您可以使用自定义列表视图来解决此问题。您可以使用列表视图扩展视图

list.setAdapter(CustomAdapter);

public class CustomAdapter extends BaseAdapter   implements OnClickListener {

         /*********** Declare Used Variables *********/
         private Activity activity;
         private ArrayList data;
         private static LayoutInflater inflater=null;
         public Resources res;
         ListModel tempValues=null;
         int i=0;

         /*************  CustomAdapter Constructor *****************/
         public CustomAdapter(Activity a, ArrayList d,Resources resLocal) {

                /********** Take passed values **********/
                 activity = a;
                 data=d;
                 res = resLocal;

                 /***********  Layout inflator to call external xml layout () ***********/
                  inflater = ( LayoutInflater )activity.
                                              getSystemService(Context.LAYOUT_INFLATER_SERVICE);

         }

         /******** What is the size of Passed Arraylist Size ************/
         public int getCount() {

             if(data.size()<=0)
                 return 1;
             return data.size();
         }

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

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

         /********* Create a holder Class to contain inflated xml file elements *********/
         public static class ViewHolder{

             public TextView text;
             public TextView text1;
             public TextView textWide;

             else

             if(data.size()<=0)
             {
                 holder.text.setText("No Data");

                  holder.text.setText( tempValues.getCompanyName() );

         @Override

               CustomListViewAndroidExample sct = (CustomListViewAndroidExample)activity;
