Below is the AppCompat way of changing both the track and thumb color programmatically, for a specific SwitchCompat. For this example, I have hardcoded the thumbColor to red. Ideally, you would set the color through a second method parameter.

Please note that when the switch is checked, a ripple is displayed. The ripple color will not be changed by the code below.

public static void setSwitchColor(SwitchCompat v) {
    // thumb color of your choice
    int thumbColor = Color.RED;

    // trackColor is the thumbColor with 30% transparency (77)
    int trackColor = Color.argb(77, Color.red(thumbColor), Color.green(thumbColor), Color.blue(thumbColor));

    // setting the thumb color
    DrawableCompat.setTintList(v.getThumbDrawable(), new ColorStateList(
            new int[][]{
                    new int[]{android.R.attr.state_checked},
                    new int[]{}
            },
            new int[]{
                    thumbColor,
                    Color.WHITE
            }));

    // setting the track color
    DrawableCompat.setTintList(v.getTrackDrawable(), new ColorStateList(
            new int[][]{
                    new int[]{android.R.attr.state_checked},
                    new int[]{}
            },
            new int[]{
                    trackColor,
                    Color.parseColor("#4D000000") // full black with 30% transparency (4D)
            }));
}
