Android开发之--将imageview设置圆角 并通过Glide加载出来

首先  一个类 继承 BitmapTransformation

public class GlideRoundTransform extends BitmapTransformation {    private static float radius = 0f;    public GlideRoundTransform(Context context) {        this(context, 4);    }    public GlideRoundTransform(Context context, int dp) {        super(context);        this.radius = Resources.getSystem().getDisplayMetrics().density * dp;    }    @Override    protected Bitmap transform(BitmapPool pool, Bitmap toTransform, int outWidth, int outHeight) {        return roundCrop(pool, toTransform);    }    private static Bitmap roundCrop(BitmapPool pool, Bitmap source) {        if (source == null) return null;        Bitmap result = pool.get(source.getWidth(), source.getHeight(), Bitmap.Config.ARGB_8888);        if (result == null) {            result = Bitmap.createBitmap(source.getWidth(), source.getHeight(), Bitmap.Config.ARGB_8888);        }        Canvas canvas = new Canvas(result);        Paint paint = new Paint();        paint.setShader(new BitmapShader(source, BitmapShader.TileMode.CLAMP, BitmapShader.TileMode.CLAMP));        paint.setAntiAlias(true);        RectF rectF = new RectF(0f, 0f, source.getWidth(), source.getHeight());        canvas.drawRoundRect(rectF, radius, radius, paint);        return result;    }    @Override    public String getId() {        return getClass().getName() + Math.round(radius);    }}

然后  在需要变成圆角的地方 使用

image = findViewById(R.id.image);

Glide.with(this).load("goodinfo.image").transform(new GlideRoundTransform(this,10)).into(image);

如：

Glide.with(this).load(campareBean.before_image).diskCacheStrategy(DiskCacheStrategy.ALL).placeholder(R.drawable.img_default_default).transform(new GlideRoundTransform(this)).into(ivBeforeImg);
