我从 SherlockFragmentActivity 创建了一个 SherlockDialogFragment..
这是我到目前为止所做的::
DatePickerFragment newFragment = DatePickerFragment.newInstance(ReportDisplayActivity.this);
newFragment.show(getSupportFragmentManager(), "dialog");
SherlockDialogFragment
public class DatePickerFragment extends SherlockDialogFragment implements android.view.View.OnClickListener
{
private Button btnOk;
private TextView txtFromDate;
private TextView txtToDate;
private int setFromYear;
private int setFromMonth;
private int setFromDay;
private int setToYear;
private int setToMonth;
private int setToDay;
private final static int DIALOG_FROM_DATE_PICKER = 0;
private final static int DIALOG_TO_DATE_PICKER = 1;
private static Context context;
public DatePickerFragment() {
}
public static DatePickerFragment newInstance(Context ctx) {
DatePickerFragment frag = new DatePickerFragment();
Bundle args = new Bundle();
//args.putInt("title", title);
frag.setArguments(args);
context=ctx;
return frag;
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState)
{
View rootView = inflater.inflate(R.layout.temp, container, false);
txtFromDate=(TextView)rootView.findViewById(R.id.dialog_fromDate);
txtToDate=(TextView)rootView.findViewById(R.id.dialog_toDate);
btnOk=(Button)rootView.findViewById(R.id.btn_ok);
btnOk.setOnClickListener(this);
txtFromDate.setOnClickListener(this);
txtToDate.setOnClickListener(this);
Calendar today = Calendar.getInstance();
setFromYear = today.get(Calendar.YEAR);
setFromMonth = today.get(Calendar.MONDAY);
setFromDay = today.get(Calendar.DAY_OF_MONTH);
setToYear = today.get(Calendar.YEAR);
setToMonth = today.get(Calendar.MONDAY);
setToDay = today.get(Calendar.DAY_OF_MONTH);
return rootView;
}
//@Override
protected Dialog onCreateDialog(int id)
{
switch(id)
{
case DIALOG_FROM_DATE_PICKER:
return new DatePickerDialog(context, mDateFromSetListener, setFromYear, setFromMonth, setFromDay);
case DIALOG_TO_DATE_PICKER:
return new DatePickerDialog(context, mDateToSetListener, setToYear, setToMonth, setToDay);
}
return null;
}
private DatePickerDialog.OnDateSetListener mDateFromSetListener = new DatePickerDialog.OnDateSetListener(){
@Override
public void onDateSet(android.widget.DatePicker view, int year, int month, int day) {
setFromYear = year;
setFromMonth = month;
setFromDay = day;
//returnDate();
txtFromDate.setText(setFromDay+("-")+setFromMonth+("-")+setFromYear);
}
};
private DatePickerDialog.OnDateSetListener mDateToSetListener = new DatePickerDialog.OnDateSetListener(){
@Override
public void onDateSet(android.widget.DatePicker view, int year, int month, int day) {
setToYear = year;
setToMonth = month;
setToDay = day;
txtFromDate.setText(setToDay+("-")+setToMonth+("-")+setToYear);
//returnDate();
}
};
public void onClick(View v)
{
switch (v.getId()) {
case R.id.btn_ok:
Toast.makeText(context,"Button ok",Toast.LENGTH_SHORT).show();
break;
case R.id.dialog_fromDate :
Toast.makeText(context,"From Date",Toast.LENGTH_SHORT).show();
((Activity) context).showDialog(DIALOG_FROM_DATE_PICKER);
break;
case R.id.dialog_toDate :
Toast.makeText(context,"To Date",Toast.LENGTH_SHORT).show();
((Activity) context).showDialog(DIALOG_TO_DATE_PICKER);
break;
default:
break;
}
}
}
我无法从 SherlockDialogFragment 打开 Datepicker 对话框。我无法在我的实现中找到问题所在。
如果我使用 Activity 而不是 SherlockDialogFragment 那么它工作正常。

我可以像这样弹出对话框，但是当我点击文本“从日期选择”或“选择到日期”(从我想显示日期选择器对话框的地方)时，日期选择器对话框不显示。

style.xml 与您的代码相同。
我在您的代码中发现您是通过以下语句获取月份 setFromMonth = today.get(Calendar.MONDAY); 或 setToMonth = today.get(Calendar.MONDAY); 。我相信你做错了。我还通过编写一个通用的 mDateSetListener 监听器来最小化您的代码。另请记住，Calendar.MONTH 对 1 月返回 0，因为它的索引以 0 开头。在将月份值设置为相应的 TextView 之前，我在监听器中添加了 +1。
关于android - 从对话框调用 onCreateDialog()，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/20879488/
