Android: put element below another element and align at bottom of screen
提问by liarspocker
I am trying to define a layout where an ImageViewis aligned at the bottom of the screen and also under a GridView, to avoid overlapping.
我试图定义一个布局，其中 anImageView在屏幕底部对齐，也在 a 下对齐GridView，以避免重叠。
This however results in the ImageViewbeing set just under the GridViewbut not aligned with the bottom of the screen.
然而，这会导致ImageView设置GridView在屏幕下方但未与屏幕底部对齐。
Can this be solved using a different kind of Layout?
这可以使用不同类型的布局来解决吗？

This is how I would do that:
这就是我将如何做到的：
1 - Put the ImageView on the Bottom
2 - Put the GridView ABOVE it.
1 - 将 ImageView 放在底部
2 - 将 GridView 放在它上面。
<!-- First anchor this View to the bottom -->
<ImageView
android:id="@+id/gs_bottom_logo"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:adjustViewBounds="true"
android:maxWidth="200dp"
android:paddingLeft="20dp"
android:paddingRight="20dp"
/>
<!-- Then put this View ABOVE the ImageView -->
<GridView
android:id="@+id/gs_grid_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@id/gs_top_text_container"
android:layout_above="@id/gs_bottom_logo"
android:descendantFocusability="blocksDescendants"
android:horizontalSpacing="2dp"
android:verticalSpacing="2dp"
android:numColumns="3"
android:gravity="center"
android:paddingBottom="10dp"
android:paddingTop="10dp"
/>
This way I used the relativityof elements in a RelativeLayout
这样，我用相对论元素的一个RelativeLayout的

Just for fun... I optimized your WHOLE LAYOUT.
Please note how the same designis achieved by using many layouts less.
只是为了好玩……我优化了你的整体布局。
请注意如何通过减少使用许多布局来实现相同的设计。

And this is what I got in the Graphical Editor (I put some images I had and some texts to identify the TextViews):
这就是我在图形编辑器中得到的（我放了一些我拥有的图像和一些文本来识别 TextViews）：

Solved it by putting the ImageView in a RelativeLayout, setting the layout_belowitem in the RelativeLayout and the alignParentBottomitem of ImageView:
通过将ImageView 放在 RelativeLayout 中、在 RelativeLayout中设置layout_below项和alignParentBottomImageView 项来解决它：
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="@id/gs_grid_view">
<ImageView
android:id="@+id/gs_bottom_logo"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:adjustViewBounds="true"
android:maxWidth="200dp"
android:paddingLeft="20dp"
android:paddingRight="20dp"/>
</RelativeLayout>
