Custom UI in Android

Question

Android

I've been digging a development theme for Androyd for about a week. The following question arose - if I suppose I had to radically change the appearance, for example, of a button - (Button) - how can this be done? It means that I want to use my images and so on.

Answer 1

For a Button, you can define your own look by setting images for its different states (pressed / in focus / not pressed):

<Button android:id="@+id/my_button"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="My Text"
    android:background="@drawable/mybutton_background"/>

Where in drawable/mybutton_background are instructions on which images to use, for example:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_focused="true" 
    	  android:state_pressed="false" 
    	  android:drawable="@android:drawable/grey_button_background_focus_blue" />
    <item android:state_focused="true" 
    	  android:state_pressed="true"
    	  android:drawable="@android:drawable/grey_button_background_pressed_blue" />
    <item android:state_focused="false" 
    	  android:state_pressed="true"
    android:drawable="@android:drawable/grey_button_background_pressed_blue" />
    <item android:drawable="@android:drawable/grey_button_background_normal" />
</selector>
