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:

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)

简单的解决方案 通过使用这个库 实现“de.hdodenhof: circleimageview: 3.1.0”
<de.hdodenhof.circleimageview.CircleImageView
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/profile_image"
android:layout_width="96dp"
android:layout_height="96dp"
android:src="@drawable/profile"
app:civ_border_width="2dp"
app:civ_border_color="#FF000000"/>
Glide.load(url)
.centerCrop()
.placeholder(R.drawable.loading_spinner)
.animate(R.anim.fade_in)
.into(YourImageView);
你必须使用CircularImageView来显示那种类型的图像…
您正在使用Glide库,用于加载图像..
创建一个类文件在你的项目和加载它在Imageview…你会得到你想要的结果…
试试下面的代码…
XML
<com.yourpackage.CircularImageView
android:id="@+id/imageview"
android:layout_width="96dp"
android:layout_height="96dp"
app:border="true"
app:border_width="3dp"
app:border_color="@color/white"
android:src="@drawable/image" />
CircularImageView.java
public class CircularImageView extends ImageView {

this(context, null);

public CircularImageView(Context context, AttributeSet attrs) {

super(context, attrs, defStyle);
// init paint
paint = new Paint();
paint.setAntiAlias(true);
paintBorder = new Paint();
paintBorder.setAntiAlias(true);
// load the styled attributes and set their properties
TypedArray attributes = context.obtainStyledAttributes(attrs, R.styleable.CircularImageView, defStyle, 0);
if(attributes.getBoolean(R.styleable.CircularImageView_border, true)) {
int defaultBorderSize = (int) (4 * getContext().getResources().getDisplayMetrics().density + 0.5f);
setBorderWidth(attributes.getDimensionPixelOffset(R.styleable.CircularImageView_border_width, defaultBorderSize));
setBorderColor(attributes.getColor(R.styleable.CircularImageView_border_color, Color.WHITE));
}
if(attributes.getBoolean(R.styleable.CircularImageView_shadow, false))
addShadow();

public void setBorderWidth(int borderWidth) {
this.borderWidth = borderWidth;

int circleCenter = (canvasSize - (borderWidth * 2)) / 2;
canvas.drawCircle(circleCenter + borderWidth, circleCenter + borderWidth, ((canvasSize - (borderWidth * 2)) / 2) + borderWidth - 4.0f, paintBorder);
canvas.drawCircle(circleCenter + borderWidth, circleCenter + borderWidth, ((canvasSize - (borderWidth * 2)) / 2) - 4.0f, paint);
}

@Override

public Bitmap drawableToBitmap(Drawable drawable) {

注意:
你可以使用
CircularImageView imgIcon = (CircularImageView)findViewById(R.id.imageview);
or
ImageView imgIcon = (ImageView)findViewById(R.id.imageview);
它不会影响你的其他库…不必改变你的代码下载图像或其他任何东西… 它可以简单地定义使用XML太..
不要附加太多的函数,如placeholder(), transition()等,只要让它像这段代码一样简单,它就可以工作了。
Glide.with(mContext)
.load(datas.getUser_img())
.centerCrop()
.into(ivAvator);
为了Glide 4.x.x
use
Glide
.with(context)
.load(uri)
.apply(
RequestOptions()
.circleCrop())
.into(imageView)
医生说
圆形图片:CircleImageView/CircularImageView/RoundedImageView 已知与TransitionDrawable (.crossFade()有问题 .thumbnail()或.placeholder())和动画gif,使用 BitmapTransformation (.circleCrop()将在v4中可用)或 .dontAnimate()来修复这个问题
我之前在找它,我用最简单的方法做了它,我希望你会喜欢。
//crete this method into your Utils class and call this method wherever you want to use.
//you can set these placeHolder() and error() image static as well. I made it as comment inside this method, then no need to use [placeHolderUrl and errorImageUrl] parameters. remove it from this method.
public static void loadImage(final Activity context, ImageView imageView, String url, int placeHolderUrl, int errorImageUrl) {
if (context == null || context.isDestroyed()) return;
//placeHolderUrl=R.drawable.ic_user;
//errorImageUrl=R.drawable.ic_error;
Glide.with(context) //passing context
.load(getFullUrl(url)) //passing your url to load image.
.placeholder(placeHolderUrl) //this would be your default image (like default profile or logo etc). it would be loaded at initial time and it will replace with your loaded image once glide successfully load image using url.
.error(errorImageUrl)//in case of any glide exception or not able to download then this image will be appear . if you won't mention this error() then nothing to worry placeHolder image would be remain as it is.
.diskCacheStrategy(DiskCacheStrategy.ALL) //using to load into cache then second time it will load fast.
.transform(new CircleTransform(context))//this CircleTransform class help to crop an image as circle.
.animate(R.anim.fade_in) // when image (url) will be loaded by glide then this face in animation help to replace url image in the place of placeHolder (default) image.
.fitCenter()//this method help to fit image into center of your ImageView
.into(imageView); //pass imageView reference to appear the image.
}
CircleTransform.java
public class CircleTransform extends BitmapTransformation {
public CircleTransform(Context context) {
super(context);
if(context==null)
return;
}
private static Bitmap circleCrop(BitmapPool pool, Bitmap source) {
if (source == null) return null;
int size = Math.min(source.getWidth(), source.getHeight());
int x = (source.getWidth() - size) / 2;
int y = (source.getHeight() - size) / 2;
Bitmap squared = Bitmap.createBitmap(source, x, y, size, size);
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);
return result;
}
@Override
protected Bitmap transform(BitmapPool pool, Bitmap toTransform, int outWidth, int outHeight) {
return circleCrop(pool, toTransform);
}
@Override
public String getId() {
return getClass().getName();
}
}
Fade_in.xml用于渐隐动画。
<set xmlns:android="http://schemas.android.com/apk/res/android">
<!--THIS ANIMATION IS USING FOR FADE IN -->
<alpha
android:duration="800"
android:fromAlpha="0.0"
android:interpolator="@android:anim/decelerate_interpolator"
android:toAlpha="1.0" />
最后调用此方法。
Utils.loadImage(YourClassName.this,mImageView,url,R.drawable.ic_user,R.drawable.ic_error);
