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:

当前回答
最简单的方法(需要Glide 4.x.x)
Glide.with(context).load(uri).apply(RequestOptions.circleCropTransform()).into(imageView)
其他回答
现在在Glide V4中,你可以直接使用CircleCrop()
Glide.with(fragment)
.load(url)
.circleCrop()
.into(imageView);
内置类型
CenterCrop FitCenter CircleCrop
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" />
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..
你可以简单地调用roundedcornerstrtransform构造函数,它有一个拐角类型的枚举输入。是这样的:
Glide.with(context)
.load(bizList.get(position).getCover())
.bitmapTransform(new RoundedCornersTransformation(context,20,0, RoundedCornersTransformation.CornerType.TOP))
.into(holder.bizCellCoverImg);
但首先你必须添加滑翔转换到你的项目。
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);
