Monitoring of Android off-screen and bright-screen

Use the method of dynamic registration broadcast to monitor the off-screen and bright-screen

1. Create a receiver

class ScreenStatusReceiver extends BroadcastReceiver {
​
    String SCREEN_ON = "android.intent.action.SCREEN_ON";
    String SCREEN_OFF = "android.intent.action.SCREEN_OFF";
​
    @Override
​
    public void onReceive(Context context, Intent intent) {
        if (SCREEN_ON.equals(intent.getAction())) {
            //屏幕亮做xxx操作
        } else if (SCREEN_OFF.equals(intent.getAction())) {
            //屏幕暗做xxx操作
        }
    }
}

2. Use receiver

private ScreenStatusReceiver mScreenStatusReceiver;

used in onCreateoronResume

private void registSreenStatusReceiver() {
    mScreenStatusReceiver = new ScreenStatusReceiver();
    IntentFilter screenStatusIF = new IntentFilter();
    screenStatusIF.addAction(Intent.ACTION_SCREEN_ON);
    screenStatusIF.addAction(Intent.ACTION_SCREEN_OFF);
    registerReceiver(mScreenStatusReceiver, screenStatusIF);
}

unlisten in onDestroyoronPause

unregisterReceiver(mScreenStatusReceiver);
