divide a ring drawable into two equal part in android

i want to have a half drawable ring just like an arc.
i have a code that just creates the ring but i am confused how to make it a half ring.
how do i achieve this half ring drawable?
<shape android:shape="ring"
android:innerRadius="15dp"
android:thickness="20dp"
android:useLevel="false"
xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#color/blue"/>
<size android:height="200dp" android:width="200dp"/>
</shape>
This is the image that exactly looks like what am trying to achieve.

you can create like this
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:end="0dp"
android:left="-500dp">
<shape>
<corners android:radius="500dp" />
<solid android:color="#color/colorPrimary" />
</shape>
</item>
<item
android:end="100dp"
android:bottom="100dp"
android:top="100dp"
android:start="-400dp">
<shape>
<corners android:radius="500dp" />
<solid android:color="#color/white" />
</shape>
</item>
</layer-list>
if you went to perfect view then create svg file for this

XML progressDrawable file leaks, for few objects at time

I have XML progressDrawable file for my ListView. It works well, but I found that if I use one Drawable XML file to make background for few object in one time, it works wrong.
Now I'm just created few XML Drawable files for each item from my ListView.
Now, my solution is like that:
for (int i = 0; i < 3; i++) {
View v1 = getActivity().getLayoutInflater().inflate(R.layout.item_results, null);
ProgressBar bar = v1.findViewById(R.id.MyDonut);
bar.setProgressDrawable(getResources().getDrawable(i==0?R.drawable.circle1:i==1?R.drawable.circle2:R.drawable.circle3));
listView.addHeaderView(v1);
}
Here, the circle1,circle2,circle3 - similar XML Drawable files. I think that my solution is too unflexible.
My circle:
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape
android:shape="ring"
android:thicknessRatio="10"
android:useLevel="false">
<solid android:color="#color/orange" />
</shape>
</item>
<item>
<rotate
android:fromDegrees="270"
android:toDegrees="270"
android:pivotX="50%"
android:pivotY="50%">
<shape
android:shape="ring"
android:thicknessRatio="10"
android:useLevel="true">
<solid android:color="#color/green" />
</shape>
</rotate>
</item>
<item android:left="75dp" android:gravity="center">
<rotate android:pivotX="0%" android:fromDegrees="270" android:toDegrees="270">
<shape
android:shape="line"
android:useLevel="false">
<size android:width="75dp" android:height="75dp"/>
<stroke android:width="3dp" android:color="#color/light"/>
</shape>
</rotate>
</item>
<item android:left="75dp" android:gravity="center">
<rotate android:pivotX="0%" android:fromDegrees="270" android:toDegrees="630">
<shape
android:shape="line"
android:useLevel="false">
<size android:width="75dp" android:height="75dp"/>
<stroke android:width="3dp" android:color="#color/light"/>
</shape>
</rotate>
</item>
item-results just contains:
<ProgressBar
android:progress="0"
android:id="#+id/MyDonut"
android:layout_width="150dp"
android:layout_height="150dp"
android:background="#color/light"
style="?android:progressBarStyleHorizontal"/>
What about the other solutions of this issue?

Finaly, I found a good solution. We can use drawable.mutate() to set the other Drawable, with all properties from parent Drawable.
Documentation: https://developer.android.com/reference/android/graphics/drawable/Drawable#mutate()
It is possible to use this this way:
progressBar.setProgressDrawable(getResources().getDrawable(R.drawable.circle).mutate());

Android layerlist is not working in different mobiles

I want to create a drawable file like the below screenshot.
My drawable xml file:
<?xml version="1.0" encoding="utf-8"?>
<layer-list
xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:top="0px"
android:left="0px"
android:right="0px"
android:bottom="0px">
<shape android:shape="rectangle">
<corners android:radius="#dimen/_6sdp" />
<solid android:color="#color/activeslots"/>
</shape>
</item>
<item
android:top="#dimen/_14sdp"
android:left="#dimen/_12sdp"
android:right="#dimen/_58sdp"
android:bottom="#dimen/_14sdp">
<shape android:shape="oval">
<solid android:color="#color/white"/>
<size android:height="#dimen/_20sdp"
android:width="#dimen/_20sdp"/>
</shape>
</item>
</layer-list>
I created rectangle and oval inside the layer_list. But the issue is it is not working in different mobiles, also the white circle inside the drawable is becomes big after setting height and width.

How to design doted round using android xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<solid
android:color="#D3D3D3"/>
</shape>
above one is single round, how to create two colored round (one inside one) shape using android xml
help me.

This is how i draw a dotted round
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<stroke android:width="1dp" android:color="#0000FF"
android:dashWidth="2dp"
android:dashGap="10dp"/>
</shape>

Use this:
android:shape="ring"
instead of "oval" & then set the inner and outer radius accordingly.

you need the stroke tag:
<stroke
android:width="integer"
android:color="color"
android:dashWidth="integer"
android:dashGap="integer" />
in particular android:dashWidth="integer" and android:dashGap="integer".
The former is the size of each dash line, the latter is the distance between line dashes,
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<solid android:color="#D3D3D3"/>
<stroke android:width="1dp" android:color="#FFFF0000"
android:dashWidth="3dp"
android:dashGap="3dp"/>
</shape>

You can use oval, and create it like this:
<shape android:shape="oval" xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#55FF3300"/>
<size android:height="80dp" android:width="80dp"/>
<stroke android:color="#66FF3300" android:width="10dp"/>
</shape>

Best way to tint my buttons?

I'm currently developing an android app where I use transparent png's as buttons for the user interface.
The buttons look kinda like this:
When the user presses the button I want to automatically tint the non-transparent pixels in the image to a darker color.
Currently I use an xml selector with different drawables for each state. This obviously doesn't scale well since I need to make several versions of each image in photoshop.
Any solutions? I heard that you can use the setColorFilter method on ImageView's to achieve this, but a full explanation would be great!
Thanks!

set this image as source to ImageButton and set ImageButton's state (backgriund) using xml state list, something like this
<?xml version="1.0" encoding="utf-8"?>
<selector
xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true">
<shape
>
<gradient
android:startColor="#android:color/background_light"
android:endColor="#android:color/darker_gray"
android:angle="90"/>
<stroke
android:width="1dp"
android:color="#999999" />
<corners
android:radius="9dp"/>
<padding
android:left="10dp"
android:top="10dp"
android:right="10dp"
android:bottom="10dp"/>
</shape>
</item>
<item android:state_focused="true">
<shape>
<gradient
android:endColor="#android:color/transparent"
android:startColor="#android:color/transparent"
android:angle="270"/>
<stroke
android:width="1dp"
android:color="#989797" />
<corners
android:radius="9dp"/>
<padding
android:left="10dp"
android:top="10dp"
android:right="10dp"
android:bottom="10dp"/>
</shape>
</item>
