Android2.1加载9Patch图片运行后报错


今天遇到一个很无语的问题，竟然是9Patch图片上多加了光晕效果。

因为需要自定义Button，所以请用了9Patch图片，而且图片上面还有一点光晕效果，同样也被拉伸了，在2.2的系统上面正常能跑，2.1上面就出问题，报了如下的错：

错误给出了是哪儿出错，很明显是布局文件，然后还告诉了哪一行，也就是在哪个组件中定义属性出错，是Button。最后想不明白，是不是用了2.1不支持的属性，感觉不会，因为2.1不支持，最多也就不认，不至于会出错吧，反正这种情况是没遇到过。最后找到竟然是android:background属性定义的有错，不会呀，一直都是这么处理按钮图片的，换一组没有问题的自定义按钮的图片，一切OK，很无语，只能说明图片有问题，哪张图片有问题？一个个的试，最后就还真找出是那张图片的问题，倒底是图片什么问题？格式？大小？最后更无语的是竟然是图片上面多了点光晕效果引起的问题，还是2.1上面出现的问题，解决这个问题的还是直觉，感觉那个光晕不爽，去掉就OK了。估计是android的9Patch工具做的还不够好。折腾一个小时终于搞定了。
