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。

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();
   }
}

public class DatePickerActivity extends AppCompatActivity {
    Button button;
    static TextView textView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        button= (Button) findViewById(R.id.btn_click);
        textView= (TextView) findViewById(R.id.txt_date);



        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                DialogFragment newFragment=new DatePickerFragment();
                newFragment.show(getFragmentManager(), "datepicker");
            }
        });

    }

    public class DatePickerFragment extends DialogFragment implements    DatePickerDialog.OnDateSetListener{
        @Override
        public void onDateSet(DatePicker view, int year, int monthOfYear, int  day) {
            String years=""+year;
            String months=""+(monthOfYear+1);
            String days=""+day;
            if(monthOfYear>=0 && monthOfYear<9){
                months="0"+(monthOfYear+1);
            }
            if(day>0 && day<10){
                days="0"+day;

            }
            textView.setText(days+"/"+months+"/"+years);


        }

        @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);
            DatePickerDialog datePickerDialog=null;
            datePickerDialog=new DatePickerDialog(getActivity(), this, year,  month, day);

            return datePickerDialog;
        }

    }

}

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()));
        }
    };
}

/**
 * Return new DatePickerDialog for field
 * @param context
 * @return
 */
private DatePickerDialog getDatePickerDialog(Context context) {
    return new DatePickerDialog(context, getOnDateSetListener(), calendar
            .get(Calendar.YEAR), calendar.get(Calendar.MONTH),

}

}

用法:

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

使用数据绑定:

<EditText
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:focusable="false"
  android:onClick="@{() -> viewModel.onDateEditTextClicked()}"
  android:hint="@string/hint_date"
  android:imeOptions="actionDone"
  android:inputType="none"
  android:maxLines="1"
  android:text="@={viewModel.filterDate}" />

(参见focusable, inputType和onClick)

在视图模型:

public void onDateEditTextClicked() {
    // do something
}

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();
                }
            });
