Answer 1

try Material button

Set app:strokeWidth, app:strokeColor as per your need

<com.google.android.material.button.MaterialButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    style="@style/Widget.MaterialComponents.Button.OutlinedButton"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:strokeWidth="0.6dp"
    app:cornerRadius="2dp"
    android:text="Reassign"
    android:textColor="@color/colorAccent"
    app:strokeColor="@color/colorAccent"

    />

Note : you need to add dependency for material widgets

//Material Components for Android
implementation 'com.google.android.material:material:1.0.0'

Answer 2

Use the <stroke> element. Add this xml file in res/drawable folder as button_border.xml:

 <?xml version="1.0" encoding="utf-8"?>
  <shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <gradient android:startColor="#FFFFFF" 
       android:endColor="#00FF00"
       android:angle="270" />
    <corners android:radius="3dp" />
    <stroke android:width="5px" android:color="#ffffff" />
 </shape>

then call this by

<Button
   android:id="@+id/button1"
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:layout_margin="10dp"
   android:background="@drawable/button_border"
   android:text="Button" 
/>

Try this

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

<corners android:radius="1dp" />

<stroke
    android:width="2px"
    android:color="#ffffff" />

</shape>

Answer 4

If you would like a transparent background for your button, then use Shivang Trivedi's answer but remove the "gradient" section like so:

<?xml version="1.0" encoding="utf-8"?>   <shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <corners android:radius="3dp" />
    <stroke android:width="5px" android:color="#ffffff" />  </shape>

    android:endColor="#E8f2fe"
