Java MediaPlayer类型中方法create（Context，int）的错误不适用于参数（AlarmReceiver，int）

我需要解决这个问题：

public class AlarmReceiver extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {
    Toast.makeText(context, "Time is up!!!!.", Toast.LENGTH_LONG).show();
    // Vibrate the mobile phone
    Vibrator vibrator = (Vibrator) context.getSystemService(Context.VIBRATOR_SERVICE);
    vibrator.vibrate(2000);
    MediaPlayer mp = MediaPlayer.create(this, R.raw.abc1);
    mp.start();
 }
}

BroadcastReceiver

不是

Context

的子类。因此请更改此项

MediaPlayer mp = MediaPlayer.create(this, R.raw.abc1);

进入

在“onReceive”方法中，此指的是AlarmReceiver，而不是活动上下文。因此，请改为：

MediaPlayer mp = MediaPlayer.create(context, R.raw.abc1);

MediaPlayer mp = MediaPlayer.create(context, R.raw.abc1);
