推荐答案

我已经解决了它自己。 所有你需要做的就是定义一个适当的参数的查看和使用颜色填充背景。您可能需要使用嵌套的线性布局正确定位就行了。

I have solved it myself. All you need to do is define a View with appropriate parameters and fill the background with color. You may want to use nested linear layouts for positioning the line correctly.

<View 
      android:id="@+id/View01"
      android:layout_width="2dip"
      android:layout_height="500dip"
      android:background="#2B497B"
/>
