Text leftside of a RadioButton with a margin on Android
提问by Yalla T.
I want to have the "label", - the text you set in your RadioButtonto show left of the button and have some padding in between.
我想要“标签”， - 您在RadioButton按钮中设置的文本显示在按钮的左侧，并且中间有一些填充。
Adding an additional TextViewinto the layout doesn't work because my RadioGroupdoes not work (i can choose multiple buttons) if i add anything other then a RadioButtoninto the RadioGroup.
TextView在布局中添加其他内容不起作用，因为RadioGroup如果我RadioButton在RadioGroup.
So, how can i change the RadioButton to be <text><buttondrawable>instead of <buttondrawable><text>
那么，如何将 RadioButton 更改<text><buttondrawable>为<buttondrawable><text>

You can achieve this by setting android:button="@null"and adding the drawable of the RadioButtonas android:drawableRight. You can change the Padding between the text and the drawable with android:drawablePadding.
您可以通过设置android:button="@null"和添加RadioButtonas的 drawable来实现这一点android:drawableRight。您可以使用 更改文本和可绘制对象之间的填充android:drawablePadding。
<RadioGroup
android:id="@+id/radios"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:inputType="text"
android:orientation="vertical" >
<RadioButton
android:id="@+id/first"
android:button="@null"
android:drawableRight="@android:drawable/btn_radio"
android:drawablePadding="20dp"
android:layout_width="200dip"
android:layout_height="wrap_content"
android:text="@string/first"
android:textSize="20dip" />
<RadioButton
android:id="@+id/second"
android:button="@null"
android:drawableRight="@android:drawable/btn_radio"
android:drawablePadding="20dp"
android:layout_width="200dip"
android:layout_height="wrap_content"
android:text="@string/second"
android:textSize="20dip" />
</RadioGroup>
</RelativeLayout>

The answer above makes the image have no selected state.
上面的答案使图像没有选择状态。
May this help you:
可以帮助你：
On API <= 16 you can set padding left on the radio button to set the padding relative to the radio button's view bounds. Additionally a patch nine background also changes the view bounds relative to the view.
On API 17 the left padding is in relation to the radio button drawable. Same applies to the about a patch nine. To better illustrate padding differences see the attached screen shot.
在 API <= 16 上，您可以在单选按钮上设置 padding left 以设置相对于单选按钮视图边界的 padding。此外，补丁九背景也会改变相对于视图的视图边界。
在 API 17 上，左内边距与可绘制的单选按钮有关。同样适用于大约补丁九。为了更好地说明填充差异，请参阅附加的屏幕截图。
If you dig through the code you will find a new method in api 17 called getHorizontalOffsetForDrawables. This method is called when calculating the left padding for a radio button(hence the additional space illustrated in the picture).
如果您仔细阅读代码，您会在 api 17 中找到一个名为 getHorizontalOffsetForDrawables 的新方法。在计算单选按钮的左填充时调用此方法（因此图片中显示了额外的空间）。
TL;DR You should have radio button style for the min sdk you are supporting and another style for api 17+
TL;DR 你应该为你支持的 min sdk 设置单选按钮样式，并为 api 17+ 设置另一种样式

you can also change layout direction right to left and align text to start
您还可以从右到左更改布局方向并对齐文本以开始
android:layoutDirection="rtl"
android:textAlignment="textStart"
