There is some inherit problem with the borders of the button. But I found the best way to do it. Let say if you want a border only on the left side of the button. In the MainActivity xml file where the button is placed do it like this -
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@drawable/newstyle"
android:orientation="vertical" >
<Button
android:id="@+id/button3"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@null"
android:gravity="center_vertical"
android:paddingLeft="10sp"
android:text="Button"
android:textAllCaps="false"
android:textColor="#939393"
android:textSize="20sp" />
</LinearLayout>
For the newstyle.xml file which will be located in the drawable use this code -
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:bottom="0sp"
android:left="-2sp"
android:right="-2sp"
android:top="-2sp">
<shape android:shape="rectangle" >
<solid android:color="#ffffff" />
<stroke
android:width="1sp"
android:color="#d6d6d6" />
</shape>
</item>
</layer-list>
So the whole idea is -
Keep the background of the button as @null and keep the button in the linera layout. Give the background to the liner layout and voila its done..:)..
