我使用Fragment,它是片段的实例,而不是DialogFragment.
我做过google的大部分搜索结果显示如何使用DialogFragment来拥有DatePicker.
这在我的情况下不起作用,因为Fragment和DialogFragment的类型不匹配
任何一个例子或想法都是有帮助的
public class CreateReportFragment extends Fragment {
public CreateReportFragment(){}
public View onCreateView(LayoutInflater inflater,ViewGroup container,Bundle savedInstanceState)
{
rootView = inflater.inflate(R.layout.activity_create_report,container,false);
initViews();
return rootView;
}
private void initViews()
{
final Calendar c = Calendar.getInstance();
year = c.get(Calendar.YEAR);
month = c.get(Calendar.MONTH);
day = c.get(Calendar.DAY_OF_MONTH);
editTextDate.setText(new StringBuilder()
// Month is 0 based,just add 1
.append(year)
.append("-")
.append(month + 1)
.append("-").append(day));
buttonDate = (Button)rootView.findViewById(R.id.buttonDate);
}
如何在片段中实现DatePicker？
解决方法
使用DialogFragment
如果我猜对了,你想要点击buttonDate显示一个DatePicker
http://developer.android.com/guide/topics/ui/controls/pickers.html
点击按钮
DialogFragment picker = new DatePickerFragment(); picker.show(getFragmentManager(),"datePicker");
DatePickerFragment.java
public 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) {
Calendar c = Calendar.getInstance();
c.set(year,day);
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
String formattedDate = sdf.format(c.getTime());
}
}
