我有3个片段片段-A它底部有3个按钮，我将Fragment-B和Fragment-C放在Fragment-A的顶部。
当我在平板电脑上运行我的应用程序时，在左侧我显示包含列表视图的Fragment-B，在右侧我用ListView语言显示Fragment-C。当我更改语言时（通过在Fragment-C中进行选择），我可以更改Fragment-C的内容，但不能更改Fragment-A或Fragment-B。
我需要改变Fragment-A，Fragment-B＆amp; D的整个视图。片段-C但我不知道该怎么做。
我的代码是：
Fragment-A extends BluetoothControllerActivity implements OnClickListener {
String displayedLanguage;
/*
* Declaration Section
*/
/**
* Opens Display Fragment
*/
public Button mDisplayButton = null;
/**

//Will Loads Setting fragment

// Will Loads help fragment
loadHelpFragment();
break;
}
}
public void changeLanguage( String locale){
Configuration mConfiguration = new Configuration();
mConfiguration.locale = new Locale(locale);
//.getResources().updateConfiguration(mConfiguration, null);
getApplicationContext().getResources().updateConfiguration(mConfiguration, null);
}
/**

public void loadDisplayFragment()
{
//mDisplayButton.setFocusable(false);

fragmentTransaction = fragmentManager.beginTransaction();
//fragmentTransaction.addToBackStack(null);
Bundle args = new Bundle();
args.putString("digital", digitalString);
mDisplayFragment.setArguments(args);
fragmentTransaction.replace(R.id.holder_fragment, mDisplayFragment,"DisplayFragment");
//mDisplayFragment.getView().setEnabled(false);
fragmentTransaction.commit();
}
/**

*/
public void loadHelpFragment()
{
mDisplayButton.setClickable(true);
HelpFragment mHelpFragment = new HelpFragment();
fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.holder_fragment, mHelpFragment);
//fragmentTransaction.addToBackStack(null);

}
