机器人：创建圆形图像与毕加索

问题描述

这个问题已经被问及曾出现过的，我现在用的是很版毕加索做了一个承诺：如何发送一个圆形的位图使用毕加索的ImageView的？我是很新的毕加索和唯一的事情我已经使用迄今

The question had been asked and there had been a promise made for the very version of Picasso that I am using: How do I send a circular bitmap to an ImageView using Picasso? I am very new to Picasso and only thing I have used so far is

Picasso.with(context).load(url).resize(w, h).into(imageview);

我已经找到 https://gist.github.com/julianshen/5829333 ，但我不知道怎么样将其与线结合上面以非ackward方式

I have already found https://gist.github.com/julianshen/5829333 but I am not sure how to combine it with the line above in a non-ackward way.

推荐答案

研究了一下之前因为有答案avaiable.Anyhow，按照此链接并仔细阅读，了解如何使用它 -

Research a bit before as there are answers avaiable.Anyhow, follow This Link and read it carefully to know how to use it-

试试这个---

import com.squareup.picasso.Transformation;

public class CircleTransform implements Transformation {
    @Override
    public Bitmap transform(Bitmap source) {
        int size = Math.min(source.getWidth(), source.getHeight());

        int x = (source.getWidth() - size) / 2;
        int y = (source.getHeight() - size) / 2;

        Bitmap squaredBitmap = Bitmap.createBitmap(source, x, y, size, size);
        if (squaredBitmap != source) {
            source.recycle();
        }

        Bitmap bitmap = Bitmap.createBitmap(size, size, source.getConfig());

        Canvas canvas = new Canvas(bitmap);
        Paint paint = new Paint();
        BitmapShader shader = new BitmapShader(squaredBitmap,
                BitmapShader.TileMode.CLAMP, BitmapShader.TileMode.CLAMP);
        paint.setShader(shader);
        paint.setAntiAlias(true);

        float r = size / 2f;
        canvas.drawCircle(r, r, r, paint);

        squaredBitmap.recycle();
        return bitmap;
    }

    @Override
    public String key() {
        return "circle";
    }
}

然后简单地套用什么样子---

then simply apply it like---

Picasso.with(activity).load(mayorShipImageLink).transform(new CircleTransform()).into(ImageView);
