fragment嵌套遇到的问题

android开发的同学对fragment都不陌生 当然今天记录一个嵌套使用中的问题看错误如下

java.lang.IllegalArgumentException: Binary XML file line #93: Duplicate id 0x7f10046e, tag null, or parent id 0xffffffff with another fragment for com.XXX.fragment.XXXXFragment

解决方法
覆写fragmentA的onDestroyView方法，当fragmentA销毁的时候，手动销毁fragmentB。这个是stackoverflow提到的解决办法

@Override
public void onDestroyView() {  
super.onDestroyView(); 
 Fragment fragment = mActivity.getSupportFragmentManager().findFragmentById(R.id.fragment);  
  if(fragment != null){      
  mActivity.getSupportFragmentManager().beginTransaction().remove(fragment ).commit();  
}
