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));

As I found help on a topic here but can't remember the link, I'm posting my full solution which works great for my needs:

    // Draw a simple progressBar from xml
    progressBar = new ProgressBar(this, null, android.R.attr.progressBarStyleHorizontal);

    // Convert the color (Decimal value) to HEX value: (e.g: #4b96a0)
    String color = colorDecToHex(75, 150, 160);

    // Define a shape with rounded corners
    final float[] roundedCorners = new float[] { 5, 5, 5, 5, 5, 5, 5, 5 };
    ShapeDrawable pgDrawable = new ShapeDrawable(new RoundRectShape(roundedCorners,     null, null));

    // Sets the progressBar color
    pgDrawable.getPaint().setColor(Color.parseColor(color));

    // Adds the drawable to your progressBar
    ClipDrawable progress = new ClipDrawable(pgDrawable, Gravity.LEFT, ClipDrawable.HORIZONTAL);
    progressBar.setProgressDrawable(progress);

    // Sets a background to have the 3D effect
    progressBar.setBackgroundDrawable(Utils.getActivity().getResources()
            .getDrawable(android.R.drawable.progress_horizontal));

    // Adds your progressBar to your layout
    contentLayout.addView(progressBar);

And here is the code to convert DECIMAL color values to HEXADECIMAL:

public static String colorDecToHex(int p_red, int p_green, int p_blue)
{
    String red = Integer.toHexString(p_red);
    String green = Integer.toHexString(p_green);
    String blue = Integer.toHexString(p_blue);

    if (red.length() == 1)
    {
        red = "0" + red;
    }
    if (green.length() == 1)
    {
        green = "0" + green;
    }
    if (blue.length() == 1)
    {
        blue = "0" + blue;
    }

    String colorHex = "#" + red + green + blue;
    return colorHex;
}

I think the last method is not that clean but it works well.

Hope this well help, too much time wasted on this progressbar.
