当我在“ADD ITEM BELOW”评论下方添加项目时,如下所示,我的onItemLongClick
和ListItemClick
无效。但是,一旦我删除了“ADD ITEM BELOW”下面的项目,它就会起作用。怎么了?

如果你想使onItemClick工作添加
机器人:descendantFocusability =&#34; blocksDescendants&#34;
到父布局之类的东西: -
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/caldroid_transparent"
android:orientation="vertical"
android:descendantFocusability="blocksDescendants">
</LinearLayout>
当你阻止后代时,你就无法获得onClick事件 ListView行中的按钮。基本上你可以在任一行上获得事件 或按钮连续。

尝试更改:
@Override
public void onListItemClick(ListView l, View v, int position, long id) {
super.onListItemClick(l, v, position, id);
// remove code for simplicity
}
到
getListView().setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public boolean onItemClick(AdapterView<?> arg0, View view, int position, long id) {
// whatever code would have been above put in here
}
