如何防止触摸影响其父级的片段 activity
How to prevent touch from a fragment affecting its parent activity
我有一个从 activity 启动的片段。现在我注意到当一个空白区域被触摸时，父 activity 被触摸。只有按钮不受影响的区域。它的行为就好像它是透明的。
有什么办法可以避免吗？

是的，您必须让您的根视图可点击。只需设置 属性 clickable true 甚至不需要为此写空 OnClickListener。
android:clickable="true"
您的片段 xml 具有 ID 为 africell_cb_int 的根视图。使其可点击。
在 Fragment Xml 布局中为根标签添加 android:clickable="true"。
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clickable="true" />
