Question

以下是 OnstartCommand ：

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 Manifest

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

通过覆盖移动设备的整个显示，我没有通过锁定屏幕获得整个屏幕的布局，通过这个顶部状态栏是可见的。任何人建议解决方案让我的活动全屏覆盖整个移动屏幕。

为主视图添加系统可见性，然后将此mView添加到窗口管理器，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);

检查一下，让我知道它是否有效？

锁定屏幕上的活动不会全屏显示
