1- Android ImageButton

In Android, ImageButton is a user interface control, which displays as a button with an image, and allows the user to click to perform an action.

ImageButton is a subclass of ImageView, so you can set an Icon for it by using the app:srcCompat attribute. Note that unlike Button, ImageButton is not possible to display text on it.

<ImageButton
    android:id="@+id/imageButton"
    app:srcCompat="@drawable/icon_feel_good"
    ... />

There are other types of buttons that you can take a look in the following articles:

Android Button

Android ToggleButton

Android RadioGroup and RadioButton

As for Java code, there are several methods that help you set the Icon for ImageButton. All of them are inherited from ImageView.

setImageBitmap(Bitmap bitmap)
setImageDrawable(Drawable drawable)
setImageIcon(Icon icon)
setImageResource(int resId)
setImageURI(Uri uri)

Android ImageView

The style attribute is an option of ImageButton. It permits you to set styles for the ImageButton. There are some styles available in Android library that may be ready to use.

    app:srcCompat="@drawable/icon_feel_good"
