我在搜索活动中有一个gridview，我想为它添加监听器。我试图为网格视图设置Onitem click监听器，但它不起作用。我试过在网格适配器类中添加监听器，但我没有得到正确的值。我试过以下
1.setfocusable= true
set Touchfocusable =true in button
2.I have set layout android:descendantFocusability="blocksDescendants" in RelativeLayout.
I don't know where I have done the mistake, anyone help me out with this.
