How to use XML to specify two images for Android togglebutton
If you want to use XML to specify two images for an Android togglebutton, you can do so by defining a state list drawable. A state list drawable is a drawable resource that displays different graphics depending on the state of the object it's attached to.
To create a state list drawable for a togglebutton, you will need to create an XML file in your project's /res/drawable/ directory. Here's an example of what that XML file might look like:
<?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/toggle_on" /> <item android_state_checked="false" android_drawable="@drawable/toggle_off" /> </selector>
In this example, we're defining a selector that has two items. The first item is the "on" state of the togglebutton, which is specified by the android_state_checked="true" attribute. The drawable for this state is set to @drawable/toggle_on. The second item is the "off" state of the togglebutton, specified by the android_state_checked="false" attribute. The drawable for this state is set to @drawable/toggle_off.
You can then set this state list drawable as the background for your togglebutton in your layout XML file like this:
<ToggleButton android_id="@+id/my_togglebutton" android_layout_width="wrap_content" android_layout_height="wrap_content" android_background="@drawable/my_togglebutton_selector" />
In this example, we're setting the background of a togglebutton to the state list drawable we defined earlier, which is named my_togglebutton_selector.
By using a state list drawable, you can easily specify two images for an Android togglebutton using XML.
