我创建了发光效果 imageview 应用程序。它工作正常，我的问题是发光效果左，右，下，顶部有点隐藏，所以我正在尝试设置填充，但我仍然有同样的问题。如何解决这个问题呢？
代码：
ImageView mImageBk = (ImageView)itemTemplate.findViewById(R.id.imgBk);
RelativeLayout.LayoutParams ImgBKLayoutParams = new RelativeLayout.LayoutParams(scrWidth/8 + scrWidth/20, scrWidth/8 + scrWidth/20 );
ImgBKLayoutParams.leftMargin =0;
ImgBKLayoutParams.topMargin = 0;
mImageBk.setLayoutParams(ImgBKLayoutParams);
mImageBk.setImageResource(R.drawable.glow_effect);
mImageBk.setPadding(10, 10, 10, 10);
mImageBk.setVisibility(View.GONE);
