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。
当前回答
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();
其他回答
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。
用这个简单的技巧来做吧:
步骤1:创建一个片段对话框
public class DatePickerFragmentDialog extends DialogFragment {
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
Calendar c = Calendar.getInstance();
int year = c.get(Calendar.YEAR);
int month = c.get(Calendar.MONTH);
int day = c.get(Calendar.DAY_OF_MONTH);
return new DatePickerDialog(getActivity(), (DatePickerDialog.OnDateSetListener) getActivity(), year, month, day);
}
}
第二步:在必要的活动中遵循这一点
该活动必须实现:DatePickerDialog。OnDateSetListener 在按钮上设置onClickListener: DialogFragment datePicker = new DatePickerFragmentDialog(); datePicker.show(getSupportFragmentManager(), "自定义日期选择器");
步骤3:覆盖OnDateSetListener
public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.YEAR, year);
calendar.set(Calendar.MONTH, month);
calendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
@SuppressLint("SimpleDateFormat") DateFormat dateFormat = new
SimpleDateFormat("MM/dd/yyyy");
String currentDateString = dateFormat.format(calendar.getTime());
tvPaymentDate.setText(currentDateString);
}
因此,我们可以使用任何格式的日期:)
selectDate.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
DatePickerDialog mdiDialog =new DatePickerDialog(mContext,new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
Toast.makeText(getApplicationContext(),year+ " "+monthOfYear+" "+dayOfMonth,Toast.LENGTH_LONG).show();
}
}, year, month, date);
mdiDialog.show();
}
});
editText。setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(final View v) {
final Calendar c = Calendar.getInstance();
mYear = c.get(Calendar.YEAR);
mMonth = c.get(Calendar.MONTH);
mDay = c.get(Calendar.DAY_OF_MONTH);
final DatePickerDialog datePickerDialog = new DatePickerDialog(getContext(),
new DatePickerDialog.OnDateSetListener() {
String fmonth, fDate;
int month;
@Override
public void onDateSet(DatePicker view, int year,
int monthOfYear, int dayOfMonth) {
try {
if (monthOfYear < 10 && dayOfMonth < 10) {
fmonth = "0" + monthOfYear;
month = Integer.parseInt(fmonth) + 1;
fDate = "0" + dayOfMonth;
String paddedMonth = String.format("%02d", month);
editText.setText(fDate + "/" + paddedMonth + "/" + year);
} else {
fmonth = "0" + monthOfYear;
month = Integer.parseInt(fmonth) + 1;
String paddedMonth = String.format("%02d", month);
editText.setText(dayOfMonth + "/" + paddedMonth + "/" + year);
}
} catch (Exception e) {
e.printStackTrace();
}
}
}, mYear, mMonth, mDay);
datePickerDialog.getDatePicker().setMaxDate(System.currentTimeMillis());
datePickerDialog.show();
}
});
我不能得到这些工作中的任何人,所以将添加我的一个,以防它有帮助。
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(" "));
}
}
还有其他书里没有提到的东西。确保将以下内容放在EditText xml上。
android:focusable="false"
否则,就像在我的例子中,键盘会不断弹出。
