            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;
        }
    }

}

推荐答案

将其放入 while 循环

Put this in while loop

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

喜欢

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