Question

我有一个应用程序，当特定文本进入时会创建声音通知。为此，我检测当前的ringerMode，将ringerMode更改为正常，播放声音，然后快速将铃声恢复为原始状态设置。这是代码：

public static AudioManager audio;

    audio = (AudioManager) this.getSystemService(Context.AUDIO_SERVICE);

ringMode = audio.getRingerMode();
        if (ringMode < 2)
        //Checks to see if the phones ringer is set to silent, or vibrate
            audio.setRingerMode(2);

        //vibrates phone in a pattern
        long[] pattern = {0, 25};
        //long[] pattern = {0, 1000, 100, 100, 100, 100, 100, 1000}; 
        v.vibrate(pattern, -1); 
        final int HELLO_ID = 1;
        mNotificationManager.notify(HELLO_ID, notification);

        //delays return back to original volume so notification can be heard
        Handler handler = new Handler();  
        handler.postDelayed(new Runnable() {  
             public void run() {  
                 audio.setRingerMode(ringMode); 
             }  
        }, 4000);
        }

这在活动中完全正常，但在此通知服务中没有，并且当前放在onStart方法中。使用权限android：name =“android.permission.MODIFY_AUDIO_SETTINGS”也已添加到清单中。有任何想法吗？感谢

不是解决这个问题的方法，但我意识到我应该调整一个Notification卷流。使用完全相同的代码，Notify类现在可以正常工作。

if (startSound)
        {   
            //This sound plays using the ringer volume
            //notification.sound = Uri.parse("android.resource://itp.uts.program/" + R.raw.pager);

            //Sets ringer temporarily to active, so notification is heard
            audio.setStreamVolume(5, 3, 0); 

            //vibrates phone in a pattern
            long[] pattern = {0, 25};
            //long[] pattern = {0, 1000, 100, 100, 100, 100, 100, 1000}; 
            v.vibrate(pattern, -1); 
        }
        //Creates the notification
        mNotificationManager.notify(HELLO_ID, notification);

        if (startSound)
        {
        //delays return back to original volume so notification can be heard
        Handler handler = new Handler();  
        handler.postDelayed(new Runnable() {  
             public void run() {  
                 audio.setStreamVolume(5, streamVolume, 0); 
             }  
        }, 7000);
        }

访问振铃模式在服务中不起作用
