Event OnClick for a button in a custom notification

Question

I have a custom notification with a button. To set the notification and use the event OnClick on my button I\'ve used this code:

//Notification and intent of         


        

Answer 1

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>

Answer 2

it seems that setOnClickPendingIntent doesn't work when used inside collections:

http://developer.android.com/reference/android/widget/RemoteViews.html#setOnClickPendingIntent(int,%20android.app.PendingIntent)

Try using setPendingIntentTemplate instead.

You need to create Service to detect on Click event: For example Create NotificationIntentService.class and put below code:

public class NotificationIntentService extends IntentService {

    /**
     * Creates an IntentService.  Invoked by your subclass's constructor.
     */
    public NotificationIntentService() {
        super("notificationIntentService");
    }

    @Override
    protected void onHandleIntent(Intent intent) {
        switch (intent.getAction()) {
            case "left":
                android.os.Handler leftHandler = new android.os.Handler(Looper.getMainLooper());
                leftHandler.post(new Runnable() {
                    @Override
                    public void run() {
                        Toast.makeText(getBaseContext(),
                                "You clicked the left button", Toast.LENGTH_LONG).show();
                    }
                });
                break;
            case "right":
                android.os.Handler rightHandler = new android.os.Handler(Looper.getMainLooper());
                rightHandler.post(new Runnable() {
                    @Override
                    public void run() {
                        Toast.makeText(getBaseContext(), "You clicked the right button", Toast.LENGTH_LONG).show();
                    }
                });
                break;
        }
    }
}

Add this metod to your activity:

private void sendNotification() {

    RemoteViews expandedView = new RemoteViews(getPackageName(), R.layout.view_expanded_notification);
    expandedView.setTextViewText(R.id.timestamp, DateUtils.formatDateTime(this, System.currentTimeMillis(), DateUtils.FORMAT_SHOW_TIME));
    expandedView.setTextViewText(R.id.notification_message, mEditText.getText());
    // adding action to left button
    Intent leftIntent = new Intent(this, NotificationIntentService.class);
    leftIntent.setAction("left");
    expandedView.setOnClickPendingIntent(R.id.left_button, PendingIntent.getService(this, 0, leftIntent, PendingIntent.FLAG_UPDATE_CURRENT));
    // adding action to right button
    Intent rightIntent = new Intent(this, NotificationIntentService.class);
    rightIntent.setAction("right");
    expandedView.setOnClickPendingIntent(R.id.right_button, PendingIntent.getService(this, 1, rightIntent, PendingIntent.FLAG_UPDATE_CURRENT));

    RemoteViews collapsedView = new RemoteViews(getPackageName(), R.layout.view_collapsed_notification);
    collapsedView.setTextViewText(R.id.timestamp, DateUtils.formatDateTime(this, System.currentTimeMillis(), DateUtils.FORMAT_SHOW_TIME));

    NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
            // these are the three things a NotificationCompat.Builder object requires at a minimum
            .setSmallIcon(R.drawable.ic_pawprint)
            .setContentTitle(NOTIFICATION_TITLE)
            .setContentText(CONTENT_TEXT)
            // notification will be dismissed when tapped
            .setAutoCancel(true)
            // tapping notification will open MainActivity
            .setContentIntent(PendingIntent.getActivity(this, 0, new Intent(this, MainActivity.class), 0))
            // setting the custom collapsed and expanded views
            .setCustomContentView(collapsedView)
            .setCustomBigContentView(expandedView)
            // setting style to DecoratedCustomViewStyle() is necessary for custom views to display
            .setStyle(new android.support.v7.app.NotificationCompat.DecoratedCustomViewStyle());

    // retrieves android.app.NotificationManager
    NotificationManager notificationManager = (android.app.NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    notificationManager.notify(0, builder.build());
}

it seems that setOnClickPendingIntent doesn't work when used inside collections.

So try setPendingIntentTemplate instead of setOnClickPendingIntent. for more information bellow android developer link...

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
