Java Textview和ImageButton可见状态和RunOnUIThread 背景

我正在调用okhttp

newcall（request）.enqueue（…）

方法，如果失败，我将使用监听器返回主活动，在这里我显示文本框和图像按钮，要求用户重新加载。我正在使用

RunOnUIThread

更改视图状态

ImageRequester.java

mClient.newCall(request).enqueue(new Callback() {
        @Override
        public void onFailure(Call call, IOException e) {
            mLoadingData = false;
            mLoadingDataFailed = true;
            e.printStackTrace();

           // send exception/fail response to MainActivity
            mResponseListener.recieveException(e);

        }

@Override
    public void recieveException(Exception exp) {
        runOnUiThread(new Runnable() {
            @Override
            public void run() {
                if(mFirstTime) {
                    mProgressBar.setVisibility(View.VISIBLE);
                    mProgressTextView.setVisibility(View.VISIBLE);
                    reloadButton.setVisibility(View.VISIBLE);
                }
                if (!mFirstTime) {
                    toolbarPbar.setVisibility(View.GONE);
                    mShouldReload = true;
                    invalidateOptionsMenu();
                    Snackbar.make(findViewById(android.R.id.content), "Checking your internet connection might help.", Snackbar.LENGTH_LONG).show();
                }

问题 当我在设备上运行应用程序时，

receiveexception（…）

方法中的

Textview

和

ImageButton

重新加载按钮

中的

mProgressTextView

方法不会显示（

settingvisibility（view.VISIBLE）

）。但mProgressBar可以看到，并且条件正常工作。和每当我单击菜单视图时，

mProgressTextView

和

reload按钮都将可见。
我尝试了
invalidate
和
postInvalidate
方法，但都没有成功

我不知道发生了什么事。请开导我

p.S.
我不熟悉安卓系统
