  • 44.Android之Shape设置虚线、圆角和渐变学习

    Shape在Android中设定各种形状,今天记录下,由于比较简单直接贴代码。

    Shape子属性简单说明一下:   
    gradient -- 对应颜色渐变。 startcolor、endcolor就不多说了。 android:angle是指从哪个角度开始变.
    solid -- 填充。
    stroke -- 描边。
    corners -- 圆角。
    padding -- 定义内容离边界的距离。 与android:padding_left、android:padding_right这些是一个道理.
