How can we reduce the size of checkbox? Please give me an idea.
You can reduce the size of the checkbox by changing its layout_width & layout_height.
Everything is standard, put in layout xml:
<CheckBox android:id="@+id/myCheckBoxId"
android:checked="false"
android:text="Check It!"
android:textSize="12"/> <!--look here --/>
Use android:scaleX="0.5" android:scaleY="0.5"
1 is for 100% size 0.5 is for 50% 0.4 is for 40%...
UPDATE: this only works from API 17 onwards...
CheckBox
derives its height from the TEXT as well as the image.
Set these properties in your XML:
android:text=""
android:textSize="0sp"
Of course this only works if you want no text (worked for me).
Without these changes, the CheckBox
was giving me a big margin around my image, as mentioned by Joe Plante.
You can just use scaleX and scaleY properies:
<CheckBox
android:id="@+id/check_box"
android:scaleX="2.5"
android:scaleY="2.5"/>
You can define your owm state list drawable, to define different images for different states, as below:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!--When checkbox is checked-->
<item android:state_checked="true" android:drawable="@drawable/img_checkbox_on" />
<!--When checkbox is not checked-->
<item android:state_checked="false" android:drawable="@drawable/img_checkbox_off" />
</selector>
and apply this selector to check box in xml by:
<CheckBox android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:button="@drawable/my_custom_checkbox" />
