The method of ScrollView nested GridView in the development of Android programming _android

This article illustrates the ScrollView nested GridView method of Android programming development. Share to everyone for your reference, specific as follows:

A few days ago in the development of the need to scrollview nested gridview, because these two controls are brought by the scroll bar, when they encounter together will be a problem, that the GridView will not show the whole, in order to solve this problem to find more than n data, A Google official reply unexpectedly is the GridView does not need to scrollview, that bullish, ah, but I have to use the swollen do it?! and continue to check, God horse rewrite the control rewrite class, that code a lump of wood has!!! Finally, the inspiration is finally realized by someone with a very vague hint.

The first is the layout

<ScrollView> ...
  <LinearLayout>
  </LinearLayout> ...
</ScrollView>

All we have to do is customize a GridView control and insert it into the middle of the linearlayout.

public class MyGridView extends gridview{
the public mygridview (context context, AttributeSet Attrs) {
 super ( context, attrs);
}
Public MyGridView {
 super (context);
}
Public MyGridView (context, AttributeSet attrs, int defstyle) {
 Super (context, attrs, Defstyle);
}
@Override public
void onmeasure (int widthmeasurespec, int heightmeasurespec) {
  int expandspec = Measurespec.makemeasurespec (Integer.max_value >> 2,
   measurespec.at_most);
  Super.onmeasure (Widthmeasurespec, Expandspec);
}

This custom control only rewrites the GridView Onmeasure method so that it does not appear scrollbars, ScrollView nesting listview is the same truth, no longer tired of

I hope this article will help you with the Android program.
