java - OnItemClickListener 无法与 AutoCompleteTextView 一起使用

Question

我使用了带有 customLayout 和 Adapter 的 autoCompleteTextView，但问题是当我们单击建议中的某个项目时，该项目值既不会填充到 autoCompleteTextView 中，也不会触发 OnItemClickListener。

代码使用 autoCompleteTextView 中输入的文本过滤建议，但 onClick 事件没有任何反应。

下面是我的代码

TeamSuggestionAdapter.java 文件

Answer 1

将 android:descendantFocusability="blocksDescendants" 添加到 add_match_suggestions_layout.xml 中的 LinearLayout 并删除了focusable 和 clickable 由此，解决了问题。
