android如何绘制一边的边框

Question

<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="#FFF" />
    <stroke 
    android:width="0.5dp" 
    android:color="#9d9d9d"
     /> 
    <padding 
    android:left="-2dp" 
    android:top="-2dp" 
    android:right="-2dp" 
    android:bottom="1dp" /> 
</shape>

padding试过0dp，-1dp,-2dp都不凑效，到底该怎样实现一边的边框呢？

Answer 1

如果题主只是想实现布局底部分割线的效果，那么在底部放入

<View
    android:layout_width="match_parent"
    android:layout_height="0.5dip"
    android:background="#9d9d9d" />

即可

如果题主一定要实现只绘制出一个边框的矩形，那么可以继承View自定义

Answer 2

好说，自定义view、attr.xml，在onDraw画出来，方向、颜色、宽窄，都可以自己控制。百度一下，不难。
