为什么看不见的LinearLayout占用空间? [英] Why does a LinearLayout which is invisible take up space?

问题描述

我有以下LinearLayout ...

I've got the following LinearLayout...

<LinearLayout android:id="@+id/linearLayout3" android:visibility="invisible" android:layout_width="wrap_content" android:layout_height="wrap_content">
<TextView android:layout_height="wrap_content" android:layout_width="wrap_content" android:id="@+id/S"></TextView>
<TextView android:layout_height="wrap_content" android:layout_width="wrap_content" android:id="@+id/b"></TextView>
<TextView android:layout_height="wrap_content" android:layout_width="wrap_content" android:id="@+id/Ar"></TextView>
</LinearLayout>

我已将visible设置为invisible，但是LinearLayout仍然占用空间，导致布局中其他两个linearlayout之间出现填充，为什么?如何使其不占用空间?

I've set the visibly to invisible but the LinearLayout still takes up space causing padding between two other linearlayouts in the layout, why? How do I make it take up no space?

推荐答案

因为如果您希望视图不占用空间，则必须将可见性设置为gone.

Because you have to set the visibility to gone if you want that the view takes no space.
