I Need To Add A Imageview Or Webview In My Listview

I got a problem. I got some code which I'm not going to put all here because it's to big. But I got a listview. And i do it like this: lv = (ListView) findViewById(R.id.list); (He

Solution 1:

At first,

WebView takes more memory than ImageView. So I recommend you to use ImageView.

At Second,

Check out following URLs.

Lazy load of images in ListView

In this article, The first library, which I have used, is small and customizable library. It uses thread pool and seems to control transfers. The second library, which I haven't used, is larger. But more methods in this library seem to make it easy to control various configurations.

Finally,

I think you should create your own Adapter, extending SimpleAdapter(or CursorAdapter, or…). like following pseudo code.

public class MySimpleAdapter extends SimpleAdapter {
    private ImageLoader mImageLoader;
    private int mResource;
    private LayoutInflater inflater;
    public static class ViewHolder {
        public ImageView img;
        public TextView txt;
    }

    public MySimpleAdapter(Context context, List<? extends Map<String, ?>> data, int resource, String[] from, int[] to) {
        super(context, data, resource, from, to);
        mResource = resource;
        mImageLoader = new ImageLoader(context);
        inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder holder;
        if (convertView == null) {
            convertView = inflater.inflate(R.layout.cell_text, null);
            holder      = new ViewHolder();
            holder.txt  = (TextView) convertView.findViewById(R.id.txt);
            holder.img  = (ImageView) convertView.findViewById(R.id.img);
            convertView.setTag(holder);
        }
        else {
            holder = (ViewHolder) convertView.getTag();
        }
        holder.txt.setText("something text");
        mImageLoader.displayImage("url", holder.img);
        return convertView;
    }
}

Solution 2:

You Can use [androidQuery]https://code.google.com/p/android-query/ It has a thread pool. It load images in different ways. Has the option to down sample images to save memory. Made by google :)
