Animation for radio button

Question

I have one radio group contains two radio button :

<RadioGroup
    android:id="@+id/radios"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_gravity="right"
    android:inputType="text"
    android:orientation="vertical" >

    <RadioButton
        android:id="@+id/first"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="right"
        android:button="@null"
        android:drawablePadding="30dp"
        android:drawableRight="@drawable/selector_radio"
        android:text="2 times"
        android:textSize="20sp"
        android:layout_marginLeft="20dp" />

    <RadioButton
        android:id="@+id/second"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:button="@null"
        android:drawablePadding="30dp"
        android:drawableRight="@drawable/selector_radio"
        android:text="3 times"
        android:textSize="20sp"
        android:layout_marginLeft="20dp" />
</RadioGroup>

And now I want to add animation to radio button. I have two animation for each state of radio button For example : animation_radio_off :

    <animation-list xmlns:android="http://schemas.android.com/apk/res/android" >
        <item
            android:drawable="@drawable/btn_off_00"
            android:duration="10"/>
       <item
            android:drawable="@drawable/btn_off_00"
            android:duration="10"/>
......
    </animation-list>

animation_radio_off is like animation_radio_on just change picture. My selector:

selector_radio.xml:

    <?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >

    <item
        android:drawable="@drawable/animation_radio_on"
        android:state_checked="true" />
    <item
        android:drawable="@drawable/animation_radio_off"
        android:state_checked="false"/>

</selector>

But something error happend and my app can not run. I spend many time to search about animation for radio button. I also refer this link : Android Radio Button Animation.

But i gusse it not fit my case. Do you have any idea for my problem ? Thanks you. Edit: my log cat:

Answer 1

I would ask for a logcat, but from the top of my head, you are setting the button itself to null in the layout, and then you (probably) instruct the resource manager to assign to it your animations, so maybe your problem is there.

I don't see where you assign the animation to the radio button (you probably do it in code).

Logcat and code would be helpful in shedding more light on this.
