Android 锁定屏幕上的活动不适用于全屏

下面是我在onStart命令中的代码：

WindowManager mWindowManager = (WindowManager)getSystemService(WINDOW_SERVICE);
View mView = mInflater.inflate(R.layout.mylockscreenlayout, null);
final WindowManager.LayoutParams mLayoutParams = new WindowManager.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.MATCH_PARENT,WindowManager.LayoutParams.TYPE_SYSTEM_ERROR,WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED
                | WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD
                | WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON
                | WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON ,
        PixelFormat.TRANSLUCENT);
mWindowManager.addView(mView, mLayoutParams);

并添加到清单中

    <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />
    <service android:name=".LockOverlayService" 
             android:enabled="true"
             android:exported="false" 
             android:process=":overlayservice" />

在这种情况下，我无法通过覆盖整个手机屏幕来获得全屏锁屏布局，因此顶部状态栏是可见的。有人建议解决方案让我的活动全屏覆盖整个手机屏幕。

将系统可见性添加到主视图，然后将此mView添加到窗口管理器中，如：

WindowManager mWindowManager = (WindowManager)getSystemService(WINDOW_SERVICE);
        View mView = mInflater.inflate(R.layout.mylockscreenlayout, null);
        final WindowManager.LayoutParams mLayoutParams = new WindowManager.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
                ViewGroup.LayoutParams.MATCH_PARENT,WindowManager.LayoutParams.TYPE_SYSTEM_ERROR,WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED
                | WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD
                | WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON
                | WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON ,
                PixelFormat.TRANSLUCENT);
        mView.setSystemUiVisibility(
                View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                        | View.SYSTEM_UI_FLAG_FULLSCREEN
                        | View.SYSTEM_UI_FLAG_VISIBLE
                        | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
        );
        mView.setVisibility(View.VISIBLE);
        mWindowManager.addView(mView, mLayoutParams);
