问题描述

所以这里的情况。我有多个 OnSwipe 和 OnClick 的运动布局设置,它们一起工作并创建一个流畅的动画。但是,当我将点击侦听器添加到运动布局的任何子项时,如下所示:

darkenForeground.setOnClickListener {
            Log.e("HI","");
        }

所有动作布局功能都停止工作,并且没有响应任何滑动或点击。甚至没有调用新添加的点击侦听器。如果您有任何想法为什么会发生这种情况,请告诉我。欢迎任何帮助。谢谢!

这是完整的布局

解决方案


从 XML 添加 clicklistener ..ie

  <FrameLayout
    android:id="@+id/darkenForeground"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:alpha="0.0"
    android:onClick="doSomething"
    android:background="@android:color/black"/>
