Fragment UI在加载时出现奇怪的行为

Question

好的，所以我有一个Android应用程序，它为每个视图使用内置的NavigationDrawer Activity with Fragments。其中一个视图从Web服务中提取一些数据，但由于数据在一天内没有变化，我将值存储在首选项中以及打开选项卡的那一天的时间戳，以便Web服务方法不是每次用户打开该选项卡时都会调用。我遇到的问题是，当时间戳部分移动到更新视图的代码部分时，某些项目没有正确绘制（有些项目被压扁而其他项目没有显示正确的位置屏幕）。如果我单击刷新按钮来调用Web服务方法，然后以这种方式更新视图，它总是正确地绘制它们。我不知道我在哪里弄乱，但我确定这是我，因为Android对我来说很新鲜。

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.fragment_sales, container, false);

    thisActivity = this.getActivity();

    mtdHeaderTextView = (TextView)rootView.findViewById(R.id.mtdHeaderText);
    mtdSeekBar = (SeekBar)rootView.findViewById(R.id.mtdSeekBar);
    mtdTopSeekBar = (SeekBar)rootView.findViewById(R.id.mtdTopSeekBar);
    mtdValueTextView = (TextView)rootView.findViewById(R.id.mtdValueTextView);
    mtdGoalTextView = (TextView)rootView.findViewById(R.id.mtdGoalTextView);
    mtdDateTextView = (TextView)rootView.findViewById(R.id.mtdDateTextView);

    return rootView;
}
@Override
public void onResume() {
    super.onResume();
    CheckTimeStamp();
}

public static void CheckTimeStamp() {
    SharedPreferences preferences = HelperClass.PreferenceFileName(thisActivity);
    String timeStamp = preferences.getString(Constants.keySalesTimeStamp, "");
    Calendar calendar = Calendar.getInstance();
    Date date = calendar.getTime();
    String currentTime = HelperClass.GetSimpleDateFormat(date);
    if (currentTime.equals(timeStamp)) {
        foundMTDValue = preferences.getString(Constants.keyMTDValue, "");
        foundYTDValue = preferences.getString(Constants.keyYTDValue, "");
        UpdateMTDProgress();-->this is the method that adds values to the textviews and seekbars
    }
    else {
        SharedPreferences.Editor editor = preferences.edit();
        editor.putString(Constants.keySalesTimeStamp, currentTime);
        editor.apply();
        GetMTDValue(); -->this calls the web service to get values and then calls UpdateMTDProgress like above
    }
}

以下是UpdateMTDProgres部分的代码

public static void UpdateMTDProgress() {
    //First update Header Text View
    SharedPreferences preferences = HelperClass.PreferenceFileName(thisActivity);
    int mtdGoal = preferences.getInt(Constants.keyMonthlyGoal, 0);
    double percentage = Double.parseDouble(foundMTDValue) / mtdGoal;
    NumberFormat format = NumberFormat.getPercentInstance();
    String percentageString = format.format(percentage);
    mtdHeaderTextView.setText("MTD Commissions (" + percentageString + ")");
    //Get Current Date and Number of Days in Month
    Calendar calendar = Calendar.getInstance();
    int currentDay = calendar.get(Calendar.DAY_OF_MONTH);
    int totalDays = calendar.getActualMaximum(Calendar.DAY_OF_MONTH);
    //Get Daily Goal for Rep based on mtdGoal and number of days
    int dailyGoal = mtdGoal/totalDays;
    //Get current day goal
    int currentDayGoal = dailyGoal * currentDay;
    //Check if current mtd value against currentdaygoal
    if (Double.parseDouble(foundMTDValue) >= currentDayGoal) {
        mtdSeekBar.setProgressDrawable(thisActivity.getResources().getDrawable(R.drawable.seekbar_green));
    }
    else {
        mtdSeekBar.setProgressDrawable(thisActivity.getResources().getDrawable(R.drawable.seekbar_red));
    }
    //update progress seekbar values
    mtdSeekBar.setMax(mtdGoal);
    mtdSeekBar.setProgress((int) Double.parseDouble(foundMTDValue));
    //update indicator seekbar values
    mtdTopSeekBar.setMax(totalDays);
    mtdTopSeekBar.setProgress(currentDay);
    //Update Current Value and Goal TextViews
    String currentValueString = HelperClass.ConvertStringToCurrency(foundMTDValue);
    mtdValueTextView.setText(currentValueString);
    String goalValueString = HelperClass.ConvertStringToCurrency(String.valueOf(mtdGoal));
    mtdGoalTextView.setText(goalValueString);
    Date date = calendar.getTime();
    SimpleDateFormat dateFormat = new SimpleDateFormat("MMM dd");
    String shortDate = dateFormat.format(date);
    mtdDateTextView.setText(shortDate);
