Question

我有一个广播组包含两个单选按钮：

<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>

现在我想将动画添加到单选按钮。我为每个单选按钮状态设置了两个动画例如： 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就像animation_radio_on只是改变图片。我的选择器：

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>

但是发生了一些错误，我的应用无法运行。我花了很多时间来搜索关于单选按钮的动画。我也请参考此链接：Android Radio Button Animation。

但我认为这不适合我的情况。你对我的问题有任何想法吗？谢谢。编辑：我的日志猫：

Answer 1

我会要求一个logcat，但是从我的头脑中，你在布局中将按钮本身设置为null，然后你（可能）指示资源管理器为其分配你的动画，所以也许你的问题在那里。

我没有看到您将动画分配到单选按钮的位置（您可能在代码中执行此操作）。

Logcat和代码将有助于更多地了解这一点。

单选按钮的动画
