提问by hap497
I have the following layout, which is 1 icon on the left and 2 text views (stack on top of each other) on the right. I would like to have the text1 vertically center in the panel and when I make the text2 Visible.GONE. Can you please tell me how can i do that?
我有以下布局，左侧有 1 个图标，右侧有 2 个文本视图（堆叠在一起）。我想让 text1 在面板中垂直居中，当我使 text2 Visible.GONE 时。你能告诉我我该怎么做吗？
<RelativeLayout android:id="@+id/panel"
android:layout_width="fill_parent"
android:layout_height="?android:attr/listPreferredItemHeight">
<ImageView
android:id="@+id/icon1"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_gravity="center_vertical"/>
<TextView android:id="@+id/text1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="@id/icon1"
android:textAppearance="?android:attr/textAppearanceSmall"
android:layout_gravity="center_vertical"/>
<TextView android:id="@+id/text2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="@id/icon1"
android:layout_below="@id/text1"
android:textAppearance="?android:attr/textAppearanceSmall"/>
</RelativeLayout>

All you have to do is, in your first example, to replace android:gravityon the ImageView by android:layout_gravity.
That's all :)
在第一个示例中，您所要做的就是android:gravity将 ImageView替换为android:layout_gravity。就这样 ：）

I'd change it to one relative layout with only three views inside. And you can use android:layout_centerHorizontal, android:layout_centerVerticalto align stuff as well.
我会将其更改为一种内部只有三个视图的相对布局。您也可以使用 android:layout_centerHorizontal, android:layout_centerVertical来对齐内容。
