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:

这里有一个更模块化和更清晰的方法来在Glide中循环裁剪你的位图:
通过扩展BitmapTransformation创建一个自定义转换,然后重写transform方法,如下所示:
为了Glide 4.x.x
public class CircularTransformation extends BitmapTransformation {
@Override
protected Bitmap transform(BitmapPool pool, Bitmap toTransform, int outWidth, int outHeight) {
RoundedBitmapDrawable circularBitmapDrawable =
RoundedBitmapDrawableFactory.create(null, toTransform);
circularBitmapDrawable.setCircular(true);
Bitmap bitmap = pool.get(outWidth, outHeight, Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
circularBitmapDrawable.setBounds(0, 0, outWidth, outHeight);
circularBitmapDrawable.draw(canvas);
return bitmap;
}
@Override
public void updateDiskCacheKey(MessageDigest messageDigest) {}
}
为了Glide 3.x.x
public class CircularTransformation extends BitmapTransformation {
@Override
protected Bitmap transform(BitmapPool pool, Bitmap toTransform, int outWidth, int outHeight) {
RoundedBitmapDrawable circularBitmapDrawable =
RoundedBitmapDrawableFactory.create(null, toTransform);
circularBitmapDrawable.setCircular(true);
Bitmap bitmap = pool.get(outWidth, outHeight, Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
circularBitmapDrawable.setBounds(0, 0, outWidth, outHeight);
circularBitmapDrawable.draw(canvas);
return bitmap;
}
@Override
public String getId() {
// Return some id that uniquely identifies your transformation.
return "CircularTransformation";
}
}
然后在Glide builder中设置你需要它的地方:
Glide.with(yourActivity)
.load(yourUrl)
.asBitmap()
.transform(new CircularTransformation())
.into(yourView);
希望这对你有所帮助。

您也可以使用这个实现,不过值得注意的是,这个实现是基于匕首柄的
提供程序实现
@Module
@Named("circleCrop")
@InstallIn(SingletonComponent::class)
object AppModule {
@Singleton
@Provides
fun provideGlideInstance(
@ApplicationContext context: Context
) = Glide.with(context).setDefaultRequestOptions(
RequestOptions()
.placeholder(R.drawable.logo)
.error(R.drawable.logo)
.apply(RequestOptions().circleCropTransform())
.diskCacheStrategy(DiskCacheStrategy.DATA)
)
}
依赖注入
@Inject
@Named("circleCrop")
lateinit var glide: RequestManager
加载图片
glide.load(hotel.image).into(imgItemSearch)
在这种情况下,我需要添加阴影,和imageView抬高不工作
实现“com.github.bumptech.glide:滑翔:4.10.0”
XML
<FrameLayout
android:id="@+id/fl_image"
android:layout_width="60dp"
android:layout_height="60dp"
android:layout_margin="10dp"
android:background="@drawable/card_circle_background"
android:elevation="8dp">
<ImageView
android:id="@+id/iv_item_employee"
android:layout_width="60dp"
android:layout_height="60dp"
tools:background="@color/colorPrimary" />
</FrameLayout>
可拉的形状
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<solid android:color="@color/white"/>
</shape>
滑翔的配置
Glide.with(this)
.asBitmap()
.load(item.image)
.apply(RequestOptions.circleCropTransform())
.into(iv_item_employee)
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 {
private int borderWidth;
private int canvasSize;
private Bitmap image;
private Paint paint;
private Paint paintBorder;
public CircularImageView(final Context context) {
this(context, null);
}
public CircularImageView(Context context, AttributeSet attrs) {
this(context, attrs, R.attr.circularImageViewStyle);
}
public CircularImageView(Context context, AttributeSet attrs, int defStyle) {
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;
this.requestLayout();
this.invalidate();
}
public void setBorderColor(int borderColor) {
if (paintBorder != null)
paintBorder.setColor(borderColor);
this.invalidate();
}
public void addShadow() {
setLayerType(LAYER_TYPE_SOFTWARE, paintBorder);
paintBorder.setShadowLayer(4.0f, 0.0f, 2.0f, Color.BLACK);
}
@Override
public void onDraw(Canvas canvas) {
// load the bitmap
image = drawableToBitmap(getDrawable());
// init shader
if (image != null) {
canvasSize = canvas.getWidth();
if(canvas.getHeight()<canvasSize)
canvasSize = canvas.getHeight();
BitmapShader shader = new BitmapShader(Bitmap.createScaledBitmap(image, canvasSize, canvasSize, false), Shader.TileMode.CLAMP, Shader.TileMode.CLAMP);
paint.setShader(shader);
// circleCenter is the x or y of the view's center
// radius is the radius in pixels of the cirle to be drawn
// paint contains the shader that will texture the shape
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
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
int width = measureWidth(widthMeasureSpec);
int height = measureHeight(heightMeasureSpec);
setMeasuredDimension(width, height);
}
private int measureWidth(int measureSpec) {
int result = 0;
int specMode = MeasureSpec.getMode(measureSpec);
int specSize = MeasureSpec.getSize(measureSpec);
if (specMode == MeasureSpec.EXACTLY) {
// The parent has determined an exact size for the child.
result = specSize;
} else if (specMode == MeasureSpec.AT_MOST) {
// The child can be as large as it wants up to the specified size.
result = specSize;
} else {
// The parent has not imposed any constraint on the child.
result = canvasSize;
}
return result;
}
private int measureHeight(int measureSpecHeight) {
int result = 0;
int specMode = MeasureSpec.getMode(measureSpecHeight);
int specSize = MeasureSpec.getSize(measureSpecHeight);
if (specMode == MeasureSpec.EXACTLY) {
// We were told how big to be
result = specSize;
} else if (specMode == MeasureSpec.AT_MOST) {
// The child can be as large as it wants up to the specified size.
result = specSize;
} else {
// Measure the text (beware: ascent is a negative number)
result = canvasSize;
}
return (result + 2);
}
public Bitmap drawableToBitmap(Drawable drawable) {
if (drawable == null) {
return null;
} else if (drawable instanceof BitmapDrawable) {
return ((BitmapDrawable) drawable).getBitmap();
}
Bitmap bitmap = Bitmap.createBitmap(drawable.getIntrinsicWidth(),
drawable.getIntrinsicHeight(), Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
drawable.setBounds(0, 0, canvas.getWidth(), canvas.getHeight());
drawable.draw(canvas);
return bitmap;
}
}
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..
Glide.with(MainActivity.this)
.load(personPhoto)
.transition(withCrossFade(500))
.apply(RequestOptions.circleCropTransform())
.thumbnail(0.5f)
.into(imageView);
Roman Samoylenko的答案是正确的,只是函数变了。 正确答案是
Glide.with(context)
.load(yourImage)
.apply(RequestOptions.circleCropTransform())
.into(imageView);
