It shows an error in a ImageView of my main class activity, but all the details are been correct in my coding side.

What's this error, how to over come this?

hi i have found my error, i have assigned linear layout in one of my xml file but i have mentioned it to be absolute layout in my class file.

ClassCastException in FirstImage class on line 106 ? It seems you try to cast something as an AbsoluteLayout in onCreate() method where it is not.

source :

I was getting this error Caused by: java.lang.ClassCastException: android.widget.LinearLayout cannot be cast to android.widget.TextView:

I changed

stringsAdapter = new ArrayAdapter<String>(this,R.layout.main,myStrings);

To

stringsAdapter = new ArrayAdapter<String>(this,android.R.layout.simple_expandable_list_item_1,myStrings);**

and problem is solved for me.
