1、异常信息

Process: , PID: 32509
     : Binary XML file line #23 in :layout/devbyte_item: Binary XML file line #23 in :layout/devbyte_item: Error inflating class 
     Caused by: : Binary XML file line #23 in :layout/devbyte_item: Error inflating class 

2、分析流程

根据搜索以及分析,可以知道是因为 inflate layout file时出错,那么可能的原因是:

  1. 自定义View类定义出错,常见的为少了构建函数:public MyView(Context context,AttributeSet paramAttributeSet)。该错误是使用时出错,所以不符合;
  2. 定义类引用为题:如写一个自定义view,引用的时候需要用完整路径;
  3. 资源文件不存在或者找不到。不存在比较好判别,存在但是找不到可能的原因是不同分辨率的drawable下文件夹的资源,如果只在一个文件下放了资源文件,不同的分辨率设备的会报错;
  4. 可能是编码问题;
  5. 内存泄漏;
  6. Application主题与组件风格不符合,比如application主题是,但是组件却是,这时,也可能出错(本文就是如此);
  7. 风格使用对象不对,比如TextViewText Style时,应该使用style,而不是android:style

3、所获

  1. 遇到layout file无法inflate时,应该尽可能地分析是什么原因导致无法使用,可能的原因就是某个地方出错,导致无法使用,可以考虑的方向:自定义View是否正确;属性是否设置正确;是否引用了不存在的资源;使用View方法是否正确;主题是否使用一致等。
  2. 仔细分析异常栈,由上向下,越往下,原因可能就更明显。
