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。

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函数下调用这个类:
EditText editTextFromDate = (EditText) findViewById(R.id.editTextFromDate);
setDate fromDate = new setDate(editTextFromDate, this);
其他回答
日期选择对话框
Calendar c=Calendar.getInstance();
Integer month=c.get(Calendar.MONTH);
Integer day=c.get(Calendar.DAY_OF_MONTH);
Integer year=c.get(Calendar.YEAR);
DatePickerDialog datePickerDialog =new DatePickerDialog(Expenture_Activity.this, new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
et_from.setText(dayOfMonth+"/"+month+"/"+year);
}
},year,month,day);
datePickerDialog.show();
试试这个
btn=(Button)findViewById(R.id.chs);
final Dialog dialog = new Dialog(MainActivity.this);
dialog.setCanceledOnTouchOutside(true);
btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
dialog.setContentView(R.layout.datepickerdialog);
dp=(DatePicker) dialog.findViewById(R.id.btp);
dialog.show();
ok=(Button)dialog.findViewById(R.id.btn1);
ok.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
dialog.dismiss();
}
});
}
});
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();
}
});
选中的答案不太适合我,因为我必须点击EditText框一次,然后在OnClickListener启动之前再次点击它。我能够通过用OnTouchListener替换OnClickListener来修复这个问题,以防有人遇到类似的问题,下面是我的代码看起来是什么样的:
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()));
}
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;
}
}
}
