如何防止影响其父活动的片段的触摸

Question

我有一个从活动中启动的片段。现在我注意到，当触摸空白区域时，会触摸父活动。只有有按钮不受影响的区域。它就像是透明的一样。

有没有办法防止这种情况？

是的，您必须使您的根视图可以点击。只需设置属性clickable true即使不需要为此写空OnClickListener。

android:clickable="true"

您的Fragment xml具有标识为africell_cb_int的根视图。点击它。

Answer 2

在Fragment Xml布局中为根标记添加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" />
