This example demonstrates how to get the Custom circle button in android.
Method 1: Use XML drawable like this:
Save the following contents as round_button.xml
in drawable
folder.
Note: you just need to save it to the ‘drawable’ folder, any XML resource for drawable is typically saved in ‘drawable’, not in mdpi, hdpi, etc.
<?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 the 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 the 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:
- If you want it to show all these states (enabled, disabled, highlighted, etc), you will use the selector as described here.
- You’ve to keep both files in order to make the drawable backward-compatible. Otherwise, you’ll face weird exceptions in the previous android version.

Method 2: 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>
Method 3: Using Vactor Asset
Create a new vector asset in the drawable folder.
You can import your PNG image as well, and convert the file to SVG online at https://image.online-convert.com/convert-to-svg. The higher the resolution, the better the conversion will be.
Next, create a new vector asset from that SVG file.
This is a sample vector circle image you can use. Copy the code to an XML file in the drawables folder.
ic_check.xml:
<vector xmlns:android="http://schemas.android.com/apk/res/android"
android:width="24dp"
android:height="24dp"
android:viewportHeight="256"
android:viewportWidth="256">
<path
android:fillColor="#2962FF"
android:pathData="M111,1.7c-7.2,1.1 -22.2,4.8 -27.9,7 -33.2,12.5 -61.3,40.3 -74.1,73.3 -8.7,22.6 -10.5,55.3 -4.4,78 10.9,40 39.7,72.4 77.4,87 22.6,8.7 55.3,10.5 78,4.4 45.3,-12.3 79.1,-46.1 91.4,-91.4 2.9,-10.7 3.9,-21.9 3.3,-37.4 -0.7,-21.2 -4.6,-35.9 -14,-54.1 -18.2,-35 -54,-60.5 -93.4,-66.4 -6.7,-1 -30.7,-1.3 -36.3,-0.4zM145,23.1c21.8,3.3 46.5,16.5 61.1,32.8 20.4,22.6 30.1,51.2 27.7,81.1 -3.5,44.4 -35.9,82.7 -79.6,94 -21.6,5.6 -46.6,3.7 -67.8,-5.1 -10.4,-4.3 -24.7,-14.1 -33.4,-22.9 -41.6,-41.5 -41.6,-108.4 0,-150 24.3,-24.3 57.6,-35.1 92,-29.9z"
android:strokeColor="#00000000" />
<path
android:fillColor="#2962FF"
android:pathData="M148.4,113c-24.6,26 -43.3,44.9 -44,44.6 -0.7,-0.3 -8.5,-6.1 -17.3,-13 -8.9,-6.9 -16.5,-12.6 -17,-12.6 -1.4,-0 -25.6,19 -25.8,20.3 -0.3,1.4 62.7,50.2 64.8,50.2 1.7,-0 108.4,-112.3 108.4,-114.1 0,-1.3 -23.8,-20.4 -25.4,-20.4 -0.6,-0 -20.2,20.3 -43.7,45z"
android:strokeColor="#00000000" />
</vector>
Use this image in your button:
<ImageButton
android:id="@+id/btn_level1"
android:layout_width="36dp"
android:layout_height="36dp"
android:background="@drawable/ic_check"
/>
Your button will be a circle button.
Method 4: Using Material Components library Official Library
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:
With jetpack compose you can use:
Button(
onClick = { /* Do something! */ },
modifier = Modifier.width(48.dp).height(48.dp),
shape = CircleShape
) {
Icon(Icons.Filled.Add, "")
}
