I want to change the color of button when it clicked…
How i can do it? I don’t want to do it by using drawable folder…

Answer 1

use a selector , create a file xml in your drawable/ folder and name it bg_button.xml :

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:drawable="@drawable/back_button_clicked" android:state_pressed="true"></item>
    <item android:drawable="@drawable/back_button_clicked" android:state_focused="true"></item>
    <item android:drawable="@drawable/back_button_normal"></item>

</selector>

and then in your xml layout , define your button like this :

<Button android:id="@+id/button"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/bg_button" />

NB : back_button_clicked and back_button_normal are drawables for the background of your button.
the drawable back_button_clicked will be the background of your button when it will be clicked , and back_button_normal will be the background of your button in normal case.
