MainActivity中

public class MainActivity extends Activity {

    private WakeAndLockReceiver wakeAndLockReceiver;
  
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
  
        //注册亮屏和息屏的BroadcastReceiver
        wakeAndLockReceiver = new WakeAndLockReceiver();
        IntentFilter intentFilter = new IntentFilter();
        intentFilter.addAction(Intent.ACTION_SCREEN_ON);
        intentFilter.addAction(Intent.ACTION_SCREEN_OFF);
        registerReceiver(wakeAndLockReceiver,intentFilter);
    }

    //  继承BroadcastReceiver，实现onReceive()：接收到广播后的处理逻辑
    class WakeAndLockReceiver extends BroadcastReceiver {
        @Override
        public void onReceive(Context context, Intent intent) {
            if (intent == null) return;
            String action = intent.getAction();//action
            if (Intent.ACTION_SCREEN_ON.equals(action)) {
                Log.d("wpz", "onReceive: wake");
            } else if (Intent.ACTION_SCREEN_OFF.equals(action)) {
                Log.d("wpz", "onReceive: Lock");
            } else {
                return;
            }
        }
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        //取消注册
        unregisterReceiver(wakeAndLockReceiver);
    }
}

AndroidManifest.xml中

<!--声明权限-->
<uses-permission android:name="android.permission.WAKE_LOCK" />

结果
