Dynamically set the GridView height, fixed column, for highly adaptive

Dynamically sets the height of the GridView, fixed column, and sets the height according to the item number in the GridView:

Call the following methods:

 public static void Setlistviewheightbasedonchildren (GridView listview) {//Get ListView Adapter ListAdapter List        Adapter = Listview.getadapter ();        if (ListAdapter = = null) {return;        }//fixed column width, how many columns int col = 4;//Listview.getnumcolumns ();        int totalheight = 0; I add 4 each time, equivalent to Listadapter.getcount () is less than or equal to 4 o'clock cycles once, calculates the height of the item once,//Listadapter.getcount () is less than or equal to 8 o'clock calculates two times the height of the add for (int i = 0; I < Listadapter.getcount ();            i + = col) {//Get ListView for each item View ListItem = Listadapter.getview (i, NULL, ListView);            Listitem.measure (0, 0);        Gets the height of item and Totalheight + = Listitem.getmeasuredheight ();        }//Get the layout parameters of the ListView viewgroup.layoutparams params = Listview.getlayoutparams ();        Set height params.height = totalheight;        Set the margin ((marginlayoutparams) params. SetMargins (10, 10, 10, 10);    Set the parameter listview.setlayoutparams (params);} 

After calling this method, you need to invoke the Notifydatasetchanged () method to implement the interface refresh
