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，并且每次单击它们时我都会将某些内容保存到我的数据库中。

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

我使用BroadcastReceiver来捕捉点击，但我不知道如何判断哪个按钮被点击。

这是AddAction代码（我已经排除该通知的其余部分，因为它的运作良好） -

//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"); 
    } 

}   
} 

我已经在清单中注册了BroadcastReceiver。 另外，我想提到的是，当我单击通知中的某个按钮时，会调用BroadcastReceiver，但意图总是包含额外的'2'。

Answer 1

这是因为你使用FLAG_UPDATE_CURRENT与具有相同的作用

从文档意图：

如果所描述的PendingIntent已经存在，然后保留它，但是用这个新的Intent替换它的额外数据。

当您指定pendingIntentMaybe和pendingIntentNo，系统将使用pendingIntentYes创建PendingIntent，但它覆盖的花絮。因此，所有三个变量都指向相同的对象，并且最后指定的附加值为pendingIntentNo。

您应该为每个Intent指定一个替代操作。你仍然可以有一个BroadcastReceiver，并且只需要拦截所有三个动作。这将是减少混乱语义以及:)

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); 

接收机：

@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"); 
    } 
}   

Answer 2

在我的情况下，它加入的意图过滤

后为我工作

<receiver android:name=".AlarmReceiver"> 
     <intent-filter> 
      <action android:name="YES_ACTION"/> 
      <action android:name="NO_ACTION"/> 
      <action android:name="MAYBE_ACTION"/> 
     </intent-filter> 
    </receiver> 

Answer 3

here YES_ACTION必须是yourfullpackagename.YES

像

private static final String YES_ACTION = "com.example.packagename.YES"; 

同样可以使用NO_ACTION或MAYBE_ACTION

在广播接收器必须使用相同的YES_ACTION如上声明，

意味着广播接收器类，你可以检查定制的广播以下

public class NotificationReceiver extends BroadcastReceiver { 

private static final String YES_ACTION = "com.example.packagename.YES"; 
@Override 
public void onReceive(Context context, Intent intent) { 
    // TODO Auto-generated method stub 
    String action = intent.getAction(); 
    if(YES_ACTION.equals(action)) { 
     Toast.makeText(context, "CALLED", Toast.LENGTH_SHORT).show(); 
    } 
} 

}

注意：在YES_ACTION字符串中，您也可以使用其他字。

STEP_BY_STEP

步骤1

public void noto2() // paste in activity 
{ 
    Notification.Builder notif; 
    NotificationManager nm; 
    notif = new Notification.Builder(getApplicationContext()); 
    notif.setSmallIcon(R.drawable.back_dialog); 
    notif.setContentTitle(""); 
    Uri path = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION); 
    notif.setSound(path); 
    nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE); 

    Intent yesReceive = new Intent(); 
    yesReceive.setAction(AppConstant.YES_ACTION); 
    PendingIntent pendingIntentYes = PendingIntent.getBroadcast(this, 12345, yesReceive, PendingIntent.FLAG_UPDATE_CURRENT); 
    notif.addAction(R.drawable.back_dialog, "Yes", pendingIntentYes); 


    Intent yesReceive2 = new Intent(); 
    yesReceive2.setAction(AppConstant.STOP_ACTION); 
    PendingIntent pendingIntentYes2 = PendingIntent.getBroadcast(this, 12345, yesReceive2, PendingIntent.FLAG_UPDATE_CURRENT); 
    notif.addAction(R.drawable.back_dialog, "No", pendingIntentYes2); 



    nm.notify(10, notif.getNotification()); 
} 

步骤1.5

我创建全局类AppConstant

public class AppConstant 
    { 
    public static final String YES_ACTION = "YES_ACTION"; 
    public static final String STOP_ACTION = "STOP_ACTION"; 
    } 

步骤2：

public class NotificationReceiver extends BroadcastReceiver { 

@Override 
public void onReceive(Context context, Intent intent) { 
    // TODO Auto-generated method stub 
    String action = intent.getAction(); 
    if (AppConstant.YES_ACTION.equals(action)) { 
     Toast.makeText(context, "YES CALLED", Toast.LENGTH_SHORT).show(); 
    } 
    else if (AppConstant.STOP_ACTION.equals(action)) { 
     Toast.makeText(context, "STOP CALLED", Toast.LENGTH_SHORT).show(); 
    } 
} 

}

步骤3

<receiver android:name=".NotificationReceiver"> 
     <intent-filter> 
      <action android:name="YES_ACTION"/> 
      <action android:name="STOP_ACTION"/> 

     </intent-filter> 
    </receiver>
