Question

我有一个片段和okhttpp客户端。当我在片段内发出请求时，okhttp得到200响应ID就像在片段中设置mProgressBar.setVisibility(View.GONE);一样。但遗憾的是没有任何反应。我得到了一个响应，它的确定，代码转到mProgressBar.setVisibility(View.GONE);的行，但没有任何反应，mProgressBar仍在显示，但是日志显示mProgressBar not visible。为什么这样？

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
    View rootView = inflater.inflate(R.layout.fragment_shemas, container, false);
    ls = (Ls) getActivity().getApplicationContext();
    mProgressBar = rootView.findViewById(R.id.pb_fr_schema);

    mClient = ls.createClient(getActivity());
    Log.d(TAG, "Назначили OkHttpClient " + mClient.toString() + " для " + this.getClass().toString() + " в " + this.getClass().toString());

    try
    {
        String url = ls.baseUrl + ls.getLsId() + "/" + ls.getCurrBidId() + "/call-fwd-settings/overview";
        requestOkHttp(url, "GET", "");
    } catch (IOException e)
    {
        e.printStackTrace();
    }

    mSpinner = (Spinner) rootView.findViewById(R.id.sp_fr_schemas_did);
    // Список номеров
    ArrayList<String> didsNames = new ArrayList<>();
    for (Map.Entry<String, Bid> pr : ls.getProducts().entrySet())
    {
        didsNames.add(pr.getValue().getBidName());
    }

    mAdapter = new ArrayAdapter<String>(getActivity(), R.layout.spinner_row_products, R.id.tv_bid_name, didsNames);
    // Чтобы был читаемый дизайн при выборе DID
    mAdapter.setDropDownViewResource(R.layout.spinner_row_products);
    //spinner.setAdapter(mAdapter);
    return inflater.inflate(R.layout.fragment_shemas, container, false);
}

这是okhttp响应代码

getActivity().runOnUiThread(new Runnable(){
@Override
public void run(){
// Отключаем mProgressBar
mProgressBar.setVisibility(View.GONE);
if (mProgressBar.getVisibility() == View.VISIBLE) {
Log.d(TAG, " mProgressBar visible");
} else {
Log.d(TAG, " mProgressBar not visible");
}
}
});

我找到了解决方案。问题发生在return。我将此return inflater.inflate(R.layout.fragment_shemas, container, false);更改为此return rootView;，现在已确定。

如何从其他线程修改片段视图？
