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

Adjust ImageView width according to height

I am trying to make a simple LinearLayout composed of an ImageView and TextView.
The ImageView should scale to match the LinearLayout height and not lose proportions while doing so.
This is the xml I currently have.
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<ImageView
android:id="#+id/logo"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:adjustViewBounds="true"
android:background="#CCCCCC"
android:scaleType="fitCenter"
android:src="#drawable/strip" />
<TextView
android:id="#+id/logoText"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ellipsize="marquee"
android:singleLine="true"
android:text="what an awesome text"
android:textSize="18sp" />
</LinearLayout>
Using the above xml, the result is that the ImageView height will indeed match the LinearLayout height and it's width will be the same as the src image but the rendered image will scale properly and center, but this leaves the ImageView itself filling about 90% of the Layout's width as it's the src image width, leaving no space for the TextView.
I just would like to scale the ImageView to match the parent's height and it's width should be just as much needed to scale it proportionately.

Add a linear layout on the image view. Just the image view and nothing else. :) hope it helps
EDIT 1: As many of the other answers mentioned Using the layout_weight property will also help resolve this issue.

add weight 1 on imageview so there will be space for the textview

As I mentioned in the comment under your answer post where you cite KISHORE_ZE, it seems to be helpful only with an image of particular size, and on a particular screen density and resolution. So while it looks acceptable on your current device, it might be a mess on a different one. I suggest that you figure out what part of the layout you want to use for the image and use android:weight attributes for your ImageView and TextView to achieve wanted result.

As #KISHORE_ZE said, this solves the problem.
"Put the image view in a linear layout. Just the image view. Nothing else. "

this visual guide is a lot helpful.

in your image view add:
android:scaleType="fitCenter"
or
android:scaleType="fitXY"
whichever suites you.

How do I set the height of an element to the same as another element?

I'm just starting out with android and trying to make a simple user interface.
I'm using TableLayout and each TableRow is supposed to contain an image and several buttons next to it. I set the width and height of the buttons to wrap_content, which is exactly what I want. Now I want the image to have exactly the same height as the buttons. The image is way bigger, so wrap_content doesn't work.
Obviously I can just adjust the dp value of the image height until it fits, but there has to be an easier way and I guess that pretty much defeats the purpose of using wrap_content in the first place...

Set the height of the image to match_parent. Your buttons are doing all the height-sizing work having the wrap_content set. When the row gets sized it uses the button height, as they say "you will be as tall as our content", and then when the image is going to be sized, it will use the available height, as specified before by the buttons. Even if the buttons are smaller than the image, the image will still take the available space.

Try this
<TableLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<TableRow
android:id="#+id/tableRow1"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<ImageView
android:layout_width="wrap_content"
android:layout_height="match_parent" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</TableRow>
</TableLayout>

Android: How do I align textview on a image background that dos not strech in xml

Ok here is the problem...
I have a image background that need some text and additional graphics on it. The background image needs to be in the center of the screen and may not stretch. Here is what i need to do:
The problem is that i need to align the text to the background image.
I've tried to wrap it all into a relative layout - something like this:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/bg_image"
android:layout_centerInParent="true"
android:src="#drawable/member_card"/>
<TextView
android:layout_height="wrap_content"
android:layout_alignLeft="#id/bg_image"
android:text="#string/membercard_info"
android:layout_marginTop="40dp"
/>
<TextView
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_alignLeft="#id/bg_image"
android:layout_marginTop="200dp"
/>
</RelativeLayout>
This will not work since android adds additional padding to the image to avoid it from stretching.
Here is what happens in two different cases:
So how do I align the text to the background image?
I've solved this problem in the past in code by baking it all into one image,- but would like to do this in xml.

If you want to remove padding, you can use manually set it. However, if you want overlapping elements, you generally want to use FrameLayout. Look here: http://mobile.tutsplus.com/tutorials/android/android-sdk_frame-layout/
Set a gravity inside the frame layout to align it.

if you want an ImageView with additional layers drawn on top of that, see this thread: How to maintain multi layers of ImageViews and keep their aspect ratio based on the largest one?

There a padding around the image because you set the imageView size to fill its parent ( using match_parent )
You should try to set it to wrap its content :
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
.../>
EDIT : If your picture is bigger that the screen size, you need to have it scaled keeping the aspect ratio.
To do this, use match_parent in vertical with a scaleType to FIT_CENTER
and keep the wrap_content setting for the width ( since we want the image view left/right bounds stuck to the image content )
<ImageView
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:scaleType="fitCenter"
.../>
Is this better ?

Maintain circle image ratio for button on varying screen resolutions

I have an image button with a background image .png of a circle. I am testing it on different resolution screens and it looks different on every one. Most of them distort the circle shape by stretching it on one dimension.
What is the correct way to handle this? I am familiar with the 3 density levels needed for the highest quality image, but I think the problem is with the layout type attributes on either the image button itself or the parent container.
Snippet from main.xml...
<LinearLayout
android:id="#+id/buttonArea"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1"
android:orientation="vertical"
android:padding="30dp">
<ImageButton
android:id="#+id/button1"
android:background="#drawable/button_inactive"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_gravity="center"/>
</LinearLayout>
removing the layout_weight attribute from the ImageButton fixed most cases, but not all. It seems that the padding is still changing the ratio of the circle. Scale types have no effect. Is it because my image is set as the background and not the src?

I think android:layout_weight="1" in your ImageButton is the cause of this. It will make your ImageButton the same size of your screen, no matter what size the screen is.
Try to remove that attribute. If that doesn't fix your problem, have a look at android:scaleType attribute
<ImageButton
android:id="#+id/button1"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:layout_gravity="center"
android:background="#null"
android:src="#drawable/button_inactive"
android:scaleType="centerInside"/>

You can set the scaleType attribute of your ImageView, to one that keeps the aspect ratio of your image.
They all behave slightly different, so you'll have to use one that suits your needs (CenterInside is a good one to start with).
If this doesn't work, you can always specify set heigh/widths of your image (e.g. layout_width="128dp).
