onClickListener 不适用于扩展 PagerAdapter 的活动适配器类中的 ImageView

Question

onclicklistner 在扩展 PagerAdapter 的 ActivityAdapterClass 中不工作。任何人都可以帮助我我做错了什么，因为我无法指出错误。我的代码如下：-

row_story_details.xml

Answer 1

尝试将 descendantFocusability 属性添加到您的根 RelativeLayout:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ffffff"
android:descendantFocusability="blocksDescendants">

Answer 2

在您拍摄的所有 ImageView 中添加这些行：

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

并在 OnClick 中实现 event.This 应该可以工作，因为我在我的一个应用程序中遇到了同样的问题，这解决了我的问题
