Android: ImageSwitcher getImageId()

Have a question. I'm using image sw开发者_StackOverflowitcher, and this is the way how I set Image to switcher...

 imageSwitcher.setImageResource(some_image_id);

So the question is: How to get image id that is set to image switcher ? I cannot find method like imageSwitcher.getImageId(); Thanks...

ImageSwitcher is a derived class from ViewAnimator, so you can use:

android.widget.ViewAnimator#getDisplayedChild () 

to get the index of the currently displayed child view, or:

android.widget.ViewAnimator#getCurrentView ()

to get the View corresponding to the currently displayed child.

If you look at the source code, setImageResource(int) adds an ImageView:

public void setImageResource(int resid)
{
    ImageView image = (ImageView)this.getNextView();
    image.setImageResource(resid);
    showNext();
}
