change the appearance of button into round button

Issue

I want to made the present rectangular button into round shape and add the picture of share button in it. I mean the button should be of round share and it should have only image(fit) of "share"

<Button
        android:id="@+id/button3"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginEnd="10dp"
        android:layout_marginTop="8dp"
        android:text="03"
        android:textStyle="bold"/>

Solution

Create drawable file as bg_share.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">

<solid
    android:color="@color/colorPrimaryDark">
</solid>

<corners
    android:radius="500dp">
</corners>

<padding
    android:top="0dp"
    android:right="10dp"
    android:left="10dp"
    android:bottom="0dp">
</padding>

</shape>

And in your main.xml create imageview instead of button like

 <ImageView
       android:id="@+id/share"                         
       android:layout_width="wrap_content"                        
       android:layout_height="wrap_content"                        
       android:background="@drawable/bcshare"
       android:padding="10dp"
       android:src="@drawable/ic_share_black_24dp" />

In MainActivity.java do something like this

 share.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
           //Your code...
        }
    });
