我在我的managerActivity中挂了listview的click事件，但是它不起作用.我还连接了我的自定义适配器.我在onclick事件中显示了一个测试吐司，但无法正常工作.请帮助
I have hookied on click event of my listview in my managerActivity but it is not working. I have also attached my custom adapter.I have displayed a test toast in the onclick event but it is not working. Kindly help
推荐答案
在适配器xml父级布局中粘贴以下行( android:descendantFocusability ="blocksDescendants" )，并粘贴 android:focusable适配器XML文件中的复选框或按钮中的="false" .
Paste the line (android:descendantFocusability="blocksDescendants") in you adapter xml parent layout and paste android:focusable="false" in the checkbox or button in the adapter xml file.
