How to make my widget clickable?

My widget is just a battery monitor. But i want to open a full screen activity with more info.

here is the AndroidBatteryWidgetProvider.java:

package cogiloo.widget;

import android.app.PendingIntent;
import android.appwidget.AppWidgetManager;
import android.appwidget.AppWidgetProvider;
import android.content.ComponentName;
import android.content.Context;
import android.content.Intent;
import android.widget.RemoteViews;

public class AndroidBatteryWidgetProvider extends AppWidgetProvider {


    @Override
    public void onUpdate(Context context, AppWidgetManager appWidgetManager,
            int[] appWidgetIds) {
        // TODO Auto-generated method stub
        updateWidget(context);
        context.startService(new Intent(context, MyBatteryReceiver.class));     

    }

    public void updateWidget(Context context){
        RemoteViews updateViews = new RemoteViews(context.getPackageName(), R.layout.androidbatterywidget_layout);
        updateViews.setTextViewText(R.id.level, "waiting!");

        ComponentName myComponentName = new ComponentName(context, AndroidBatteryWidgetProvider.class);
        AppWidgetManager manager = AppWidgetManager.getInstance(context);
        manager.updateAppWidget(myComponentName, updateViews);
    }

}

Modify updateWidget() to create and assign a new PendingIntent.

public void updateWidget(Context context){
    RemoteViews updateViews = new RemoteViews(context.getPackageName(), R.layout.androidbatterywidget_layout);
    Intent intent = new Intent(context, Battery.class);
    PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
    updateViews.setOnClickPendingIntent(R.id.widget, pendingIntent);
    ...
}

To make a Widget clickable you need to call setOnClickPendingIntent on the widget's Remote View, passing in the resource identifier of the View you want to make clickable, and the Pending Intent you want it to fire.

In your example it would look something like this:

Intent intent = new Intent(context, Battery.class);
PendingIntent pi = PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

updateViews.setOnClickPendingIntent(R.id.level, pi);

ok Before

 manager.updateAppWidget(myComponentName, updateViews);

you have to define an intent that is triggered when you click for example an imagen in your Widget (R.id.imagetoClick)

Intent defineIntent = new Intent(); 
    defineIntent.setClassName("cogiloo.widget","cogiloo.widget.ActivitytoShow");
PendingIntent pendingIntent = PendingIntent.getActivity(context,
0 /* no requestCode */, defineIntent, 0 /* no flags */);
    updateViews.setOnClickPendingIntent(R.id.imagetoClick, pendingIntent);
