I have a button and when I click on it, I want it to show a listview with image & text (static text). How can I do this?

My code..
public class category extends ListActivity {
    Button category;
    TextView selection;
    private static final String[] country = { "Iceland", "India", "Indonesia",
         "Iran", "Iraq", "Ireland", "Israel", "Italy", "Laos", "Latvia",
         "Lebanon", "Lesotho ", "Liberia", "Libya", "Lithuania",
         "Luxembourg" };
         private static final String[] curr = { "ISK", "INR", "IDR", "IRR", "IQD",
         "EUR", "ILS", "EUR", "LAK", "LVL", "LBP", "LSL ", "LRD", "LYD",
         "LTL ", "EUR"

         };
    /** Called when the activity is first created. */
    @Override

        super.onCreate(savedInstanceState);
        setContentView(R.layout.category);

        category=(Button)findViewById(R.id.category);



        class EfficientAdapter extends BaseAdapter {
             private LayoutInflater mInflater;

             public EfficientAdapter(OnClickListener onClickListener) {
             mInflater = LayoutInflater.from((Context) onClickListener);

             }

             public int getCount() {
             return country.length;
             }

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

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

             public View getView(int position, View convertView, ViewGroup parent) {
             ViewHolder holder;
             if (convertView == null) {
             convertView = mInflater.inflate(R.layout.listview, null);
             holder = new ViewHolder();
             holder.text = (TextView) convertView
             .findViewById(R.id.TextView01);
             holder.text2 = (TextView) convertView
             .findViewById(R.id.TextView02);

             convertView.setTag(holder);
             } else {
             holder = (ViewHolder) convertView.getTag();
             }

             holder.text.setText(curr[position]);
             holder.text2.setText(country[position]);

             return convertView;
             }

             class ViewHolder {
             TextView text;
             TextView text2;
             }
             }
        category.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {

                ListView l1 = (ListView) findViewById(R.id.ListView);
                 l1.setAdapter(new EfficientAdapter(this));

            }   

        });

    }   

}


  • "R.layout.listview" in this layout file ,which u r inflating in getView method, add one imageview.

  • Now add imageview in view holder in place of second textview text2.

    class ViewHolder {  
        TextView text;  
        ImageView IM2;  
    }
    
  • Do this in getView:

    holder.IM2 = (ImageView) convertView
                 .findViewById(R.id.ImageView02);
    
  • In place of holder.text2.setText(country[position]);, set a background image on your imageview.

ex. holder.IM2.setBackgroundDrawable(getResources().getDrawable(R.drawable.vimage));

Thanks.
