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.

运行我们发现虚线1和虚线2没有看到虚线效果,这是因为从android3.0开始安卓关闭了硬件加速功能,所以就不能显示了,解决方法在 AndroidManifest.xml,或者是在activity中把硬件加速的功能关掉就可以了。我采用第一种方法改下AndroidMainfest.xml, 设置下android:hardwareAccelerated="false",如图:
最后运行效果:
