Android widget onclick listener for several buttons

It is possible to make an onClick event for Views in Widgets. You can create as many onClick events as you want.

On top of your Widget class, create a static variable, which will be your onClick name tag:

private static final String MyOnClick = "myOnClickTag";

Define a helper method to automate the creation of each PendingIntent:

protected PendingIntent getPendingSelfIntent(Context context, String action) {
    Intent intent = new Intent(context, getClass());
    intent.setAction(action);
    return PendingIntent.getBroadcast(context, 0, intent, 0);
}

Set this onClick tag to your view as below:

    remoteViews.setOnClickPendingIntent(R.id.button, 
                      getPendingSelfIntent(context, MyOnClick));

create an onReceive method in your Widget class and set this onClick event inside it:

public void onReceive(Context context, Intent intent) {

    if (MyOnClick.equals(intent.getAction())){
        //your onClick action is here
    }
};

Whenever the view that you set the tag is pressed, onReceive will capture that and will do the action just the same as our everyday, standard onClick event.

Edit: According to your answer, can you replace your onUpdate content with following lines and try again:

    RemoteViews remoteViews = new RemoteViews(context.getPackageName(),R.layout.widget_det);
    thisWidget = new ComponentName(context, MyWidgetProvider.class);    
    remoteViews.setOnClickPendingIntent(R.id.widget_button_stayarm, getPendingSelfIntent(context, MyOnClick1));
    remoteViews.setOnClickPendingIntent(R.id.widget_button_awayarm, getPendingSelfIntent(context, MyOnClick2));
    remoteViews.setOnClickPendingIntent(R.id.widget_button_dissarm, getPendingSelfIntent(context, MyOnClick3));
    remoteViews.setTextViewText(R.id.widget_textview_gpscoords, "gps cords");
    appWidgetManager.updateAppWidget(thisWidget, remoteViews);

just call the super in your onReceive method

@Override
public void onReceive(Context context, Intent intent) {
    super.onReceive(context, intent);//add this line
    if (MyOnClick1.equals(intent.getAction())) {
        // your onClick action is here
        Toast.makeText(context, "Button1", Toast.LENGTH_SHORT).show();
        Log.w("Widget", "Clicked button1");
    } else if (MyOnClick2.equals(intent.getAction())) {
        Toast.makeText(context, "Button2", Toast.LENGTH_SHORT).show();
        Log.w("Widget", "Clicked button2");
    } else if (MyOnClick3.equals(intent.getAction())) {
        Toast.makeText(context, "Button3", Toast.LENGTH_SHORT).show();
        Log.w("Widget", "Clicked button3");
    }
}
