Question

我有一个带有viewpager的PagerSlidingTabStrip，它包含三个片段。其中一个片段有ListView，当我在ListView项目上向左或向右滑动时，viewpager不会更改页面，当我在ListView滚动外滑动工作正常。当我在仅包含TextView的其他片段上滑动时，滑动正在工作。请建议，我可能做错了什么？

只需在PagerSlidingTabStrip的示例代码中添加以下片段和适配器即可重现此问题。

@SuppressLint("ValidFragment")
public class HomeFragment extends Fragment {


    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = null;
        try {
            view = inflater.inflate(R.layout.home, container, false);
            ListView listview = (ListView) view.findViewById(R.id.homegrid);

            listview.setAdapter(new HomeAdapter(inflater));
        }
        catch (Exception e)
        {
            e.printStackTrace();
        }

        return view;
    }
}

public class HomeAdapter extends BaseAdapter {
    private Context mContext;
    LayoutInflater inflater;

    public HomeAdapter( LayoutInflater inflater)
    {
        this.inflater = inflater;
    }

    public int getCount() {
        return 5;
    }

    public Object getItem(int position) {
        return null;
    }

    public long getItemId(int position) {
        return 0;
    }

    public View getView(int position, View convertView, ViewGroup parent) {
        if (convertView == null) {  // if it's not recycled, initialize some attributes
            convertView = inflater.inflate(R.layout.home_grid_item, parent, false);
        }
       TextView text1 =  (TextView)convertView.findViewById(R.id.title);
        text1.setText("FAVOURITE "+position);

        return convertView;
    }


}

Answer 1

包含带有android：singleLine =“true”的TextView的ViewPager导致了这个问题。这个问题已在下面的问题中讨论和回答。

can not scroll the ViewPager when touching TextView(with android:gravity="center") in it

PagerSlidingTabStrip ViewPager不滚动
