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.
This question is related to
android
android-button
and download it, extraxt it , inside that look for mipmap-hdpi folder.
copy the image from the mipmap-hdpi folder and paste it in the drwable folder of your android project.
Now set the background as that image.
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.
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>
Markushi's android circlebutton:
(This library is deprecated and no new development is taking place. Consider using a FAB instead.)
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/
It is
android.R.drawable.expander_ic_minimized
look into built in android drawables:
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>
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"
/>
For a round button create a shape:
<?xml version="1.0" encoding="utf-8"?>
<stroke
android:width="8dp"
android:color="#FFFFFF" />
<solid android:color="#ffee82ee" />
<corners
android:bottomLeftRadius="45dp"
android:bottomRightRadius="45dp"
android:topLeftRadius="45dp"
android:topRightRadius="45dp" />
use it as a background of your button link
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'
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" />
<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"
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
.
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>
Fully rounded circle shape.
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#FFFFFF" />
<stroke
android:width="1dp"
android:color="#F0F0F0" />
<corners
android:radius="90dp"/>
</shape>
Happy Coding!
I went through all the answers. But none of them is beginner friendly. So here I have given a very detailed answers fully explained with pictures.
Open Android Studio. Go to Project Window and scroll to drawable folder under res folder
Right click, select New --> drawable resource folder
In the window that appears, name the file rounded_corners
and click on OK
A new file rounded_corners.xml
gets created
Open the file. You are presented with the following code -->
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://android.com/apk/res/android">
</selector>
Replace it with the following code -->
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<corners android:radius="8dp" />
<solid android:color="#66b3ff" />
</shape>
Here the design view can be seen on the right side
Adjust the value in android:radius
to make the button more or less rounded.
Then go to activity_main.xml
Put the following code -->
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity"
android:padding="10dp">
<Button
android:id="@+id/_1"
android:text="1"
android:textSize="25dp"
android:textColor="#ffffff"
android:background="@drawable/rounded_corners"
android:layout_width="50dp"
android:layout_height="wrap_content"
android:layout_margin="20dp"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"/>
</RelativeLayout>
Here I have placed the Button
inside a RelativeLayout
. You can use any Layout
you want.
For reference purpose MainActivity.java
code is as follows -->
import android.app.Activity;
import android.os.Bundle;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
I have a Pixel 4 API 30 avd installed. After running the code in the avd the display is as follows -->
<?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.
You can make a ImageButton
with circular background image.
use ImageButton instead of Button....
and make Round image with transparent background
