Question

我开发了一个应用程序，用户可以为指定的任务设置铃声

这里是appointment.class的代码：

    Intent intent = new Intent(RingtoneManager.ACTION_RINGTONE_PICKER);
    intent.putExtra(RingtoneManager.EXTRA_RINGTONE_TYPE,  
    RingtoneManager.TYPE_NOTIFICATION);
    intent.putExtra(RingtoneManager.EXTRA_RINGTONE_TITLE, "Select Tone");
    intent.putExtra(RingtoneManager.EXTRA_RINGTONE_EXISTING_URI, (Uri)              
    null);
    this.startActivityForResult(intent, 5);

并且Activity扩展到BroadcastReceiver

@Override
public void onReceive(Context context, Intent intent) {

    switch (getResultCode()){
        case AppointmentPage.RESULT_OK:
            Log.e("Sample","asdas");
            break;
    }

我的问题是我在Logcat中看不到Sample。我怎么能看到它？

您应该在活动中使用onActivityResults为用户保存他的偏好，然后在onRecieve中检索它以使用它

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
 super.onActivityResult(requestCode, resultCode, data);

switch (requestCode) {
   case 5: {
      if (resultCode == RESULT_OK ) {
          Uri uri = data.getParcelableExtra(RingtoneManager.EXTRA_RINGTONE_PICKED_URI);
        if (uri != null) {
           SharedPreferences sharedPreference = getSharedPreferences("key_for_shared_preference",MODE_PRIVATE);
           SharedPreferences.Editor editor = sharedPreference.edit();
           editor.putString("selected_ringtone_uri",uri.toString());
           editor.apply();
          }
          break;
      }
   }
 }
}

为此，您需要从同一活动中激活意图

Intent intent = new Intent(RingtoneManager.ACTION_RINGTONE_PICKER);
intent.putExtra(RingtoneManager.EXTRA_RINGTONE_TYPE,  
RingtoneManager.TYPE_NOTIFICATION);
intent.putExtra(RingtoneManager.EXTRA_RINGTONE_TITLE, "Select Tone");
intent.putExtra(RingtoneManager.EXTRA_RINGTONE_EXISTING_URI, (Uri)              
null);
startActivityForResult(intent, 5);

每次都在onReceive的broadcastReceiver中检索它

@Override
public void onReceive(Context context, Intent intent) {

   SharedPreferences sharedPreference = getSharedPreferences("key_for_shared_preference",MODE_PRIVATE);
   String ringtoneUri = sharedPreference.getString("selected_ringtone_uri","");
   if(!ringtoneUri.contentEquals("")){
       Log.d("ringtone uri",ringtoneUri);
   }
}

如何在通知中设置铃声
