我的类为show DatePicker。我可以使用EditText, TextView或按钮

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.Date;
import java.util.TimeZone;

public class TextViewDatePicker
        implements View.OnClickListener, DatePickerDialog.OnDateSetListener {
    public static final String DATE_SERVER_PATTERN = "yyyy-MM-dd";
    private DatePickerDialog mDatePickerDialog;
    private TextView mView;
    private Context mContext;
    private long mMinDate;
    private long mMaxDate;

    public TextViewDatePicker(Context context, TextView view) {
        this(context, view, 0, 0);
    }

    public TextViewDatePicker(Context context, TextView view, long minDate, long maxDate) {
        mView = view;
        mView.setOnClickListener(this);
        mView.setFocusable(false);

        mContext = context;
        mMinDate = minDate;
        mMaxDate = maxDate;
    }

    @Override
    public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
        Calendar calendar = Calendar.getInstance();
        calendar.set(Calendar.YEAR, year);
        calendar.set(Calendar.MONTH, monthOfYear);
        calendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
        Date date = calendar.getTime();

        SimpleDateFormat formatter = new SimpleDateFormat(DATE_SERVER_PATTERN);
        mView.setText(formatter.format(date));
    }

    @Override
    public void onClick(View v) {
        Calendar calendar = Calendar.getInstance(TimeZone.getDefault());
        mDatePickerDialog = new DatePickerDialog(mContext, this, calendar.get(Calendar.YEAR),
                calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH));
        if (mMinDate != 0) {
            mDatePickerDialog.getDatePicker().setMinDate(mMinDate);
        }
        if (mMaxDate != 0) {
            mDatePickerDialog.getDatePicker().setMaxDate(mMaxDate);
        }
        mDatePickerDialog.show();
    }

    public DatePickerDialog getDatePickerDialog() {
        return mDatePickerDialog;
    }

    public void setMinDate(long minDate) {
        mMinDate = minDate;
    }

    public void setMaxDate(long maxDate) {
        mMaxDate = maxDate;
    }
}

使用

EditText myEditText = findViewById(R.id.myEditText);
TextViewDatePicker editTextDatePicker = new TextViewDatePicker(context, myEditText, minDate, maxDate);
//TextViewDatePicker editTextDatePicker = new TextViewDatePicker(context, myEditText); //without min date, max date

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();
                }
            });

在XML文件中试试这个:

<EditText
    android:id="@+id/Birthday"
    custom:font="@string/font_avenir_book"
    android:clickable="false" 
    android:cursorVisible="false" 
    android:focusable="false" 
    android:focusableInTouchMode="false"
    android:hint="@string/birthday"/>

在Java文件中是这样的:

public class MainActivity extends AppCompatActivity {
    final Calendar myCalendar= Calendar.getInstance();
    EditText editText;
    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        editText=(EditText) findViewById(R.id.BirthDate);
        DatePickerDialog.OnDateSetListener date =new DatePickerDialog.OnDateSetListener() {
            @Override
            public void onDateSet(DatePicker view, int year, int month, int day) {
                myCalendar.set(Calendar.YEAR, year);
                myCalendar.set(Calendar.MONTH,month);
                myCalendar.set(Calendar.DAY_OF_MONTH,day);
                updateLabel();
            }
        };
        editText.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                new DatePickerDialog(MainActivity.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";
        SimpleDateFormat dateFormat=new SimpleDateFormat(myFormat, Locale.US);
        editText.setText(dateFormat.format(myCalendar.getTime()));
    }
}

在EditText的xml文件中添加android:focusable="false"以允许单个触摸。

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())

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"

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();
   }
}
