Reading the limited documentation that Google has provided, I get the feeling that it is possible to change the look (drawable) of a ProgressBar/ProgressDialog by simply creating a new style an assigning it to the style property of the ProgressBar. But I cannot get this to work properly. Here is what I did so far:
I created a shape like this (mp2.xml)
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="ring"
android:innerRadiusRatio="4"
android:thicknessRatio="4"
android:useLevel="false">
<size android:width="50dip" android:height="50dip" />
<gradient android:type="sweep" android:useLevel="false" android:startColor="#300000ff" android:centerColor="#500000ff" android:endColor="#ff0000ff" />
</shape>
then created an animation (mp3.xml) like this:
<?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android" android:oneshot="false">
<item android:duration="70">
<rotate xmlns:android="http://schemas.android.com/apk/res/android" android:drawable="@drawable/mp2" android:pivotX="50%" android:pivotY="50%" android:fromDegrees="0" android:toDegrees="30" android:repeatCount="1" />
</item>
<item android:duration="70">
<rotate xmlns:android="http://schemas.android.com/apk/res/android" android:drawable="@drawable/mp2" android:pivotX="50%" android:pivotY="50%" android:fromDegrees="30" android:toDegrees="60" android:repeatCount="1" />
</item>
<item android:duration="70">
<rotate xmlns:android="http://schemas.android.com/apk/res/android" android:drawable="@drawable/mp2" android:pivotX="50%" android:pivotY="50%" android:fromDegrees="60" android:toDegrees="90" android:repeatCount="1" />
</item>
<item android:duration="70">
<rotate xmlns:android="http://schemas.android.com/apk/res/android" android:drawable="@drawable/mp2" android:pivotX="50%" android:pivotY="50%" android:fromDegrees="90" android:toDegrees="120" android:repeatCount="1" />
</item>
<item android:duration="70">
<rotate xmlns:android="http://schemas.android.com/apk/res/android" android:drawable="@drawable/mp2" android:pivotX="50%" android:pivotY="50%" android:fromDegrees="120" android:toDegrees="150" android:repeatCount="1" />
</item>
<item android:duration="70">
<rotate xmlns:android="http://schemas.android.com/apk/res/android" android:drawable="@drawable/mp2" android:pivotX="50%" android:pivotY="50%" android:fromDegrees="150" android:toDegrees="180" android:repeatCount="1" />
</item>
<item android:duration="70">
<rotate xmlns:android="http://schemas.android.com/apk/res/android" android:drawable="@drawable/mp2" android:pivotX="50%" android:pivotY="50%" android:fromDegrees="180" android:toDegrees="210" android:repeatCount="1" />
</item>
<item android:duration="70">
<rotate xmlns:android="http://schemas.android.com/apk/res/android" android:drawable="@drawable/mp2" android:pivotX="50%" android:pivotY="50%" android:fromDegrees="210" android:toDegrees="240" android:repeatCount="1" />
</item>
<item android:duration="70">
<rotate xmlns:android="http://schemas.android.com/apk/res/android" android:drawable="@drawable/mp2" android:pivotX="50%" android:pivotY="50%" android:fromDegrees="240" android:toDegrees="270" android:repeatCount="1" />
</item>
<item android:duration="70">
<rotate xmlns:android="http://schemas.android.com/apk/res/android" android:drawable="@drawable/mp2" android:pivotX="50%" android:pivotY="50%" android:fromDegrees="270" android:toDegrees="300" android:repeatCount="1" />
</item>
<item android:duration="70">
<rotate xmlns:android="http://schemas.android.com/apk/res/android" android:drawable="@drawable/mp2" android:pivotX="50%" android:pivotY="50%" android:fromDegrees="300" android:toDegrees="330" android:repeatCount="1" />
</item>
<item android:duration="70">
<rotate xmlns:android="http://schemas.android.com/apk/res/android" android:drawable="@drawable/mp2" android:pivotX="50%" android:pivotY="50%" android:fromDegrees="330" android:toDegrees="360" android:repeatCount="1" />
</item>
</animation-list>
then created a style (attrs.xml) like this:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style parent="@android:style/Widget.ProgressBar" name="customProgressBar">
<item name="android:progressDrawable">@anim/mp3</item>
</style>
</resources>
and the in my main.xml I have set the style like this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent" android:drawingCacheQuality="high">
<ProgressBar android:id="@+id/ProgressBar01"
android:layout_width="wrap_content"
android:layout_height="wrap_content" style="@style/customProgressBar"/>
</LinearLayout>
But it still shows the same drawable as before. What am I doing wrong?
I used the following for creating a custom progress bar.
File
res/drawable/progress_bar_states.xml
declares the colors of the different states:And the code inside your layout xml:
Enjoy!
Try setting:
It worked for me. Here is also the code for progress.xml:
I'm not sure but in this case you can still go with a complete customized AlertDialog by having a seperate layout file set in the alert dialog and set the animation for your imageview using part of your above code that should also do it!
I was having some trouble using an Indeterminate Progress Dialog with the solution here, after some work and trial and error I got it to work.
First, create the animation you want to use for the Progress Dialog. In my case I used 5 images.
../res/anim/progress_dialog_icon_drawable_animation.xml:
Where you want to show a ProgressDialog:
This solution is really simple and worked for me, you could extend ProgressDialog and make it override the drawable internally, however, this was really too complicated for what I needed so I did not do it.
Your style should look like this:
Custom progress with scale!
