Android上的底栏

Question

如何在屏幕顶部占据大部分视图并且屏幕底部有一个位于其下方的底栏，而不直接设置顶视图的大小？

Answer 1

You can set the top View's android:layout_weight set to "1", then you can set your bottom View's height and the top View will take up all remaining space. For example:

<LinearLayout android:layout_width="fill_parent"
    android:layout_height="wrap_content" android:layout_weight="1" />
<LinearLayout android:layout_width="fill_parent"
    android:layout_height="25dip" />

(Of course, if there is content in the bottom View, you can just set the height to "wrap_content" and have it set its own size based on its contents.)
