您可以使用以下代码在运行时更改进度条颜色：

final ProgressBar progressBar = findViewById(R.id.pb);
Drawable progressDrawable = progressBar.getIndeterminateDrawable();

if (progressDrawable != null && progressBar.getProgress() < 90) {
    final Drawable mutateDrawable = progressDrawable.mutate();
    DrawableCompat.setTint(mutateDrawable, Color.RED);
    progressBar.setProgressDrawable(mutateDrawable);
} else {
    final Drawable mutateDrawable = progressDrawable.mutate();
    DrawableCompat.setTint(mutateDrawable, Color.GREEN);
    progressBar.setProgressDrawable(mutateDrawable);
}
