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>

我已经尝试了所有建议的方法，但它们都有各自的问题。

在我看来，最好的解决方案是使用如下的框架布局:

<FrameLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content" >

            <EditText
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                .... />

            <View
                android:id="@+id/invisible_click_watcher"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:clickable="true" />

</FrameLayout>

然后添加DatePickerDialog代码，这个代码在@Android的回答中写得很漂亮。

我对沙玛林的解决方案。基于Linh的MvvmCross的Android:

public class DatePickerEditText : EditText, DatePickerDialog.IOnDateSetListener
{
    IDisposable _clickSubscription;

    public override bool Clickable => true;

    protected DatePickerEditText(IntPtr javaReference, JniHandleOwnership transfer)
        : base(javaReference, transfer)
        => Init();

    public DatePickerEditText(Context context) : base(context)
        => Init();

    public DatePickerEditText(Context context, IAttributeSet attrs) 
        : base(context, attrs)
        => Init();

    public DatePickerEditText(Context context, IAttributeSet attrs, int defStyleAttr) 
        : base(context, attrs, defStyleAttr)
        => Init();

    public DatePickerEditText(Context context, IAttributeSet attrs, int defStyleAttr, int defStyleRes) 
        : base(context, attrs, defStyleAttr, defStyleRes)
        => Init();

    protected override void Dispose(bool disposing)
    {
        if (disposing)
        {
            _clickSubscription?.Dispose();
            _clickSubscription = null;
        }

        base.Dispose(disposing);
    }

    public void OnDateSet(DatePicker view, int year, int month, int dayOfMonth)
        => Text = view.DateTime.ToString("d", CultureInfo.CurrentUICulture);

    void Init()
    {
        SetFocusable(ViewFocusability.NotFocusable);
        _clickSubscription = this.WeakSubscribe(nameof(Click), OnClick);
    }

    void OnClick(object sender, EventArgs e)
    {
        var date = DateTime.Today;
        try
        {
            date = DateTime.Parse(Text, CultureInfo.CurrentUICulture);
        }
        catch (Exception ex)
        {
            System.Diagnostics.Debug.WriteLine(ex);
        }

        var dialog = new DatePickerDialog(Context,
                                          this,
                                          date.Year,
                                          date.Month,
                                          date.Day);
        dialog.Show();
    }
}

来杯香草沙玛林。Android版本只需将WeakSubscribe替换为EditText的Click事件的常规订阅，不要忘记在Dispose方法覆盖中取消订阅。

class MyClass implements OnClickListener, OnDateSetListener {   
   EditText editText;
   this.editText = (EditText) findViewById(R.id.editText);
   this.editText.setOnClickListener(this);
   @Override
   public void onClick(View v) {

       DatePickerDialog dialog = new DatePickerDialog(this, this, 2013, 2, 18);
       dialog.show();
   }
   @Override
   public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
       // this.editText.setText();
   }
}

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:)

下面是一个针对懒人的Kotlin扩展函数:

fun EditText.transformIntoDatePicker(context: Context, format: String, maxDate: Date? = null) {
    isFocusableInTouchMode = false
    isClickable = true
    isFocusable = false

    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.UK)
            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()
        }
    }
}

用法:

在活动:

editText.transformIntoDatePicker(this, "MM/dd/yyyy")
editText.transformIntoDatePicker(this, "MM/dd/yyyy", Date())

在片段:

editText.transformIntoDatePicker(requireContext(), "MM/dd/yyyy")
editText.transformIntoDatePicker(requireContext(), "MM/dd/yyyy", Date())
