    Calendar c = Calendar.getInstance(); 
    int year= c.get(Calendar.YEAR); 
    int month = c.get(Calendar.MONTH);

     setContentView(R.layout.addcar_layout); 
     registration_ET = (EditText) this.findViewById(R.id.firstRegistration_editText); 
     registration_ET.setOnClickListener(new OnClickListener() { 

      @Override 
      public void onClick(View v) { 
       // TODO Auto-generated method stub

      } 
     }); 
     control_ET = (EditText) this.findViewById(R.id.control_editText); 
     control_ET.setOnClickListener(new OnClickListener() {

Modifiez simplement votre DatePickerFragment comme suit.

public class DatePickerFragment extends DialogFragment { 

    @Override 
    public Dialog onCreateDialog(Bundle savedInstanceState) { 
     super.onCreateDialog(savedInstanceState); 
     Calendar c = Calendar.getInstance(); 
     int year = c.get(Calendar.YEAR); 
     int month = c.get(Calendar.MONTH); 
     int day_of_month = c.get(Calendar.DAY_OF_MONTH); 
     DatePickerDialog dialog = new DatePickerDialog(getActivity(), STYLE_NORMAL, (DatePickerDialog.OnDateSetListener) getActivity(), year, month, day_of_month); 
     dialog.getDatePicker().setTag(getTag()); 
     return dialog; 
    } 
} 

Note:

J'ai ajouté deux lignes suivantes à votre code.

DatePickerDialog dialog = new DatePickerDialog(getActivity(), STYLE_NORMAL, (DatePickerDialog.OnDateSetListener) getActivity(), year, month, day_of_month); 
dialog.getDatePicker().setTag(getTag()); 

Maintenant vous pouvez obtenir votre balise de onDateSet méthode comme suit.

@Override 
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) { 
    if (view.getTag().equals("DateRegisterId")) { 
     registration_ET.setText(monthOfYear + "/" + dayOfMonth + "/" + year); 
    } else if (view.getTag().equals("controlId")) { 
     control_ET.setText(monthOfYear + "/" + dayOfMonth + "/" + year); 
    } 
}

1. DatePickerFragment.java

package com.example.androidtester; 

import android.app.DatePickerDialog; 
import android.app.Dialog; 
import android.os.Bundle; 
import android.support.v4.app.DialogFragment; 

import java.util.Calendar; 

public class DatePickerFragment extends DialogFragment { 

    @Override 
    public Dialog onCreateDialog(Bundle savedInstanceState) { 
     super.onCreateDialog(savedInstanceState); 
     Calendar c = Calendar.getInstance(); 
     int year = c.get(Calendar.YEAR); 
     int month = c.get(Calendar.MONTH); 
     int day_of_month = c.get(Calendar.DAY_OF_MONTH); 
     DatePickerDialog dialog = new DatePickerDialog(getActivity(), STYLE_NORMAL, (DatePickerDialog.OnDateSetListener) getActivity(), year, month, day_of_month); 
     dialog.getDatePicker().setTag(getTag()); 
     return dialog; 
    } 
} 

2. MainActivity.java

package brightspot.com.androidtester; 

import android.app.DatePickerDialog; 
import android.os.Bundle; 
import android.support.v7.app.AppCompatActivity; 
import android.view.View; 
import android.widget.DatePicker; 
import android.widget.EditText; 


public class MainActivity extends AppCompatActivity implements DatePickerDialog.OnDateSetListener { 

    private EditText editText; 
    private EditText editText2; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     editText = (EditText) findViewById(R.id.editText); 
     editText2 = (EditText) findViewById(R.id.editText2); 
     final DatePickerFragment newFrag = new DatePickerFragment(); 
     editText.setOnClickListener(new View.OnClickListener() { 

      @Override 
      public void onClick(View v) { 
       // TODO Auto-generated method stub 
       newFrag.show(getSupportFragmentManager(), "editText"); 
      } 
     }); 

     editText2.setOnClickListener(new View.OnClickListener() { 

      @Override 
      public void onClick(View v) { 
       newFrag.show(getSupportFragmentManager(), "editText2"); 
      } 
     }); 
    } 

    @Override 
    public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) { 
     if (view.getTag().equals("editText")) { 
      editText.setText(monthOfYear + "/" + dayOfMonth + "/" + year); 
     } else if (view.getTag().equals("editText2")) { 
      editText2.setText(monthOfYear + "/" + dayOfMonth + "/" + year); 
     } 
    } 
} 

I J'espère que ceci vous aidera.
