更改水平进度条颜色(kotlin):

fun tintHorizontalProgress(progress: ProgressBar, @ColorInt color: Int = ContextCompat.getColor(progress.context, R.color.colorPrimary)){
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        progress.progressTintList = ColorStateList.valueOf(color)
    } else{
        val layerDrawable = progress.progressDrawable as? LayerDrawable
        val progressDrawable = layerDrawable?.findDrawableByLayerId(android.R.id.progress)
        progressDrawable?.setColorFilter(color, PorterDuff.Mode.SRC_ATOP)
    }
}

更改不确定的ProgressBar颜色:

fun tintIndeterminateProgress(progress: ProgressBar, @ColorInt color: Int = ContextCompat.getColor(progress.context, R.color.colorPrimary)){
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        progress.indeterminateTintList = ColorStateList.valueOf(color)
    } else {
        (progress.indeterminateDrawable as? LayerDrawable)?.apply {
            if (numberOfLayers >= 2) {
                setId(0, android.R.id.progress)
                setId(1, android.R.id.secondaryProgress)
                val progressDrawable = findDrawableByLayerId(android.R.id.progress).mutate()
                progressDrawable.setColorFilter(color, PorterDuff.Mode.SRC_ATOP)
            }
        }
    }
}

它最终正常地着色pre-lollipop progressBars

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);

ProgressBar bar;

private Handler progressBarHandler = new Handler();

GradientDrawable progressGradientDrawable = new GradientDrawable(
        GradientDrawable.Orientation.LEFT_RIGHT, new int[]{
                0xff1e90ff,0xff006ab6,0xff367ba8});
ClipDrawable progressClipDrawable = new ClipDrawable(
        progressGradientDrawable, Gravity.LEFT, ClipDrawable.HORIZONTAL);
Drawable[] progressDrawables = {
        new ColorDrawable(0xffffffff),
        progressClipDrawable, progressClipDrawable};
LayerDrawable progressLayerDrawable = new LayerDrawable(progressDrawables);


int status = 0;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // TODO Auto-generated method stub
    setContentView(R.layout.startup);

    bar = (ProgressBar) findViewById(R.id.start_page_progressBar);
    bar.setProgress(0);
    bar.setMax(100);

    progressLayerDrawable.setId(0, android.R.id.background);
    progressLayerDrawable.setId(1, android.R.id.secondaryProgress);
    progressLayerDrawable.setId(2, android.R.id.progress);

    bar.setProgressDrawable(progressLayerDrawable);
}

这帮助我通过代码设置自定义颜色为progressbar。希望能有所帮助

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。

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。

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:)
