我正在尝试编写一个程序，用户可以在其中设置时间，将铃声模式更改为在后台振动或正常。当我设置开始时间它正在工作但在结束时间它没有改变并且设备继续振动模式。我只想，在开始时手机会振动，在结束时手机会回到静音模式。

MainActivity.java

public class MainActivity extends Activity {

private PendingIntent pendingIntent;
private AlarmManager alarmManager;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
    Calendar calendar = Calendar.getInstance();
    Calendar calendar1 = Calendar.getInstance();


    calendar.set(Calendar.HOUR_OF_DAY, 4);
    calendar.set(Calendar.MINUTE, 37);
    calendar.set(Calendar.AM_PM,Calendar.AM);

    Intent myIntent = new Intent(MainActivity.this, MyReceiver.class);
    pendingIntent = PendingIntent.getBroadcast(MainActivity.this, (int)System.currentTimeMillis(), myIntent,PendingIntent.FLAG_UPDATE_CURRENT);
    alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);

    calendar1.set(Calendar.HOUR_OF_DAY, 4);
    calendar1.set(Calendar.MINUTE, 38);
    calendar1.set(Calendar.AM_PM,Calendar.AM);

    Intent myIntent1 = new Intent(MainActivity.this, MyReceiver1.class);
    pendingIntent = PendingIntent.getBroadcast(MainActivity.this, (int)System.currentTimeMillis(), myIntent1,PendingIntent.FLAG_UPDATE_CURRENT);
    alarmManager.set(AlarmManager.RTC_WAKEUP, calendar1.getTimeInMillis(), pendingIntent);
}}

这些是相关的 BroadcastReceiver 类..

MyReceiver.java

public class MyReceiver extends BroadcastReceiver{

@Override
public void onReceive(Context arg0, Intent intent) {
    // TODO Auto-generated method stub
    AudioManager audio = (AudioManager)arg0.getSystemService(Context.AUDIO_SERVICE);

    switch(audio.getRingerMode()){
    case AudioManager.RINGER_MODE_NORMAL :
        audio.setRingerMode(AudioManager.RINGER_MODE_VIBRATE);
        Log.d("MODE", "was normal");
        Log.d("MODE", "is vibrate");
        break;

    case AudioManager.RINGER_MODE_SILENT :
        audio.setRingerMode(AudioManager.RINGER_MODE_VIBRATE);
        Log.d("MODE", "was silent");
        Log.d("MODE", "is vibrate");
        break;
    }
}}

MyReceiver1.java

public class MyReceiver1 extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {
    AudioManager audio=(AudioManager)context.getSystemService(Context.AUDIO_SERVICE);
    // TODO Auto-generated method stub
    switch(audio.getRingerMode()){
    case AudioManager.RINGER_MODE_NORMAL :
        audio.setRingerMode(AudioManager.RINGER_MODE_SILENT);
        Log.d("MODE", "was normal");
        Log.d("MODE", "is silent");
        break;
    }

    case AudioManager.RINGER_MODE_VIBRATE :
        audio.setRingerMode(AudioManager.RINGER_MODE_SILENT);
        Log.d("MODE", "was vibrate");
        Log.d("MODE", "is silent");
        break;
    }
}}

我宣布

    <receiver android:name=".MyReceiver">  
        <intent-filter>  
            <action android:name="android.media.RINGER_MODE_CHANGED" /> 
        </intent-filter>  
    </receiver>

    <receiver android:name=".MyReceiver1">  
        <intent-filter>  
            <action android:name="android.media.RINGER_MODE_CHANGED" /> 
        </intent-filter>  
    </receiver>

在我的清单文件中。

请帮我解决这个问题。谢谢。

不要同时使用接收器（MyReceiver 和 Myreceiver1）使用单个 MyReceiver。

<receiver android:name=".MyReceiver">  
        <intent-filter>  
            <action android:name="android.media.RINGER_MODE_CHANGED" /> 
        </intent-filter>  
    </receiver>
