android - 确定 Android 通知的 addAction 点击

Question

我正在尝试使用新的通知界面。我在通知中添加了 3 个按钮，我想在单击每个按钮后将一些内容保存到我的数据库中。

通知本身运行良好，并在调用时显示，我只是不知道如何捕获三个不同按钮单击中的每一个。

我正在使用 BroadcastReceiver 来捕捉点击，但我不知道如何判断点击了哪个按钮。

这是AddAction的代码(我已经排除了通知的其余部分，因为它运行良好) -

    //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BroadcastReceiver的代码-

 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");
    }

}           
}

我已经在 Manifest 中注册了 BroadcastReceiver。 另外，我想提一下，当我单击通知中的一个按钮时会调用 BroadcastReceiver，但 Intent 始终包含额外的“2”。

这是因为您使用的是 FLAG_UPDATE_CURRENT具有相同 Action 的 Intent

来自文档:

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

当您指定 pendingIntentMaybe 和 pendingIntentNo 时，系统使用为 pendingIntentYes 创建的 PendingIntent，但它会覆盖额外的。因此，所有三个变量都引用同一个对象，并且最后指定的附加对象是 pendingIntentNo。

您应该为每个 Intent 指定一个替代操作。您仍然可以拥有一个 BroadcastReceiver，并让它拦截所有三个 Action 。这在语义上也不会那么困惑:)

您的通知海报:

//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);

你的接收者:

@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");
    }
}
