Custom CircleImageView border

I'm trying to build a messaging app and I want to know if it's possible to recreate the sender image and name in XML in one shape/View
I want to make a CircleImageView with bent shape like in this picture
The image that i want to recreate
The reason I want it to be one shape is that i want to be able to change the color programatically.
PS:Right now I managed to get close to what I want by putting a TextView behind a CircleImageView.

You can easily create a TextView with a drawable depending on your needs e.g. TextView with drawableLeft, drawableRight, drawableTop, drawableBottom, you can also add a drawablePadding as well as play with gravity, layout_gravity, layout_height for positioning of text vs image.
and then you can use Glide to load the images, you can customize the border as you want:
Glide.with(myFragmentOrActivity)
.load(imageUrl)
.apply(RequestOptions.circleCropTransform())
.into(new CustomTarget<Drawable>(100,100) {
#Override
public void onResourceReady(#NonNull Drawable resource, #Nullable Transition<? super Drawable> transition)
{
left.setCompoundDrawablesWithIntrinsicBounds(null, resource, null, null);
}
#Override
public void onLoadCleared(#Nullable Drawable placeholder)
{
left.setCompoundDrawablesWithIntrinsicBounds(null, placeholder, null, null);
}
});

Using CircledImageView in android wear

I am using the CircledImageView to display the image in the ListView, but I am not getting the image view as circular. Can anyone tell me how to achieve this?

ok got it woking by setting the height and width as wrap content and also providig the radius of the cirlce.
Here is the code working for me.
<android.support.wearable.view.CircledImageView
android:id="#+id/im_action_icons"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
app:circle_border_color="#FFFFFFFF"
app:circle_border_width="2dp"
app:circle_color="#color/blue"
app:circle_radius="23dp" />

Try this short code it works for me:
RoundedBitmapDrawable roundedBitmapDrawable = RoundedBitmapDrawableFactory.create(Activity.this.getResources(), yourbitmap);
roundedBitmapDrawable.setCircular(true);
your imageview.setImageDrawable(roundedBitmapDrawable);
If you use Glide library to download images you can do something like this.
Glide.with(context).load(your image url).asBitmap().placeholder(your default place holder).error(error place holder).into(new BitmapImageViewTarget(your imageview) {
#Override
protected void setResource(Bitmap resource) {
super.setResource(resource);
RoundedBitmapDrawable roundedBitmapDrawable = RoundedBitmapDrawableFactory.create(Activity.this.getResources(), resource);
roundedBitmapDrawable.setCircular(true);
your imageview.setImageDrawable(roundedBitmapDrawable);
}
});
You can also do these thing with Picasso library

ImageSwitcher load images from url

I'm trying to show images from a URL in a ImageSwitcher. I've tried with:
myImageSwitcher.setImageURI(Uri.parse("http://miurl.com/images/foto01.jpg"));
but it said me this "error":
I/System.out﹕ resolveUri failed on bad bitmap uri: http://miurl.com/images/foto01.jpg
Thanks

I know it is late but because I found a better solution for this, would love to share it with all :)
I had to look at the source code of the default ImageSwitcher and know how it works. Whenever we use ImageSwitcher we set a ViewFactory to it. This ViewFactory creates Views which are then used in the ImageSwitcher. Usually we create an ImageView in the ViewFactory. This ImageView is then used in the ImageSwitcher class to draw the view with the image source specified. Below is the setImageResource() method of the ImageSwitcher class.
public void setImageResource(#DrawableRes int resid){
ImageView image = (ImageView)this.getNextView();
image.setImageResource(resid);
showNext();
}
Let's focus on the first and second line of the method.
ImageView image = (ImageView)this.getNextView();
image.setImageResource(resid);
this.getNextView() gets the view from the ViewFactory and casts the view into an ImageView. And then, the Drawable resource is set to it.
Solution
Now, with these information, let's get to the solution! I'm using Volley's NetworkImageView , but you can use Picasso or Glide too! You just have to change the code a bit.
We need to create a custom ImageSwitcher. Here's my code
MyImageSwitcher.java
public class MyImageSwitcher extends ImageSwitcher {
public MyImageSwitcher(Context context) {
super(context);
}
public MyImageSwitcher(Context context, AttributeSet attrs) {
super(context, attrs);
}
public void setImageUrl(String url) {
NetworkImageView image = (NetworkImageView) this.getNextView();
image.setImageUrl(url, AppController.getInstance().getImageLoader());
showNext();
}
}
Notice the setImageUrl() method. We cast the view we get from getNextView() to a NetworkImageView and set the Url to it. If you want to use Picasso, then just cast it into an ImageView and then use Picasso as it needs to be used.
Activity
MyImageSwitcher imageSwitcher = (MyImageSwitcher) findViewById(R.id.imageSwitcher);
imageSwitcher.setFactory(new ViewSwitcher.ViewFactory() {
public View makeView() {
NetworkImageView myView = new NetworkImageView(getApplicationContext());
myView.setScaleType(ImageView.ScaleType.CENTER_CROP);
myView.setLayoutParams(new ImageSwitcher.LayoutParams(imageSwitcher.getLayoutParams()));
return myView;
}
});
If you want to use Picasso, then just use an ImageView.
Layout
<xyz.farhanfarooqui.loadingimages.MyImageSwitcher
android:id="#+id/imageSwitcher"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
AndroidManifest.xml
Don't forget to include android.permission.INTERNET to your AndroidManifest.xml
Done!
Whenever you want to change the image, do it this way,
imageSwitcher.setImageUrl("http://miurl.com/images/foto01.jpg");

I've solucionated this problem using SliderLayot (https://github.com/daimajia/AndroidImageSlider), but I'll try to do with ImageSwitcher too.

I was trying to achieve the same thing when I landed here. I know it's and old question, but since I don't see an answer, I'll tell you the solution that worked for me.
First of all, I downloaded the image/s that I wanted to show in the imageswitcher and return them as a Bitmap using this code:
InputStream in = new java.net.URL(url).openStream();
Bitmap bitmap = BitmapFactory.decodeStream(in);
Then I set the bitmap in the imageswitcher using imageSwitcher.setImageDrawable(new BitmapDrawable(getResources(), bitmap)).
To use java.net.URL(url).openStream(), you'll need to add <uses-permission android:name="android.permission.INTERNET"> to your AndroidManifest.xmlfile.
Have in mind that you could change the download code to make it better (checking for timeouts for example), but this is just a basic solutions to start from.
Another thing about what you were using, I think you can't use setImageURI() to set an internet resource in your ImageSwitcher. Acording to this post, this method is only for content URIs particular to the Android platform (Note that they are talking about an ImageView in that post, but I think the same goes to this case).

How can you use a loading placeholder that is an animated spinner with image loaders like Glide, Picasso etc?

I am trying to insert a generic loading circle as placeholder while an image is being loaded with an image loader library like Glide or Picasso.
I cannot for the life of me find out how you are supposed to create a rotating drawable from xml.
I tried using an AnimationDrawable in XML by creating an animation-list, but it doesn't even show up (not even static).
I just want to have a simple circle that spins all by itself, all in an xml drawable, so I can pass the id as placeholder to my image loader. If that is not possible please tell me now, so I can save a lot of research :)
EDIT: Some code to make it more clear, I need a spinning drawable for this Glide command:
Glide.with(context)
.load(imageUrl)
.into(imageView)
.placeHolder(R.drawable.spinning_loading_placeholder);
While the image is being loaded a placeholder drawable will be shown where the image will later be. I need a drawable that spins itself.

You can add a ProgressBar element to your layout XML, and then display/hide this element as needed. The ProgressBar View is built in and already animated, no custom AnimationDrawable required.

You can use something like this:
Glide.with(mContext).load(imageUrl).asBitmap().centerCrop().into(new BitmapImageViewTarget(vh.avatarImageView) {
#Override
public void onLoadStarted(Drawable placeholder) {
vh.avatarImageView.setImageDrawable(mContext.getResources().getDrawable(R.drawable.ic_placeholder));
}
#Override
public void onLoadFailed(Exception e, Drawable errorDrawable) {
vh.avatarImageView.setImageDrawable(mContext.getResources().getDrawable(R.drawable.ic_failed_download));
}
#Override
protected void setResource(Bitmap resource) {
RoundedBitmapDrawable circularBitmapDrawable =
RoundedBitmapDrawableFactory.create(mContext.getResources(), resource);
circularBitmapDrawable.setCircular(true);
vh.avatarImageView.setImageDrawable(circularBitmapDrawable);
}
});

Changing ImageView source

I have an ImageView with a source image set in the xml using the following syntax:
<ImageView
android:id="#+id/articleImg"
style="#style/articleImgSmall_2"
android:src="#drawable/default_m" />
Now I need to change this image programmatically. What I need to do is delete the old image and add a new one though. What I have done is this:
myImgView.setBackgroundResource(R.drawable.monkey);
It works but I noticed android stacks the new image on top of the old one (dont ask me how I found out it's not relevant for the discussion :). I definitely need to get rid of the old one before setting the new image.
How can I achieve that?

Changing ImageView source:
Using setBackgroundResource() method:
myImgView.setBackgroundResource(R.drawable.monkey);
you are putting that monkey in the background.
I suggest the use of setImageResource() method:
myImgView.setImageResource(R.drawable.monkey);
or with setImageDrawable() method:
myImgView.setImageDrawable(getResources().getDrawable(R.drawable.monkey));
*** With new android API 22 getResources().getDrawable() is now deprecated. This is an example how to use now:
myImgView.setImageDrawable(getResources().getDrawable(R.drawable.monkey, getApplicationContext().getTheme()));
and how to validate for old API versions:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
myImgView.setImageDrawable(getResources().getDrawable(R.drawable.monkey, getApplicationContext().getTheme()));
} else {
myImgView.setImageDrawable(getResources().getDrawable(R.drawable.monkey));
}

You're supposed to use setImageResource instead of setBackgroundResource.

myImgView.setImageResource(R.drawable.monkey);
is used for setting image in the current image view, but if want to delete this image
then you can use this code like:
((ImageView) v.findViewById(R.id.ImageView1)).setImageResource(0);
now this will delete the image from your image view, because it has set the resources value to zero.

get ID of ImageView as
ImageView imgFp = (ImageView) findViewById(R.id.imgFp);
then Use
imgFp.setImageResource(R.drawable.fpscan);
to set source image programatically instead from XML.

Supplemental visual answer
ImageView: setImageResource() (standard method, aspect ratio is kept)
View: setBackgroundResource() (image is stretched)
Both
My fuller answer is here.

Or try this one. For me it's working fine:
imageView.setImageDrawable(ContextCompat.getDrawable(this, image));

If you want to set in imageview an image that is inside the mipmap dirs you can do it like this:
myImageView.setImageDrawable(getResources().getDrawable(R.mipmap.my_picture)

Just write a method for changing imageview
public void setImage(final Context mContext, final ImageView imageView, int picture)
{
if (mContext != null && imageView != null)
{
try
{
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP)
{
imageView.setImageDrawable(mContext.getResources().getDrawable(picture, mContext.getApplicationContext().getTheme()));
} else
{
imageView.setImageDrawable(mContext.getResources().getDrawable(picture));
}
} catch (Exception e)
{
e.printStackTrace();
}
}
}
