Android wie man DatePicker in Fragment zeigt?

Question

Ich bin neu auf Android Fragmente und ich möchte wissen, dass, wie kann ich DatePicker in einfache Fragment und nicht eine FragmentActivity zeigen oder implementieren.

Zum Beispiel meines Klassenname ist:

public class FragmentAddCard extends Fragment { 
} 

Dank.

Answer 1

In Ihrer Taste, um die DateFragment klicken nennen wie diese

dob.setOnClickListener(new View.OnClickListener() { 

     @Override 
     public void onClick(View arg0) { 

      DialogFragment newFragment = new SelectDateFragment(); 
      newFragment.show(getFragmentManager(), "DatePicker"); 

     } 
    }); 

Hier ist der Code-Snippet für DateFragment

public class SelectDateFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener { 

     @Override 
     public Dialog onCreateDialog(Bundle savedInstanceState) { 
     final Calendar calendar = Calendar.getInstance(); 
     int yy = calendar.get(Calendar.YEAR); 
     int mm = calendar.get(Calendar.MONTH); 
     int dd = calendar.get(Calendar.DAY_OF_MONTH); 
     return new DatePickerDialog(getActivity(), this, yy, mm, dd); 
     } 

     public void onDateSet(DatePicker view, int yy, int mm, int dd) { 
      populateSetDate(yy, mm+1, dd); 
     } 
     public void populateSetDate(int year, int month, int day) { 
      dob.setText(month+"/"+day+"/"+year); 
      } 

    } 

Answer 2

Dies ist ein weiteres Beispiel:

Calendar cal = Calendar.getInstance(TimeZone.getDefault()); // Get current date 

// Create the DatePickerDialog instance 
DatePickerDialog datePicker = new DatePickerDialog(this, 
        R.style.AppBlackTheme, datePickerListener, 
        cal.get(Calendar.YEAR), 
             cal.get(Calendar.MONTH), 
        cal.get(Calendar.DAY_OF_MONTH)); 
      datePicker.setCancelable(false); 
      datePicker.setTitle("Select the date"); 
datePicker.show(); 

// Listener 
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) { 
     String year1 = String.valueOf(selectedYear); 
     String month1 = String.valueOf(selectedMonth + 1); 
     String day1 = String.valueOf(selectedDay); 
     TextView tvDt = (TextView) findViewById(R.id.tvDate); 
     tvDt.setText(day1 + "/" + month1 + "/" + year1); 

    } 
};

Zu allererst i kann sagen, dass die ausgewählte Antwort funktioniert. Es ist ein guter Ansatz. Aber wenn Sie MaterailDatePicker mit Fragment verwenden möchten. Ich habe eine Lösung gefunden. Versuchen Sie, für Set DatePicker in Fragment zu folgen.

Gradle

dependencies { 
    compile 'com.wdullaer:materialdatetimepicker:3.1.3' 
} 

DatePickerFragment

package com.wdullaer.datetimepickerexample; 

import android.app.Fragment; 
import android.graphics.Color; 
import android.os.Bundle; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.Button; 
import android.widget.CheckBox; 
import android.widget.TextView; 

import com.wdullaer.materialdatetimepicker.date.DatePickerDialog; 

import java.util.Calendar; 

/** 
* A simple {@link Fragment} subclass. 
*/ 
public class DatePickerFragment extends Fragment implements DatePickerDialog.OnDateSetListener { 

    private TextView dateTextView; 
    private CheckBox modeDarkDate; 
    private CheckBox modeCustomAccentDate; 
    private CheckBox vibrateDate; 
    private CheckBox dismissDate; 
    private CheckBox titleDate; 
    private CheckBox showYearFirst; 
    private CheckBox showVersion2; 
    private CheckBox limitSelectableDays; 
    private CheckBox highlightDays; 

    public DatePickerFragment() { 
     // Required empty public constructor 
    } 


    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
          Bundle savedInstanceState) { 
     View view = inflater.inflate(R.layout.datepicker_layout, container, false); 

     // Find our View instances 
     dateTextView = (TextView) view.findViewById(R.id.date_textview); 
     Button dateButton = (Button) view.findViewById(R.id.date_button); 
     modeDarkDate = (CheckBox) view.findViewById(R.id.mode_dark_date); 
     modeCustomAccentDate = (CheckBox) view.findViewById(R.id.mode_custom_accent_date); 
     vibrateDate = (CheckBox) view.findViewById(R.id.vibrate_date); 
     dismissDate = (CheckBox) view.findViewById(R.id.dismiss_date); 
     titleDate = (CheckBox) view.findViewById(R.id.title_date); 
     showYearFirst = (CheckBox) view.findViewById(R.id.show_year_first); 
     showVersion2 = (CheckBox) view.findViewById(R.id.show_version_2); 
     limitSelectableDays = (CheckBox) view.findViewById(R.id.limit_dates); 
     highlightDays = (CheckBox) view.findViewById(R.id.highlight_dates); 

     // Show a datepicker when the dateButton is clicked 
     dateButton.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       Calendar now = Calendar.getInstance(); 
       DatePickerDialog dpd = DatePickerDialog.newInstance(
         DatePickerFragment.this, 
         now.get(Calendar.YEAR), 
         now.get(Calendar.MONTH), 
         now.get(Calendar.DAY_OF_MONTH) 
       ); 
       dpd.setThemeDark(modeDarkDate.isChecked()); 
       dpd.vibrate(vibrateDate.isChecked()); 
       dpd.dismissOnPause(dismissDate.isChecked()); 
       dpd.showYearPickerFirst(showYearFirst.isChecked()); 
       dpd.setVersion(showVersion2.isChecked() ? DatePickerDialog.Version.VERSION_2 : DatePickerDialog.Version.VERSION_1); 
       if (modeCustomAccentDate.isChecked()) { 
        dpd.setAccentColor(Color.parseColor("#9C27B0")); 
       } 
       if (titleDate.isChecked()) { 
        dpd.setTitle("DatePicker Title"); 
       } 
       if (highlightDays.isChecked()) { 
        Calendar date1 = Calendar.getInstance(); 
        Calendar date2 = Calendar.getInstance(); 
        date2.add(Calendar.WEEK_OF_MONTH, -1); 
        Calendar date3 = Calendar.getInstance(); 
        date3.add(Calendar.WEEK_OF_MONTH, 1); 
        Calendar[] days = {date1, date2, date3}; 
        dpd.setHighlightedDays(days); 
       } 
       if (limitSelectableDays.isChecked()) { 
        Calendar[] days = new Calendar[13]; 
        for (int i = -6; i < 7; i++) { 
         Calendar day = Calendar.getInstance(); 
         day.add(Calendar.DAY_OF_MONTH, i * 2); 
         days[i + 6] = day; 
        } 
        dpd.setSelectableDays(days); 
       } 
       dpd.show(getFragmentManager(), "Datepickerdialog"); 
      } 
     }); 

     return view; 
    } 

    @Override 
    public void onResume() { 
     super.onResume(); 
     DatePickerDialog dpd = (DatePickerDialog) getFragmentManager().findFragmentByTag("Datepickerdialog"); 
     if(dpd != null) dpd.setOnDateSetListener(this); 
    } 

    @Override 
    public void onDateSet(DatePickerDialog view, int year, int monthOfYear, int dayOfMonth) { 
     String date = "You picked the following date: "+dayOfMonth+"/"+(++monthOfYear)+"/"+year; 
     dateTextView.setText(date); 
    } 
} 

Answer 4

button_name.setOnTouchListener(new View.OnTouchListener() { 
    @Override 
    public boolean onTouch(View v, MotionEvent event) { 

     switch (event.getAction()){ 
      case MotionEvent.ACTION_DOWN: 
       DatePickerDialog datePickerDialog = DatePickerDialog.newInstance(new DatePickerDialog.OnDateSetListener() { 
        @Override 
        public void onDateSet(DatePickerDialog view, int year, int monthOfYear, int dayOfMonth) { 
         String years=""+year; 
         String months=""+(monthOfYear+1); 
         String days=""+dayOfMonth; 
         if(monthOfYear>=0 && monthOfYear<9){ 
          months="0"+(monthOfYear+1); 
         } 
         if(dayOfMonth>0 && dayOfMonth<10){ 
          days="0"+dayOfMonth; 

         } 
         race_date.setText(months+"/"+days+"/"+years); 
        } 
       }, now.get(Calendar.YEAR), 
         now.get(Calendar.MONTH), 
         now.get(Calendar.DAY_OF_MONTH)); 
       datePickerDialog.setMinDate(now); 
       datePickerDialog.show(getActivity().getFragmentManager(), "Datepicker"); 
       break; 
     } 
     return false; 
    } 
});
