Question

我在我的应用程序中使用DatePickerDialog。这是碎片。现在，问题是，当我在EditText上休息时，它打开对话3次。

我在这里为2个不同的DatePickerDialog和2个EditText使用了2个TimePickerDialog的总计2 EditText。
我的代码：

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {

((EditText) etIOStartDate).setOnTouchListener(new View.OnTouchListener() {

    @Override
    public boolean onTouch(View v, MotionEvent event) {
    // TODO Auto-generated method stub

        new DatePickerDialog(getActivity(), StartDate, myCalendar.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH), myCalendar.get(Calendar.DAY_OF_MONTH)).show();
    return false;
    }
});
}
DatePickerDialog.OnDateSetListener StartDate = new DatePickerDialog.OnDateSetListener() {

        @Override
        public void onDateSet(DatePicker view, int year, int monthOfYear,
                int dayOfMonth) {
            // TODO Auto-generated method stub

            myCalendar.set(Calendar.YEAR, year);
            myCalendar.set(Calendar.MONTH, monthOfYear);
            myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);

            String myFormat = "dd-MM-yyyy";
            SimpleDateFormat sdf = new SimpleDateFormat(myFormat,
                    Locale.getDefault());

            ((EditText) etIOStartDate)
                    .setText(sdf.format(myCalendar.getTime()));
        }
    };

请帮我解决问题。

Answer 1

试试这个。有两个事件Action down和Action up。

((EditText) etIOStartDate).setOnTouchListener(new View.OnTouchListener() {

        @Override
        public boolean onTouch(View arg0, MotionEvent arg1) {
            // TODO Auto-generated method stub
            switch(arg1.getAction())
            {
            case MotionEvent.ACTION_DOWN :
                new DatePickerDialog(getActivity(), StartDate, myCalendar.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH), myCalendar.get(Calendar.DAY_OF_MONTH)).show();
                break;
            case MotionEvent.ACTION_UP  :
                break;

            }

            return true;
        }
    });

将setOnClickListener改为EditText

你已经使用了setOnTouchListener，所以它会发现2-3次触摸，所以它会打开

Answer 3

你必须维护一个全局变量来检查你的datepicker是否被打开。当您打开datepicker时，将该变量赋值为true。

boolean isDatePickerOpened=false;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {

((EditText) etIOStartDate).setOnTouchListener(new View.OnTouchListener() {

    @Override
    public boolean onTouch(View v, MotionEvent event) {
    // TODO Auto-generated method stub

if(!isDatePickerOpened){

   isDatePickerOpened=true;
        new DatePickerDialog(getActivity(), StartDate, myCalendar.get(Calendar.YEAR),       myCalendar.get(Calendar.MONTH), myCalendar.get(Calendar.DAY_OF_MONTH)).show();
}
    return false;
    }
});
}


DatePickerDialog.OnDateSetListener StartDate = new DatePickerDialog.OnDateSetListener() {

        @Override
        public void onDateSet(DatePicker view, int year, int monthOfYear,
                int dayOfMonth) {
            // TODO Auto-generated method stub

            myCalendar.set(Calendar.YEAR, year);
            myCalendar.set(Calendar.MONTH, monthOfYear);
            myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);

            String myFormat = "dd-MM-yyyy";
            SimpleDateFormat sdf = new SimpleDateFormat(myFormat,
                    Locale.getDefault());

            ((EditText) etIOStartDate)
                    .setText(sdf.format(myCalendar.getTime()));

                isDatePickerOpened=false;

        }
    };

当日期选择器对话框被解除时，您必须将isDatePickerOpened设置为false。这可能对你有帮助..

在onCreate（）

下使用此功能

txtDate = (EditText) findViewById(R.id.etSdate);
txtDate.setOnClickListener(new View.OnClickListener() 
{
        @Override
        public void onClick(View v) 
        {
            etSdate();
        }

});

在程序结束时调用此函数

public void etSdate()
   {
       {

            // Process to get Current Date
            final Calendar c = Calendar.getInstance();
            mYear = c.get(Calendar.YEAR);
            mMonth = c.get(Calendar.MONTH);
            mDay = c.get(Calendar.DAY_OF_MONTH);

            // Launch Date Picker Dialog
            DatePickerDialog dpd = new DatePickerDialog(this,
                    new DatePickerDialog.OnDateSetListener() {

                        @Override
                        public void onDateSet(DatePicker view, int year,
                                int monthOfYear, int dayOfMonth) {
                            // Display Selected date in textbox
                            txtDate.setText(dayOfMonth + "-"
                                    + (monthOfYear + 1) + "-" + year);

                        }
                    }, mYear, mMonth, mDay);
            dpd.show();


  }
}

触摸EditText时，DatePickerDialog会多次打开
