How to&Answers:

Use xml drawable like this:

Save the following contents as round_button.xml in drawable folder

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="false">
        <shape android:shape="oval">
            <solid android:color="#fa09ad"/>
        </shape>
    </item>
    <item android:state_pressed="true">
        <shape android:shape="oval">
            <solid android:color="#c20586"/>
        </shape>
    </item>
</selector>

Android Material Effect: Although FloatingActionButton is a better option, If you want to do it using xml selector, create a folder drawable-v21 in res and save another round_button.xml there with following xml

<?xml version="1.0" encoding="utf-8"?>
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
    android:color="#c20586">
    <item>
        <shape android:shape="oval">
            <solid android:color="#fa09ad"/>
        </shape>
    </item>
</ripple>

And set it as background of Button in xml like this:

<Button
android:layout_width="50dp"
android:layout_height="50dp"
android:background="@drawable/round_button"
android:gravity="center_vertical|center_horizontal"
android:text="hello"
android:textColor="#fff" />

Important:

  1. If you want it to show all these states (enabled, disabled, highlighted etc), you will use selector as described here.
  2. You’ve to keep both files in order to make the drawable backward-compatible. Otherwise, you’ll face weird exceptions in previous android version.

Answer:

With the official Material Components library you can use the MaterialButton applying a Widget.MaterialComponents.Button.Icon style.

Something like:

   <com.google.android.material.button.MaterialButton
            android:layout_width="48dp"
            android:layout_height="48dp"
            style="@style/Widget.MaterialComponents.Button.Icon"
            app:icon="@drawable/ic_add"
            app:iconSize="24dp"
            app:iconPadding="0dp"
            android:insetLeft="0dp"
            android:insetTop="0dp"
            android:insetRight="0dp"
            android:insetBottom="0dp"
            app:shapeAppearanceOverlay="@style/ShapeAppearanceOverlay.MyApp.Button.Rounded"
            />

Currently the app:iconPadding="0dp",android:insetLeft,android:insetTop,android:insetRight,android:insetBottom attributes are needed to center the icon on the button avoiding extra padding space.

Use the app:shapeAppearanceOverlay attribute to get rounded corners. In this case you will have a circle.

  <style name="ShapeAppearanceOverlay.MyApp.Button.Rounded" parent="">
    <item name="cornerFamily">rounded</item>
    <item name="cornerSize">50%</item>
  </style>

The final result:

Answer:

if you want use VectorDrawable and ConstraintLayout

<FrameLayout
            android:id="@+id/ok_button"
            android:layout_width="100dp"
            android:layout_height="100dp"
            android:foreground="?attr/selectableItemBackgroundBorderless"
            android:background="@drawable/circle_button">
                <android.support.constraint.ConstraintLayout
                    android:layout_width="match_parent"
                    android:layout_height="match_parent">
                    <ImageView
                        android:id="@+id/icon_of_button"
                        android:layout_width="32dp"
                        android:layout_height="32dp"
                        app:layout_constraintBottom_toBottomOf="parent"
                        app:layout_constraintTop_toTopOf="parent"
                        app:layout_constraintRight_toRightOf="parent"
                        app:layout_constraintLeft_toLeftOf="parent"
                        app:srcCompat="@drawable/ic_thumbs_up"/>
                    <TextView
                        android:id="@+id/text_of_button"
                        android:layout_width="wrap_content"
                        android:layout_height="wrap_content"
                        app:layout_constraintTop_toBottomOf="@+id/icon_of_button"
                        app:layout_constraintRight_toRightOf="parent"
                        app:layout_constraintLeft_toLeftOf="parent"
                        android:layout_marginTop="5dp"
                        android:textColor="@android:color/white"
                        android:text="ok"
                        />
                </android.support.constraint.ConstraintLayout>
            </FrameLayout>

circle background: circle_button.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners android:radius="1000dp" />
<solid android:color="#41ba7a" />
<stroke
    android:width="2dip"
    android:color="#03ae3c" />
<padding
    android:bottom="4dp"
    android:left="4dp"
    android:right="4dp"
    android:top="4dp" />
</shape>

Answer:

For a FAB looking button this style on a MaterialButton:

<com.google.android.material.button.MaterialButton
    style="@style/Widget.MaterialComponents.ExtendedFloatingActionButton"
    app:cornerRadius="28dp"
    android:layout_width="56dp"
    android:layout_height="56dp"
    android:text="1" />

Result:

enter image description here

If you change the size be careful to use half of the button size as app:cornerRadius.
