java.lang.IllegalStateException：ViewPager尚未绑定（使用JakeWharton ViewPager指示器） [英] java.lang.IllegalStateException: ViewPager has not been bound (Using JakeWharton ViewPager Indicator)

问题描述

我有一个screen.One ViewPager两种查看传呼机使用JakeWhartoncircleindicator和第二个使用TabPage的指标。我需要使用异步call.Once的数据下载我应该显示在viewpagers将数据从后台下载数据。
这里是我的活动code片段。

I have two view pagers in a screen.One ViewPager uses JakeWharton' circleindicator and second one uses TabPage Indicator. I need to download the data from backend using Async call.Once the data is download i should be displaying the data in the viewpagers. Here is the Code snippet of my activity.

   ViewPager pager1;
ViewPager pager2;

public onCreate(){
     //I Set Up ContentView
     //Locate ViewPagers & Indicators
     //pager1 = ...
     //pager2= ...
     //Locate Indicators
     CallAsyncTask().execute();


}
private class CallAsyncTask extends AsynTask{
          doinbackground(){
          //Download Data
          }
          onPostExecute(){
            displayData();

          }

}
private displayData(){
   // Set Up Adapters & Indicators for ViewPagers
}

当我执行此code，我得到的 ViewPager未绑定异常。
是有它的溶液。我觉得一个解决方法是内部onPostExecute setUpContentView（）AsyncTask.But的方法我还需要显示progressBars直到数据下载即可。我怎样才能做到这一切。

when i execute this code, i get ViewPager Not Bound Exception. Is there a solution for it. I think a workaround is to setUpContentView inside onPostExecute() method of AsyncTask.But i also need to display progressBars till the data is downloaded. How can i achieve all of this.

推荐答案

我只是放在可见性：走了在 TabPageIndicator ，当我得到的数据显示更改知名度，可见

I just placed visibility: gone on the TabPageIndicator and when I get the data to display I change the visibility to visible
