我使用的是扩展线性布局而不是从程序上显示的活动。
公共类displaydatepicker扩展了linearlayout{
这里是我想通过点击按钮getdate来显示日期选择器；并且
在文本视图上显示。}
Date = Calendar.getInstance();
btnnTest.setOnClickListener(new Button.OnClickListener() {
@Override
public void onClick(View v) {
showDateDialog(etTest, Date);
}
});
现在展开上面的函数ShowDateDialog，它调用成功但没有显示DatePicker对话框；
protected void showDateDialog(EditText etLocationTest2, Calendar date2) {
Log.i("", "Date showDateDialog ");
((Activity) getContext()).showDialog(DATE_DIALOG_ID);
}
In here Could not display Date picker Dialog box, why? i think showDialog box could not call DATE_DIALOG_ID,
so how to call this, any idea?
此处显示对话框的截止日期：
protected Dialog onCreateDialog(int id) {
switch (id) {
case DATE_DIALOG_ID:
// set date picker as current date
return new DatePickerDialog(getContext(), datePickerListener, year, month,day);
return null;
}
private DatePickerDialog.OnDateSetListener datePickerListener = new DatePickerDialog.OnDateSetListener() {
// when dialog box is closed, below method will be called.
public void onDateSet(DatePicker view, int selectedYear,
int selectedMonth, int selectedDay) {
year = selectedYear;
month = selectedMonth;
day = selectedDay;
// set selected date into textview
tvDisplayDate.setText(new StringBuilder().append(month + 1)
.append("-").append(day).append("-").append(year)
.append(" "));
}
我希望你理解我的问题，并等待任何回应。
最佳答案
这对我有效。希望对你也有帮助
我已经在下面添加了实现此功能的所有代码
将其保存在扩展linearlayout的类中
DatePopListener mDatePopListener;
private DatePickerDialog datePickerDialog;
private SimpleDateFormat dateFormatter;
创建一个构造函数，从中获取初始化该类的上下文。
使用的代码对我来说很好。
class displayDatePicker extends linearlayout{
DatePopListener mDatePopListener;
EditText edittext;
TextBox label;
private DatePickerDialog datePickerDialog;
private SimpleDateFormat dateFormatter;
public displayDatePicker(Context context,String labelText){
dateFormatter = new SimpleDateFormat("dd-MM-yyyy", Locale.US);
Calendar newCalendar = Calendar.getInstance();
label.setText(labelText);
this.addView(label);
this.addView(txtBox);
txtBox.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
datePickerDialog.show();
}
});
datePickerDialog = new DatePickerDialog(getContext(), new DatePickerDialog.OnDateSetListener() {
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
Calendar newDate = Calendar.getInstance();
newDate.set(year, monthOfYear, dayOfMonth);
txtBox.setText(dateFormatter.format(newDate.getTime()));
}
},newCalendar.get(Calendar.YEAR), newCalendar.get(Calendar.MONTH), newCalendar.get(Calendar.DAY_OF_MONTH));
}
//Now you can do your task here whatever as the date will be available in txtBox
//Enter your code as your requirements
}
