datepicker in child activity of activitygroup raises BadTokenException error

Question

I need to display two datepickers in a child activity of an activitygroup in a tabbed activity. the code for the two textviews and to buttons to display the date is:

  incorp_date=(TextView)findViewById(R.id.edt_incorpdate);
    incorp_date_image=(Button)findViewById(R.id.incorp_date);


    incorp_date_cal=Calendar.getInstance();

    incorp_date_image.setOnClickListener(new View.OnClickListener() {

        public void onClick(View v) {
            showDialog(DATE_PICKER_INCORP);
        }
    });

    final Calendar c = Calendar.getInstance();
    incorp_year = c.get(Calendar.YEAR);
    incorp_month = c.get(Calendar.MONTH);
    incorp_day = c.get(Calendar.DAY_OF_MONTH);

    /* display the current date (this method is below)  */
    updateIncorpDisplay();


    estb_date=(TextView)findViewById(R.id.edt_estabdate);
    estb_date_image=(Button)findViewById(R.id.estb_date);
    estb_date_cal=Calendar.getInstance();

    estb_date_image.setOnClickListener(new View.OnClickListener() {

        public void onClick(View v) {
            showDialog(DATE_PICKER_ESTB);
        }
    });
    final Calendar c1 = Calendar.getInstance();
    estb_year = c1.get(Calendar.YEAR);
    estb_month = c1.get(Calendar.MONTH);
    estb_day = c1.get(Calendar.DAY_OF_MONTH);

    /* display the current date (this method is below)  */
    updateEstbDisplay();

the code to display the datepicker dialog is:

incorp_dateListener=new OnDateSetListener() {

        @Override
        public void onDateSet(DatePicker view, int year, int monthOfYear,
                int dayOfMonth) {
            // TODO Auto-generated method stub
            incorp_year = year;
            incorp_month = monthOfYear;
            incorp_day = dayOfMonth;
            updateIncorpDisplay();
        }
    };

    estb_dateListener=new OnDateSetListener() {

        @Override
        public void onDateSet(DatePicker view, int year, int monthOfYear,
                int dayOfMonth) {
            // TODO Auto-generated method stub
            estb_year = year;
            estb_month = monthOfYear;
            estb_day = dayOfMonth;
            updateEstbDisplay();
        }
    };
  @Override
protected Dialog onCreateDialog(int id) {

    switch(id){
        case DATE_PICKER_INCORP:
                return new DatePickerDialog(getParent(), incorp_dateListener, incorp_year, incorp_month, incorp_day); 
            case DATE_PICKER_ESTB:
                return new DatePickerDialog(getParent(), estb_dateListener, estb_year, estb_month, estb_day);
    }
        return null;
}

I am not able to display the datepicker dialog. the application force closes when i click the button and an exception of BadTokenException is raised.. what should i do??? I cant seem to figure out what the problem is??? I think maybe its because its a child activity of an activitygroup.. but cant find any relevant solution.. Please help!!!!

Answer 1

Try Something like this,First you create tabcontext object in your TabActivity Class.like this

package com.loanreminder;

import android.app.TabActivity;
import android.os.Bundle;

/**
 * @author Adil Soomro
 * 
 */
public class TabSample extends TabActivity {
    /** Called when the activity is first created. */
    public static TabSample tabContext;

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.tabhost);
        tabContext = this;

    }

}

After Use this Object Like this in Your activity.

protected Dialog onCreateDialog(int id) {

    switch(id){
        case DATE_PICKER_INCORP:
                return new DatePickerDialog(TabSample.tabContext, incorp_dateListener, incorp_year, incorp_month, incorp_day); 
            case DATE_PICKER_ESTB:
                return new DatePickerDialog(TabSample.tabContext, estb_dateListener, estb_year, estb_month, estb_day);
    }
        return null;
}

Answer 2

Do something like this

     switch (id) {
case DATE_DIALOG_ID:
 return new DatePickerDialog(getParent(),
             mDateSetListener,
             mYear, mMonth, mDay);
case DATE_DIALOG_ID_RETURN:
 return new DatePickerDialog(getParent(),
   mDateSetListenerreturn,
             mYear, mMonth, mDay);     
 }

I got this solution from Android: DatePicker not working inside Actvity
