阅读Google提供的有限文档，我感觉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）。但我不能让它正常工作。这是我到目前为止所做的：
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>
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>
创建了一个样式（attrs.xml），如下所示：
<?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>
但它仍然显示出与以前相同的可绘制性。我做错了什么？

我使用以下内容创建自定义进度条。
文件res/drawable/progress_bar_states.xml声明不同状态的颜色：
<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>
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！

我在使用不确定进度对话框时遇到了一些问题，经过一些工作和反复试验后我才开始工作。
首先，创建要用于进度对话框的动画。在我的情况下，我使用了5张图片。
<强> ../ RES /动画/ 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>
您要在哪里展示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，你可以扩展ProgressDialog并使其在内部覆盖drawable，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>

你的风格应如下所示：
<style parent="@android:style/Widget.ProgressBar" name="customProgressBar">
<item name="android:indeterminateDrawable">@anim/mp3</item>
</style>

按比例自定义进度！
<?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>
答案 5 :(得分：5)
我做你的代码。我可以运行，但我需要修改两个地方：
name="android:indeterminateDrawable"代替android:progressDrawable
修改名称attrs.xml ---＆gt; styles.xml

我不确定但是在这种情况下你仍然可以通过在警告对话框中设置一个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你的imageview设置动画！
答案 7 :(得分：0)
public class CustomProgressBar {
private RelativeLayout rl;
private ProgressBar mProgressBar;
private Context mContext;
private String color__ = "#FF4081";
private ViewGroup layout;
public CustomProgressBar (Context context, boolean isMiddle, ViewGroup layout) {
initProgressBar(context, isMiddle, layout);
}
public CustomProgressBar (Context context, boolean isMiddle) {
try {
layout = (ViewGroup) ((Activity) context).findViewById(android.R.id.content).getRootView();
} catch (Exception e) {
e.printStackTrace();
}
initProgressBar(context, isMiddle, layout);
}
void initProgressBar(Context context, boolean isMiddle, ViewGroup layout) {
mContext = context;
if (layout != null) {
int padding;
if (isMiddle) {
mProgressBar = new ProgressBar(context, null, android.R.attr.progressBarStyleSmall);
// mProgressBar.setBackgroundResource(R.drawable.pb_custom_progress);//Color.parseColor("#55000000")
padding = context.getResources().getDimensionPixelOffset(R.dimen.padding);
} else {
padding = context.getResources().getDimensionPixelOffset(R.dimen.padding);
mProgressBar = new ProgressBar(context, null, android.R.attr.progressBarStyleSmall);
}
mProgressBar.setPadding(padding, padding, padding, padding);
mProgressBar.setBackgroundResource(R.drawable.pg_back);
mProgressBar.setIndeterminate(true);
try {
color__ = AppData.getTopColor(context);//UservaluesModel.getAppSettings().getSelectedColor();
} catch (Exception e) {
color__ = "#FF4081";
}
int color = Color.parseColor(color__);
// color=getContrastColor(color);
// color__ = color__.replaceAll("#", "");//R.color.colorAccent
mProgressBar.getIndeterminateDrawable().setColorFilter(color, android.graphics.PorterDuff.Mode.SRC_ATOP);
}
}
RelativeLayout.LayoutParams params = new
RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT);
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
rl = new RelativeLayout(context);
if (!isMiddle) {
int valueInPixels = (int) context.getResources().getDimension(R.dimen.padding);
lp.setMargins(0, 0, 0, (int) (valueInPixels / 1.5));//(int) Utils.convertDpToPixel(valueInPixels, context));
rl.setClickable(false);
lp.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
} else {
rl.setGravity(Gravity.CENTER);
rl.setClickable(true);
}
lp.addRule(RelativeLayout.CENTER_IN_PARENT);
mProgressBar.setScaleY(1.55f);
mProgressBar.setScaleX(1.55f);
mProgressBar.setLayoutParams(lp);
rl.addView(mProgressBar);
layout.addView(rl, params);
}
}
public void show() {
if (mProgressBar != null)
mProgressBar.setVisibility(View.VISIBLE);
}
public void hide() {
if (mProgressBar != null) {
rl.setClickable(false);
mProgressBar.setVisibility(View.INVISIBLE);
}
}
}
然后致电
customProgressBar = new CustomProgressBar (Activity, true);
customProgressBar .show();
