i used android intent pass specific value of button activity. issue in code button , using wrong key value passing in activity.:
imagebutton ib_s = (imagebutton) findviewbyid(r.id.ib_s); ib_s.setonclicklistener(new view.onclicklistener() { @override public void onclick(view v) { //startactivity( new intent( alphabat_pics.this, alphabet_meaning.class )); alphabet_meaning.putextra("ib", string_array[18]); startactivity(alphabet_meaning); } });
