使用attr非常简单，如果你正在处理多风格的应用程序:

试试这个方法:

在属性attrs.xml下面声明

 <attr name="circularProgressTheme" format="reference"></attr>

将下面的代码粘贴到styles.xml中

 <style name="ProgressThemeWhite" parent="ThemeOverlay.AppCompat.Light">
        <item name="colorAccent">#FF0000</item>
    </style>

    <style name="circularProgressThemeWhite">
        <item name="android:theme">@style/ProgressThemeWhite</item>
    </style>


  <style name="AppTheme" parent="Theme.AppCompat.NoActionBar">

   <item name="circularProgressTheme">@style/circularProgressThemeWhite</item>

 </style>

使用进度条如下所示

  <ProgressBar
        style="?attr/circularProgressTheme"
        android:id="@+id/commonProgress"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:visibility="visible"/>

对于水平风格的ProgressBar，我使用:

import android.widget.ProgressBar;
import android.graphics.drawable.GradientDrawable;
import android.graphics.drawable.ClipDrawable;
import android.view.Gravity;
import android.graphics.drawable.Drawable;
import android.graphics.drawable.LayerDrawable;

public void setColours(ProgressBar progressBar,
                        int bgCol1, int bgCol2, 
                        int fg1Col1, int fg1Col2, int value1,
                        int fg2Col1, int fg2Col2, int value2)
  {
    //If solid colours are required for an element, then set
    //that elements Col1 param s the same as its Col2 param
    //(eg fg1Col1 == fg1Col2).

    //fgGradDirection and/or bgGradDirection could be parameters
    //if you require other gradient directions eg LEFT_RIGHT.

    GradientDrawable.Orientation fgGradDirection
        = GradientDrawable.Orientation.TOP_BOTTOM;
    GradientDrawable.Orientation bgGradDirection
        = GradientDrawable.Orientation.TOP_BOTTOM;

    //Background
    GradientDrawable bgGradDrawable = new GradientDrawable(
            bgGradDirection, new int[]{bgCol1, bgCol2});
    bgGradDrawable.setShape(GradientDrawable.RECTANGLE);
    bgGradDrawable.setCornerRadius(5);
    ClipDrawable bgclip = new ClipDrawable(
            bgGradDrawable, Gravity.LEFT, ClipDrawable.HORIZONTAL);     
    bgclip.setLevel(10000);

    //SecondaryProgress
    GradientDrawable fg2GradDrawable = new GradientDrawable(
            fgGradDirection, new int[]{fg2Col1, fg2Col2});
    fg2GradDrawable.setShape(GradientDrawable.RECTANGLE);
    fg2GradDrawable.setCornerRadius(5);
    ClipDrawable fg2clip = new ClipDrawable(
            fg2GradDrawable, Gravity.LEFT, ClipDrawable.HORIZONTAL);        

    //Progress
    GradientDrawable fg1GradDrawable = new GradientDrawable(
            fgGradDirection, new int[]{fg1Col1, fg1Col2});
    fg1GradDrawable.setShape(GradientDrawable.RECTANGLE);
    fg1GradDrawable.setCornerRadius(5);
    ClipDrawable fg1clip = new ClipDrawable(
            fg1GradDrawable, Gravity.LEFT, ClipDrawable.HORIZONTAL);        

    //Setup LayerDrawable and assign to progressBar
    Drawable[] progressDrawables = {bgclip, fg2clip, fg1clip};
    LayerDrawable progressLayerDrawable = new LayerDrawable(progressDrawables);     
    progressLayerDrawable.setId(0, android.R.id.background);
    progressLayerDrawable.setId(1, android.R.id.secondaryProgress);
    progressLayerDrawable.setId(2, android.R.id.progress);

    //Copy the existing ProgressDrawable bounds to the new one.
    Rect bounds = progressBar.getProgressDrawable().getBounds();
    progressBar.setProgressDrawable(progressLayerDrawable);     
    progressBar.getProgressDrawable().setBounds(bounds);

    // setProgress() ignores a change to the same value, so:
    if (value1 == 0)
        progressBar.setProgress(1);
    else
        progressBar.setProgress(0);
    progressBar.setProgress(value1);

    // setSecondaryProgress() ignores a change to the same value, so:
    if (value2 == 0)
        progressBar.setSecondaryProgress(1);
    else
        progressBar.setSecondaryProgress(0);
    progressBar.setSecondaryProgress(value2);

    //now force a redraw
    progressBar.invalidate();
  }

一个调用的例子是:

  setColours(myProgressBar, 
          0xff303030,   //bgCol1  grey 
          0xff909090,   //bgCol2  lighter grey 
          0xff0000FF,   //fg1Col1 blue 
          0xffFFFFFF,   //fg1Col2 white
          50,           //value1
          0xffFF0000,   //fg2Col1 red 
          0xffFFFFFF,   //fg2Col2 white
          75);          //value2

如果您不需要“次要进度”，只需将value2设置为value1。

这就是我所做的。工作。

ProgressBar:

<ProgressBar
            android:id="@+id/progressBar"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_weight="4"
            android:indeterminateDrawable="@drawable/progressdrawable"
           />

progressdrawable.xml: 这里使用渐变来改变你喜欢的颜色。和android:toDegrees="X"增加X的值和进度条快速旋转。减小，旋转速度变慢。根据您的需要定制。

<?xml version="1.0" encoding="utf-8"?>
     <rotate xmlns:android="http://schemas.android.com/apk/res/android"
            android:duration="4000"
            android:fromDegrees="0"
            android:pivotX="50%"
            android:pivotY="50%"
            android:toDegrees="360" >

            <shape
                android:innerRadius="20dp"
                android:shape="ring"
                android:thickness="4dp"
                android:useLevel="false" >
                <size
                    android:height="48dp"
                    android:width="48dp" />

                <gradient
                    android:centerColor="#80ec7e2a"
                    android:centerY="0.5"
                    android:endColor="#ffec7e2a"
                    android:startColor="#00ec7e2a"
                    android:type="sweep"
                    android:useLevel="false" />
            </shape>

        </rotate>

示例:

根据一些建议，你可以指定一个形状和可剪切的颜色，然后设置它。我让它以编程的方式工作。我就是这么做的。

首先确保导入了可绘制库。

进口android.graphics.drawable。*;

然后使用类似于下面的代码;

ProgressBar pg = (ProgressBar)row.findViewById(R.id.progress);
final float[] roundedCorners = new float[] { 5, 5, 5, 5, 5, 5, 5, 5 };
pgDrawable = new ShapeDrawable(new RoundRectShape(roundedCorners, null,null));
String MyColor = "#FF00FF";
pgDrawable.getPaint().setColor(Color.parseColor(MyColor));
ClipDrawable progress = new ClipDrawable(pgDrawable, Gravity.LEFT, ClipDrawable.HORIZONTAL);
pg.setProgressDrawable(progress);   
pg.setBackgroundDrawable(getResources().getDrawable(android.R.drawable.progress_horizontal));
pg.setProgress(45);

这招对我很管用:

<ProgressBar
 android:indeterminateTint="#d60909"
 ... />

我知道我迟到了，但如果你只想改变进度条的颜色，这是最简单的解决方案，在你的主题中，只需添加，

@color - your_color

colorSecondary将改变你整个进程的颜色。
