I have many RadioButtons in my app. The RadioButtons are too big for me. Is there any way to make them smaller?

Can't be done, the radio button is a built-in control component and as such its size is fixed.
无法完成，单选按钮是内置控件组件，因此其大小是固定的。

One quick hacky solution is to scale the button down:
一种快速的hacky解决方案是将按钮缩小：
<RadioButton
android:scaleX="0.5"
android:scaleY="0.5" />
This works great for going smaller.
这非常适合变小。
For going larger, this tends to cause some clipping from the container View, so you'll likely have to hardcode the height/width of the RadioGroup to fit the scaled buttons. The button drawable can also get noticeably pixelated the larger you go, so it's not really great if you want something 3x larger...
为了变大，这往往会导致容器视图中的一些剪辑，因此您可能必须对 RadioGroup 的高度/宽度进行硬编码以适合缩放的按钮。按钮 drawable 也可以在你放大的时候明显像素化，所以如果你想要 3 倍大的东西并不是很好......

It canbe done but is not as simple as setting the Layout_Width and Layout_height as with EditTexts, Buttons etc. To modify the size/looks of a view like a checkbox/radio button use the "Background" and "Button" properties to specify your own drawables.
它可以完成，但并不像使用 EditTexts、Buttons 等设置 Layout_Width 和 Layout_height 那样简单。要修改视图的大小/外观，如复选框/单选按钮，请使用“背景”和“按钮”属性来指定您的自己的drawable。

you can use scalex and scaley properties , then use translationX and translationY to put it in the radiobutton windows.
您可以使用 scalex 和 scaley 属性，然后使用 translationX 和 translationY 将其放在单选按钮窗口中。
<RadioButton
android:id="@+id/rbtnfkilo"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:scaleX="1.4"
android:scaleY="1.4"
android:text="Kilogram"
android:textColor="#fff"
android:textSize="18sp"
android:translationX="24dp" />

I relpaced RadioButtonwith ToggleButtonand applied same style. I did override background and button.
我重新RadioButton使用ToggleButton并应用了相同的样式。我确实覆盖了背景和按钮。
<ToggleButton
android:id="@+id/btnToggle1"
android:layout_width="match_parent"
android:layout_height="30dp"
android:layout_weight="1"
android:checked="true"
style="@style/ToggleButtonStyle"
android:button="@null"
android:textOn="@string/btnTitle"
android:textOff="@string/btnTitle"/>
and style:
和风格：
<style name="ToggleButtonStyle">
<item name="android:background">@drawable/background_radiobutton</item>
<item name="android:textColor">@color/selector_text_radiobutton</item>
<item name="android:textAppearance">@null</item>
</style>
Works for me - looks the same, but with custom height.
对我有用 - 看起来一样，但具有自定义高度。
If your RadioButton is in the RadioGroup, you will need to customize listener, check Android: How to get a radiogroup with togglebuttons?
如果您的 RadioButton 在 RadioGroup 中，您将需要自定义侦听器，请查看 Android：How to get a radiogroup with togglebuttons？

I've done this by adjusting the TextSize of RadioButton itself
我通过调整 RadioButton 本身的 TextSize 来做到这一点
Like so
像这样
android:textSize="20sp"
then apply to my code;
然后适用于我的代码；
<RadioGroup
android:id="@+id/checkboxRadioButton"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:orientation="horizontal">
<RadioButton
android:id="@+id/rb1"
style="@android:style/Widget.CompoundButton.CheckBox"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="@dimen/checkBoxMargin"
android:text="YES"
android:textSize="20sp" />
...
Hope this help to someone
