)
lp.height = getStatusBarHeight();
else
lp.height = 0;
mWindowManager.updateViewLayout(mStatusBarWindow, lp);*/
mStatusBarWindow.setVisibility(isshow ? View.VISIBLE : View.GONE);
}
}
BroadcastReceiver mHideNavBarReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
if(intent.getAction().equals(ACTION_HIDE_NAV_BAR)) {
//hideNavBar();
} else if(intent.getAction().equals(ACTION_SHOW_NAV_BAR)) {
//showNavBar();
} else if(intent.getAction().equals(ACTION_SHOW_STATUS_BAR)) {
showStatusBar(true);
} else if(intent.getAction().equals(ACTION_HIDE_STATUS_BAR)) {
showStatusBar(false);
}
}
};修改frameworks/base/policy/src/com/android/internal/policy/impl/PhoneWindowManager.java增加
public static String ACTION_SHOW_STATUS_BAR = "gzys.hclydao.action.show_status_bar";
public static String ACTION_HIDE_STATUS_BAR = "gzys.hclydao.action.hide_status_bar";
int oStatusBarHeight;//add by hclydao基于前一篇隐藏Navigationbar中在 context.registerReceiver(mHideNavBarReceiver, filter);前增加
filter.addAction(ACTION_SHOW_STATUS_BAR);
filter.addAction(ACTION_HIDE_STATUS_BAR);在 hideNavBar();下增加
navcheck = Settings.Global.getInt(mContext.getContentResolver(), Settings.Global.HIDE_STATUSBAR,0);
if(navcheck != 0)
showStatusBar(false);在
mHideNavBarReceiver中增加判断
} else if(intent.getAction().equals(ACTION_SHOW_STATUS_BAR)) {
showStatusBar(true);
} else if(intent.getAction().equals(ACTION_HIDE_STATUS_BAR)) {
showStatusBar(false);增加showStatusBar函数
public void showStatusBar(boolean isshow) {
if(isshow) {
mStatusBarHeight = oStatusBarHeight;
} else {
if(mStatusBarHeight == 0)
return;
oStatusBarHeight = mStatusBarHeight;
mStatusBarHeight = 0;
}
updateRotation(false);
}效果图如下:
