推荐答案

对于动画，您可以使用以下代码：

For animation you can use this code:

public static void ImageViewAnimatedChange(Context c, final ImageView v, final Bitmap new_image) {
        final Animation anim_out = AnimationUtils.loadAnimation(c, android.R.anim.fade_out);
        final Animation anim_in  = AnimationUtils.loadAnimation(c, android.R.anim.fade_in);
        anim_out.setAnimationListener(new Animation.AnimationListener()
        {
            @Override public void onAnimationStart(Animation animation) {}
            @Override public void onAnimationRepeat(Animation animation) {}
            @Override public void onAnimationEnd(Animation animation)
            {
                v.setImageBitmap(new_image);
                anim_in.setAnimationListener(new Animation.AnimationListener() {
                    @Override public void onAnimationStart(Animation animation) {}
                    @Override public void onAnimationRepeat(Animation animation) {}
                    @Override public void onAnimationEnd(Animation animation) {}
                });
                v.startAnimation(anim_in);
            }
        });
        v.startAnimation(anim_out);
    }
