This is because of object reuse in your list view.
You can manage separate ArrayList or HashMap to maintain your likes.
And based on that you should update in your getView like this,
if([already selected]) {
viewHolder.likebtn.setBackground([your selected drawable]);
} else {
viewHolder.likebtn.setBackground([your non selected drawable]);
}

fix listview data disappear when activity restarted in android

I wrote an android app and it simply displays a list view.
and everything works fine except one.
I installed my app on my tablet and when i run the app, that problem occurs.
==>. that is . . .
When I press power button to turn off screen and press power button again to turn screen on, the whole list view data disappears.
I think this is some problem with activity lifecycle, but I can't deal with this..
Please help me..

wrong item is being selected in listview when selecting checkbox

**
When i select the items which are at the bottom of the listview,they wont get selected,
rather only first four items in the list is being selected.its because the items are out of view.
what to do to get these items in view ??sometimes the item gets randomly selected.
Please help me.
thank you

You already have check box reference stored in the holder, I wonder why you are initializing it again.
holder.checkBox.setChecked(buttonView.isChecked() ? true : false);
Checked state will be changed when the user clicks the checkbox, so no need to change the checked state again.
Try the following code
----

holder.checkBox.setTag(position);
holder.checkBox.setChecked(searchArrayList.get(position).isChecked());
holder.checkBox..setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
