Question

您好，在我的项目中，我必须从手机上取一个联系人电话号码和姓名。我可以拨打电话号码和姓名，但是当我将其添加到ArrayList<HashMap<String, String>>时我只能获得最后的价值我不知道为什么。但当我记录它时，我得到了所有的价值，你们可以帮助我哪里出错了

 public class Contacts  extends Activity {
    Button btnGetContacts;
    int z = 1;
    String namereview = null;
    public String phoneNumber1 = "", phoneNumber, name1, url,urljoingroup;
    ListView listSliding;
    Button slideHandleButton;
    HashMap<String, String> map1;

    ListContactAdaptor allContactAdapter;
    ArrayList<HashMap<String, String>> arraylist = new ArrayList<HashMap<String, String>>();
    HashMap<String, String> resultp = new HashMap<String, String>();
    String name;
    String message = null;
    String sGetContactUrl;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.getcontactlist_main);
        listSliding = (ListView) findViewById(R.id.GetContacts_Listview);
        customer_contact();

    }


    @SuppressLint("NewApi")
    public void customer_contact() {

        int timescount = 1, y = 1;
        map1 = new HashMap<String, String>();
        Cursor phones = getContentResolver().query(
                ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null,
                null, null);

        while (phones.moveToNext()) {


                name = phones
                        .getString(phones
                                .getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));

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

            if (resultp.get("COMMAND").equals("")) {

            } else {
                command.setText(resultp.get("COMMAND"));

将此放入while循环

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

像

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

联系人在Arraylist中添加ListView错误
