Question

我试图编写一个程序，用户可以在其中设置将振铃模式改变为背景振动或正常的时间。当我设定开始时间时，它会工作但在结束时它没有改变，设备继续振动模式。我只想要，在开始时手机会振动，在结束时手机会重新进入静音模式。

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;
    }
}}

我宣布了

    <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。感谢。

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>
