Custom Drawable for ProgressBar/ProgressDialog
提问by Sam
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:
阅读 Google 提供的有限文档，我觉得可以通过简单地创建一个新样式并将其分配给 ProgressBar 的 style 属性来更改 ProgressBar/ProgressDialog 的外观（可绘制）。但我无法让它正常工作。这是我到目前为止所做的：
I created a shape like this (mp2.xml)
我创建了一个这样的形状（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:
然后像这样创建了一个动画（mp3.xml）：
<?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:
然后创建了一个这样的样式（attrs.xml）：
<?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:
在我的 main.xml 中，我设置了这样的样式：
<?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?
但它仍然显示与以前相同的可绘制对象。我究竟做错了什么？

I used the following for creating a custom progress bar.
我使用以下内容来创建自定义进度条。
File res/drawable/progress_bar_states.xmldeclares the colors of the different states:
文件res/drawable/progress_bar_states.xml声明了不同状态的颜色：
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@android:id/background">
<shape>
<gradient
android:startColor="#000001"
android:centerColor="#0b131e"
android:centerY="0.75"
android:endColor="#0d1522"
android:angle="270"
/>
</shape>
</item>
<item android:id="@android:id/secondaryProgress">
<clip>
<shape>
<gradient
android:startColor="#234"
android:centerColor="#234"
android:centerY="0.75"
android:endColor="#a24"
android:angle="270"
/>
</shape>
</clip>
</item>
<item android:id="@android:id/progress">
<clip>
<shape>
<gradient
android:startColor="#144281"
android:centerColor="#0b1f3c"
android:centerY="0.75"
android:endColor="#06101d"
android:angle="270"
/>
</shape>
</clip>
</item>
</layer-list>
And the code inside your layout xml:
以及布局 xml 中的代码：
<ProgressBar android:id="@+id/progressBar"
android:progressDrawable="@drawable/progress_bar_states"
android:layout_width="fill_parent" android:layout_height="8dip"
style="?android:attr/progressBarStyleHorizontal"
android:indeterminateOnly="false"
android:max="100">
</ProgressBar>
Enjoy!
享受！

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.
我在使用不确定进度对话框和这里的解决方案时遇到了一些麻烦，经过一些工作和反复试验后，我让它工作了。
First, create the animation you want to use for the Progress Dialog. In my case I used 5 images.
首先，创建要用于“进度对话框”的动画。就我而言，我使用了 5 张图片。
../res/anim/progress_dialog_icon_drawable_animation.xml:
../res/anim/progress_dialog_icon_drawable_animation.xml：
<animation-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/icon_progress_dialog_drawable_1" android:duration="150" />
<item android:drawable="@drawable/icon_progress_dialog_drawable_2" android:duration="150" />
<item android:drawable="@drawable/icon_progress_dialog_drawable_3" android:duration="150" />
<item android:drawable="@drawable/icon_progress_dialog_drawable_4" android:duration="150" />
<item android:drawable="@drawable/icon_progress_dialog_drawable_5" android:duration="150" />
</animation-list>
Where you want to show a ProgressDialog:
要在何处显示 ProgressDialog：
dialog = new ProgressDialog(Context.this);
dialog.setIndeterminate(true);
dialog.setIndeterminateDrawable(getResources().getDrawable(R.anim.progress_dialog_icon_drawable_animation));
dialog.setMessage("Some Text");
dialog.show();
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.
这个解决方案非常简单并且对我有用，您可以扩展 ProgressDialog 并使其在内部覆盖可绘制对象，但是，这对于我所需要的来说真的太复杂了，所以我没有这样做。

Try setting:
尝试设置：
android:indeterminateDrawable="@drawable/progress"
It worked for me. Here is also the code for progress.xml:
它对我有用。这里也是progress.xml的代码：
<?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>

Your style should look like this:
你的风格应该是这样的：
<style parent="@android:style/Widget.ProgressBar" name="customProgressBar">
<item name="android:indeterminateDrawable">@anim/mp3</item>
</style>

i do your code .i can run but i need modify two places:
我做你的代码。我可以运行，但我需要修改两个地方：
name="android:indeterminateDrawable"instead ofandroid:progressDrawablemodify name attrs.xml ---> styles.xml
name="android:indeterminateDrawable"代替android:progressDrawable修改名称 attrs.xml ---> 样式.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!
我不确定，但在这种情况下，您仍然可以通过在警报对话框中设置单独的布局文件来使用完整的自定义 AlertDialog，并使用上述代码的一部分为您的图像视图设置动画！
