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 的样式属性来更改 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：

我创建了这样的形状（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>

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>

然后创建了这样的样式（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>

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>

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？

我使用以下内容创建自定义进度条。

Fileres/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>

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>

享受！

我在这里使用带有解决方案的不确定进度对话框时遇到了一些麻烦，经过一些工作和反复试验后，我让它工作了。

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：

<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>

你想在哪里显示 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();

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，这对于我需要的东西来说真的太复杂了，所以我没有这样做。

尝试设置：

android:indeterminateDrawable="@drawable/progress"

它对我有用。这也是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>

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>

自定义进度与规模！

<?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android" >
    <item android:duration="150">
        <scale
            android:drawable="@drawable/face_no_smile_eyes_off"
            android:scaleGravity="center" />
    </item>
    <item android:duration="150">
        <scale
            android:drawable="@drawable/face_no_smile_eyes_on"
            android:scaleGravity="center" />
    </item>
    <item android:duration="150">
        <scale
            android:drawable="@drawable/face_smile_eyes_off"
            android:scaleGravity="center" />
    </item>
    <item android:duration="150">
        <scale
            android:drawable="@drawable/face_smile_eyes_on"
            android:scaleGravity="center" />
    </item>

</animation-list>

我做你的代码。我可以运行，但我需要修改两个地方：

  1. name="android:indeterminateDrawable"代替android:progressDrawable

  2. 修改名称 attrs.xml ---> styles.xml

然后打电话

customProgressBar = new CustomProgressBar (Activity, true);
customProgressBar .show();

我不确定，但在这种情况下，您仍然可以使用完整的自定义 AlertDialog，方法是在警报对话框中设置单独的布局文件，并使用上述代码的一部分为您的 imageview 设置动画，也应该这样做！
