如何在Android上重置ViewPager内容? [英] How to reset viewpager content on Android?

问题描述

请告诉我如何在android上重置ViewPager的内容. 我尝试调用adapter.notifyDataSetChanged()，但是在滚动视图时适配器不调用getItem(position).它总是返回旧的子视图.

Please tell me how to reset the content of ViewPager on android. I tried to call adapter.notifyDataSetChanged() but the adapter doesn't call getItem(position) when I scroll the view. It always returns old child views.

更新:这是我的片段视图.当我重置viewPager数据时，它使用了加载的Fragment视图.它只是从onCreateView而不是Constructor开始.

Update: This is my Fragment View. When I reset viewPager data, It used loaded Fragment views. It's just start at the onCreateView instead of Constructor.

public class ResultView extends Fragment {
//Declare properties

     //Constructor 
public ResultView(Province province, Calendar calendar) {
    Log.d("xskt", "ResultView constructor");
    this.province = province;
    this.calendar = (Calendar) calendar.clone();
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    Log.d("xskt", "ResultView onCreateView");
    View view = inflater.inflate(R.layout.resultview, null);

    //do some thing

    return view;
}

谢谢.
