    	mImageView02 = (ImageView)findViewById(R.id.image02);
    	
    	//获取壁纸返回值是Drawable
    	Drawable drawable = getWallpaper();
    	//将Drawable转化为Bitmap
    	Bitmap bitmap = ImageUtil.drawableToBitmap(drawable);
    	//缩放图片
    	Bitmap zoomBitmap = ImageUtil.zoomBitmap(bitmap, 100, 100);
    	//获取圆角图片
    	Bitmap roundBitmap = ImageUtil.getRoundedCornerBitmap(zoomBitmap, 10.0f);
    	//获取倒影图片
    	Bitmap reflectBitmap = ImageUtil.createReflectionImageWithOrigin(zoomBitmap);
    	//这里可以让Bitmap再转化为Drawable
//    	Drawable roundDrawable = new BitmapDrawable(roundBitmap);    	
//    	Drawable reflectDrawable = new BitmapDrawable(reflectBitmap);   	
//    	mImageView01.setBackgroundDrawable(roundDrawable);
//    	mImageView02.setBackgroundDrawable(reflectDrawable);
    	    	
    	mImageView01.setImageBitmap(roundBitmap);
    	mImageView02.setImageBitmap(reflectBitmap);
