set onclicklistener for button inside customlistview android

Replace this

holder.qua.setText(num);

by

holder.qua.setText(String.valueOf(num));

coz you have this

int num=Integer.parseInt(vall); // num is an int value
num=num+1;

public final void setText (int resid)

In your case it looks for a resource with the id. If not found you get ResourceNotFoundException.

What you need

public final void setText (CharSequence text) which takes CharSequence as param.

So use String.valueOf(num)
