我想显示日期选择器弹出窗口。我找到了一些例子,但我没有得到正确的。我有一个edittext,我希望当我点击edittext时,datepicker对话框应该弹出,设置日期后,日期应该显示在edittext在dd/mm/yyyy格式。请为我提供示例代码或良好的链接。

Kotlin端口,调用setDatePicker函数
private fun setDatePicker(dateEditText: EditText) {
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)
updateLabel(myCalendar, dateEditText)
}
dateEditText.setOnClickListener {
DatePickerDialog(this@YourActivityName, datePickerOnDataSetListener, myCalendar
.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
myCalendar.get(Calendar.DAY_OF_MONTH)).show()
}
}
private fun updateLabel(myCalendar: Calendar, dateEditText: EditText) {
val myFormat: String = "dd-MMM-yyyy"
val sdf = SimpleDateFormat(myFormat, Locale.UK)
dateEditText.setText(sdf.format(myCalendar.time))
}

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"
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
如果你需要一个单一的功能,所有的活动,当调用将打开日期选择器,然后返回我选择的日期,然后为所有创建一个接口
public interface OnDatePickerLitionarCallBack {
void DatePicker(String selectedDate);
}
然后在活动中调用接口
public class MapsActivity extends FragmentActivity implements OnDatePickerLitionarCallBack {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps);
findViewById(R.id.date_pick).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
date_Picker(MapsActivity.this,MapsActivity.this);
}
});
}
@Override
public void DatePicker(String selectedDate) {
}
}
实现接口后,创建一个公共类用于访问任何活动或片段
public class Commons{
public static void date_Picker(Context context, OnDatePickerLitionarCallBack onDatePickerLitionarCallBack) {
final java.util.Calendar myCalendar = java.util.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(java.util.Calendar.YEAR, year);
myCalendar.set(java.util.Calendar.MONTH, monthOfYear);
myCalendar.set(java.util.Calendar.DAY_OF_MONTH, dayOfMonth);
String myFormat = "dd,MMM yyyy"; //In which you need put here
java.text.SimpleDateFormat sdf = new java.text.SimpleDateFormat(myFormat, Locale.US);
onDatePickerLitionarCallBack.DatePicker(sdf.format(myCalendar.getTime()));
}
};
DatePickerDialog datePickerDialog = new DatePickerDialog(context, date, myCalendar
.get(java.util.Calendar.YEAR), myCalendar.get(java.util.Calendar.MONTH),
myCalendar.get(java.util.Calendar.DAY_OF_MONTH));
datePickerDialog.show();
}
}
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>
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();
}
});
