使用这个

your_edittext.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View arg0) {

                    final Calendar calendar = Calendar.getInstance();
                    int yy = calendar.get(Calendar.YEAR);
                    int mm = calendar.get(Calendar.MONTH);
                    int dd = calendar.get(Calendar.DAY_OF_MONTH);
                    DatePickerDialog datePicker = new DatePickerDialog(getActivity(), new DatePickerDialog.OnDateSetListener() {
                        @Override
                        public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
                            String date = String.valueOf(dayOfMonth) + "/" + String.valueOf(monthOfYear+1)
                                    + "/" + String.valueOf(year);
                            your_edittext.setText(date);
                        }
                    }, yy, mm, dd);
                    datePicker.show();
                }
            });

用这个简单的技巧来做吧:

步骤1:创建一个片段对话框

public class DatePickerFragmentDialog  extends DialogFragment {

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        Calendar c = Calendar.getInstance();
        int year = c.get(Calendar.YEAR);
        int month = c.get(Calendar.MONTH);
        int day = c.get(Calendar.DAY_OF_MONTH);

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

}

第二步:在必要的活动中遵循这一点

该活动必须实现:DatePickerDialog。OnDateSetListener 在按钮上设置onClickListener: DialogFragment datePicker = new DatePickerFragmentDialog(); datePicker.show(getSupportFragmentManager()， "自定义日期选择器");

步骤3:覆盖OnDateSetListener

public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
        Calendar calendar = Calendar.getInstance();
        calendar.set(Calendar.YEAR, year);
        calendar.set(Calendar.MONTH, month);
        calendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);

        @SuppressLint("SimpleDateFormat") DateFormat dateFormat = new 
        SimpleDateFormat("MM/dd/yyyy");
        String currentDateString = dateFormat.format(calendar.getTime());

        tvPaymentDate.setText(currentDateString);
    }

因此，我们可以使用任何格式的日期:)

这是我怎么做的:类似于选择的答案，但使用一个静态对话框类，所以它更可重用，也使用onFocusChange而不是onClick。

editText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            if (hasFocus) {
                DialogFragment datePickerFragment = new DatePickerFragment() {
                    @Override
                    public void onDateSet(DatePicker view, int year, int month, int day) {
                        Log.d(TAG, "onDateSet");
                        Calendar c = Calendar.getInstance();
                        c.set(year, month, day);
                        editText.setText(df.format(c.getTime()));
                        nextField.requestFocus(); //moves the focus to something else after dialog is closed
                    }
                };
                datePickerFragment.show(getActivity().getSupportFragmentManager(), "datePicker");
            }
        }
    });

datepicker对话框。

public static class DatePickerFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener{

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        // Use the current date as the default date in the picker
        final Calendar c = Calendar.getInstance();
        int year = c.get(Calendar.YEAR);
        int month = c.get(Calendar.MONTH);
        int day = c.get(Calendar.DAY_OF_MONTH);

        // Create a new instance of DatePickerDialog and return it
        return new DatePickerDialog(getActivity(), this, year, month, day);
    }

    @Override
    public void onDateSet(DatePicker view, int year, int month, int day) {
        //blah
    }
}

 selectDate.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                DatePickerDialog  mdiDialog =new DatePickerDialog(mContext,new DatePickerDialog.OnDateSetListener() {
                    @Override
                    public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
                        Toast.makeText(getApplicationContext(),year+ " "+monthOfYear+" "+dayOfMonth,Toast.LENGTH_LONG).show();


                    }
                }, year, month, date);
                mdiDialog.show();

            }

        });

我不能得到这些工作中的任何人，所以将添加我的一个，以防它有帮助。

public class MyEditTextDatePicker  implements OnClickListener, OnDateSetListener {   
EditText _editText;
private int _day;
private int _month;
private int _birthYear;
private Context _context;

public MyEditTextDatePicker(Context context, int editTextViewID)
{       
    Activity act = (Activity)context;
    this._editText = (EditText)act.findViewById(editTextViewID);
    this._editText.setOnClickListener(this);
    this._context = context;
}

@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
    _birthYear = year;
    _month = monthOfYear;
    _day = dayOfMonth;
    updateDisplay();
}
@Override
public void onClick(View v) {
    Calendar calendar = Calendar.getInstance(TimeZone.getDefault());

    DatePickerDialog dialog = new DatePickerDialog(_context, this,
            calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH),
            calendar.get(Calendar.DAY_OF_MONTH));
    dialog.show();
    
}

// updates the date in the birth date EditText
private void updateDisplay() {

    _editText.setText(new StringBuilder()
    // Month is 0 based so add 1
    .append(_day).append("/").append(_month + 1).append("/").append(_birthYear).append(" "));
}
}

还有其他书里没有提到的东西。确保将以下内容放在EditText xml上。

android:focusable="false"

否则，就像在我的例子中，键盘会不断弹出。

选中的答案不太适合我，因为我必须点击EditText框一次，然后在OnClickListener启动之前再次点击它。我能够通过用OnTouchListener替换OnClickListener来修复这个问题，以防有人遇到类似的问题，下面是我的代码看起来是什么样的:

Calendar myCalendar = Calendar.getInstance();

DatePickerDialog.OnDateSetListener date = 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);
        updateLabel();
    }

};
edittext.setOnTouchListener(new View.OnTouchListener() {

    @Override
    public void onTouch(View v, MotionEvent event) {
        if(event.getAction() == MotionEvent.ACTION_DOWN) {
            new DatePickerDialog(classname.this, date, myCalendar
                    .get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
                    myCalendar.get(Calendar.DAY_OF_MONTH)).show();
        }
    }
});

private void updateLabel() {

    String myFormat = "MM/dd/yy"; //In which you need put here
    SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.US);

    edittext.setText(sdf.format(myCalendar.getTime()));
}
