Create circle button with custom background image - android

So I have a background texture (image) that I put on all of my buttons. I want to create a circular button with an icon that retains this background texture.
So far, I have noticed it isn't supported to do this on the shape side:
<shape android:shape="rectangle">
<solid android:color="#drawable/myTexture" /> <!-- this isn't supported -->
</shape>
Lastly I would otherwise try to use <layer-list>, however as I stated above, I need to still crop the texture to my shape I'm creating.
Is the only way to do this to make my own circular images that combine the background texture and the button icon? This seems a bit excessive, as I would think there should be a programmatic way to accomplish this, but I could be wrong.
Here is an example of what I mean above:
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/myTexture" />
<item>
<shape android:shape="rectangle">
<corners android:radius="40dp" />
<size
android:height="80dp"
android:width="80dp" />
<solid android:color="#color/black" />
</shape>
</item>
</layer-list>
In the picture bellow: black is the circle shape, silver is the texture/image (black for contrast)

I haven't solved the programmatic way, but I did end up creating new graphics that combined the icon and the background texture. Using this singular image, I was able to create circular ImageButton's.

rounded view's corners android, NOT round background

I know how to give round borders using XML in Android. I thought it would be cool to make the radius of one corner of my textView excessively large. The problem is, the text keep spilling out. Can I make my textview have a TRULY round corner? (Not just the background). If this was CSS this would be so easy. I am new to Android.
So in terms of CSS, I want to set my overflow to hidden so to speak.
Please help me.
In short, no. All Views are rectangular and fit in bounding boxes.
The best way to achieve rounded corners is the way you mention; using a shape drawable with corner radius set as the background to your TextView.
Like ataulm said, all Views are rectangular.
Create a shape drawable allows you to create a background with rounded corners. You'd have to use padding to make sure the text doesn't clip in certain areas.
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#ffffffff"/>
<stroke android:width="4dp"
android:color="#ff0000"/>
<padding android:left="4dp"
android:top="4dp"
android:right="4dp"
android:bottom="4dp"/>
<corners android:bottomRightRadius="7dp"
android:bottomLeftRadius="7dp"
android:topLeftRadius="7dp"
android:topRightRadius="7dp"/>
</shape>

Shadow round corners Android

how can i make a shadow for round corners? I tried it with views for the bottom, right an the corner, but that works not really :D
I tried this xml for the corner:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<gradient
android:startColor="#404040"
android:centerColor="#DBDBDB"
android:endColor="#color/shadow_end"
android:angle="315"
>
</gradient>
<corners
android:bottomRightRadius="5dp"
android:bottomLeftRadius="0dp"
android:topLeftRadius="0dp"
android:topRightRadius="0dp"/>
</shape>
Is it good to use views for shadows? What you are using?
Thanks for help :)
You can simply draw a 9-patch image with Photoshop drawing the shadows and put it into the drawable folders and set this in your View in xml:
android:background="#drawable/your_9patch_image"
I always do it by using Photoshop. For more details see this: Draw 9-patch
Or you can check in the default Android Studio drawables and see if there's one that you like. Check my answer here: my answer

Android enlarge transparent background of icon drawable

I have many different dynamic icons in my Android app and I would like to put a rectangular frame around all of them. I tried to use LayerDrawable but I think it scales the smaller drawable to the size of the larger one so in the end the icons overlap with the frame instead of within it. (the icon drawables are 64x64 while the frame drawable is 96x96). Is there an way to enlarge the transparent background of the icon drawables to the same size as the frame drawable without scaling the actual icon?
Any help would be appreciated!
You should be able to use a LayerDrawable for this; just tested it myself and it seems to work just fine. Define the frame first, then add another item with the specified insets.
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle">
<solid android:color="#FF0000"/>
</shape>
</item>
<item android:left="20dp" android:top="20dp" android:bottom="20dp" android:right="20dp">
<bitmap android:src="#drawable/ic_launcher"/>
</item>
</layer-list>

Dynamic radial circle in the middle of the screen

Why is it so difficult to make this little thing work? : /
I want to create something like android's lock screen.
I have an XML:
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval" >
<stroke
android:width="#dimen/dp_5"
android:color="#color/black" />
<gradient
android:type="radial"
android:startColor="#color/green"
android:endColor="#color/red"
android:gradientRadius="#dimen/dp_50" />
</shape>
This circle is a background of a TextView, so the following happens:
1. wrap_content creates a little circle in the center of the screen
2. fill_parent creates an elipse taking the whole screen, instead of a circle
In addition I would like to change the startColor and endColor programmatically - Didn't find any documentations\threads which solved this SIMPLE issue.

How to control the gradient on a shape?

I have a screen with a label on top. This label is done with a TextView.
As a background I'd like to have a vertical gradient, starting with color1, changing to color2 and back to color1.
At the moment I have:
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<stroke android:width="1px" android:color="#000000" />
<gradient
android:startColor="#FFFFFFFF"
android:centerColor="#FF8800"
android:endColor="#FFFFFFFF"
android:type="linear"
android:angle="270"
/>
<corners android:radius="10dp"/>
</shape>
My problem is that the centerColor line is too thin. I want it to ocupy all the letters space.
I can't find any way to make the gradient to be faster.
I've already tried to use a layout-list but with no success.
Any idea?
This is a much more different track to follow but have you considered working with 9-patch image files? This will allow you to stretch the parts of the gradient that you wish to and make the centre line as big as needed by segmenting up the background properly.
Here are some great tutorials I have used to learn about them:
