final ImageSwitcher switcher = (ImageSwitcher)findViewById(R.id.switcher);this.image.setInAnimation(AnimationUtils.makeInAnimation(this, true)); // true从左淡入,false从右淡入this.image.setOutAnimation(AnimationUtils.makeOutAnimation(this, true)); // true从右淡出,false从左淡入出//this.image.setInAnimation(this, android.R.anim.fade_in);  //淡入//this.image.setOutAnimation(this, android.R.anim.fade_out); //淡出switcher.setFactory(new ViewFactory(){    @Override    public View makeView()    {        ImageView imageView = new ImageView(GridViewTest.this);        imageView.setBackgroundColor(0xff0000);        imageView.setScaleType(ImageView.ScaleType.FIT_CENTER);        //LayoutParams类很重要 ，包导错了，一直报类转换异常的错误        imageView.setLayoutParams(new ImageSwitcher.LayoutParams(                android.widget.Gallery.LayoutParams.WRAP_CONTENT, android.widget.Gallery.LayoutParams.WRAP_CONTENT));        return imageView;    }});
