这个问题是Google4.0原生的FW Bug。大概就是4.0之后默认开启硬件加速功能。

导致在eclipse里面编译没有，在源代码中编译有，后来找到原因，是源码编译打开了硬件加速导致的

解决方法1 java中:

View.setLayerType(View.LAYER_TYPE_SOFTWARE, null);  //View 就是你的view

解决方法2AndroidManifest.xml中 :

就是在AndroidManifest.xml中禁用硬件加速，可以写在Application标签里，也可以写在Activity里

android:hardwareAccelerated = "false"
