android.view.InflateException: B

背景

测试发现个bug, 在华为mate9使用app会报错，其它手机是正常的

具体报错信息如下

    java.lang.RuntimeException: Unable to start activity ComponentInfo{packname/activity path}: android.view.InflateException: Binary XML file line #6: Binary XML file line #6: Error inflating class <unknown>

解决

这个问题是由于使用了activitygroup造成的，之前一直以为是activitygroup兼容性问题，后面才发面子activity调用了setTheme引起的，大概结构如下:

class PatientDynamicMessageActivity extends ActivityGroup{}

class Activity1 extends Activity(){}

class Activity2 extends SuperActivity(){
 protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setTheme();//调用这个还原主工程主题就可以解决
  }
}

class SuperActivity extends Activity(){
     protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

         setContentView(R.layout.test);
         setTheme(R.style.test);//就是这一行代码引起的
      }
}
