SurfaceView? SurfaceHolder? MediaPlayer? ? Service? ? ? BroadcastReceiver? ? KeyguardManager? ? PowerManager

思路：啟動一個服務，監聽滅屏廣播，當收到廣播的時候，點亮屏幕，禁用鎖屏，調用使用SurfaceView播放視頻。

1.啟動一個服務

Intent intent = new Intent();

intent.setClass(this,LockService.class);

startService(intent);

2.LockService onCreate中注冊監聽ACTION_SCREEN_OFF

final IntentFilter filter = new IntentFilter();

filter.addAction(Intent.ACTION_SCREEN_OFF);

registerReceiver(mReceiver, filter);

3.LockService 的內部監聽類

private final BroadcastReceiver mReceiver = new BroadcastReceiver() {

@Override

public void onReceive(Context context, Intent intent) {

final String action = intent.getAction();

if (Intent.ACTION_SCREEN_OFF.equals(action)) {

Log.d("yzy","screen_off...");

if(HelloActivity.isScreenOff == false){

wakeUpScreen();

Intent intent1? = new Intent();

intent1.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

intent1.setClass(LockService.this, HelloActivity.class);//啟動屏保界面

startActivity(intent1);

HelloActivity.isScreenOff = true;

}

}

}

? ? };
