How to change location of Android xml source file with radio button?

Question

I have 3 xml source files like this:

XmlPullParser xmlR =  params[0].getXml(R.xml.code_1);
XmlPullParser xmlR =  params[0].getXml(R.xml.code_2);
XmlPullParser xmlR =  params[0].getXml(R.xml.code_3);

And this is my radio button:

<RelativeLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_below="@id/separator2"
        android:layout_marginLeft="10dp"
        android:layout_marginRight="10dp"
        android:layout_marginTop="10dp"
        android:orientation="horizontal" >

        <RadioButton android:id="@+id/code_1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="code_1"
            android:onClick="onRadioButtonClicked"
            />

        <RadioButton
            android:id="@+id/code_2"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerInParent="true"
            android:text="code_2"
            android:onClick="onRadioButtonClicked"
             />

        <RadioButton
            android:id="@+id/code_3"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentRight="true"
            android:onClick="onRadioButtonClicked"
            android:text="code_3" />

    </RelativeLayout>

How to select just one of the xml files with radio button? So, when I select one of radio button, the xml code_1 or xml code_2 or xml code_3 will be used.

Thanks.

Use RadioGroup as a parent view for all your radio buttons so only 1 of them can be selected at a time — EtherPaul, Jun 16 '17 at 18:29

First of all, you need to group your radio buttons in a RadioGroup[1] layout, then you'll have to set an OnCheckedChangeListener[2] this way you'll be able to know which radio button is selected at a time.

RadioGroup.OnCheckedChangeListener(RadioGroup group, int checkedId)

The checkedId relates to the selected RadioButton, so you can use your xml based on it.

You need to inflate your xml programatically!!! Just do this and it will work!
