I know that you can launch Activities from the action buttons using PendingIntents. How do you make it so that the a method gets called when the user clicks the notification action button?
public static void createNotif(Context context){
...
drivingNotifBldr = (NotificationCompat.Builder) new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.steeringwheel)
.setContentTitle("NoTextZone")
.setContentText("Driving mode it ON!")
//Using this action button I would like to call logTest
.addAction(R.drawable.smallmanwalking, "Turn OFF driving mode", null)
.setOngoing(true);
...
}
public static void logTest(){
Log.d("Action Button", "Action Button Worked!");
}

You can't directly call methods when you click action buttons.
You have to use PendingIntent with BroadcastReceiver or Service to perform this. Here is an example of PendingIntent with BroadcastReciever.
First lets build a Notification
public static void createNotif(Context context){
...
//This is the intent of PendingIntent
Intent intentAction = new Intent(context,ActionReceiver.class);
//This is optional if you have more than one buttons and want to differentiate between two
intentAction.putExtra("action","actionName");
pIntentlogin = PendingIntent.getBroadcast(context,1,intentAction,PendingIntent.FLAG_UPDATE_CURRENT);
drivingNotifBldr = (NotificationCompat.Builder) new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.steeringwheel)
.setContentTitle("NoTextZone")
.setContentText("Driving mode it ON!")
//Using this action button I would like to call logTest
.addAction(R.drawable.smallmanwalking, "Turn OFF driving mode", pIntentlogin)
.setOngoing(true);
...
}
Now the receiver which will receive this Intent
public class ActionReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
//Toast.makeText(context,"recieved",Toast.LENGTH_SHORT).show();
String action=intent.getStringExtra("action");
if(action.equals("action1")){
performAction1();
}
else if(action.equals("action2")){
performAction2();
}
//This is used to close the notification tray
Intent it = new Intent(Intent.ACTION_CLOSE_SYSTEM_DIALOGS);
context.sendBroadcast(it);
}
public void performAction1(){
}
public void performAction2(){
}
}
Declare Broadcast Receiver in Manifest
<receiver android:name=".ActionReceiver" />
Hope it helps.
