EditText text = (EditText) findViewById(R.id.editText);

    text.setOnClickListener(new OnClickListener(){
       @RequiresApi(api = Build.VERSION_CODES.N)
       @Override
       public void onClick(View view) {

             DatePickerDialog datePickerDialog = new DatePickerDialog(this, new DatePickerDialog.OnDateSetListener() {
               @Override
               public void onDateSet(DatePicker datePicker, int i, int i1, int i2) {
                   String date = i2 + "/" + (++i1) + "/" + i;
                   text.setText(date);
                }
        },year,month,date);
       }
    });  

    datePickerDialog.show();

您还可以通过这些语句设置最小日期和最大日期。

   datepickerDialoge.getDatepicker().setMinDate(long Date);

   datepickerDialoge.getDatepicker().setMaxDate(long Date);

注意:在datepickerDialog.show()之前添加这些行;声明 你会得到这样的日期=12/2/2017。

我希望我的回答能有所帮助。

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。

<EditText
    android:id="@+id/date"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:ems="10"
    android:hint="DD/MM/YYYY"
    android:inputType="date"
    android:focusable="false"/>

<EditText
    android:id="@+id/time"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:hint="00:00"
    android:inputType="time"
    android:focusable="false"/>

}

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()
    }
}

import android.app.DatePickerDialog;
import android.content.Context;
import android.view.View;
import android.widget.DatePicker;
import android.widget.TextView;

import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Locale;

public class DatePickerHelper {

private final Calendar calendar = Calendar.getInstance();
private final String dateFormat = "MM/dd/yy";
private TextView textView = null;

public DatePickerHelper(final Context context, TextView textView) {
    this.textView = textView;

    // Setup on click listener if the TextView is not null
    if (textView != null) {
        textView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                getDatePickerDialog(context).show();
            }
        });
    }
}

/**
 * Return a new date picker listener tied to the specified TextView field
 * @return
 */
private DatePickerDialog.OnDateSetListener getOnDateSetListener() {
    return new DatePickerDialog.OnDateSetListener() {
        @Override
        public void onDateSet(DatePicker view, int year, int monthOfYear,
                              int dayOfMonth) {
            calendar.set(Calendar.YEAR, year);
            calendar.set(Calendar.MONTH, monthOfYear);
            calendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);

            SimpleDateFormat sdf = new SimpleDateFormat(dateFormat, Locale.US);
            textView.setText(sdf.format(calendar.getTime()));
        }
    };
}

/**

            .get(Calendar.YEAR), calendar.get(Calendar.MONTH),

}

}

用法:

  DatePickerHelper assessmentDueDateHelper = new DatePickerHelper(AssessmentsDetailActivity.this,
            (TextView) findViewById(R.id.assessmentDueDateEditText));

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。
