Question

我正在创建一个需要从user获取日期的android活动。我的活动在触摸时有一个编辑文本显示了datepicker对话框并在编辑文本中显示了日期。我已经使用Datepickerdialog完成了它。我的问题当我点击edittext 2时会显示datepickerdialog。

这是我的代码......

Activity.class

EditText startDate;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_add_event);
    startDate= (EditText) findViewById(R.id.startdate);
    startDate.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            new DatePickerDialogFragment().show(getFragmentManager(),"DatePicker");

            return true;
        }
    });
}

@Override
public void returnDate(String date) {
    startDate.setText(date);
}

DatepickerDialog类

public class DatePickerDialogFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener {

TheListener listener;

public interface TheListener{
    public void returnDate(String date);
}
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    Calendar calendar=Calendar.getInstance();
    int year=calendar.get(Calendar.YEAR);
    int month=calendar.get(Calendar.MONTH);
    int day=calendar.get(Calendar.DAY_OF_MONTH);
    listener = (TheListener) getActivity();


    return new DatePickerDialog(getActivity(),this,year,month,day);
}

@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
    Calendar c=Calendar.getInstance();
    c.set(year,monthOfYear,dayOfMonth);

    SimpleDateFormat dateFormat=new SimpleDateFormat("dd-MM-yyyy");
    String date=dateFormat.format(c.getTime());
    if(listener!=null)
    {
        listener.returnDate(date);
    }

}
}

我的代码中有什么问题。以及如何解决它。

Answer 1

使用ACTION_UP动作事件

编写这样的代码

 @Override
            public boolean onTouch(View view, MotionEvent motionEvent) {
                if (motionEvent.getAction() == MotionEvent.ACTION_UP) {
                    new DatePickerDialogFragment().show(getFragmentManager(),"DatePicker");                      
                }
                return false;
            }

我通过仅添加条件hasFocus然后调用该方法解决了此问题。它解决了我的问题。

在XML部分中：我将属性添加到EditText：

android:focusable="false"

在主活动中的onCreate方法下：

dateinput.setInputType(InputType.TYPE_NULL); //keyboard disappear
            dateinput.setOnFocusChangeListener(new View.OnFocusChangeListener() {
                @Override
                public void onFocusChange(View v, boolean hasFocus) {
                    if (hasFocus) {
                        showDateDailogForm(dateinput);
                    }
                }
            });

在onCreate方法之外的主活动中：

    private void showDateDailogForm(final EditText dateinput) {
            Calendar calendar = Calendar.getInstance();
            DatePickerDialog.OnDateSetListener dateSetListener = new DatePickerDialog.OnDateSetListener() {
                @Override
                public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
                    calendar.set(Calendar.YEAR, year);
                    calendar.set(Calendar.MONTH, month);
                    calendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
                    SimpleDateFormat simpleDateFormat = new SimpleDateFormat("dd/MM/yyyy");
                    dateinput.setText(simpleDateFormat.format(calendar.getTime()));
                }
            };
            new DatePickerDialog(MainActivity.this, dateSetListener, calendar.get(Calendar.YEAR),
                    calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH)).show();
        }

日期选择器对话框显示多次
