Question

I\'m just wondering if there is any significant difference between an ImageView that\'s set to be clickable, compared with an ImageButton?

Answer 1

ImageButton is inherited from ImageView

public class ImageButton extends ImageView {
public ImageButton(Context context) {
    this(context, null);
}

public ImageButton(Context context, AttributeSet attrs) {
    this(context, attrs, com.android.internal.R.attr.imageButtonStyle);
}

public ImageButton(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
    setFocusable(true);
}

@Override
protected boolean onSetAlpha(int alpha) {
    return false;
}

@Override
public void onInitializeAccessibilityEvent(AccessibilityEvent event) {
    super.onInitializeAccessibilityEvent(event);
    event.setClassName(ImageButton.class.getName());
}

@Override
public void onInitializeAccessibilityNodeInfo(AccessibilityNodeInfo info) {
    super.onInitializeAccessibilityNodeInfo(info);
    info.setClassName(ImageButton.class.getName());
}
