MTK Android12 隐藏顶部状态栏

1、解决路径：

	（1）vendor/mediatek/proprietary/packages/apps/SystemUI/src/com/android/systemui/statusbar/phone/StatusBar.java（2）vendor/mediatek/proprietary/packages/apps/SystemUI/src/com/android/systemui/statusbar/phone/StatusBarWindowController.java

2、方法：

（1）在StatusBar.java类的start()中：

RegisterStatusBarResult result = null;try {result = mBarService.registerStatusBar(mCommandQueue);} catch (RemoteException ex) {ex.rethrowFromSystemServer();}createAndAddWindows(result);// add startmStatusBarWindowController.setBarVisibility(View.GONE);// add endif (mWallpaperSupported) {// Make sure we always have the most current wallpaper info.IntentFilter wallpaperChangedFilter = new IntentFilter(Intent.ACTION_WALLPAPER_CHANGED);mBroadcastDispatcher.registerReceiver(mWallpaperChangedReceiver, wallpaperChangedFilter,null /* handler */, UserHandle.ALL);mWallpaperChangedReceiver.onReceive(mContext, null);} else if (DEBUG) {Log.v(TAG, "start(): no wallpaper service ");}

（2）在StatusBarWindowController.java类中

public void setBarVisibility(int visibility) {mStatusBarView.setVisibility(visibility);
}
