Answer 1

android.view.InflateException: Binary XML file line #8: Error inflating class cm.test.testview

1. 确认准确包名 “cm.test.testview” -->
2. 确认 inflate 使用
[code] 三种方式可以生成LayoutInflater：
　　
　　LayoutInflaterinflater=LayoutInflater.from(this);
　　
　　LayoutInflaterinflater=getLayoutInflater();
　　
　　LayoutInflaterinflater=(LayoutInflater)this.getSystemService(LAYOUT_INFLATER_SERVICE);
　　
　　然后调用inflate方法将xml布局文件转成View
　　
　　publicViewinflate(intresource,ViewGrouproot,booleanattachToRoot)
　　
　　在View类中，也有inflate方法
　　
　　publicstaticViewinflate(Contextcontext,intresource,ViewGrouproot)
[/code]

Answer 2

目测是你的自定义testview在inflate的时候出错了。
