有人知道如何用Glide显示圆角图像吗? 我正在用Glide加载图像,但我不知道如何将圆角参数传递给这个库。

我需要显示图像像下面的例子:

滑翔V4:

    Glide.with(context)
        .load(url)
        .circleCrop()
        .into(imageView);

滑翔V3:

您可以使用RoundedBitmapDrawable圆形图像与Glide。不需要自定义ImageView。

 Glide.with(context).load(url).asBitmap().centerCrop().into(new BitmapImageViewTarget(imageView) {
        @Override
        protected void setResource(Bitmap resource) {
            RoundedBitmapDrawable circularBitmapDrawable =
                    RoundedBitmapDrawableFactory.create(context.getResources(), resource);
            circularBitmapDrawable.setCircular(true);
            imageView.setImageDrawable(circularBitmapDrawable);
        }
    });

Glide 4.6.1版本

Glide.with(context)
.load(url)
.apply(RequestOptions.bitmapTransform(new CircleCrop()))
.into(imageView);

使用这个转换,它会工作得很好。

public class CircleTransform extends BitmapTransformation {
public CircleTransform(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;

    int borderColor = ColorUtils.setAlphaComponent(Color.WHITE, 0xFF);
    int borderRadius = 3;

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

    // TODO this could be acquired from the pool too
    Bitmap squared = Bitmap.createBitmap(source, x, y, size, size);
    if (squared != source) {
        source.recycle();
    }

    Bitmap result = pool.get(size, size, Bitmap.Config.ARGB_8888);
    if (result == null) {
        result = Bitmap.createBitmap(size, size, Bitmap.Config.ARGB_8888);
    }

    Canvas canvas = new Canvas(result);
    Paint paint = new Paint();
    paint.setShader(new BitmapShader(squared, BitmapShader.TileMode.CLAMP, BitmapShader.TileMode.CLAMP));
    paint.setAntiAlias(true);
    float r = size / 2f;
    canvas.drawCircle(r, r, r, paint);

    // Prepare the background
    Paint paintBg = new Paint();
    paintBg.setColor(borderColor);
    paintBg.setAntiAlias(true);

    // Draw the background circle
    canvas.drawCircle(r, r, r, paintBg);

    // Draw the image smaller than the background so a little border will be seen
    canvas.drawCircle(r, r, r - borderRadius, paint);

    squared.recycle();

    return result;
}

@Override
public String getId() {
    return getClass().getName();
}} 

圆圈裁剪+占位符+交叉渐隐

 Glide.with(context!!)
                    .load(randomImage)
                    .apply(RequestOptions.bitmapTransform(CircleCrop()).error(R.drawable.nyancat_animated))
                    .transition(DrawableTransitionOptions()
                            .crossFade())
                    .into(picture)

它很简单,我看过Glide图书馆,它非常好的图书馆和论文基础上的volley谷歌的图书馆

使用此库查看圆形图像

https://github.com/hdodenhof/CircleImageView

now

//一个简单的视图

 @Override
 public void onCreate(Bundle savedInstanceState) {
  ...

  CircleImageView civProfilePic = (CircleImageView)findViewById(R.id.ivProfile);
  Glide.load("http://goo.gl/h8qOq7").into(civProfilePic);
}

//对于一个列表:

@Override
public View getView(int position, View recycled, ViewGroup container) {
final ImageView myImageView;
 if (recycled == null) {
    myImageView = (CircleImageView) inflater.inflate(R.layout.my_image_view,
            container, false);
} else {
    myImageView = (CircleImageView) recycled;
}

String url = myUrls.get(position);

Glide.load(url)
    .centerCrop()
    .placeholder(R.drawable.loading_spinner)
    .animate(R.anim.fade_in)
    .into(myImageView);

  return myImageView;
}

以及XML格式

<de.hdodenhof.circleimageview.CircleImageView
   android:id="@+id/ivProfile
   android:layout_width="160dp"
   android:layout_height="160dp"
   android:layout_centerInParent="true"
   android:src="@drawable/hugh"
   app:border_width="2dp"
   app:border_color="@color/dark" />

最简单的方法(需要Glide 4.x.x)

Glide.with(context).load(uri).apply(RequestOptions.circleCropTransform()).into(imageView)
