Android Development Tutorial
In android we can customize the customize the default checkboxes. Default checkboxes are small and also not attractive, By using customized checkboxes we can design more attractive and better user interface.
To customize checkboxes we need to define our own drawables for checked and unchecked state.
In this example I have used these two drawables for checked and unchecked state.
We need to define the xml for our customized checkboxes
create the custom_checkbox_design.xml file and put it in drawable folder( if drawable folder is not there ,cerate it (inside res folder, and put custom_checkbox_design.xm file in this folder). It should look like following in pacakgae explorer
res
-> drawable
-> custom_checkbox_design.xml
custom_checkbox_design.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="true" android:drawable="@drawable/checked" />
<item android:state_checked="false" android:drawable="@drawable/unchecked" />
</selector>
In checkbox set android:button property to the custom_checkbox_design.xml drawable like
android:button="@drawable/custom_checkbox_design"
See the differences in default checkbox and customize checkbox in below screenshot.
main.xml
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
xmlns:android="http://schemas.android.com/apk/res/android">
<TextView
android:id="@+id/textView1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="30dp"
android:gravity="center_horizontal"
android:textSize="25dp"
android:text="Default Check box" />
<!-- Default Checkboxes -->
<CheckBox
android:id="@+id/checkBoxDeafult1"

android:text="Checked Checkbox"
