java - 重复音频文件，并在任务改变时停止

Question

我想每 1 分钟重复播放一次“正在搜索”的音频文件。当 CASE_STATUS_SEARCHING 将更改为其他时，我该如何实现它以停止此文件？我使用了TIMER和SOUNDPOOL:

public class Player { 
private static SoundPool soundPool;
private static int searching;
final Timer timer = new Timer();


public void searching () {
    timer.schedule(new TimerTask() {
                       @Override
                       public void run() {
                           soundPool.play(searching, 1.0f, 1.0f, 1, 0, 1.0f);
                       }
                   }, 60000);
}

//我在这里开始线程:

public class Locator BroadcastReceiver extends BroadcastReceiver {
@Override
public void onReceive (Context context, Intent intent) {
final String action = intent.getAction();

switch (newStatus) {
    case STATUS_SEARCHING:
                        stateStr = getString(R.string.Scanning);
                        tvStatus.setText(R.string.Scanning);
                        Player.searching();
                        break;
}

我自己解决了这个问题，几乎没有得到 stackoverflow 的帮助。

public void playStillSearching() {

    if (handler == null) {
            handler = new Handler();
            handler.postDelayed(runnable = new Runnable() {
                @Override
                public void run() {
                    soundPool.play(stillSearching, 1.0f, 1.0f, 1, 0, 1.0f);
                    handler.postDelayed(this, 3000);
                }
            }, 3000);
    }
}

public void stopSpeak() {

    if (handler != null) {
        handler.removeCallbacks(runnable);
    }
}

然后我将这些应用到我的 Activity 中。
