Thanks guys for attention.
public void onRadioButtonClick(View v) {
RadioButton rb = (RadioButton) v;
Toast.makeText(getApplicationContext(),
rb.getText(),Toast.LENGTH_SHORT).show();
View Rg = (View) rb.getParent();
View LLayout = (View) Rg.getParent();
TextView txtLvId = (TextView) LLayout.findViewById(R.id.ins_itemid);
String LvID = txtLvId.getText().toString();
Toast.makeText(getApplicationContext(), LvID, Toast.LENGTH_LONG).show();
}
I was making project for my collage attendence and i had faced same trouble as you , I solved these problem by just putting these code in my activity code is :-
upload.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
int child=listView.getChildCount();
for(int i=0;i<child;i++) {
View rgg=listView.getChildAt(i);
radioGroup = (RadioGroup) rgg.findViewById(R.id.radio);
int selectedId=radioGroup.getCheckedRadioButtonId();
radioButton = (RadioButton) rgg.findViewById(selectedId);
}
}
});
