我在这里搜索了很多问题并且已经实现了我从这里得到的每个答案，但没有人解决这个问题。我的自定义列表视图中有两个按钮，我想点击它们。这是我的自定义适配器和xml代码。

谁能告诉我哪里弄错了？我的工作即将完成，应用程序几乎准备就绪，但我陷入了这个问题。我将感谢任何类型的建议或帮助。

我不确定，但请尝试holder.edit.setOnClickListener（new View.OnClickListener（）） 而不是holder.edit.setOnClickListener（new OnClickListener（））。
答案 1 :(得分：1)
试试这个
将此cartlist_row.xml添加到父Linearlayout
android:clickable="false"
android:descendantFocusability="blocksDescendants"
android:focusable="false"
android:focusableInTouchMode="false"
为Button添加此
android:clickable="false"
android:focusable="false"
android:focusableInTouchMode="false"
和AlertDialog.Builder构建器无法正常工作，你从未使用过show（）..请交叉检查..使用
AlertDialog alert = builder.create(); alert.show();
