片段保存实例状态，但从不重新加载它

Question

我无法重新加载我的片段状态。

架构是这样的：

我的Activity A Fragment F。使用选项菜单Activity A打开SettingsActivity及其SettingsFragment（带startActivity()）。在此期间，Fragment F执行常规操作，调用onSaveInstanceState，onPause，onStop。一切都很好。

用户点击后退按钮后，SettingsActivity会关闭，Fragment F应重新初始化。问题开始了。 Fragment F不会再次致电onCreateView。它也不会调用onActivityCreated。调用的第一个方法是onStart。

那么在哪里可以捕获我的savedInstanceState Bundle以重新初始化我的自定义成员变量？

为什么Fragment F成员变量（指向片段中的某些视图）仍然（或再次？）初始化。

感谢您的帮助！

以下是一些代码段：

片段F

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
    Log.d(this, "onCreateView");
    return Butterknife.bind(this, inflater.inflate(R.layout.fragment_video_mockup, container, false));
}
@Override
public void onActivityCreated(Bundle savedInstanceState)
{
    Log.d(this, "onActivityCreated");
    super.onActivityCreated(savedInstanceState);
    if(savedInstanceState != null)
    {
        Log.d(this, "... loading from saved instance");
        this.initFromArgument(savedInstanceState.getBundle(ARG_SAVED_STATE));
    }
    else if(this.getArguments() != null)
    {
        Log.d(this, "... loading from external arguments");
        this.initFromArgument(this.getArguments());
    }
}
@Override
public void onSaveInstanceState(Bundle outState)
{
    super.onSaveInstanceState(outState);
    Log.d(this, "... saving");
    outState.putBundle(ARG_SAVED_STATE, createArgument(this.waveform, this.sequencer, this.paths));
}

活动A

@Override
public boolean onOptionsItemSelected(MenuItem item)
{
    Log.d(this, "options menu selected (" + item.getTitle() + ")");
    switch(item.getItemId())
    {
        case R.id.action_settings:
            this.startActivity(new Intent(MainActivity.this, SettingsActivity.class));
            break;
        case R.id.action_feedback:
            this.onFeedbackClick();
            break;
        default:
            throw new AssertionError("wrong option item selected");
    }
    return super.onOptionsItemSelected(item);
}
