我找不到明确的答案。

在android片段中实现2个日期选择器的最简单方法是什么？

只需要用户点击每个按钮时的对话框以及用户选择一个按钮时的返回值。

Answer 1

试试这个，

按钮点击：

int select_date = 1; 


    et_date1.setOnClickListener(new View.OnClickListener() { 
     @Override 
      select_date = 1; 
      showDatePickerDialog(); 
     } 
    }); 

    et_date2.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      select_date = 2; 
      showDatePickerDialog(); 
     } 
    }); 

showDatePickerDialog：

private void showDatePickerDialog() { 
    DialogFragment newFragment = new DatePickerFragment(); 
    newFragment.show(getChildFragmentManager(), "datePicker"); 
    } 

DatePickerFragment：

public static class DatePickerFragment extends DialogFragment implements 
     DatePickerDialog.OnDateSetListener { 

    @NonNull 
    @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 
     DatePickerDialog date_picker = new DatePickerDialog(getActivity(), this, year, month, day); 

     return date_picker; 
    } 

    public void onDateSet(DatePicker view, int year, int month, int day) { 
     // Do something with the date chosen by the user 
     String str_date = day + "/" + (month + 1) + "/" + year; 
     if (select_date == 1) { 
      et_date1.setText(str_date); 
     } else { 
      et_date2.setText(str_date); 
     } 
     select_date = 0; 
    } 
}

你应该总是提供您的代码行，使它更轻松让每个人都知道你在找什么，以及如何正确地帮助你。

但是，这里有一个简单的方法来调用，它会产生一个datepicker：

private void showDatePickerDialog(final EditText view) { 
    /** 
    * @author Mohammed Al-Safwan 
    * **/ 
    final Calendar c = Calendar.getInstance(); 
    int mYear = c.get(Calendar.YEAR); // current year 
    int mMonth = c.get(Calendar.MONTH); // current month 
    int mDay = c.get(Calendar.DAY_OF_MONTH); // current day 

    DatePickerDialog datePickerDialog = new DatePickerDialog(mContext, new DatePickerDialog.OnDateSetListener() { 
     /** 
     * 
     * @param year selected year. 
     * @param month selected month. 
     * @param day selected day. 
     * **/ 
     @Override 
     public void onDateSet(DatePicker datePicker, int year, int month, int day) { 

     } 


    }, mYear, mMonth, mDay); 

    // finally, show your dialog 
    datePickerDialog.show(); 
}
