我正在做一个应用,该应用需要通知正在通话的用户通话时间很长…
我正在执行所有操作,并在适当的时间发出了通知(我可以在状态栏上看到它),但是没有声音.如果没有电话时我发出通知电话,则会播放声音.
我的通知如下所示：
NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
int icon = R.drawable.icon;
CharSequence tickerText = "Hello From CallTimerService";
long when = System.currentTimeMillis();
Notification notification = new Notification(icon,tickerText,when);
Context context = getApplicationContext();
CharSequence contentTitle = "My notification";
CharSequence contentText = "ss";
Intent notificationIntent = new Intent(this,CallTimer.class);
PendingIntent contentIntent = PendingIntent.getActivity(this,notificationIntent,0);
notification.setLatestEventInfo(context,contentTitle,contentText,contentIntent);
notification.defaults = Notification.DEFAULT_SOUND;
notification.flags |= Notification.FLAG_AUTO_CANCEL;
mNotificationManager.notify(2,notification);
我也尝试使用AudioManager.STREAM_来更改notification.audioStreamType,但是没有运气.
请问现在有身体怎么做？或只是个好主意,下一步该怎么做….
最佳答案
我的应用程序中有一个选项,可以在用户通话时播放声音.您要做的就是使用媒体播放器播放声音.这是我的代码：
if(callStateIdle){
notification.sound = Uri.parse(notificationSound);
}else{
new playNotificationMediaFileAsyncTask().execute(notificationSound);
}
这是异步任务：
private static class playNotificationMediaFileAsyncTask extends AsyncTask<String,Void,Void> {
protected Void doInBackground(String... params) {
MediaPlayer mediaPlayer = null;
try{
mediaPlayer = new MediaPlayer();
mediaPlayer.setLooping(false);
mediaPlayer.setDataSource(_context,Uri.parse(params[0]));
mediaPlayer.prepare();
mediaPlayer.start();
mediaPlayer.setOnCompletionListener(new OnCompletionListener(){
public void onCompletion(MediaPlayer mediaPlayer) {
mediaPlayer.release();
mediaPlayer = null;
}
});
return null;
}catch(Exception ex){
Log.e("ERROR: " + ex.toString());
mediaPlayer.release();
mediaPlayer = null;
return null;
}
}
protected void onPostExecute(Void result) {
//Do Nothing
}
}
到目前为止,这对我来说效果很好.
