Android L's Ripple Effect - Touch Feedback for Buttons - Using XML

UPDATE Material Components:

With the Material Components Library it is very easy to apply a ripple.

Just use the MaterialButton and the app:rippleColor attribute:

<com.google.android.material.button.MaterialButton
    app:rippleColor="@color/my_selector"
    ../>

With a selector like this:

<selector xmlns:android="http://schemas.android.com/apk/res/android">

  <item android:alpha="..." android:color="?attr/colorOnPrimary" android:state_pressed="true"/>
  <item android:alpha="..." android:color="?attr/colorOnPrimary" android:state_focused="true" android:state_hovered="true"/>
  <item android:alpha="..." android:color="?attr/colorOnPrimary" android:state_focused="true"/>
  <item android:alpha="..." android:color="?attr/colorOnPrimary" android:state_hovered="true"/>
  <item android:alpha="..." android:color="?attr/colorOnPrimary"/>

</selector>

Old answer

You can do something like this:

<Button
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:background="@drawable/ripple"
      
    />

Where the ripple.xml is:

<ripple xmlns:android="http://schemas.android.com/apk/res/android" 
                      android:color="?android:colorControlHighlight">
        <item android:id="@android:id/mask">
            <shape android:shape="oval">
                <solid android:color="?android:colorAccent" />
            </shape>
        </item>
 </ripple>

Add ripple effect to my button with button background color?

Here is another drawable xml for those who want to add all together gradient background, corner radius and ripple effect:

<?xml version="1.0" encoding="utf-8"?>
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
    android:color="@color/colorPrimaryDark">
    <item android:id="@android:id/mask">
        <shape android:shape="rectangle">
            <solid android:color="@color/colorPrimaryDark" />
            <corners android:radius="@dimen/button_radius_large" />
        </shape>
    </item>

    <item android:id="@android:id/background">
        <shape android:shape="rectangle">
            <gradient
                android:angle="90"
                android:endColor="@color/colorPrimaryLight"
                android:startColor="@color/colorPrimary"
                android:type="linear" />
            <corners android:radius="@dimen/button_radius_large" />
        </shape>
    </item>
</ripple>

Add this to the background of your button.

<Button
    ...
    android:background="@drawable/button_background" />

PS: this answer works for android api 21 and above.

Get ripple effect on transparent custom button view

You should use a RippleDrawable as the background of your custom button. The RippleDrawable has a mask layer, which is what you are looking for. To do this programmatically, you can create a RippleDrawable like so:

float[] outerRadii = new float[8];
Arrays.fill(outerRadii, height / 2);

RoundRectShape shape = new RoundRectShape(outerRadii, null, null);
ShapeDrawable mask = new ShapeDrawable(shape);

ColorStateList stateList = ColorStateList.valueof(ContextCompat.getColor(getContext(), R.color.ripple));

setBackground(new RippleDrawable(stateList, getBackgroundDrawable(), mask);

Keep in mind that RippleDrawable is only available for API Level 21+, so if you are looking to support older versions as well you will need to fall back to something else; possibly android.R.attr.selectableItemBackground or a StateListDrawable, which will give your button a basic "pressed" background for older platform versions.

Using android:itemBackground with a ripple effect

You could try to set actionOverflowMenuStyle like below :

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
  <item name="colorPrimary">@color/colorPrimary</item>
  <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
  <item name="colorAccent">@color/colorAccent</item>
  <item name="actionOverflowMenuStyle">@style/CMOptionsMenu</item>
</style>

<style name="CMOptionsMenu" parent="Widget.AppCompat.PopupMenu.Overflow">
   <item name="android:popupBackground">@color/colorItemBg</item>
</style>

Android L ripple touch effect on shape?

Try that one:

ripple.xml

<?xml version="1.0" encoding="utf-8"?>
<ripple android:color="@color/COLOR_WHILE_PRESSING" xmlns:android="http://schemas.android.com/apk/res/android">
 <item android:drawable="@drawable/background"></item>
</ripple>

background.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
 <solid android:color="@color/BACKGROUND_COLOR" />
 <corners android:radius="6dp" />
</shape>

Can't see click ripple effect in Android Touch events

I found a way around this. Although the ripple effect is not customisable, the fix is pretty nifty. I manually called the setPressed() method on View inside the ACTION_DOWN and ACTION_UP events and now I can see the default Android ripple effect.

case MotionEvent.ACTION_DOWN:
                        //icon.setColorFilter(Color.argb(80, 0, 0, 0));
                        v.setPressed(true);
                        if(mAppActionDownListener != null) {
                            mAppActionDownListener.onAppActionDown(appObjectList.get(position), v);
                        }
                        Log.d("COOK", "ACTION_DOWN: " + ev.getX() + ", " + ev.getY());
                        t1 = System.currentTimeMillis();
                        return true;

                    case MotionEvent.ACTION_UP:
                        v.setPressed(false);
                        Log.d("COOK", "ACTION_UP: " + ev.getX() + ", " + ev.getY());
                        t2 = System.currentTimeMillis();
                        if(Math.abs(t2-t1) <=300) {
                            //Toast.makeText(context, "Click event", Toast.LENGTH_SHORT).show();
                            if(mAppClickListener!=null) {
                                mAppClickListener.onAppClicked(appObjectList.get(position), v);
                            }
                        }
