Android: How to change CheckBox size?

Starting with API Level 11 there is another approach exists:

<CheckBox    ...    android:scaleX="0.70"    android:scaleY="0.70"/>

Here is a better solution which does not clip and/or blur the drawable, but only works if the checkbox doesn't have text itself (but you can still have text, it's just more complicated, see at the end).

<CheckBox    android:id="@+id/item_switch"    android:layout_width="160dp"    <!-- This is the size you want -->    android:layout_height="160dp"    android:button="@null"    android:background="?android:attr/listChoiceIndicatorMultiple"/>

The result:

What the previous solution with scaleX and scaleY looked like:

You can have a text checkbox by adding a TextView beside it and adding a click listener on the parent layout, then triggering the checkbox programmatically.

You just need to set the related drawables and set them in the checkbox:

<CheckBox     android:layout_width="wrap_content"     android:layout_height="wrap_content"    android:text="new checkbox"     android:background="@drawable/my_checkbox_background"    android:button="@drawable/my_checkbox" />

The trick is on how to set the drawables. Here's a good tutorial about this.
