Event OnClick for a button in a custom notification

I am writing code in my MyActivity.java class that extends android.app.Activity

It creates a custom notification, when user click on the button it sends a broadcast. There is a broadcast receiver that receives the broadcast.

private void createDownloadNotification() {
        Intent closeButton = new Intent("Download_Cancelled");
        closeButton.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);

        PendingIntent pendingSwitchIntent = PendingIntent.getBroadcast(this, 0, closeButton, 0);

        RemoteViews notificationView = new RemoteViews(getPackageName(), R.layout.widget_update_notification);

        NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

        NotificationCompat.Builder builder = new NotificationCompat.Builder(this).setSmallIcon(R.drawable.ic_launcher).setTicker("Ticker Text").setContent(notificationView);
        notificationView.setProgressBar(R.id.pb_progress, 100, 12, false);
        notificationView.setOnClickPendingIntent(R.id.btn_close, pendingSwitchIntent);

        notificationManager.notify(1, builder.build());

    }


public static class DownloadCancelReceiver extends BroadcastReceiver {

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

            System.out.println("Received Cancelled Event");
        }
    }

Register receiver in AndroidManifest.xml

<receiver android:name=".MainActivity$DownloadCancelReceiver" android:exported="false">
            <intent-filter>
                <action android:name="Download_Cancelled" />
            </intent-filter>
        </receiver>

Since it is inner class so have to use $ sign

Widget xml is here

<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:gravity="center"
    android:orientation="horizontal" >

    <Button
        android:id="@+id/btn_close"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Close Me" />

    <ProgressBar
        android:id="@+id/pb_progress"
        style="?android:attr/progressBarStyleHorizontal"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

</LinearLayout>

1. Create an xml layout file for your notification.

2. Create the notification using the Notification.Builder. After adding everything you want (icons, sounds, etc) do this:

   //R.layout.notification_layout is from step 1
   
   RemoteViews contentView=new RemoteViews(ctx.getPackageName(), R.layout.notification_layout);
   
   setListeners(contentView);//look at step 3
   
   notification.contentView = contentView;
   

3. Create a method setListeners. Inside this method you have to write this:

   //HelperActivity will be shown at step 4
   
   Intent radio=new Intent(ctx, packagename.youractivity.class);  
   radio.putExtra("AN_ACTION", "do");//if necessary
   
   PendingIntent pRadio = PendingIntent.getActivity(ctx, 0, radio, 0);
   //R.id.radio is a button from the layout which is created at step 2                  view.setOnClickPendingIntent(R.id.radio, pRadio); 
   
   //Follows exactly my code!
   Intent volume=new Intent(ctx, tsapalos11598712.bill3050.shortcuts.helper.HelperActivity.class);
   volume.putExtra("DO", "volume");
   
   //HERE is the whole trick. Look at pVolume. I used 1 instead of 0.
   PendingIntent pVolume = PendingIntent.getActivity(ctx, 1, volume, 0);
   view.setOnClickPendingIntent(R.id.volume, pVolume);
   

4. For my requirements I used a HelperActivity which responds to the intents. But for you I don't think it is necessary.

If you want the full source code you can browse it or download it from my git repo. The code is for personal use, so don't expect to read a gorgeous code with a lot of comments. https://github.com/BILLyTheLiTTle/AndroidProject_Shortcuts

ALL THE ABOVE, ANSWERS THE QUESTION OF CATCHING EVENT FROM DIFFERENT BUTTONS.

About canceling the notification I redirect you here (How to clear a notification in Android). Just remember to use the id you parsed at the notify method when you called the notification for fist time
