Read android:src in ImageView in the Widget.xml file

Question

I have a Widget that toggles between two images, the widget changes each time a user clicks on it So I define a layout for this widget as follows

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <ImageView
        android:id="@+id/parrotstate"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:clickable="true"
        android:src="@drawable/widget_awake" />

</RelativeLayout>

In the AppWidgetProvide class, I need to read the attribute android:src to know which image is set. Normally I use findViewById in the Activity class but here it is AppWidgetProvide class

probably this question is duplicated try with this post http://stackoverflow.com/questions/4666687/how-to-find-view-id-in-appwidgetprovider — ƒernando Valle, Mar 11 '13 at 11:56
I know I should use RemoteViews but it does not have a function to access the imageView — yasserbn, Mar 11 '13 at 11:58
why dont get the count with a boolean? is not difficult the implementation. I will post you an example if you want. — ƒernando Valle, Mar 11 '13 at 12:00
This boolean maybe killed if declared inside onReceive() of the AppWidgetProvider(). Where should I define it to be saved all the time and read it when clicking on the Widget — yasserbn, Mar 11 '13 at 12:04

probably this question is duplicated try with this post: How to find view id in appwidgetprovider?

With the constructor you can get the Remoteview:

RemoteViews(String packageName, int layoutId)
//Create a new RemoteViews object that will display the views contained in the specified layout file.

apply returns the view

apply(Context context, ViewGroup parent)
//Inflates the view hierarchy represented by this object and applies all of the actions.

I do not understand what is ViewGroup in my case. I have an ImageView inside a RelativeLayout. – yasserbn Mar 11 '13 at 12:11
ViewGroup is where do you want to set your View, example a Layout. – ƒernando Valle Mar 11 '13 at 12:53
