android開發(fā)的同學對fragment都不陌生 當然今天記錄一個嵌套使用中的問題看錯誤如下

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

解決方法
覆寫fragmentA的onDestroyView方法，當fragmentA銷毀的時候，手動銷毀fragmentB。這個是stackoverflow提到的解決辦法

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