Datepicker:如何在单击edittext时弹出datepicker

Question

我想显示datepicker弹出窗口.我找到了一些例子,但我没有得到正确的答案.我有一个edittext,我希望当我点击edittext时,应该弹出datepicker对话框,设置日期后,日期应该以dd/mm/yyyy格式显示在edittext中.PLease为我提供示例代码或良好的链接.

Answer 1

在XML文件中尝试:

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

现在在Java文件中:

final Calendar myCalendar = Calendar.getInstance();

EditText edittext= (EditText) findViewById(R.id.Birthday);
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);
        updateLabel();
    }

};

edittext.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub
        new DatePickerDialog(classname.this, date, myCalendar
                .get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
                myCalendar.get(Calendar.DAY_OF_MONTH)).show();
    }
});

现在在上面的活动中添加方法.

private void updateLabel() {
    String myFormat = "MM/dd/yy"; //In which you need put here
    SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.US);

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

android:focusable="false"在EditText的xml文件中添加以允许单次触摸.

Answer 2

无法让这些人工作,所以将添加我的一个只是在它有帮助的情况下.

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(" "));
}
}

也是其他人没有提到的东西.确保将以下内容放在EditText xml上.

android:focusable="false"

否则就像我的情况一样,键盘会不断弹出.希望这有助于某人

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();
   }
}

Answer 4

这是一个 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：

在活动中：

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

在片段中：

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

还有另一种更好的可重用方式:

创建一个类:

class setDate implements OnFocusChangeListener, OnDateSetListener {   

       private EditText editText;
       private Calendar myCalendar;

       public setDate(EditText editText, Context ctx){
           this.editText = editText;
           this.editText.setOnFocusChangeListener(this);
           myCalendar = Calendar.getInstance();
       }

       @Override
       public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth)     {
           // this.editText.setText();

            String myFormat = "MMM dd, yyyy"; //In which you need put here
            SimpleDateFormat sdformat = new SimpleDateFormat(myFormat, Locale.US);
            myCalendar.set(Calendar.YEAR, year);
            myCalendar.set(Calendar.MONTH, monthOfYear);
            myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);

            editText.setText(sdformat.format(myCalendar.getTime()));

       }

        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            // TODO Auto-generated method stub
            if(hasFocus){
             new DatePickerDialog(ctx, this, myCalendar
                       .get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
                       myCalendar.get(Calendar.DAY_OF_MONTH)).show();
            }
        }

    }

然后在onCreate函数下调用此类:

    EditText editTextFromDate = (EditText) findViewById(R.id.editTextFromDate);
    setDate fromDate = new setDate(editTextFromDate, this);

<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"/>

JAVA文件

import android.app.DatePickerDialog;
import android.app.TimePickerDialog;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.DatePicker;
import android.widget.EditText;
import android.widget.TimePicker;

import java.util.Calendar;

public class MainActivity extends AppCompatActivity implements View.OnClickListener {

    EditText selectDate,selectTime;
    private int mYear, mMonth, mDay, mHour, mMinute;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        selectDate=(EditText)findViewById(R.id.date);
        selectTime=(EditText)findViewById(R.id.time);

        selectDate.setOnClickListener(this);
        selectTime.setOnClickListener(this);




    }

    @Override
    public void onClick(View view) {

        if (view == selectDate) {
            final Calendar c = Calendar.getInstance();
            mYear = c.get(Calendar.YEAR);
            mMonth = c.get(Calendar.MONTH);
            mDay = c.get(Calendar.DAY_OF_MONTH);


            DatePickerDialog datePickerDialog = new DatePickerDialog(this,
                    new DatePickerDialog.OnDateSetListener() {

                        @Override
                        public void onDateSet(DatePicker view, int year,
                                              int monthOfYear, int dayOfMonth) {

                            selectDate.setText(dayOfMonth + "-" + (monthOfYear + 1) + "-" + year);

                        }
                    }, mYear, mMonth, mDay);
            datePickerDialog.show();
        }
        if (view == selectTime) {

            // Get Current Time
            final Calendar c = Calendar.getInstance();
            mHour = c.get(Calendar.HOUR_OF_DAY);
            mMinute = c.get(Calendar.MINUTE);

            // Launch Time Picker Dialog
            TimePickerDialog timePickerDialog = new TimePickerDialog(this,
                    new TimePickerDialog.OnTimeSetListener() {

                        @Override
                        public void onTimeSet(TimePicker view, int hourOfDay,
                                              int minute) {

                            selectTime.setText(hourOfDay + ":" + minute);
                        }
                    }, mHour, mMinute, false);
            timePickerDialog.show();
        }
    }
}

Answer 7

这就是我这样做的方法:与所选答案类似,但使用静态对话框类,因此它更可重用,并且还使用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");
            }
        }
    });

和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
    }
}

Answer 8

选择的答案对我来说并不适用,因为我必须点击EditText框一次,然后在OnClickListener触发之前再次点击它.我能够通过用OnTouchListener替换OnClickListener来解决这个问题,以防万一有人遇到类似的问题,这就是我的代码:

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);
        updateLabel();
    }

};
edittext.setOnTouchListener(new View.OnTouchListener() {

    @Override
    public void onTouch(View v, MotionEvent event) {
        if(event.getAction() == MotionEvent.ACTION_DOWN) {
            new DatePickerDialog(classname.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"; //In which you need put here
    SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.US);

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

Answer 9

#1.我想显示一个当前日期为预选的日期选择器(我使用黄油刀进行注射)

  @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.如果要预先选择日期,请将最后一部分替换为

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

那么您可以使用myCalendar变量或直接使用视图中的文本来获取它.
