是否可以更改android单选按钮组中的单选按钮图标

Is it possible to change the radio button icon in an android radio button group

提问by yamspog

I am wanting to allow the user of my android application the ability to set some parameters. The radio button is ideal for this situation. However, I don't like the radio buttons are rendered.

我想让我的 android 应用程序的用户能够设置一些参数。单选按钮非常适合这种情况。但是，我不喜欢呈现单选按钮。

Is it possible to change the radio button icon? For example, is it possible to create a custom layout for each row and in that layout reference my own icon and change the font et al.

是否可以更改单选按钮图标？例如，是否可以为每一行创建自定义布局，并在该布局中引用我自己的图标并更改字体等。

Yes that's possible you have to define your own style for radio buttons, at res/values/styles.xml:

是的，您可能必须在 res/values/styles.xml 中为单选按钮定义自己的样式：

<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="CustomTheme" parent="android:Theme">
   <item name="android:radioButtonStyle">@style/RadioButton</item>
</style>
<style name="RadioButton" parent="@android:style/Widget.CompoundButton.RadioButton">
   <item name="android:button">@drawable/radio</item>
</style>
</resources>

'radio' here should be a stateful drawable, radio.xml:

这里的“radio”应该是一个有状态的 drawable，radio.xml：

    <?xml version="1.0" encoding="utf-8"?>
    <selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_checked="true" android:state_window_focused="false"
        android:drawable="@drawable/radio_hover" />
    <item android:state_checked="false" android:state_window_focused="false"
        android:drawable="@drawable/radio_normal" />
    <item android:state_checked="true" android:state_pressed="true"
        android:drawable="@drawable/radio_active" />
    <item android:state_checked="false" android:state_pressed="true"
        android:drawable="@drawable/radio_active" />
    <item android:state_checked="true" android:state_focused="true"
        android:drawable="@drawable/radio_hover" />
    <item android:state_checked="false" android:state_focused="true"
        android:drawable="@drawable/radio_normal_off" />
    <item android:state_checked="false" android:drawable="@drawable/radio_normal" />
    <item android:state_checked="true" android:drawable="@drawable/radio_hover" />
    </selector>

Then just apply the Custom theme either to whole app or to activities of your choice.

然后只需将自定义主题应用于整个应用程序或您选择的活动。

You can put custom image in radiobutton like normal button. for that create one XML file in drawable folder e.g

您可以像普通按钮一样将自定义图像放在单选按钮中。为此在可绘制文件夹中创建一个 XML 文件，例如

<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/sub_screens_aus_hl" 
    android:state_pressed="true"/>  
<item android:drawable="@drawable/sub_screens_aus" 
    android:state_checked="true"/>  
<item android:drawable="@drawable/sub_screens_aus" 
    android:state_focused="true" />
<item android:drawable="@drawable/sub_screens_aus_dis" />  
</selector> 

Here you can use 3 different images for radiobutton

在这里，您可以为单选按钮使用 3 个不同的图像

and use this file to RadioButton like:

并将此文件用于 RadioButton，例如：

android:button="@drawable/aus"
android:layout_height="120dp"
android:layout_width="wrap_content"

The easier way to only change the radio button is simply set selector for drawable right

仅更改单选按钮的更简单方法是将选择器设置为可绘制右侧

<RadioButton
    ...
    android:button="@null"
    android:checked="false"
    android:drawableRight="@drawable/radio_button_selector" />

And the selector is:

选择器是：

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/ic_checkbox_checked" android:state_checked="true" />
    <item android:drawable="@drawable/ic_checkbox_unchecked" android:state_checked="false" /></selector>

That's all

就这样

In case you want to do it programmatically,

如果您想以编程方式执行此操作，

checkBoxOrRadioButton.setButtonDrawable(null);
checkBoxOrRadioButton.setBackgroundResource(R.drawable.resource_name);

Here's probably a quick approach,

这可能是一个快速的方法，

With two icons shown above, you shall have a RadioGroupsomething like this

上面显示了两个图标，你应该有一个RadioGroup这样的东西

• change the RadioGroup's orientation to horizontal
• for each RadioButton's Properties, try giving the icon for Buttonunder CompoundButton,
• adjust the Padding and size,
• and set the Background attribute when checked.

• 将RadioGroup的方向更改为水平
• 对于每个RadioButton的属性，请尝试为Buttonunder提供图标CompoundButton，
• 调整填充和大小，
• 并在选中时设置背景属性。
