Android. Handling button clicks in the statusbar

How can I handle clicking on the "apps" button?

Custom_notification.xml:

<Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="apps"
    android:onClick="notification_apps"
    android:id="@+id/notification_apps"/>

Notification.java:

public class Notification {

private static Context context;

public static void setContext(Context _context) {
    Notification.context = _context;
}

@TargetApi(Build.VERSION_CODES.JELLY_BEAN)
public static void runNotification(){
    RemoteViews contentView = new RemoteViews(context.getPackageName(), R.layout.custom_notification);
    //contentView.setRemoteAdapter(R.id.notification_apps, new Intent(context, HomeActivity.class));

    // Create an Intent to launch ExampleActivity
    Intent intent = new Intent(context, HomeActivity.class);
    PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);

    // Get the layout for the App Widget and attach an on-click listener
    contentView.setOnClickPendingIntent(R.id.notification_apps, pendingIntent);

    NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context);

    mBuilder.setOngoing(true);
    mBuilder.setSmallIcon(R.drawable.home);
    mBuilder.setContent(contentView);

    Intent resultIntent = new Intent(context, HomeActivity.class);
    TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
    stackBuilder.addParentStack(HomeActivity.class);


    stackBuilder.addNextIntent(resultIntent);
    PendingIntent resultPendingIntent = stackBuilder.getPendingIntent(0,PendingIntent.FLAG_UPDATE_CURRENT);
    mBuilder.setContentIntent(resultPendingIntent);

    NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
    mNotificationManager.notify(0, mBuilder.build());
}
}

HomeActivity.java:

public class HomeActivity extends Activity{
    //....
    public void notification_apps(View view) {
        Intent i = new Intent(HomeActivity.this, AppsListActivity.class);
        startActivity(i);
    }
}
