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();
                }
            });

我认为最好重写EditText类…

public class EditTextDP extends android.support.v7.widget.AppCompatEditText implements View.OnClickListener, DatePickerDialog.OnDateSetListener {
    public EditTextDP(Context context) {
        super(context);
        setOnClickListener(this);
        setFocusable(false);
    }

    public EditTextDP(Context context, AttributeSet attrs) {
        super(context, attrs);
        setOnClickListener(this);
        setFocusable(false);
    }

    public EditTextDP(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        setOnClickListener(this);
        setFocusable(false);
    }

    @Override
    public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
        setText(new StringBuilder().append(dayOfMonth).append("/").append(monthOfYear + 1).append("/").append(year));
    }

    @Override
    public void onClick(View v) {
        Calendar calendar = Calendar.getInstance(TimeZone.getDefault());
        DatePickerDialog dialog = new DatePickerDialog(getContext(), this, calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH));
        dialog.show();
    }
}

然后在XML中使用它…

            <*.*.*.EditTextDP
                android:id="@+id/c1_dob_hm"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:background="@drawable/round_edittext_white"
                android:ems="10"
                android:padding="8dp">

            </*.*.*.EditTextDP>

使用@DrunkenDaddy扩展函数，至少在我的情况下(以编程方式创建EditText)，它在第一次单击时显示键盘，然后在第二次单击时显示日期选择器。

显然，将isFocusable和isFocusableInTouchMode设置为false是无关紧要的，因为第一次点击总是被EditText解释为焦点变化。因此，当EditText获得焦点时，我必须触发单击。现在它像预期的那样工作:第一次点击它直接打开日期选择器，而不是键盘(感谢设置showSoftInputOnFocus为false):

fun EditText.transformIntoDatePicker(context: Context, format: String = "dd/MM/yyyy", maxDate: Date? = null) {
    isClickable = true
    showSoftInputOnFocus = false
    isCursorVisible = false

    setOnFocusChangeListener { _, hasFocus ->  if (hasFocus) callOnClick()}

    val myCalendar = Calendar.getInstance()
    val datePickerOnDataSetListener =
        DatePickerDialog.OnDateSetListener { _, year, monthOfYear, dayOfMonth ->
            myCalendar.set(Calendar.YEAR, year)
            myCalendar.set(Calendar.MONTH, monthOfYear)
            myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth)
            val sdf = SimpleDateFormat(format, Locale.getDefault())
            setText(sdf.format(myCalendar.time))
    }

    setOnClickListener {
        DatePickerDialog(
             context, datePickerOnDataSetListener, 
             myCalendar.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
             myCalendar.get(Calendar.DAY_OF_MONTH)
        ).run {
            maxDate?.time?.also { datePicker.maxDate = it }
            show()
    }
}

# 1。我想显示一个datepicker与当前日期预选(我使用butterknife注入)

  @OnClick(R.id.your_view) public void onClickYourView() {

    final 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);
        String myFormat = "dd MMMM yyyy"; // your format
        SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.getDefault());

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

    };
    new DatePickerDialog(mContext, date, myCalendar.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH), myCalendar.get(Calendar.DAY_OF_MONTH)).show();

  }

2. 如果您想预选日期，请将最后一部分替换为

new DatePickerDialog(mContext, date, 1990, 0, 1).show();

然后你可以使用myCalendar变量或直接在视图上的文本来获取它。

把这4行放在(EditText, AppCompatEditText)上。它不会显示键盘。然后在clicklistener上，你可以显示datePicker

android:clickable="false" 
   android:cursorVisible="false" 
   android:focusable="false" 
   android:focusableInTouchMode="false"

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
    }
}
