How to use RippleDrawable programmatically in code (not xml) with Android 5.0 Lollipop?

This is how I was able to achieve this.

Note that this is Api 21+ only so you will have to fallback to a normal Drawable if you support lower versions.

public static RippleDrawable getPressedColorRippleDrawable(int normalColor, int pressedColor){    return new RippleDrawable(getPressedColorSelector(normalColor, pressedColor), getColorDrawableFromColor(normalColor), null);}public static ColorStateList getPressedColorSelector(int normalColor, int pressedColor){    return new ColorStateList(        new int[][]            {                new int[]{android.R.attr.state_pressed},                new int[]{android.R.attr.state_focused},                new int[]{android.R.attr.state_activated},                new int[]{}            },        new int[]            {                pressedColor,                pressedColor,                pressedColor,                normalColor            }    );}public static ColorDrawable getColorDrawableFromColor(int color){    return new ColorDrawable(color);}

Edit:I tinkered with this some more and discovered that the ColorStateList doesn't need to be nearly as complex as the above solution. I have simplified it to the below snippet. (Everything else in the above code block is the same. I only changed the ColorStateList creation.) I will leave the above block as the original, in case this method doesn't work for someone.

new ColorStateList(    new int[][]        {            new int[]{}        },    new int[]        {            pressedColor        });

public static Drawable getAdaptiveRippleDrawable(    int normalColor, int pressedColor) {    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {        return new RippleDrawable(ColorStateList.valueOf(pressedColor),                null, getRippleMask(normalColor));    } else {        return getStateListDrawable(normalColor, pressedColor);    }}private static Drawable getRippleMask(int color) {    float[] outerRadii = new float[8];    // 3 is radius of final ripple,     // instead of 3 you can give required final radius    Arrays.fill(outerRadii, 3);    RoundRectShape r = new RoundRectShape(outerRadii, null, null);    ShapeDrawable shapeDrawable = new ShapeDrawable(r);    shapeDrawable.getPaint().setColor(color);    return shapeDrawable;}public static StateListDrawable getStateListDrawable(    int normalColor, int pressedColor) {    StateListDrawable states = new StateListDrawable();    states.addState(new int[]{android.R.attr.state_pressed},         new ColorDrawable(pressedColor));    states.addState(new int[]{android.R.attr.state_focused},         new ColorDrawable(pressedColor));    states.addState(new int[]{android.R.attr.state_activated},         new ColorDrawable(pressedColor));    states.addState(new int[]{},         new ColorDrawable(normalColor));    return states;}

You can get the drawable and apply to any view using view.setDrawable.
For Lollipop+ devices you will get ripple else it will change the color of view.

Basically, you need to create a new RippleDrawable object. For pre-Lollipop devices, you want a StateListDrawable (as others already suggested). I've written a somewhat resourceful GIST with a bunch of useful methods related to Drawables and coloring:https://gist.github.com/milosmns/6566ca9e3b756d922aa5

Most likely you will want to use #getBackgroundDrawable() from that singleton.
