如果不确定的:

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

因为方法公共无效setColorFilter(@ColorInt int颜色，@NonNull PorterDuff。模式模式)已弃用，我使用这样的形式:

progressBar.indeterminateDrawable.colorFilter =
            PorterDuffColorFilter(ContextCompat.getColor(this, R.color.black), PorterDuff.Mode.SRC_IN)

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。

很抱歉，这不是答案，但是是什么驱使需求从代码中设置它呢? 如果定义正确。setprogressdrawable应该工作

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

<item android:id="@android:id/background">
    <shape>
        <corners android:radius="5dip" />
        <gradient
                android:startColor="#ff9d9e9d"
                android:centerColor="#ff5a5d5a"
                android:centerY="0.75"
                android:endColor="#ff747674"
                android:angle="270"
        />
    </shape>
</item>

<item android:id="@android:id/secondaryProgress">
    <clip>
        <shape>
            <corners android:radius="5dip" />
            <gradient
                    android:startColor="#80ffd300"
                    android:centerColor="#80ffb600"
                    android:centerY="0.75"
                    android:endColor="#a0ffcb00"
                    android:angle="270"
            />
        </shape>
    </clip>
</item>

<item android:id="@android:id/progress">
    <clip>
        <shape>
            <corners
                android:radius="5dip" />
            <gradient
                android:startColor="@color/progress_start"
                android:endColor="@color/progress_end"
                android:angle="270" 
            />
        </shape>
    </clip>
</item>

</layer-list>

这对我很有用。它也适用于低版本。将其添加到您的syles.xml中

<style name="ProgressBarTheme" parent="ThemeOverlay.AppCompat.Light">
<item name="colorAccent">@color/colorPrimary</item>
</style>

在xml中像这样使用它

<ProgressBar
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:theme="@style/ProgressBarTheme"
   />
