默认值(不确定)

add

android:indeterminateTint="@color/white"

为确定

    android:progressTint="@color/color_1"

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

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>

android:progressTint="#ffffff" 

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

使用android.support.v4.graphics.drawable.DrawableCompat:

            Drawable progressDrawable = progressBar.getIndeterminateDrawable();
            if (progressDrawable  != null) {
                Drawable mutateDrawable = progressDrawable.mutate();
                DrawableCompat.setTint(mutateDrawable, primaryColor);
                progressBar.setProgressDrawable(mutateDrawable);
            }

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);
}
