java - 触摸时，日期选择器会出现两次

Question

我正在尝试在我的应用程序中实现日期选择器。但我遇到了一个问题。

当我单击文本字段时，日期选择器的日历出现两次。如何解决这个问题？

这是代码:

public class EventFragment extends Fragment {

    private Calendar cal;
    private int day;
    private int month;
    private int year;
    private EditText et_startDate;
    private EditText et_endDate;
    private Button btn_create;
    private EditText et_eventname;
    private EditText et_venue;
    private EditText et_description_new;
    TimePicker timePicker;
    private DatabaseHandler mySQLiteAdapter;
    private Calendar calendar;

    static final int DATE_DIALOG_ID1 = 0;
    static final int DATE_DIALOG_ID = 1;

    public EventFragment() {
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        // To connect to database
        mySQLiteAdapter = new DatabaseHandler(getActivity());

        rootView = inflater.inflate(R.layout.fragment_event, container, false);

Answer 1

将其放入 edittext xml

android:focusable="false"

用 setOnClickListener 交换 setOnTouchListener

    et_startDate.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            DialogFragment newFragment = new SelectDateFragment();
            newFragment.show(getFragmentManager(), "DatePicker");

        }
    });
