如何在后台更改铃声模式（振动或静音） [英] how to change ringer mode in background(Vibrate or Silent)

问题描述

我正在尝试编写一个程序，用户可以在其中设置时间，以将振铃器模式更改为在后台振动或正常运行。当我设置开始时间后，它开始工作，但是在结束时，它没有改变，并且设备继续振动模式。我只想要
，在开始时电话会振动，在结束时电话会回到静音模式。

MainActivity。 java

 公共类MainActivity扩展了Activity {
 
 private PendingIntentendingIntent; 
私人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）; 
endingIntent = PendingIntent.getBroadcast（MainActivity.this，（int）System.currentTimeMillis（），myIntent，PendingIntent.FLAG_UPDATE_CURRENT）; 
 alarmManager.set（AlarmManager.RTC_WAKEUP，calendar.getTimeInMillis（），endingIntent）; 
 
 calendar.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）; 
endingIntent = PendingIntent.getBroadcast（MainActivity.this，（int）System.currentTimeMillis（），myIntent1，PendingIntent.FLAG_UPDATE_CURRENT）; 
 alarmManager.set（AlarmManager.RTC_WAKEUP，calendar1.getTimeInMillis（），endingIntent）; 
}} 
  

这是与BroadcastReceiver相关的类。

MyReceiver.java

 公共类MyReceiver扩展了BroadcastReceiver {
 
 @Override 
 public void onReceive（Context arg0，Intent intent）{
 // TODO自动生成的方法存根
 AudioManager audio =（AudioManager）arg0.getSystemService（Context .AUDIO_SERVICE）; 
 
开关（audio.getRingerMode（））{
 case AudioManager.RINGER_MODE_NORMAL：
 audio.setRingerMode（AudioManager.RINGER_MODE_VIBRATE）; 
 Log.d（ MODE，是正常的）; 
 Log.d（ MODE， is vibrate）; 
休息时间； 
 
 case AudioManager.RINGER_MODE_SILENT：
 audio.setRingerMode（AudioManager.RINGER_MODE_VIBRATE）; 
 Log.d（ MODE，保持沉默）; 
 Log.d（ MODE， is vibrate）; 
休息时间； 
} 
}} 
  

MyReceiver1.java

 公共类MyReceiver1扩展了BroadcastReceiver {
 
 @Override 
 public void onReceive（Context context ，Intent intent）{
 AudioManager audio =（AudioManager）context.getSystemService（Context.AUDIO_SERVICE）; 
 // TODO自动生成的方法存根
 switch（audio.getRingerMode（））{
 case AudioManager.RINGER_MODE_NORMAL：
 audio.setRingerMode（AudioManager.RINGER_MODE_SILENT）; 
 Log.d（ MODE，是正常的）; 
 Log.d（ MODE，是沉默的）; 
休息时间； 
} 
 
 case AudioManager.RINGER_MODE_VIBRATE：
 audio.setRingerMode（AudioManager.RINGER_MODE_SILENT）; 
 Log.d（ MODE，被振动）; 
 Log.d（ MODE，是沉默的）; 
休息时间； 
} 
}} 
  

我宣布

 < receiver android：name =。MyReceiver> 
<意图过滤器> 
< action android：name = android.media.RINGER_MODE_CHANGED /> 
< / intent-filter> 
< / receiver> 
 
< receiver android：name =。MyReceiver1> 
<意图过滤器> 
< 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。

解决方案

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

< pre class = snippet-code-js lang-js prettyprint-override> < receiver android：name =。MyReceiver> <意图过滤器> < action android：name = android.media.RINGER_MODE_CHANGED /> < / intent-filter> < / receiver>

I'm trying to write a program in which user can set time that will change ringer mode to vibrate or normal in background. When I set the start time it's working but at the end time it's not changing and device continuing vibrate mode. I just want, at the start time phone would be in vibrate and at end time phone would go back into the silent mode.

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);
}}

and these are related BroadcastReceiver class..

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;
    }
}}

and I declared

    <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>

in my manifest file.

Please help me to solve this issue. Thanks.

解决方案

Dont't use both the receiver (MyReceiver and Myreceiver1) use single MyReceiver.

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