解决方案

将这个在while循环

  MAP1 =新的HashMap＆LT;字符串，字符串＆GT;（）;
 

喜欢

 而（phones.moveToNext（））
{
    MAP1 =新的HashMap＆LT;字符串，字符串＆GT;（）;
    。
    。
}
 

Hi in my project i have to fetch a contacts phone number and the name from the phone.I can get call the phone number and name but when i add it to the ArrayList<HashMap<String, String>>i'm getting the only the last value i don't know why. but when i log it i'm getting all the value can u guys help me where did i go wrong

 public class Contacts  extends Activity {

            inflater = (LayoutInflater) context

            View itemView = inflater.inflate(R.layout.getcontactlist_view,

            // Get the position from the results
            resultp = new HashMap<String, String>();
            resultp = data.get(position);
            name = (TextView) itemView.findViewById(R.id.name);
            command = (TextView) itemView.findViewById(R.id.commamd);

            joinme= (Button) itemView.findViewById(R.id.getImage);
            name.setText(resultp.get("NAME"));
            Log.v("GET NAME", resultp.get("NAME"));

            if (resultp.get("COMMAND").equals("")) {
                command.setText("No Group");
            } else {
                command.setText(resultp.get("COMMAND"));
            }
            Log.v("GET COMMAND", resultp.get("COMMAND"));

            return itemView;
        }
    }

}

Put this in while loop

map1 = new HashMap<String, String>();

like

while (phones.moveToNext())
{
    map1 = new HashMap<String, String>();
    .
    .
}
