android 华为虚拟按键适配
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 stub
this.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 visible
frameLayoutParams.height = usableHeightSansKeyboard
- heightDifference;
} else {
// keyboard probably just became hidden
frameLayoutParams.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:
<LinearLayout xmlns:android="http://schemas.android.com/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>
