Android Adding Button Click Action In Notification Bar

Hello,

Recently in one of my project we have a requirement to add button in notification area and do some actions when button is clicked. So here in this blog I am going to explain how to do this.

First of all Add following XML file in your layout and name it as custom_notification. This will have definition for button we are going to add in notification bar.

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="match_parent"

    android:layout_height="fill_parent"

    android:gravity="center_vertical"

    android:orientation="vertical" >

<Button 

        android:id="@+id/myButton" 

        android:layout_width="wrap_content" 

        android:layout_height="40sp" 

        android:layout_weight="1" 

        android:text="Click Me"

        android:textColor="#000000"

        android:textSize="10sp">

    </Button>

</LinearLayout>

Now in your MainActivity add following function and call it in onCreate method to create notification with button.

public void createNotificationInNotificationBar(){

int icon = R.drawable.ic_launcher;

long when = System.currentTimeMillis();

Notification notification = new Notification(icon, "Click Me To Do Some Action", when);

NotificationManager mNotificationManager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);

contentView = new RemoteViews(getPackageName(), R.layout.custom_notification);

notification.contentView = contentView;

Intent notificationIntent = new Intent(this, MainActivity.class);

PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);

notification.contentIntent = contentIntent;

notification.flags |= Notification.FLAG_NO_CLEAR; //Do not clear the notification

}

Above code will create notification with button. User will not be able to clear this notification. Now we will add click action handler to button. Add following lines at end of above function.

Intent myIntent = new Intent("button_clicked");

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

contentView.setOnClickPendingIntent(R.id. myButton, 

                pendingSwitchIntent);

Now add following code to your Manifest.xml file.

This will create receiver and action. Now add receiver to your main activity.

public static class RecordShareReceiver extends BroadcastReceiver {

@Override

public void onReceive(Context context, Intent intent) {

Intent myIntent = new Intent(context.getApplicationContext(), ButtonClickActivity.class);

myIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

context.startActivity(myIntent);

}

}

This will start ButtonClickActivity. 

public class ButtonClickActivity extends Activity{

@Override

public void onCreate(Bundle savedInstanceState)

{

super.onCreate(savedInstanceState);

//Do your actions here

finish();

}

}

As you can see in above in onCreate method you can do the actions as per your requirement. Once the action is done we finish activity.

Add following code to your android manifest for activity.

android:label="@string/app_name" 

android:launchMode="singleTask" 

android:name=". ButtonClickActivity" 

android:screenOrientation="portrait" 

android:theme="@android:style/Theme.Translucent.NoTitleBar" />

As you can see above we set theme as Translucent theme so activity will not be visible. It will just start do the action and gets finished.
