How to make a round button?

Question

I'm trying to make a round button, but I don't know how can I do it. I can make button with rounded corners, but how can I can round circle. It's not the same. Please, tell me, is it possible on Android? Thank you.

Answer 1

Create an xml file named roundedbutton.xml in drawable folder

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" 
android:shape="rectangle">
    <solid android:color="#eeffffff" />
    <corners android:bottomRightRadius="8dp"
        android:bottomLeftRadius="8dp"  
        android:topRightRadius="8dp"
        android:topLeftRadius="8dp"/>
</shape>

Finally set that as background to your Button as android:background = "@drawable/roundedbutton"

If you want to make it completely rounded, alter the radius and settle for something that is ok for you.

Answer 2

If using Android Studio you can just use:

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

    </shape>

this works fine for me, hope this helps someone.

1. Create a drawable/button_states.xml file containing:

   <?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="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>
       </item>
       <item android:state_pressed="true"> 
           <shape android:shape="rectangle">
           <corners android:radius="1000dp" />
           <solid android:color="#3AA76D" />
           <stroke
               android:width="2dip"
               android:color="#03ae3c" />
           <padding
               android:bottom="4dp"
               android:left="4dp"
               android:right="4dp"
               android:top="4dp" />
           </shape>
       </item>
   </selector>
   

2. Use it in button tag in any layout file

   <Button
       android:layout_width="220dp"
       android:layout_height="220dp"
       android:background="@drawable/button_states"
       android:text="@string/btn_scan_qr"
       android:id="@+id/btn_scan_qr"
       android:textSize="15dp"
   />
   

Answer 4

Markushi's android circlebutton:

(This library is deprecated and no new development is taking place. Consider using a FAB instead.)

Answer 5

If you want a FAB looking circular button and you are using the official Material Component library you can easily do it like this:

<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:

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

Answer 6

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

Set that on your XML drawable resources, and simple use and image button with an round image, using your drawable as background.

Answer 7

<corners android:bottomRightRadius="180dip"
    android:bottomLeftRadius="180dip"
    android:topRightRadius="180dip"
    android:topLeftRadius="180dip"/>

<solid android:color="#6E6E6E"/> <!-- this one is ths color of the Rounded Button -->

and add this to the button code

    android:layout_width="50dp"
    android:layout_height="50dp"

Answer 8

Used the shape as oval. This makes the button oval

<item>
    <shape android:shape="oval" >
        <stroke
            android:height="1.0dip"
            android:width="1.0dip"
            android:color="#ffee82ee" />

        <solid android:color="#ffee82ee" />

        <corners
            android:bottomLeftRadius="12.0dip"
            android:bottomRightRadius="12.0dip"
            android:radius="12.0dip"
            android:topLeftRadius="12.0dip"
            android:topRightRadius="12.0dip" />
    </shape>
</item>

Answer 9

You can use a MaterialButton:

     <com.google.android.material.button.MaterialButton
            android:layout_width="48dp"
            android:layout_height="48dp"
            android:insetTop="0dp"
            android:insetBottom="0dp"
            android:text="A"
            app:shapeAppearanceOverlay="@style/ShapeAppearanceOverlay.App.Rounded"
            />

and apply a circular ShapeAppearanceOverlay with:

<style name="ShapeAppearanceOverlay.App.rounded" parent="">
    <item name="cornerSize">50%</item>
</style>

    android:color="#FFFFFF" />

<solid android:color="#ffee82ee" />


<corners
    android:bottomLeftRadius="45dp"

Answer 13

Yes it's possible, look for 9-patch on google. Good articles :

Answer 14

Update 2021:

Just use the MaterialButton

<com.google.android.material.button.MaterialButton
    app:cornerRadius="30dp"
    android:layout_width="60dp"
    android:layout_height="60dp"
    android:text="test" />

• width equal height
• cornerRadius is half of the width or height

Answer 15

You can use google's FloatingActionButton

XMl:

<android.support.design.widget.FloatingActionButton
    android:id="@+id/fab"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@android:drawable/ic_dialog_email" />

Java:

  @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    FloatingActionButton bold = (FloatingActionButton) findViewById(R.id.fab);
    bold.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
        // Do Stuff
        }
    });
}

Gradle:

    compile 'com.android.support:design:23.4.0'

Answer 16

I simply use a FloatingActionButton with elevation = 0dp to remove the shadow:

<com.google.android.material.floatingactionbutton.FloatingActionButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/ic_send"
    app:elevation="0dp" />

Answer 17

I like this solution

            <androidx.cardview.widget.CardView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                app:cardCornerRadius="18dp"
                app:cardElevation="0dp"
                >
                <ImageButton
                        android:layout_width="35dp"
                        android:layout_height="35dp"
                        android:background="@null"
                       android:scaleType="centerCrop"
              android:src="@drawable/social_facebook"
                        />
            </androidx.cardview.widget.CardView>
