Android RadioGroup checks more than one RadioButton?

I am using RadioGroup, added RadioButton rdbut to RadioGroup rdgrp like rdgrp.addView(rdbut). 

   for(int j=0;j<3;j++)
   {
         RadioGroup rdgrp = new RadioGroup;
         for(int i=0;i<=10;i++)
         {
             RadioButton rdbut = new RadioButton(this);
             rdbut.setText("RadioButtion"+i);
             rdbut.setId(i);
             rdbut.setTag("somename");
             rdgrp.addView(rdbut);
         }
    }

the above code shows how I initialize the radiogroup and radio button. after I run the this code, in emulator/mobile , i am able to check 2 radio buttons at a time.

What could be the problem?

Use Some thing like this xml design in user layout file.

   <TableLayout
            android:id="@+id/tbl_layoutchoice"
            style="@style/InfoTableView"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="3dip" >

            <RadioGroup
                android:id="@+id/SelectLayout_Group"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content" >
            </RadioGroup>
 </TableLayout>

and For Use this RadioGroup in Activity 's OnCreate() Method and findView like this 

 mRadioGroup = (RadioGroup) this.findViewById(R.id.SelectLayout_Group);

and Then Use Below Code With Your Require Change To Add Radio Button in One RadioGroup.Use Also Below Require Declaration for Create Radio Button Dynamically.

     ArrayList<String> layoutlist = new ArrayList<String>(3);
     int index = -1;
     LayoutParams lp = new LayoutParams(LayoutParams.FILL_PARENT,
        LayoutParams.WRAP_CONTENT);


   for (String layout : layoutlist) {
        RadioButton r = new RadioButton(this);
        index++;
        r.setText(layout);
        r.setId(index);
        r.setLayoutParams(lp);
        r.setTextAppearance(this, R.style.TextBase);


        mRadioGroup.addView(r);


    }

So don't forget to add your String Value in layoutlist before for loop .and R.style is some Require Style for Text Show in RadioButton.

You have created three different Radio Group. You can select only one radio button from a single group.So from three groups you can select three buttons But there is no inter-group relationship. You can select radio buttons from different group simultaneously. In your case you can select three buttons at max.

Thanks Sunil

Change your code like this.

  RadioGroup rdgrp[] = new RadioGroup[3];

  For(int j=0;j<3;j++)
   {
         RadioButton rdbut[] = new RadioButton[10];
         For(int i=0;i<=10;i++)
         {

             rdbut[i].setText("RadioButtion"+i);
             rdbut[i].setId(j*100+i);
             rdbut[i].setTag("somename");
             rdgrp[j].addView(rdbut[i]);
         }
    }
