包含在SlidingMenu中的Viewviewr的Listview -Android

Question

In my project,listview contains viewpager for loading images.Actually this listview is loaded in a fragment which uses sliding menu .

Here the problem is layout is neither loading nor showing any errors.

I used pagecontainer like this s://gist.github.com/devunwired/8cbe094bb7a783e37ad1

My Adapter class

 public class SampleAdapter extends BaseAdapter {

private Activity activity;
private String[] titleData;
private int[] imageData;
private ArrayList<Request> List;
PagerContainer mContainer;
MyPagerAdapter adapter;

public SampleAdapter(Activity a, ArrayList<Request> list) {
    activity = a;
    List = new ArrayList<Request>();
    List = list;


}

@Override
public int getCount() {
    return List.size();
}

@Override
public Object getItem(int position) {
    return position;
}

@Override
public long getItemId(int position) {
    return position;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {

    LayoutInflater inflater = (LayoutInflater) activity.getSystemService(
                    Context.LAYOUT_INFLATER_SERVICE);
    View rowView = inflater.inflate(R.layout.cus_hub_list, parent, false);

    mContainer = (PagerContainer) rowView.findViewById(R.id.pager_container);

    ViewPager pager = mContainer.getViewPager();


    adapter = new MyPagerAdapter();


    pager.setAdapter(adapter);


    pager.setOffscreenPageLimit(adapter.getCount());
    pager.setPageMargin(15);
    pager.setClipChildren(false);

    return rowView;
}

public  class MyPagerAdapter extends PagerAdapter {

    @Override
    public Object instantiateItem(ViewGroup container, int position) 
    {
        TextView view = new TextView(activity);
        view.setText("Item " + position);
        view.setGravity(Gravity.CENTER);
        view.setBackgroundColor(Color.argb(255, position * 50,
                position * 10, position * 50));

        container.addView(view);
        return view;
    }

    @Override
    public void destroyItem(ViewGroup container, int position, Object object) {
        container.removeView((View) object);
    }

    @Override
    public int getCount() {
        return 5;
    }

    @Override
    public boolean isViewFromObject(View view, Object object) {
        return (view == object);
    }

    @Override
    public int getItemPosition(Object object) {
           return POSITION_NONE;
        }
}

}

But the problem is listview not showing any list items .

Can anybody figure out the problem.

Thanks in Advance.

Answer 1

Your SampleAdapter , while having the list of items it manages, never does anything with them in the getView method. It is to be expected that nothing is showing up!

I would suggest you use a ViewHolder as explained in this question to populate all the items you want to show and then visualise them using the convertView parameter of the getView method.

Please consider this tutorial for an introduction on the Holder Pattern and how to set the contents of a List for your View .

Answer 2

在您的寻呼机中，而不是wrap_content中，以dp指定一个高度。该高度可以根据屏幕大小进行调整
