} }用法
Glide.with(this).load(R.mipmap.pretty_1).bitmapTransform( new GlideRoundCornersTransUtils(this,25,GlideRoundCornersTransUtils.CornerType.TOP)).into(iv_Round2);如果要加载圆角如下
public class GlideCircleTransUtils extends BitmapTransformation { public GlideCircleTransUtils(Context context) { super(context); } @Override protected Bitmap transform(BitmapPool pool, Bitmap toTransform, int outWidth, int outHeight) { return circleCrop(pool, toTransform); } private static Bitmap circleCrop(BitmapPool pool, Bitmap source) { if (source == null) return null; //获取资源的长宽,获取最小值 子位图的像素个数 int size = Math.min(source.getWidth(), source.getHeight()); // 子位图第一个像素在源位图的X坐标 int x = (source.getWidth() - size) / 2; //子位图第一个像素在源位图的y坐标 int y = (source.getHeight() - size) / 2; //创建新位图 source 源位图 Bitmap squared = Bitmap.createBitmap(source, x, y, size, size); //返回一个正好匹配给定宽、高和配置的只包含透明像素的Bitmap // 如果BitmapPool中找不到这样的Bitmap，就返回null Bitmap result = pool.get(size, size, Bitmap.Config.ARGB_8888); //当返回null 时,创建给定宽、高和配置的新位图 if (result == null) { result = Bitmap.createBitmap(size, size, Bitmap.Config.ARGB_8888); } //画图 Canvas canvas = new Canvas(result); Paint paint = new Paint(); // 设置shader paint.setShader(new BitmapShader(squared, BitmapShader.TileMode.CLAMP, BitmapShader.TileMode.CLAMP)); //抗锯齿 paint.setAntiAlias(true); float r = size / 2f; // 用设置好的画笔绘制一个圆 canvas.drawCircle(r, r, r, paint); return result; } @Override public String getId() { return getClass().getName(); } }用法如下
Glide.with(this).load(imgurl).transform(new GlideCircleTransUtils(this)).into(iv_circle);以上就是关于视频直播系统源码，加载圆角图片用到的相关代码，更多内容欢迎关注之后的文章 本文转载自网络，转载仅为分享干货知识，如有侵权欢迎联系云豹科技进行删除处理
