Change progressbar color through CODE ONLY in Android

This will help much no need to do so much coding :)

ProgressBar spinner = new android.widget.ProgressBar(
            context,
            null,
            android.R.attr.progressBarStyle);

spinner.getIndeterminateDrawable().setColorFilter(0xFFFF0000,android.graphics.PorterDuff.Mode.MULTIPLY);

In the case that you need to tint the background and the progress bar in different colors.

progress_drawable.xml

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@android:id/background">
        <shape android:shape="rectangle" >
            <solid android:color="@color/white" />
        </shape>
    </item>
    <item android:id="@android:id/progress">
        <clip>
            <shape>
                <solid android:color="@color/green" />
            </shape>
        </clip>
    </item>
</layer-list>

Its possible, programmatically, to decompound its layer-list items, and tint them separately:

LayerDrawable progressBarDrawable = (LayerDrawable) progressBar.getProgressDrawable();
Drawable backgroundDrawable = progressBarDrawable.getDrawable(0);
Drawable progressDrawable = progressBarDrawable.getDrawable(1);

backgroundDrawable.setColorFilter(ContextCompat.getColor(this.getContext(), R.color.white), PorterDuff.Mode.SRC_IN);
progressDrawable.setColorFilter(ContextCompat.getColor(this.getContext(), R.color.red), PorterDuff.Mode.SRC_IN);

Update

In newer versions of Android (21 works), you can change the color of a progressbar programmatically by just using setProgressTintList.

To set it red, use:

//bar is a ProgressBar
bar.setProgressTintList(ColorStateList.valueOf(Color.RED));
