Question

You know sometimes when a button or picture is pressed, and the image gets smaller, then when you release it, it goes back to normal. How would i do that in android studio with an image-button

Answer 1

您可以在按钮上有onclicklistener或onlongPresslistener ，当它按下时，您可以减小用于显示图像的imageview的大小，当释放按钮时，您可以显示原始图像。

Answer 2

create one xml file in drawable like this and set as a background

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

    <item android:drawable="@drawable/YourHoverImage" android:state_pressed="true"/>
    <item android:drawable="@drawable/NormalImage" android:state_pressed="false"/>
    <item android:drawable="@drawable/YourHoverImage" android:state_focused="true"/>
    <!-- default -->

</selector>

you can do like this.
