android – How to make a round button?

Posted by: admin March 11, 2020 Leave a comment

Questions:

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.

How to&Answers:

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:

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="ring">
        <solid android:color="#FFFFFF"/>

    </shape>

this works fine for me, hope this helps someone.

Answer:

  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:

Markushi’s android circlebutton:

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

enter image description here

Answer:

<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:

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:

<?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>

Answer:

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

http://radleymarx.com/blog/simple-guide-to-9-patch/

http://ogrelab.ikratko.com/custom-color-buttons-for-android/

Answer:

It is

android.R.drawable.expander_ic_minimized

look into built in android drawables:

http://androiddrawableexplorer.appspot.com/

Answer:

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:

  1. Use the Image Buttons and make the background as the image you want.
  2. Create the images from the android asset studio link –

https://romannurik.github.io/AndroidAssetStudio/icons-launcher.html#foreground.type=image&foreground.space.trim=0&foreground.space.pad=0.25&foreColor=rgba(94%2C%20126%2C%20142%2C%200)&backColor=rgb(96%2C%20125%2C%20139)&crop=1&backgroundShape=circle&effects=none&name=ic_home

and download it, extraxt it , inside that look for mipmap-hdpi folder.

  1. copy the image from the mipmap-hdpi folder and paste it in the drwable folder of your android project.

  2. Now set the background as that image.

Answer:

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:

enter image description here

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