Scale picasso bitmap to fill height in CircleImageView

I'm using a https://github.com/hdodenhof/CircleImageView library, but also tried several others and it didn't help. I need to load image from server with picasso, like this mPicasso.load(url).into(mCircularImageView). However I always get this:
But I need to achieve this:
Tried to call resize(100,100), fit(), transform(new CircleTransorm()),
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";
}
}
nothing of the above helped.
My layout:
<de.hdodenhof.circleimageview.CircleImageView
android:id="#+id/account_profile_picture"
style="#style/ProfilePicture"
android:layout_gravity="center_horizontal"/>
Style:
<style name="ProfilePicture">
<item name="android:layout_width">#dimen/profile_picture_size</item>
<item name="android:layout_height">#dimen/profile_picture_size</item>
<item name="android:src">#drawable/profile_picture_placeholder</item>
<item name="civ_border_width">1dp</item>
<item name="civ_border_color">#FF000000</item>
</style>

White fit() defers the call until the view is loaded and measured, it does not achieve the results that you want. You need to add centerCrop() in order to achieve the expected output:
mPicasso.load(url).fit().centerCrop().into(mCircularImageView)

Just set this attribute to your circleimageview
android:scaleType="centerCrop"
This should do it.
Thank You

please use this you can create dynamic imageview, i hope this will help you.

canvas.drawBitmap(sbmp, rect, rect, paint);
return output;
}
}

You dont need to add any library for circular image view.
Android api already provides
RoundedBitmapDrawable
to use for this purpose. I have used Glide library to do what you want -
Glide.with(context)
.load(imageUrl)
.asBitmap()
.placeholder(R.color.gray)
.diskCacheStrategy(DiskCacheStrategy.ALL)
.centerCrop()
.into(new BitmapImageViewTarget(imageView){
#Override
public void onResourceReady(Bitmap resource, GlideAnimation<? super Bitmap> glideAnimation) {
RoundedBitmapDrawable circularBitmapDrawable =
RoundedBitmapDrawableFactory.create(context.getResources(), resource);
circularBitmapDrawable.setCircular(true);
imageView.setImageDrawable(circularBitmapDrawable);
}
#Override
public void onLoadFailed(Exception e, Drawable errorDrawable) {
imageView.setImageResource(R.drawable.profile);
}
});

What I am seeing in your code is you are using both circle transformation and circle image view. for make circle you have to use only one approach, I am suggestion go with circle transformation also change your circle image view to simple image view.
mPicasso.load(url).resize(300,300).centerCrop().transform (new CircleTransform ()).into(mImageView);
hope It will help.

How to have a circular, center-cropped imageView, without creating a new bitmap?

Note: I know there are a lot of questions and repositories about this, but none seems to fit what I try to achieve.
Background
Given a bitmap of any aspect-ratio, I wish to set it as the content of an ImageView (using a drawable only, without extending the ImageView), so that the content will be center-cropped, and yet in the shape of a circle.
All of this, with minimal memory usage, because the images could be quite large sometimes. I do not want to create a whole new Bitmap just for this. The content is already there...
The problem
All solutions I've found lack one of the things I've written: some do not center-crop, some assume the image is square-shaped, some create a new bitmap from the given bitmap...
What I've tried
Other than trying various repositories, I've tried this tutorial, and I tried to fix it for the case of non-square aspect ratios, but I've failed.
Here's its code, in case the website will get closed:
public class RoundImage extends Drawable {
private final Bitmap mBitmap;
private final Paint mPaint;
private final RectF mRectF;
private final int mBitmapWidth;
private final int mBitmapHeight;
public RoundImage(Bitmap bitmap) {
mBitmap = bitmap;
mRectF = new RectF();
mPaint = new Paint();
mPaint.setAntiAlias(true);
mPaint.setDither(true);
final BitmapShader shader = new BitmapShader(bitmap, Shader.TileMode.CLAMP, Shader.TileMode.CLAMP);
mPaint.setShader(shader);
mBitmapWidth = mBitmap.getWidth();
mBitmapHeight = mBitmap.getHeight();
}
#Override
public void draw(Canvas canvas) {
canvas.drawOval(mRectF, mPaint);
}
#Override
protected void onBoundsChange(Rect bounds) {
super.onBoundsChange(bounds);
mRectF.set(bounds);
}
#Override
public void setAlpha(int alpha) {
if (mPaint.getAlpha() != alpha) {
mPaint.setAlpha(alpha);
invalidateSelf();
}
}
#Override
public void setColorFilter(ColorFilter cf) {
mPaint.setColorFilter(cf);
}
#Override
public int getOpacity() {
return PixelFormat.TRANSLUCENT;
}
#Override
public int getIntrinsicWidth() {
return mBitmapWidth;
}
#Override
public int getIntrinsicHeight() {
return mBitmapHeight;
}
public void setAntiAlias(boolean aa) {
mPaint.setAntiAlias(aa);
invalidateSelf();
}
#Override
public void setFilterBitmap(boolean filter) {
mPaint.setFilterBitmap(filter);
invalidateSelf();
}
#Override
public void setDither(boolean dither) {
mPaint.setDither(dither);
invalidateSelf();
}
public Bitmap getBitmap() {
return mBitmap;
}
}
A very good solution I've found (here) does exactly what I need, except it uses it all in the ImageView itself, instead of creating a drawable. This means that I can't set it, for example, as the background of a view.
The question
How can I achieve this?
EDIT: this is the current code, and as I wanted to add border, it also has this code for it:
public class SimpleRoundedDrawable extends BitmapDrawable {
private final Path p = new Path();
private final Paint mBorderPaint = new Paint(Paint.ANTI_ALIAS_FLAG);
public SimpleRoundedDrawable(final Resources res, final Bitmap bitmap) {
super(res, bitmap);
mBorderPaint.setStyle(Paint.Style.STROKE);
}
public SimpleRoundedDrawable setBorder(float borderWidth, #ColorInt int borderColor) {
mBorderPaint.setStrokeWidth(borderWidth);
mBorderPaint.setColor(borderColor);
invalidateSelf();
return this;
}
#Override
protected void onBoundsChange(Rect bounds) {
super.onBoundsChange(bounds);
p.rewind();
p.addCircle(bounds.width() / 2,
bounds.height() / 2,
Math.min(bounds.width(), bounds.height()) / 2,
Path.Direction.CW);
}
#Override
public void draw(Canvas canvas) {
canvas.clipPath(p);
super.draw(canvas);
final float width = getBounds().width(), height = getBounds().height();
canvas.drawCircle(width / 2, height / 2, Math.min(width, height) / 2, mBorderPaint);
}
}
I hope this is how things should really work.
EDIT: It seems that the solution works only from specific Android version, as it doesn't work on Android 4.2.2. Instead, it shows a squared image.
EDIT: it seems that the above solution is also much less efficient than using BitmapShader (Link here). It would be really great to know how to use it within a drawable instead of within a customized ImageView
--
Here's the current modified version of the below solutions. I hope it will be handy for some people:
public class SimpleRoundedDrawable extends Drawable {
final Paint mMaskPaint = new Paint(Paint.ANTI_ALIAS_FLAG), mBorderPaint = new Paint(Paint.ANTI_ALIAS_FLAG);
Bitmap mBitmap;
int mSide;
float mRadius;
public SimpleRoundedDrawable() {
this(null);
}
public SimpleRoundedDrawable(Bitmap bitmap) {
this(bitmap, 0, 0);
}
public SimpleRoundedDrawable(Bitmap bitmap, float width, #ColorInt int color) {
mBorderPaint.setStyle(Paint.Style.STROKE);
mBitmap = bitmap;
mSide = mBitmap == null ? 0 : Math.min(bitmap.getWidth(), bitmap.getHeight());
mBorderPaint.setStrokeWidth(width);
mBorderPaint.setColor(color);
}
public SimpleRoundedDrawable setBitmap(final Bitmap bitmap) {
mBitmap = bitmap;
mSide = Math.min(bitmap.getWidth(), bitmap.getHeight());
invalidateSelf();
return this;
}
public SimpleRoundedDrawable setBorder(float width, #ColorInt int color) {
mBorderPaint.setStrokeWidth(width);
mBorderPaint.setColor(color);
invalidateSelf();
return this;
}
#Override
protected void onBoundsChange(Rect bounds) {
if (mBitmap == null)
return;
Matrix matrix = new Matrix();
RectF src = new RectF(0, 0, mSide, mSide);
src.offset((mBitmap.getWidth() - mSide) / 2f, (mBitmap.getHeight() - mSide) / 2f);
RectF dst = new RectF(bounds);
final float strokeWidth = mBorderPaint.getStrokeWidth();
if (strokeWidth > 0)
dst.inset(strokeWidth, strokeWidth);
matrix.setRectToRect(src, dst, Matrix.ScaleToFit.CENTER);
Shader shader = new BitmapShader(mBitmap, Shader.TileMode.CLAMP, Shader.TileMode.CLAMP);
shader.setLocalMatrix(matrix);
mMaskPaint.setShader(shader);
matrix.mapRect(src);
mRadius = src.width() / 2f;
}
#Override
public void draw(Canvas canvas) {
Rect b = getBounds();
if (mBitmap != null)
canvas.drawCircle(b.exactCenterX(), b.exactCenterY(), mRadius, mMaskPaint);
final float strokeWidth = mBorderPaint.getStrokeWidth();
if (strokeWidth > 0)
canvas.drawCircle(b.exactCenterX(), b.exactCenterY(), mRadius + strokeWidth / 2, mBorderPaint);
}
#Override
public void setAlpha(int alpha) {
mMaskPaint.setAlpha(alpha);
invalidateSelf();
}
#Override
public void setColorFilter(ColorFilter cf) {
mMaskPaint.setColorFilter(cf);
invalidateSelf();
}
#Override
public int getOpacity() {
return PixelFormat.TRANSLUCENT;
}
}

If I'm following you correctly, your Drawable class would be like so:
public class CroppedDrawable extends BitmapDrawable {
private Path p = new Path();
public CroppedDrawable(Bitmap b) {
super(b);
}
#Override
protected void onBoundsChange(Rect bounds) {
super.onBoundsChange(bounds);
p.rewind();
p.addCircle(bounds.width() / 2,
bounds.height() / 2,
Math.min(bounds.width(), bounds.height()) / 2,
Path.Direction.CW);
}
#Override
public void draw(Canvas canvas) {
canvas.clipPath(p);
super.draw(canvas);
}
}
An example usage would be:
Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.mila);
CroppedDrawable cd = new CroppedDrawable(bitmap);
imageView.setImageDrawable(cd);
Which, with your previous sample image, would give something like this:

try this minimalist custom Drawable and modify it to meet your needs:
class D extends Drawable {
Bitmap bitmap;
Paint maskPaint = new Paint(Paint.ANTI_ALIAS_FLAG);
Paint borderPaint = new Paint(Paint.ANTI_ALIAS_FLAG);
int side;
float radius;
public D(Bitmap wrappedBitmap) {
bitmap = wrappedBitmap;
borderPaint.setStyle(Paint.Style.STROKE);
borderPaint.setStrokeWidth(16);
borderPaint.setColor(0xcc220088);
side = Math.min(bitmap.getWidth(), bitmap.getHeight());
}
#Override
protected void onBoundsChange(Rect bounds) {
Matrix matrix = new Matrix();
RectF src = new RectF(0, 0, side, side);
src.offset((bitmap.getWidth() - side) / 2f, (bitmap.getHeight() - side) / 2f);
RectF dst = new RectF(bounds);
dst.inset(borderPaint.getStrokeWidth(), borderPaint.getStrokeWidth());
matrix.setRectToRect(src, dst, Matrix.ScaleToFit.CENTER);
Shader shader = new BitmapShader(bitmap, Shader.TileMode.CLAMP, Shader.TileMode.CLAMP);
shader.setLocalMatrix(matrix);
maskPaint.setShader(shader);
matrix.mapRect(src);
radius = src.width() / 2f;
}
#Override
public void draw(Canvas canvas) {
Rect b = getBounds();
canvas.drawCircle(b.exactCenterX(), b.exactCenterY(), radius, maskPaint);
canvas.drawCircle(b.exactCenterX(), b.exactCenterY(), radius + borderPaint.getStrokeWidth() / 2, borderPaint);
}
#Override public void setAlpha(int alpha) {}
#Override public void setColorFilter(ColorFilter cf) {}
#Override public int getOpacity() {return PixelFormat.TRANSLUCENT;}
}

As it seems, using "clipPath" isn't efficient and needs to have hardware-acceleration disabled on 4.3 and below.
A better solution is to use something like on this library, using BitmapShader :
https://github.com/hdodenhof/CircleImageView
which is based on :
http://www.curious-creature.com/2012/12/11/android-recipe-1-image-with-rounded-corners/
The relevant code is:
BitmapShader shader;
shader = new BitmapShader(bitmap, Shader.TileMode.CLAMP, Shader.TileMode.CLAMP);
Paint paint = new Paint();
paint.setAntiAlias(true);
paint.setShader(shader);
RectF rect = new RectF(0.0f, 0.0f, width, height);
// rect contains the bounds of the shape
// radius is the radius in pixels of the rounded corners
// paint contains the shader that will texture the shape
canvas.drawRoundRect(rect, radius, radius, paint);
I still wish to know how to do it all in a drawable, if the input is a bitmap.

A quick draft of a CircleImageDrawable based on my CircleImageView library. This does not create a new Bitmap, uses a BitmapShader to achieve the desired effect and center-crops the image.
public class CircleImageDrawable extends Drawable {
private final RectF mBounds = new RectF();
private final RectF mDrawableRect = new RectF();
private final RectF mBorderRect = new RectF();
private final Matrix mShaderMatrix = new Matrix();
private final Paint mBitmapPaint = new Paint();
private final Paint mBorderPaint = new Paint();
private int mBorderColor = Color.BLACK;
private int mBorderWidth = 0;
private Bitmap mBitmap;
private BitmapShader mBitmapShader;
private int mBitmapWidth;
private int mBitmapHeight;
private float mDrawableRadius;
private float mBorderRadius;
public CircleImageDrawable(Bitmap bitmap) {
mBitmap = bitmap;
mBitmapHeight = mBitmap.getHeight();
mBitmapWidth = mBitmap.getWidth();
}
#Override
public void draw(Canvas canvas) {
canvas.drawCircle(mBounds.width() / 2.0f, mBounds.height() / 2.0f, mDrawableRadius, mBitmapPaint);
if (mBorderWidth != 0) {
canvas.drawCircle(mBounds.width() / 2.0f, mBounds.height() / 2.0f, mBorderRadius, mBorderPaint);
}
}
#Override
protected void onBoundsChange(Rect bounds) {
super.onBoundsChange(bounds);
mBounds.set(bounds);
setup();
}
private void setup() {
mBitmapShader = new BitmapShader(mBitmap, Shader.TileMode.CLAMP, Shader.TileMode.CLAMP);
mBitmapPaint.setAntiAlias(true);
mBitmapPaint.setShader(mBitmapShader);
mBorderPaint.setStyle(Paint.Style.STROKE);
mBorderPaint.setAntiAlias(true);
mBorderPaint.setColor(mBorderColor);
mBorderPaint.setStrokeWidth(mBorderWidth);
mBorderRect.set(mBounds);
mBorderRadius = Math.min((mBorderRect.height() - mBorderWidth) / 2.0f, (mBorderRect.width() - mBorderWidth) / 2.0f);
mDrawableRect.set(mBorderRect);
mDrawableRect.inset(mBorderWidth, mBorderWidth);
mDrawableRadius = Math.min(mDrawableRect.height() / 2.0f, mDrawableRect.width() / 2.0f);
updateShaderMatrix();
invalidateSelf();
}
private void updateShaderMatrix() {
float scale;
float dx = 0;
float dy = 0;
mShaderMatrix.set(null);
if (mBitmapWidth * mDrawableRect.height() > mDrawableRect.width() * mBitmapHeight) {
scale = mDrawableRect.height() / (float) mBitmapHeight;
dx = (mDrawableRect.width() - mBitmapWidth * scale) * 0.5f;
} else {
scale = mDrawableRect.width() / (float) mBitmapWidth;
dy = (mDrawableRect.height() - mBitmapHeight * scale) * 0.5f;
}
mShaderMatrix.setScale(scale, scale);
mShaderMatrix.postTranslate((int) (dx + 0.5f) + mDrawableRect.left, (int) (dy + 0.5f) + mDrawableRect.top);
mBitmapShader.setLocalMatrix(mShaderMatrix);
}
#Override
public void setAlpha(int alpha) {
mBitmapPaint.setAlpha(alpha);
invalidateSelf();
}
#Override
public void setColorFilter(ColorFilter colorFilter) {
mBitmapPaint.setColorFilter(colorFilter);
invalidateSelf();
}
#Override
public int getOpacity() {
return 0;
}
}

There is already a built-in way to accomplish this and it's 1 line of code (ThumbnailUtils.extractThumbnail())
int dimension = getSquareCropDimensionForBitmap(bitmap);
bitmap = ThumbnailUtils.extractThumbnail(bitmap, dimension, dimension);
...
//I added this method because people keep asking how
//to calculate the dimensions of the bitmap...see comments below
public int getSquareCropDimensionForBitmap(Bitmap bitmap)
{
//If the bitmap is wider than it is tall
//use the height as the square crop dimension
if (bitmap.getWidth() >= bitmap.getHeight())
{
dimension = bitmap.getHeight();
}
//If the bitmap is taller than it is wide
//use the width as the square crop dimension
else
{
dimension = bitmap.getWidth();
}
}
If you want the bitmap object to be recycled, you can pass options that make it so:
bitmap = ThumbnailUtils.extractThumbnail(bitmap, dimension, dimension, ThumbnailUtils.OPTIONS_RECYCLE_INPUT);
Below is the link for the documentation:
ThumbnailUtils Documentation

CenterCrop is not working in universal image loader : Android

i am currently using Universal Image Loader 1.9.3 and initialize it as,
DisplayImageOptions defaultOptions = new DisplayImageOptions.Builder().displayer(new RoundedBitmapDisplayer(100)).cacheOnDisc().build();
ImageLoaderConfiguration.Builder builder = new ImageLoaderConfiguration.Builder(Register.this).defaultDisplayImageOptions(defaultOptions).memoryCache(new WeakMemoryCache());
ImageLoaderConfiguration config = builder.build();
imageLoader2 = ImageLoader.getInstance();
imageLoader2.init(config);
Here i have used RoundedBitmapDisplayer because i want image as round shape and i have set the property of image view in xml file as android:scaleType="centerCrop", so it must have result as center crop image but it didn't give center crop image.. images are stretched even gave center crop....

Yeah, it is mentioned that it always keep the aspect ratio, where changing scaletype property on xml wont work... use a coded crop instead
public static Bitmap toCropcenterfitoriginal(Bitmap srcBmp) {
Bitmap dstBmp = ThumbnailUtils.extractThumbnail(srcBmp,
srcBmp.getWidth() / 2, srcBmp.getWidth() / 3);
;
return dstBmp;
}

you can change the RoundedDrawable in the RoundedBitmapDisplayer with:
public static class RoundedDrawable extends Drawable {
protected final float cornerRadius;
protected final int margin;
protected RectF mRect = new RectF(),
mBitmapRect;
protected final BitmapShader bitmapShader;
protected final Paint paint;
protected Bitmap mBitmap;
public RoundedDrawable(Bitmap bitmap, int cornerRadius, int margin) {
this.cornerRadius = cornerRadius;
this.margin = margin;
mBitmap = bitmap;
bitmapShader = new BitmapShader(bitmap, Shader.TileMode.CLAMP, Shader.TileMode.CLAMP);
mBitmapRect = new RectF(margin, margin, bitmap.getWidth() - margin, bitmap.getHeight() - margin);
paint = new Paint();
paint.setAntiAlias(true);
paint.setShader(bitmapShader);
}
#Override
protected void onBoundsChange(Rect bounds) {
super.onBoundsChange(bounds);
mRect.set(margin, margin, bounds.width() - margin, bounds.height() - margin);
// Resize the original bitmap to fit the new bound
Matrix shaderMatrix = new Matrix();
// shaderMatrix.setRectToRect(mBitmapRect, mRect, Matrix.ScaleToFit.FILL);
int width = bounds.right - bounds.left;
int height = bounds.bottom - bounds.top;
float scale = width * 1.0f / mBitmap.getWidth();
// 如果根据宽度缩放后，高度小于targetHeight
if (scale * mBitmap.getHeight() < height) {
scale = height * 1.0f / mBitmap.getHeight();
}
int outWidth = Math.round(scale * mBitmap.getWidth());
int outHeight = Math.round(scale * mBitmap.getHeight());
shaderMatrix.postScale(scale, scale);
int left = 0;
int top = 0;
if (outWidth == width) {
top = (outHeight - height) * -1 / 2;
}
else {
left = (outWidth - width) * -1 / 2;
}
shaderMatrix.postTranslate(left, top);
bitmapShader.setLocalMatrix(shaderMatrix);
}
#Override
public void draw(Canvas canvas) {
canvas.drawRoundRect(mRect, cornerRadius, cornerRadius, paint);
}
#Override
public int getOpacity() {
return PixelFormat.TRANSLUCENT;
}
#Override
public void setAlpha(int alpha) {
paint.setAlpha(alpha);
}
#Override
public void setColorFilter(ColorFilter cf) {
paint.setColorFilter(cf);
}
}
then you can find your pic show in CenterCrop and rounded corner.
you can also check my github for detail: https://github.com/417704684/RoundCornerDrawable

This seems to be an open issue in Universal Image Loader. The work around that i can suggest for this is, load the image bitmap and then centercrop and corner round the bitmap as needed. Here is the code sample.
BaseActivity.imageLoader.loadImage(mUrl, mOptions, new ImageLoadingListener()
{
#Override
public void onLoadingStarted(String imageUri, View view) {
}
#Override
public void onLoadingFailed(String imageUri, View view, FailReason failReason)
{
}
#Override
public void onLoadingComplete(String imageUri, View view, Bitmap loadedImage)
{
if (loadedImage != null)
{
Bitmap croppedBitmap = ThumbnailUtils.extractThumbnail(loadedImage, HIQUtil.dpToPixel(getActivity(), 295), HIQUtil.dpToPixel(getActivity(), 211));
Bitmap roundedCropped = getRoundedCornerBitmap(croppedBitmap, 5);
imageView.setImageBitmap(roundedCropped);
}
}
#Override
public void onLoadingCancelled(String imageUri, View view) {
}
});
To get rounded corner bitmap, you can us this method:
public static Bitmap getRoundedCornerBitmap(Bitmap bitmap, int pixels) {
Bitmap output = Bitmap.createBitmap(bitmap.getWidth(), bitmap
.getHeight(), Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(output);
final int color = 0xff424242;
final Paint paint = new Paint();
final Rect rect = new Rect(0, 0, bitmap.getWidth(), bitmap.getHeight());
final RectF rectF = new RectF(rect);
final float roundPx = pixels;
paint.setAntiAlias(true);
canvas.drawARGB(0, 0, 0, 0);
paint.setColor(color);
canvas.drawRoundRect(rectF, roundPx, roundPx, paint);
paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));
canvas.drawBitmap(bitmap, rect, rect, paint);
return output;
}
Make sure to set
adjustViewBounds ="true"
in your imageview

Make Image view rounded (not the image)

Requirement is to:
Req 1 : Fetch images from url
R2: save them in cache
R3: make ImageView rounded not the image
So for R1 & R2 I found a library:
http://loopj.com/android-smart-image-view/
For R3 I've done a lot of R&D , & everything I found converts the image not the ImageView. This is what I've searched:
Mask ImageView with round corner background
How to make an ImageView with rounded corners?
https://github.com/vinc3m1/RoundedImageView
https://github.com/lopspower/CircularImageView
I know it's possible to use the ImageView bitmap & get the image rounded but with the specific library I want to use that isn't possible(maybe possible with very complex threading).
So please help me to get the ImageView rounded not the image.

so this is the minimalistic version:
class RoundImageView extends ImageView {
private static final int RADIUS = 32;
private Paint mPaint;
private Paint mSrcIn;
private RectF mRect;
public RoundImageView(Context context) {
super(context);
// setBackgroundColor(0xffffffff);
mSrcIn = new Paint();
mSrcIn.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
mPaint = new Paint(Paint.ANTI_ALIAS_FLAG);
mRect = new RectF();
}
#Override
public void onDraw(Canvas canvas) {
Drawable dr = getDrawable();
if (dr != null) {
mRect.set(dr.getBounds());
getImageMatrix().mapRect(mRect);
mRect.offset(getPaddingLeft(), getPaddingTop());
int rtc = canvas.saveLayer(mRect, null, Canvas.ALL_SAVE_FLAG);
// draw DST
canvas.drawRoundRect(mRect, RADIUS, RADIUS, mPaint);
canvas.saveLayer(mRect, mSrcIn, Canvas.ALL_SAVE_FLAG);
// draw SRC
super.onDraw(canvas);
canvas.restoreToCount(rtc);
}
}
}
or use even shorter one when hardware acceleration is not used and you can use Canvas.clipPath:
class RoundImageViewClipped extends ImageView {
private static final int RADIUS = 32;
private RectF mRect;
private Path mClip;
public RoundImageViewClipped(Context context) {
super(context);
// setBackgroundColor(0xffffffff);
mRect = new RectF();
mClip = new Path();
}
#Override
public void onDraw(Canvas canvas) {
Drawable dr = getDrawable();
if (dr != null) {
mRect.set(dr.getBounds());
getImageMatrix().mapRect(mRect);
mRect.offset(getPaddingLeft(), getPaddingTop());
mClip.reset();
mClip.addRoundRect(mRect, RADIUS, RADIUS, Direction.CCW);
canvas.clipPath(mClip);
super.onDraw(canvas);
}
}
}

I'm pretty sure you can't "make the ImageView round," since all Views are actually rectangular, so what you're going to have to do is fake it.
Use a method like this to cut a circle from the image:
public Bitmap getRoundedBitmap(Bitmap scaleBitmapImage) {
int targetRadius = scaleBitmapImage.getWidth();
if(targetRadius > scaleBitmapImage.getHeight()) targetRadius = scaleBitmapImage.getHeight();
Bitmap targetBitmap = Bitmap.createBitmap(targetRadius, targetRadius, Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(targetBitmap);
Path path = new Path();
path.addCircle(((float) scaleBitmapImage.getWidth() - 1) / 2, ((float) scaleBitmapImage.getHeight() - 1) / 2, (Math.min(((float) scaleBitmapImage.getWidth()), ((float) scaleBitmapImage.getHeight())) / 2), Path.Direction.CCW);
canvas.clipPath(path);
Bitmap sourceBitmap = scaleBitmapImage;
canvas.drawBitmap(sourceBitmap, new Rect(0, 0, sourceBitmap.getWidth(), sourceBitmap.getHeight()), new Rect(0, 0, scaleBitmapImage.getWidth(), scaleBitmapImage.getHeight()), null);
return targetBitmap;
}
Since the clipped part is transparent, it will appear as if the actual View is a circle. Also make sure that the bounds of the View are squared (or that adjustViewBounds="true") else you may get visual distortions in terms of width or height.
Pretty sure that's as close to a "rounded View" as you can actually get.

How about the solution give by Romain Guy to use a custom Drawable. You're ImageView will not be round and your source image will be untouched.
class StreamDrawable extends Drawable {
private final float mCornerRadius;
private final RectF mRect = new RectF();
private final BitmapShader mBitmapShader;
private final Paint mPaint;
private final int mMargin;
StreamDrawable(Bitmap bitmap, float cornerRadius, int margin) {
mCornerRadius = cornerRadius;
mBitmapShader = new BitmapShader(bitmap,
Shader.TileMode.CLAMP, Shader.TileMode.CLAMP);
mPaint = new Paint();
mPaint.setAntiAlias(true);
mPaint.setShader(mBitmapShader);
mMargin = margin;
}
#Override
protected void onBoundsChange(Rect bounds) {
super.onBoundsChange(bounds);
mRect.set(mMargin, mMargin, bounds.width() - mMargin, bounds.height() - mMargin);
}
#Override
public void draw(Canvas canvas) {
canvas.drawRoundRect(mRect, mCornerRadius, mCornerRadius, mPaint);
}
#Override
public int getOpacity() {
return PixelFormat.TRANSLUCENT;
}
#Override
public void setAlpha(int alpha) {
mPaint.setAlpha(alpha);
}
#Override
public void setColorFilter(ColorFilter cf) {
mPaint.setColorFilter(cf);
}
}

You can add rounded corners in a android view with the GradientDrawable.
So ,
GradientDrawable gd = new GradientDrawable();
gd.setColor(Color.TRANSPARENT);
gd.setCornerRadius(15f);
gd.setStroke(1f,Color.BLACK);
yourImageView.setBackground(gd);

SmartImageView extends from ImageView .. so you just have to extend from SmartImageView
Here is a working solution (based on pskink code & smartImageView lib )
Create a new Class
public class RoundedCornersSmartImageView extends SmartImageView{
private int RADIUS = 0;
private RectF mRect;
private Path mClip;
public RoundedCornersSmartImageView(Context context) {
super(context);
init();
}
public RoundedCornersSmartImageView(Context context, AttributeSet attrs) {
super(context, attrs);
init();
}
public RoundedCornersSmartImageView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
init();
}
#Override
public void onDraw(Canvas canvas) {
Drawable dr = getDrawable();
if (dr != null) {
mRect.set(dr.getBounds());
getImageMatrix().mapRect(mRect);
mRect.offset(getPaddingLeft(), getPaddingTop());
mClip.reset();
mClip.addRoundRect(mRect, RADIUS, RADIUS, Path.Direction.CCW);
canvas.clipPath(mClip);
super.onDraw(canvas);
}
}
public void setRadius(int radius){
this.RADIUS = radius;
}
private void init(){
mRect = new RectF();
mClip = new Path();
}
}
USAGE
in your layout file your SmartimageView should look like this
<your.package.path.RoundedCornersSmartImageView
android:id="#+id/list_image"
android:layout_width="60dip"
android:layout_height="60dip"
android:src="#drawable/profile_anonyme_thumb"/>
..and init the view in your code this way
RoundedCornersSmartImageView thumb_image=(RoundedCornersSmartImageView) findViewById(R.id.list_image);
thumb_image.setRadius(4);
//SmartImageView methode
thumb_image.setImageUrl(bla.MY_THUMB_URL));
Edit your radius for a round image ..

PorterDuff.Mode equivalent for edge fading

I want to programatically render the edge fading of a TextView. By which mode I can create a true alpha gradient?
A real edge fading should smoothly reduce the transparency (no overlay gradient hack) from 1.0 to 0.0 so that the top view fade into background view.
#Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
int y = 0;
int height = 300;
int width = getWidth();
LinearGradient shader = new LinearGradient(width / 2, y, width / 2, y + height, 0xff000000, 0x0000000, Shader.TileMode.CLAMP);
Paint p = new Paint();
p.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.XXX)); // Which mode works?
p.setShader(shader);
canvas.drawRect(0, y, width, y + height, p);
}
I tried all the combinations and none of them worked? Is it impossible to do so?

Here is my solution with an ImageView.
I use a GradientDrawable for the alpha.
Activity:
#Override
protected void onCreate (Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
getWindow().setBackgroundDrawableResource(R.drawable.background);
GradientImageView giv = new GradientImageView(this);
giv.setImageResource(R.drawable.bttf);
giv.setScaleType(ImageView.ScaleType.CENTER_CROP);
setContentView(giv);
}
class GradientImageView extends ImageView
{
Drawable mDrawableMask;
Paint mPaintMask;
Bitmap mOriginal, mBitmapMask;
Canvas mCanvasOriginal, mCanvasMask;
public GradientImageView (final Context context)
{
super(context);
if (android.os.Build.VERSION.SDK_INT >= 11)
setLayerType(View.LAYER_TYPE_SOFTWARE, null);
mDrawableMask = getResources().getDrawable(R.drawable.gradient);
mPaintMask = new Paint();
mPaintMask.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.DST_OUT));
}
protected void setMask (Drawable mask)
{
mDrawableMask = mask;
mBitmapMask = null;
}
#Override
protected void onDraw (final Canvas canvas)
{
if (mOriginal == null)
{
mOriginal = Bitmap.createBitmap(getWidth(), getHeight(), Bitmap.Config.ARGB_8888);
mCanvasOriginal = new Canvas(mOriginal);
}
super.onDraw(mCanvasOriginal);
if (mBitmapMask == null)
{
mBitmapMask = Bitmap.createBitmap(getWidth(), getHeight(), Bitmap.Config.ARGB_8888);
mCanvasMask = new Canvas(mBitmapMask);
mDrawableMask.setBounds(0, 0, getWidth(), getHeight());
mDrawableMask.draw(mCanvasMask);
}
canvas.drawBitmap(mOriginal, 0, 0, null);
canvas.drawBitmap(mBitmapMask, 0, 0, mPaintMask);
}
}
gradient.xml
<?xml version="1.0" encoding="utf-8"?>
<gradient
android:angle="-90"
android:centerColor="#android:color/transparent"
android:centerY="0.5"
android:endColor="#android:color/black"
android:startColor="#android:color/transparent" />
values.xml
<drawable name="background">#FF0000</drawable>
The result (activity background is Red)
