为了设置状态栏，会设置透明标签，而华为手机的虚拟按键有可能会遮挡底部导航栏。
requestWindowFeature(Window.FEATURE_NO_TITLE);super.onCreate(savedInstanceState);setContentView(R.layout.activity_ad_main);getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
不要设置FLAG_TRANSLUCENT_NAVIGATION。
由于项目中WebView输入数据，软键盘不会顶上布局，遮盖住页面，使用下边此类解决冲突后出现底部导航栏被遮挡的问题。
/*** webview-软键盘-冲突*/public class KeyBoardListenerManager {private Activity activity;private View mChildOfContent;private int usableHeightPrevious;private FrameLayout.LayoutParams frameLayoutParams;private static KeyBoardListenerManager keyBoardListener;public static KeyBoardListenerManager newInstance(Activity activity) {keyBoardListener = new KeyBoardListenerManager(activity);return keyBoardListener;}public KeyBoardListenerManager(Activity activity) {super();// TODO Auto-generated constructor stubthis.activity = activity;}public void init() {FrameLayout content = (FrameLayout) activity.findViewById(android.R.id.content);mChildOfContent = content.getChildAt(0);mChildOfContent.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {public void onGlobalLayout() {possiblyResizeChildOfContent();}});frameLayoutParams = (FrameLayout.LayoutParams) mChildOfContent.getLayoutParams();}private void possiblyResizeChildOfContent() {int usableHeightNow = computeUsableHeight();if (usableHeightNow != usableHeightPrevious) {int usableHeightSansKeyboard = mChildOfContent.getRootView().getHeight();int heightDifference = usableHeightSansKeyboard - usableHeightNow;if (heightDifference > (usableHeightSansKeyboard / 4)) {// keyboard probably just became visibleframeLayoutParams.height = usableHeightSansKeyboard- heightDifference;} else {// keyboard probably just became hiddenframeLayoutParams.height = usableHeightSansKeyboard;}mChildOfContent.requestLayout();usableHeightPrevious = usableHeightNow;}}private int computeUsableHeight() {Rect r = new Rect();mChildOfContent.getWindowVisibleDisplayFrame(r);return (r.bottom - r.top);}}
调用方式为：KeyBoardListenerManager.newInstance(this).init();
出现华为虚拟按键冲突问题：
解决方案使用下面此类，此类主要作为封装处理特殊手机的工具类。

最终得以解决。
请在加载布局文件后使用。
调用方法：
/*** 虚拟按键-tangZd*/private void doSpecialiSomethingAsVirtualBar(){KeyBoardListenerManager.newInstance(this).init();if (PhoneSystemManager.AndroidWorkaround.checkDeviceHasNavigationBar(this)) {PhoneSystemManager.AndroidWorkaround.assistActivity(findViewById(android.R.id.content));ViewStub stub = (ViewStub) findViewById(R.id.view_stub);stub.inflate();View enuiStubView = this.findViewById(R.id.enuiNatView);LinearLayout.LayoutParams zLayoutParams = (LinearLayout.LayoutParams) enuiStubView.getLayoutParams();zLayoutParams.height = PhoneSystemManager.AndroidWorkaround.getVirtualBarHeigh(this);enuiStubView.setLayoutParams(zLayoutParams);}}
需要在对应布局的最底部增加布局：
<ViewStub android:id="@+id/view_stub"android:layout_width="match_parent"android:layout_height="wrap_content"android:layout="@layout/enui_layout"/>
enui_layout布局文件代码:
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="/apk/res/android"android:orientation="vertical"android:background="@color/black"android:layout_width="match_parent"android:layout_height="wrap_content"><View android:id="@+id/enuiNatView"android:background="@color/black"android:layout_width="match_parent"android:layout_height="wrap_content"/></LinearLayout>
