您需要一个定制的适配器。

覆盖的方法

  ListAdapter.isEnabled（INT位置）
 

和覆盖ListAdapter.areAllitemsEnabled（）返回false。

完全关闭点击，以及选择的图形在GridView控件的用户界面。

            }
            });

            alert.show();
        }
    });

解决方案

You need a custom adapter.

Override the methods

ListAdapter.isEnabled(int position)

and override ListAdapter.areAllitemsEnabled() to return false.

Completely disables clicking, as well as selection graphics in the UI for GridView.
