java - 设置项目单击监听器事件没有受到影响吗？

Question

这是我以自定义格式显示 ListView 的代码。但我的要求是，当我单击 ListView 的任何项目时，需要显示其更多详细信息，但当我单击它时......它根本不显示生效我的意思是没有执行 setonitemclicklictener 事件....我请求请查看上面给出的我的代码....感谢大家

您需要添加

android:focusable="false"
android:focusableInTouchMode="false"

到您的row.xml的所有 View 。因为在自定义ListView中，因为它上面的 View 具有焦点，所以ListView无法使其焦点工作。
