确定的addAction点击Android的通知 [英] Determine addAction click for Android notifications

问题描述

我试图用新的通知界面。我已经添加了3个按钮的通知，我想的东西保存到我的数据库，一旦他们每个人的点击。

I'm trying to use the new notifications interface. I've added 3 buttons to the notifications, and I want to save something to my database once each of them is clicked.

本身运作良好，并显示调用时的通知，我只是不知道如何捕捉每三个不同的按钮点击。

The notification itself works well and is shown when called, I just don't know how to capture each of the three different button clicks.

我使用了一个的BroadcastReceiver 赶点击，但我不知道怎么告诉哪个按钮被点击。

I'm using a BroadcastReceiver to catch the clicks, but I don't know how to tell which button was clicked.

这是的addAction 的code（我已经排除了通知的其余部分，因为它的工作好） -

This is the code of AddAction(I've excluded the rest of the notification, as it's working well) -

    //Yes intent
    Intent yesReceive = new Intent();  
    yesReceive.setAction(CUSTOM_INTENT);
    Bundle yesBundle = new Bundle();            
    yesBundle.putInt("userAnswer", 1);//This is the value I want to pass
    yesReceive.putExtras(yesBundle);
    PendingIntent pendingIntentYes = PendingIntent.getBroadcast(this, 12345, yesReceive, PendingIntent.FLAG_UPDATE_CURRENT);
    mBuilder.addAction(R.drawable.calendar_v, "Yes", pendingIntentYes);

    //Maybe intent
    Intent maybeReceive = new Intent();  
    maybeReceive.setAction(CUSTOM_INTENT);
    Bundle maybeBundle = new Bundle();            
    maybeBundle.putInt("userAnswer", 3);//This is the value I want to pass
    maybeReceive.putExtras(maybeBundle);
    PendingIntent pendingIntentMaybe = PendingIntent.getBroadcast(this, 12345, maybeReceive, PendingIntent.FLAG_UPDATE_CURRENT);
    mBuilder.addAction(R.drawable.calendar_question, "Partly", pendingIntentMaybe);

    //No intent
    Intent noReceive = new Intent();  
    noReceive.setAction(CUSTOM_INTENT);
    Bundle noBundle = new Bundle();            
    noBundle.putInt("userAnswer", 2);//This is the value I want to pass
    noReceive.putExtras(noBundle);
    PendingIntent pendingIntentNo = PendingIntent.getBroadcast(this, 12345, noReceive, PendingIntent.FLAG_UPDATE_CURRENT);
    mBuilder.addAction(R.drawable.calendar_x, "No", pendingIntentNo);

这是的code中的的BroadcastReceiver -

This is the code of the BroadcastReceiver-

 public class AlarmReceiver extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {
    Log.v("shuffTest","I Arrived!!!!");
     //Toast.makeText(context, "Alarm worked!!", Toast.LENGTH_LONG).show();

    Bundle answerBundle = intent.getExtras();
    int userAnswer = answerBundle.getInt("userAnswer");
    if(userAnswer == 1)
    {
        Log.v("shuffTest","Pressed YES");
    }
    else if(userAnswer == 2)
    {
        Log.v("shuffTest","Pressed NO");
    }
    else if(userAnswer == 3)
    {
        Log.v("shuffTest","Pressed MAYBE");
    }

}           
}

我已经注册了的BroadcastReceiver 在清单中。 另外，我想提的是，的BroadcastReceiver 被称为当我点击通知中的按钮中的一个，但目的总是包含'2'的额外费用。

I've registered the BroadcastReceiver in the Manifest. Also, I want to mention that the BroadcastReceiver is called when I click one of the buttons in the notification, but the intent always includes an extra of '2'.

这是notifcation iteslf -

This is the notifcation iteslf -

推荐答案

这是因为你使用<一个href="http://developer.android.com/reference/android/app/PendingIntent.html#FLAG_UPDATE_CURRENT">FLAG_UPDATE_CURRENT与具有相同的操作意图

It's because you're using FLAG_UPDATE_CURRENT with Intents that have the same action

从文档：

如果所描述的PendingIntent已经存在，那么保留它，但它与什么是在这个新的意图取代其额外数据。

if the described PendingIntent already exists, then keep it but its replace its extra data with what is in this new Intent.

在指定 pendingIntentMaybe 和 pendingIntentNo ，系统将使用 PendingIntent 为 pendingIntentYes ，但它覆盖的花絮。因此，所有三个变量指向同一个对象，指定的最后一个演员是为 pendingIntentNo 。

When you specify pendingIntentMaybe and pendingIntentNo, the system uses the PendingIntent created for pendingIntentYes, but it overwrites the extras. Thus, all three variables refer to the same object, and the last extras specified were for pendingIntentNo.

您应该为每个替代操作意图。你仍然可以有一个的BroadcastReceiver ，只是把它拦截所有三个动作。这将是减少混乱语义以及：）

You should specify an alternative action for each Intent. You can still have one BroadcastReceiver, and just have it intercept all three actions. This would be less confusing semantically as well :)

您通知海报：

//Yes intent
Intent yesReceive = new Intent();  
yesReceive.setAction(YES_ACTION);
PendingIntent pendingIntentYes = PendingIntent.getBroadcast(this, 12345, yesReceive, PendingIntent.FLAG_UPDATE_CURRENT);
mBuilder.addAction(R.drawable.calendar_v, "Yes", pendingIntentYes);

//Maybe intent
Intent maybeReceive = new Intent();  
maybeReceive.setAction(MAYBE_ACTION);
PendingIntent pendingIntentMaybe = PendingIntent.getBroadcast(this, 12345, maybeReceive, PendingIntent.FLAG_UPDATE_CURRENT);
mBuilder.addAction(R.drawable.calendar_question, "Partly", pendingIntentMaybe);

//No intent
Intent noReceive = new Intent();  
noReceive.setAction(NO_ACTION);
PendingIntent pendingIntentNo = PendingIntent.getBroadcast(this, 12345, noReceive, PendingIntent.FLAG_UPDATE_CURRENT);
mBuilder.addAction(R.drawable.calendar_x, "No", pendingIntentNo);

您接收器：

@Override
public void onReceive(Context context, Intent intent) {
    String action = intent.getAction();

    if(YES_ACTION.equals(action)) {
        Log.v("shuffTest","Pressed YES");
    } else if(MAYBE_ACTION.equals(action)) {
        Log.v("shuffTest","Pressed NO");
    } else if(NO_ACTION.equals(action)) {
        Log.v("shuffTest","Pressed MAYBE");
    }
}
