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。

如果不确定的:

((ProgressBar)findViewById(R.id.progressBar))
    .getIndeterminateDrawable()
    .setColorFilter(Color.RED, PorterDuff.Mode.SRC_IN);

更改进度条的前景和背景颜色的最简单的方法是

<ProgressBar
                        style="@android:style/Widget.ProgressBar.Horizontal"
                        android:id="@+id/pb_main"
                        android:layout_width="match_parent"
                        android:layout_height="8dp"
                        android:progress="30"
                        android:progressTint="#82e9de"
                        android:progressBackgroundTint="#82e9de"
                        />

只需添加

                        android:progressTint="#82e9de" //for foreground colour
                        android:progressBackgroundTint="#82e9de" //for background colour

简单的使用方法:

PorterDuff.Mode mode = PorterDuff.Mode.SRC_IN;
if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.GINGERBREAD_MR1) {
    mode = PorterDuff.Mode.MULTIPLY;
}

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    progressBar.setProgressTintList(ColorStateList.valueOf(Color.RED));
    progressBar.setProgressBackgroundTintList(ColorStateList.valueOf(Color.RED));
} else {
    Drawable progressDrawable;
    progressDrawable = (progressBar.isIndeterminate() ? progressBar.getIndeterminateDrawable() : progressBar.getProgressDrawable()).mutate();
    progressDrawable.setColorFilter(context.getResources().getColor(Color.RED), mode);
    progressBar.setProgressDrawable(progressDrawable);
}

将此自定义样式应用于进度条。

<style name="customProgress" parent="@android:style/Widget.ProgressBar.Small">
        <item name="android:indeterminateDrawable">@drawable/progress</item>
        <item name="android:duration">40</item>
        <item name="android:animationCache">true</item>
        <item name="android:drawingCacheQuality">low</item>
        <item name="android:persistentDrawingCache">animation</item>
    </style>

@drawable / progress.xml -

<?xml version="1.0" encoding="utf-8"?>
<animated-rotate xmlns:android="http://schemas.android.com/apk/res/android"
    android:drawable="@drawable/spinner_white"
    android:pivotX="50%"
    android:pivotY="50%" />

使用此类型的图像作为进度条。

为了获得更好的效果，您可以使用多个进度图像。请不要犹豫使用图像，因为Android平台本身使用图像作为进度条。 代码是从sdk中提取的:)

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"/>
