我想在底部添加RecyclerView到我的布局,但它处于错误的位置。
现在我有:
现在RecyclerView太落了,减少了一半的RecyclerView。我只想在我的布局底部使用RecyclerView,但我无法做到。
这是我的布局代码:
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"

android:layout_height="match_parent"
tools:context="showresultactivity.SlideTabsActivity">

<FrameLayout

</android.support.constraint.ConstraintLayout>

修改 我忘了我还有底部导航,回收器应该在底部地图但在底部导航上方。 底部导航布局:

答案 0 :(得分:0)
将此行添加到framelayout将有助于您实现这种定位:
app:layout_constraintBottom_toBottomOf="parent"
还要记住将框架布局的高度设置为: wrap content
。上面这一行的目的是将框架布局固定/固定到约束布局的底部;任何最终的扩张都将是向上的。因此,框架布局的内容永远不会重叠。如果需要额外的空间,框架布局将向上投影,同时仍固定在约束布局的底部。
您可以在Constraint布局上查看更多XML属性的参考:https://developer.android.com/reference/android/support/constraint/ConstraintLayout.html
PS:
您可以删除框架布局的android:layout_alignParentBottom="true"
部分;它不再是必要的了
