Android custom circular ProgressBar direction - android

I have a custom Circular Progressbar. This is the drawable I have for it to be determinate:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#android:id/secondaryProgress">
<shape
android:innerRadiusRatio="6"
android:shape="ring"
android:thicknessRatio="20.0"
android:useLevel="true">
<gradient
android:centerColor="#999999"
android:endColor="#999999"
android:startColor="#999999"
android:type="sweep" />
</shape>
</item>
<item android:id="#android:id/progress">
<rotate
android:fromDegrees="270"
android:pivotX="50%"
android:pivotY="50%"
android:toDegrees="270">
<shape
android:innerRadiusRatio="6"
android:shape="ring"
android:thicknessRatio="20.0"
android:useLevel="true">
<rotate
android:fromDegrees="360"
android:pivotX="50%"
android:pivotY="50%"
android:toDegrees="0" />
<gradient
android:centerColor="?attr/colorAccent"
android:endColor="?attr/colorAccent"
android:startColor="?attr/colorAccent"
android:type="sweep" />
</shape>
</rotate>
</item>
</layer-list>
I want it to show the progress in a clockwise direction, but now it's showing counterclockwise.
How do I change it?


I guess you're using an rtl language? You can force the progress bar to an ltr or clockwise direction by setting the layoutDirection property on your ProgressBar.
<ProgressBar
...
android:layoutDirection="ltr" />


By using latest versions of material design library, you can achieve this:
in the layout with this attribute
app:indicatorDirectionCircular
or programmatically with this method
setIndicatorDirection()
Refer here for more info.


Change this
<rotate
android:fromDegrees="360"
android:pivotX="50%"
android:pivotY="50%"
android:toDegrees="0" />
to
<rotate
android:fromDegrees="0"
android:pivotX="50%"
android:pivotY="50%"
android:toDegrees="360" />


I'm not sure if it will work, but just try to set android:toDegrees="-360" like this :
<rotate
android:fromDegrees="0"
android:pivotX="50%"
android:pivotY="50%"
android:toDegrees="-360" />


you can change rotation on Y axis by 180 degrees
android:rotationY="180"

Android: how to animate a circular ProgressBar with a mask?

I want to create a circular ProgressBar animating within a custom shape, like this:
I already know how to create a basic circular ProgressBar:
<ProgressBar style="#style/Widget.AppCompat.ProgressBar.Horizontal"
android:layout_width="80dp"
android:layout_height="80dp"
android:indeterminate="false"
android:max="6000"
android:progress="0"
android:progressDrawable="#drawable/shape_ring_blue_progress" />
shape_ring_blue_progress.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<rotate
android:fromDegrees="270"
android:pivotX="50%"
android:pivotY="50%"
android:toDegrees="270">
<shape
android:shape="ring"
android:innerRadiusRatio="2.17391304"
android:thicknessRatio="25.0"
android:useLevel="true">
<rotate
android:fromDegrees="0"
android:pivotX="50%"
android:pivotY="50%"
android:toDegrees="360" />
<solid
android:color="#color/style_color_blue" />
</shape>
</rotate>
</item>
</layer-list>
But I have no clue of how to use a more complex shape and a mask like I want to.
Thanks for your help!

Set progressBar.setIndeterminateDrawable() to any drawable file it
will replace your moving loader to the defined moving image.

Custom progress drawable not working on Android Lollipop (API 21) devices

I have a progress drawable which does not work properly on devices running Android Lollipop.

This drawable is used as a background to ProgressView like this:
<ProgressBar
android:id="#+id/circle_progress"
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="70dp"
android:layout_height="70dp"
android:gravity="center"
android:progress="65"
android:indeterminate="false"
android:progressDrawable="#drawable/circle_percentage_drawable"
/>
The renders as a circle drawn to 65% show up on devices running Android M, KitKat, Jellybean. However, if the same code is run on Android Lollipop (API 21) the circle shows as 100%.
Full source code available here: https://github.com/slashrootv200/CircleProgressPercentage

Add android:useLevel=true" in your circular progressbar xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="oval"
android:useLevel="true">

</item>
<item android:id="#android:id/progress">
<rotate
android:fromDegrees="270"
android:pivotX="50%"
android:pivotY="50%"
android:toDegrees="270">

android:innerRadiusRatio="2.5"
android:shape="ring"
android:thicknessRatio="25.0"

Custom Drawable for ProgressDialog

<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
android:pivotX="50%" android:pivotY="50%" android:fromDegrees="0"
android:toDegrees="360">
<shape android:shape="ring" android:innerRadiusRatio="3"
android:thicknessRatio="8" android:useLevel="false">
<size android:width="48dip" android:height="48dip" />
<gradient android:type="sweep" android:useLevel="false"
android:startColor="#4c737373" android:centerColor="#4c737373"
android:centerY="0.50" android:endColor="#ffffd300" />
</shape>
</rotate>
This code creates a circle indicator and it will rotate it to show one color but I want it instead to display multi-colors.
