here mention xml file also.

it hard find out went wrong
you have , customadapter. have button inside activity_row2 inflated row items.
dataadapter = new simplecursoradapter( this, r.layout.activity_row2, projectscursor, from, to, 0); you have defined customadapter never use it.
string[] = new string[]{ginfydbadapter.category_column_title,ginfydbadapter.category_column_content,ginfydbadapter.category_column_count}; // , array of fields want bind fields (in case text1) int[] = new int[]{r.id.text2,r.id.text1,r.id.count}; dataadapter = new customadapter (yourprayeractivity .this, r.layout.activity_row2, projectscursor, from, to); also change customadapter below
class customadapter extends simplecursoradapter { private layoutinflater minflater; @suppresswarnings("deprecation") public customadapter(context context, int layout, cursor c, string[] from, int[] to) { super(context, layout, c, from, to); minflater= layoutinflater.from(context); toast.maketext(yourprayeractivity.this, "text", 1000).show(); // todo auto-generated constructor stub } @override public void bindview(view view, context context, final cursor cursor){ int row_id = cursor.getcolumnindex("_id"); //your row id (might need replace) textview tv = (textview) view.findviewbyid(r.id.text1); final textview tv1 = (textview) view.findviewbyid(r.id.text2); int col1 = cursor.getcolumnindex("title"); string title = cursor.getstring(col1 ); int col2 = cursor.getcolumnindex("content"); final string content = cursor.getstring(col2 ); tv.settext( title); tv1.settext( content); button button = (button) view.findviewbyid(r.id.buttonsms); button.setonclicklistener(new onclicklistener(){ @override public void onclick(view v){ log.i("....................",""+cursor.getcount()); toast.maketext(yourprayeractivity.this, "text",400000).show(); } }); } @override public view newview(context context, cursor cursor, viewgroup parent){ layoutinflater inflater = layoutinflater.from(context); view v = inflater.inflate(r.layout.activity_row2, parent, false); bindview(v,context,cursor); return v; } }
