ArrayAdapter<String>(this,android.R.layout.simple_list_item_1 , lv_arr));
lv1.setTextFilterEnabled(true);
lv1.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int position, long
arg3) {
// TODO Auto-generated method stub
AlertDialog.Builder adb=new
AlertDialog.Builder(ListviewOnclickExample.this);
