I started porting my app into lollipop. I was able to theme the whole app to a particular color I like but I can't change the color of the ProgressDialog which is always green. Is there any way to do this?
You have to find the asset and change its color with photoshop, or create a new asset and use that as progress dialog.
The new asset can be created like :
<?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="76dip" android:height="76dip" />
<gradient android:type="sweep" android:useLevel="false"
android:startColor="#447a29"
android:endColor="#447a29"
android:angle="0"
/>
</shape>
and call this progress.xml for example then use it like this :
<ProgressBar
android:id="#+id/ProgressBar01"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background ="#xml/progress">
and you have only to change the start and end color to make it how you want it

I have a normal progressBar, but I need the progress to move from right to left instead of left to right.
I've tried using
android:layoutDirection="rtl"
and
android:layoutDirection="ltr"
even tried making a custom drawable for it too, made a progress.xml
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
android:pivotX="50%"
android:pivotY="50%"
android:fromDegrees="-270"
android:toDegrees="270"
android:duration = "5000">
<shape
android:shape="ring"
android:innerRadiusRatio="3"
android:thicknessRatio="8"
android:useLevel="false">
<size
android:width="20dp"
android:height="20dp" />
<gradient
android:type="sweep"
android:useLevel="false"
android:startColor="#color/white"
android:endColor="#00ffffff"
android:angle="90"/>
</shape>
</rotate>
still not working
Please I need an idea of how to handle this.
Thank you in advance.
Try flipping your ProgressBar Simply by setting
android:scaleX="-1"
Try adding the following flag to your XML, I don't think you need a custom drawable. This should do the trick. What I mean is to add it your ProgressBar XML
android:rotation="180"
<ProgressBar
android:layout_width="match_parent"
android:layout_height="match_parent"
android:rotation="180"
/>
Single progress bar is quite old fashioned. I am trying to make a double ring
circular progress bar.
I have been adding two shapes inside the XML code by it gives error.
<?xml version="1.0" encoding="utf-8" ?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
android:fromDegrees="0"
android:pivotX="50%"
android:pivotY="50%"
android:toDegrees="360">
<shape android:shape="ring" android:innerRadiusRatio="4"
android:thicknessRatio="4" android:useLevel="false">
<size android:width="76dip" android:height="76dip" />
<gradient android:type="sweep" android:useLevel="false"
android:startColor="#396338"
android:endColor="#00FF00"
android:angle="0" />
</shape>
</rotate>
Current progress bar:
But I want to make something like this:
why don't you try to use two progressbar where outer progressbar's value can be used by inner progressbar simultaneously
What I did..
<item>
<rotate
android:fromDegrees="40"
android:toDegrees="20"
android:pivotX="25%"
android:pivotY="50%" >
<shape
android:shape="line"
android:top="1dip" >
<stroke
android:width="1dip"
android:color="#FF0000" />
</shape>
</rotate>
</item>
It rotates but doesn't bend. It needs to be bent to form an arc like shape
Any Idea?
You can draw a ring shape, rotate it based on your preference and use it with ProgressBar as progressDrawable with a set progress.
drawable.xml
<?xml version="1.0" encoding="utf-8"?>
<rotate
xmlns:android="http://schemas.android.com/apk/res/android"
android:fromDegrees="150"
android:toDegrees="150">
<shape
android:shape="ring"
android:thickness="10dp"
android:innerRadius="20dp"
android:useLevel="true"><!-- this line fixes the issue for lollipop api 21 -->
<solid android:color="#color/colorPrimary"/>
</shape>
</rotate>
layout.xml
<ProgressBar
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="120dp"
android:layout_height="120dp"
android:progressDrawable="#drawable/widget_arc"
android:indeterminate="false"
android:max="100"
android:progress="67"
/>
You can set the progress dinamically and also easy to animate it
*Use dimen res values
I am using a circular ProgressBar in my Activty.
My Problem is that its color isnt changing properly where only BG color is Changing.
So how can I change the color of ProgressBar without BG.
I tried this thread- How to change default color of progress bar?
http://i.stack.imgur.com/DEpyM.jpg
You can do all in xml files
After some search I got the answer :
you progress bar code :
<ProgressBar
android:id="#+id/progressBar"
style="?android:attr/progressBarStyleLarge"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:max="100"
android:indeterminateDrawable="#drawable/progress"
/>
and the progress drawable is consisting of a rotating ring has a gradiant color of your choise like this :
<?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="76dip" android:height="76dip" />
<gradient android:type="sweep" android:useLevel="false"
android:startColor="#007700"
android:endColor="#115511"
android:angle="0"
/>
</shape>
</rotate>
just like this , please rate this answer :)
Better way (using AppCompat libs):
final int color = Color.WHITE; // Or any other one
final ProgressBar progressBar= (ProgressBar) findViewById(R.id.progress_bar);
DrawableCompat.setTint(progressBar.getIndeterminateDrawable(), color);
When I add horizontal ProgressBar it behaves as expected -- I set the progress value and it shows it.
However when I add ProgressBar (circular) it spins. And that's it. In such form it is more "please wait" indicator, that any progress bar, because progress value is not shown.
So my question is (assuming Progress in name means progress) -- how to stop spinning and shows progress value? For example if I set max to 100, and value to 50 I would expect to see half-circle arc.
In other words how to make circular ProgressBar to behave like horizontal ProgressBar, with only exception of the shape?
I know that this is an old post but I ran into the same issue and I make it work.
It is actually easier than you think, you have to set a custom progress in an xml file inside your drawable folder and handle the attributes "fromDegrees" and "toDegrees" from the < rotate > tag:
This is the code for custom_progress.xml (you can customize yours as you like but you must not modify "fromDegrees" and "toDegrees")
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#android:id/background">
<shape
android:innerRadiusRatio="2.3"
android:shape="ring"
android:useLevel="false"
android:type="sweep"
android:thicknessRatio="15.0">
<solid android:color="#0099ff"/>
</shape>
</item>
<item android:id="#android:id/progress">
<rotate
android:pivotX="50%"
android:pivotY="50%"
android:fromDegrees="-90"
android:toDegrees="-90">
<shape
android:innerRadiusRatio="2.3"
android:shape="ring"
android:angle="0"
android:type="sweep"
android:thicknessRatio="15.0">
<solid android:color="#e0e0e0"/>
</shape>
</rotate>
</item>
</layer-list>
And for your progress bar you have to set this attributes:
<ProgressBar
android:id="#+id/progressbar"
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="100dp"
android:layout_height="100dp"
android:indeterminate="false"
android:max="100"
android:progress="20"
android:progressDrawable="#drawable/custom_progress" />
What is happening here is that the progress will start in degree -90 which for me is the top side of the progress bar view and towards the right and it will continue towards the same degree, this will make the view progress to start and end in the same degree.
NOTE:
If you set 0 for both "fromDegrees" and "toDegrees" the progress will start from the right side of the circle.
Hope it helps people with the same requirement.
Since Api 21 you can do something like that: Assuming that your ProgressBar defind this way:
<ProgressBar xmlns:android="http://schemas.android.com/apk/res/android"
style="?android:attr/progressBarStyleLarge"
android:id="#+id/progress_bar"
android:layout_width="#dimen/item_width"
android:layout_height="#dimen/item_height"
android:clickable="false"
android:indeterminate="true"
android:indeterminateDrawable="#drawable/progress"/>
and this is progress.xml:
<shape
android:innerRadiusRatio="3"
android:shape="ring"
android:thicknessRatio="8"
android:useLevel="false" >
<size
android:height="76dip"
android:width="76dip" />
<gradient
android:angle="0"
android:endColor="#color/colorGrayText"
android:startColor="#android:color/transparent"
android:type="sweep"
android:useLevel="false" />
</shape>
Now you can do this on your ProgressBar:
ProgressBar progressBar = (ProgressBar) findViewById(R.id.progress_bar);
if (progressBar != null) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
RotateDrawable rotateDrawable = (RotateDrawable) progressBar.getIndeterminateDrawable();
rotateDrawable.setToDegrees(0);
}
}
Like toadzky commented, there's no baked-in method. You might try this ProgressWheel. If nothing else, it should give you idea of how to implement it.
For determinate progress bar means the progress bar which doesn't keep on rotating and user can set a fixed percentage over that.
<ProgressBar
android:id="#+id/pb_sharpness"
style="#style/Widget.AppCompat.ProgressBar.Horizontal"
android:layout_width="#dimen/dp_50"
android:layout_height="#dimen/dp_50"
android:layout_marginTop="#dimen/dp_16"
android:indeterminate="false"
android:max="100"
android:progressDrawable="#drawable/custom_progress_bar"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
For adding drawable to above progress bar
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#android:id/background">
<shape
android:innerRadiusRatio="2.3"
android:shape="ring"
android:useLevel="false"
android:type="sweep"
android:thicknessRatio="15.0">
<solid android:color="#color/white_color"/>
</shape>
</item>
<item android:id="#android:id/progress">
<rotate
android:pivotX="50%"
android:pivotY="50%"
android:fromDegrees="180"
android:toDegrees="0"
>
<shape
android:innerRadiusRatio="2.3"
android:shape="ring"
android:angle="0"
android:type="sweep"
android:thicknessRatio="15.0">
<gradient
android:startColor="#color/color_5646F3"
android:endColor="#color/color_ED88FE" />
</shape>
</rotate>
</item>
You can access the visibility property of the progress bar and set it to invisible when you need it to be invisible like this
ProgressBar progressBar = view.findViewById<ProgressBar>(R.id.progressbar)
progressBar.visibility = ProgressBar.INVISIBLE
