推荐答案

正如其他人所指出的，一个ninepatch将是理想在这种情况下的（并不会花费太多的内存）的。使用XML解决办法是不是最佳的。下面是一些你可以试试：

As others pointed out, a ninepatch would be ideal in this situation (and won't take much memory). Working around with XML is not optimal. Here is something you can try:

<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
    <item android:bottom="20dp">
        <shape android:shape="rectangle" >
            <size android:height="20dp" />
            <solid android:color="#ff0000" />
        </shape>
    </item>

    <item android:top="20dp">
        <shape android:shape="rectangle" >
            <size android:height="20dp" />
            <solid android:color="#0000ff" />
        </shape>
    </item>
</layer-list>

在这种情况下，你的观点被认为是beeing 40dp高的

这是一个图层列表，在不同颜色的两个街区。使用XML方法的问题是，不能块的高度调整到一个百分比（= 50％）。你必须使用一半的实际视图大小的DP。这意味着你必须每次调整此绘制你改变你观点的高度/布局。一个ninepatch会适应这种自动。

It's a layer list with two blocks in different colors. The problem with the XML approach is that you can't adjust the height of the blocks to a percentage (=50%). You have to use half of the actual view size in dp. Which means you have to adjust this drawable each time you change your view height/layout. A ninepatch would adjust to this automatically.
