Android rewrite ListView using Addheaderview and Addfooterview considerations

1. Add Addheaderview or Addfooterview

When adding Headerview or Footerview to the ListView, you can choose Addheaderview (Headview) or Addheaderview (Headview, NULL, FALSE), Note that the third parameter of the latter, Boolean isselectable, sets the Onitemclick event in the ListView and needs to set the isselectable to false to ensure that the Click App appears abnormal

2. Item contains button or click Control

If the ListView item has a control such as a button, the control masks the Onitemclick event of the ListView and can set android:descendantfocusability= in the item's XML file " Afterdescendants "or set Setdescendantfocusability (viewgroup.focus_block_descendants) in the program to block child controls from grabbing the focus, Ensure that both the item and child controls are executed properly.
