Question

我必须在点击其他视图时实现扩展/折叠（显示/隐藏）特定视图。最终让它工作但是有一个小问题。
我有一个有两个孩子的相对布局：第一个是textview，第二个是线性布局在textview的click事件中，我设置了以下线性布局的可见性（VISIBLE或GONE）现在的问题是，在线性布局可见后，它会以某种方式设法隐藏文本视图我尝试了textview.bringToFront()，但它只是使textview与linearlayout的第一行重叠，即textview位于线性布局内容之上。
我尝试将textview放在线性布局中，但没有区别我尝试将线性布局设置为BELOW。一切都是徒劳的..
我知道textview存在，因为当我点击第一行（与textview重叠）时，click事件被触发了。
我想要的是，无论我的textview应该是什么，并且如果可见，线性布局必须在textview下面的位置。

Answer 1

你可以将LinearLayout存储为实例变量，只需调用layout.setvisibility（View.GONE）;在你的onClick方法中。怀疑任何其他解决方案，除非你想保存父（你的两个视图附加到的布局）并在onClick内执行findViewById或调用getChildAt（1）orso

Answer 2

有一个解决方案..我尝试设置边距..而且一切都很好.. te句柄和内容都可见而不隐藏任何其他视图..
