android - 刷新 fragment android

Question

早些时候这段代码是有效的，但现在它突然停止工作了。 fragment 没有脱离父 Activity 。

public void reLoadFragment(Fragment fragment)
{
    Log.i(LogGeneratorHelper.INFO_TAG, "reloading fragment");
    // Reload current fragment
    Fragment frg = null;
    frg = getSupportFragmentManager().findFragmentByTag(fragment.getClass().getName());
    frg.onDetach();
    final FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
    ft.detach(frg);
    ft.attach(frg);
    ft.commit();
    Log.i(LogGeneratorHelper.INFO_TAG, "reloading fragment finish");
}

Answer 1

ft.detach() 在支持库更新 25.1.0 后不工作。此解决方案在更新后工作正常:

getSupportFragmentManager().beginTransaction().detach(oldFragment).commitNowAllowingStateLoss();
getSupportFragmentManager().beginTransaction().attach(oldFragment).commitAllowingStateLoss(); 

信用: Refresh or force redraw the fragment
