我想知道是否显示 SystemUI 和 Listenering。窗口在服务中创建

@Override

super.onCreate();
Log.i(TAG, "onCreate view");

}
@Override

int i = super.onStartCommand(intent, flags, startId);

Log.e(TAG, "mSystemUiVisibility ="+mSystemUiVisibility);
WindowManager.LayoutParams layoutParams = mWindow.getAttributes();
layoutParams.x = 0;

return layoutParams;
}
public Window addWindow(View paramView, int width, int height,

WindowManager.LayoutParams layoutParams = createLayoutParams();
Window localWindow = PolicyManager.makeNewWindow(this.mContext);
if (localWindow != null) {

localWindow.requestFeature(Window.FEATURE_NO_TITLE);
localWindow.setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
layoutParams.width = width;
layoutParams.height = height;
layoutParams.type = type;
layoutParams.format= PixelFormat.TRANSPARENT;
layoutParams.flags = (LayoutParams.FLAG_NOT_FOCUSABLE | layoutParams.flags);
localWindow.setAttributes(layoutParams);
localWindow.setContentView(paramView);
View localView = localWindow.getDecorView();
if (localView != null) {
localView.setVisibility(View.VISIBLE);
this.mWindowManager.addView(localView, layoutParams);
}
return localWindow;
}
return null;
}
@Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
return null;
}
@Override
public void onDestroy() {
if (mWindow != null) {
mWindowManager.removeView(mWindow.getDecorView());
mWindow = null;
}
super.onDestroy();
}
}
当我启动服务时,其他应用程序是否更改为全屏,我无法获取日志“systemUI onSystemUiVisibilityChange =”
有人可以解释这种行为吗?为什么不能听变化?
