Place Circular ImageView on the Edge of another Circular ImageView

I wan to place Small ImageView on the anchor of CircularView just like below image
My Code is
<FrameLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<com.hey.heypickup.UI.UICircularImage xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/contct_imgpic"
android:layout_width="55dp"
android:layout_height="55dp"
android:layout_margin="5dp"
android:layout_weight="0.04"
android:padding="10dp"
app:line_color="#color/colorPrimary"
app:line_color_press="#color/green"
android:src="#drawable/ph_1"
app:line_width="1dp"
app:padding="0dp"/>
<ImageView
android:layout_width="10dp"
android:layout_height="10dp"
android:layout_gravity="bottom|end"
android:src="#drawable/ic_phone_black"
/>
</FrameLayout>
Result of above code:
but the Second imageview not appearing at the achor of circularImageView?
Can we achieve this without using floating action button ?
if yes then how ?

Since your second image is overlapping the first image,
I think it's because your ImageView has a wrap_content height and width. You should make it a fix size, and try it out because if your ic_dialog_email image is large enough then it will take entire space and might overlap the first image.
Would you make height and width fix and try again? For example, make it 15dp each and take a look. Also remove that margin from ImageView along with that change.
You'll just need to trial and check the exact size your need for the second image along with required margin to position itself correctly as per your UI requirements

Big Imageview Loaded As Small - Not Taking Full Parent

I'm loading a big drawable, to an image view, the imageview is both wrap_content, and in the center inside a RelativeLayout.
I'm loading the drawable using Picasso library .
What to expect : Getting loaded just like the preview (in the preview it's correct ) .
What's happening : Drawable getting resized a lot, ex : it's 100, after loading it's 2, that's pretty small .
What I've tried : Getting device width/height dpi, and use them to resize the image, because i'm getting warning that the image is big (using the max as resize, or the screen height/width, i'm getting the same result ) .

try this one bro.
android scaleType = "fitXY"
<ImageView
android:id="#+id/grid_item_image"
android:layout_width="100dp"
android:scaleType="fitXY"
android:layout_gravity="center_horizontal"
android:foregroundGravity="center"
android:layout_height="100dp"/>

This might help
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:adjustViewBounds="true"/>

Android ImageView dynamic ScaleType

I have an Android Activity with an ImageView.
I put the ScaleType of the imageview on CENTER_CROP, so the image itself would not stretch.
<ImageView
android:id="#+id/imgView"
android:layout_width="fill_parent"
android:layout_height="135dp"
android:scaleType="centerCrop"
android:src="#drawable/capture" />
The image that's loaded at first does what I expect, it's cropped to the center, filling the whole ImageView.
Now, if I set the image of the ImageView programatically,
imgView.setImageBitmap(b)
imgView.setScaleType(ImageView.ScaleType.CENTER_CROP);
The picture gets displayed, but it's completely stretched out to fill the ImageView...
AdjustViewBounds has no effect what so ever, nor does anything else.
The difference between the working XML and the not-working java code is that in XML I'm putting the image as a resource, and the code is putting a Drawable in the ImageView from a web-service...
Does anyone have an idea to the solution?

I am not sure but android:scaleType="fitXY" or android:scaleType="fitCenter" may be the solution of your problem.

I solved this by using the original image from my camera-intent. For some reason, all thumbnail bitmaps were stretched out and in landscape mode.

How to create an ImageView that fills the parent height and displays an Image as big as possible?

I have an ImageView that is defined in the following way:
<ImageView
android:id="#+id/cover_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_below="#id/title"
android:layout_above="#id/divider"
android:adjustViewBounds="true"
android:src="#drawable/image_placeholder"
android:scaleType="fitStart"/>
Now after downloading a new bitmap I change the drawable. The image now appears in the top left corner of the ImageView. Is there a way to have the image fill up the whole height that is possible and then adjust the width of the view to enable scaling the image without changing the ascpect ratio?
The image fills up all the space on a standard screen but on a WVGA Resolution the image takes only about half of the actual height of the ImageView.

If I'm understanding you correctly, what you need to use is the centerCrop scaleType. fitStart scales the image proportionally, but neither the width nor height will exceed the size of the view, and the image will, as you said, have a top|left gravity.
Using centerCrop scales the image proportionally, but causes the shortest edge of the image to match the size of the view, and if there is additional data on the long side that does not fit, it is simply cropped off. The gravity is, of course, center. The below worked for me:
<ImageView
android:src="#drawable/image_placeholder"
android:id="#+id/cover_view"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:scaleType="centerCrop"
/>

You can change scale type to fitXY via call to
imageView.setScaleType(ScaleType.FIT_XY);

simply do it in xml like
android:scaleType="fitXY"

Basically the answer here is that there is no predefined value for what you are trying to achieve. The solution is to create a Matrix that fits to your needs and call setImageMatrix(matrix) on your ImageView.

Android image scaling and alignment

I'm trying to show an image scaled while preserving its aspect ratio, but at the same time align it to the bottom.
Using android:scaleType="FitXY" causes the image to be centered vertically and horizontally, so it doesn't get aligned to the bottom.
Using "FitEnd" causes the image to be aligned to the bottom right corner, so it isn't centered horizontally.
Is there any way to get around this? Maybe using some matrix to scale it (scaleType="matrix")?
EDIT: To clarify a bit on what it is I want exactly...
I have an ImageView, whose layout (location, size, gravity, etc.) I can't change. I want to load a bitmap as its source image, but have that bitmap get scaled to the ImageView's size (preserving the aspect ratio of the bitmap) and then aligned to the ImageView's bottom.
EDIT: After trying everything I could think of (and everything that was suggested here), we ended up sub-classing ImageView and doing the scaling/translation ourselves in onDraw.

Try using android:scaleType="centerInside" instead of fitXY.
Layout being used in a Blrfl Labs application to scale an image to fit the area the layout gives it without hosing up the aspect ratio:
<ImageView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_weight="1.0"
android:gravity="center"
android:src="#drawable/blah_blah_blah"
android:scaleType="centerInside"
android:adjustViewBounds="false"
/>

You can use
android:layout_centerHorizontal="true"
android:scaleType="fitEnd"
if your ImageView is inside a RelativeLayout.

Untested, but try adding:
android:layout_gravity="bottom|center_horizontal"
to your ImageView along with FitXY scaling.
