android - TextView 阻止单击 ListView

Question

我有一个 ListView 和一个创建项目列表的自定义 ArrayAdapter。我正在努力做到这一点，因此单击列表项上的任意位置都会执行某些操作。然而，唯一可点击的区域在文本区域之外。

红色的左、右、上之外是可点击的。

我认为您需要从 listView 中删除 android:descendantFocusability="blocksDescendants"。如果我理解正确，我相信它会阻止 textview 获得焦点/点击并将其传递给父级。也许尝试将其设置为“beforeDescendants”。

如果找不到适合您的解决方案，一种解决方法是将 OnClickListener 设置为执行与 ListView 相同功能的 TextView 。
