From first activity, I have to inflate the second.xml or third.xml
depending on the grid item chosen from home.xml..
second.xml and third.xml have their corresponding
public class second_xml extends ViewGroup implements View.OnClickListener
{
@Override
public void onClick(View arg0) {
//do something
}
}
public class third_xml extends ViewGroup implements View.OnClickListener
{
}
What the proper way of inflating this xml view, on the first menu.. And
linking the click and touch events of this layout into second_xml class..
I dont know,how I will transfer all click events of second.xml into
second_xml class Or what is the proper way of inflating this layout and
linking events with their corresponding class
