Layout to design Scientific calculator in Android.
Step-1:- While creating my project I am using empty activity.You can use any activity according to your requirement.
All written content of my project I use string.xml file.I also give string.xml file for scientific calculator.
string.xml
Step-2:- In your activity_main.xml paste the code mention below.This activity_main.xml work for portrait mode for mobile.
string.xml

button.xml

I am using three button of different color thats why to give click effect or change color onclick i am using 3 xml file like button.xml,button1.xml and button3.xml.You can give these xml name of your own choice.
To add this in your button go to drawable →(right click ) new→select vector asset double click on android icon button search desired icon from list and press Ok.Then press next and then finish.A new component add in drawable.Now you can add this icon to desired place using syntax android:src="@drawable/" .In inverted comas use name of component newly added from adding icon.In my project i am using this.You can watch my code.
Step-5:- Its time to change orientation from portrait to landscape.For this we need to create new activity_main.xml.In res go to layout (right click) layout drawable click on that.Apop box open in this box type infront of file name type activity_main.xml.Name should same as default xml file of project.Infront of directory name after layout use(-land) and combination of both look like (layout-land) to create landscape orientation.Inside this file type or paste the below code.
