相信我，最简单的解决方法就是把这个粘贴到progressBar中:

android:indeterminateTint="@android:color/white"

我是如何在水平ProgressBar中做到的:

    LayerDrawable layerDrawable = (LayerDrawable) progressBar.getProgressDrawable();
    Drawable progressDrawable = layerDrawable.findDrawableByLayerId(android.R.id.progress);
    progressDrawable.setColorFilter(color, PorterDuff.Mode.SRC_IN);

对于水平的ProgressBar，你也可以使用ColorFilter，就像这样:

progressBar.getProgressDrawable().setColorFilter(
    Color.RED, android.graphics.PorterDuff.Mode.SRC_IN);

注意:这将修改应用程序中所有进度条的外观。要只修改一个特定的进度条，请执行以下操作:

Drawable progressDrawable = progressBar.getProgressDrawable().mutate();
progressDrawable.setColorFilter(Color.RED, android.graphics.PorterDuff.Mode.SRC_IN);
progressBar.setProgressDrawable(progressDrawable);

如果progressBar是不确定的，则使用getIndeterminateDrawable()而不是getProgressDrawable()。

因为棒棒糖(API 21)，你可以设置一个进度色调:

progressBar.setProgressTintList(ColorStateList.valueOf(Color.RED));

在新版本的材料设计库中，一个不确定的线性进度指示器似乎可以被制作成多种颜色。

使进度条的动画类型连续可以实现这一点。

在具有此属性的布局中: 应用:indeterminateAnimationType 或者用这个方法编程: setIndeterminateAnimationType ()

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。

android:progressTint="#ffffff"
