Thank you so much 😀
Sir I became fan of your teaching.
thank you sir,i just try this program it's successfully run...your explanation is very good and simple anyone can understandable....
Thanks keep watching and sharing with friends
Dear sir your explanation is very clear and appreciated.
I have some requirement to fill in. That the number input should be from right and should have decimal. For example, when click '4','7' and '8'. The panel have to show value 4¢, 47¢ and then RM4 and 78¢. Hence, I have tried the option Number (Decimal) from Text palette instead of Plain Text. However, the decimal is not showing in the display sir. Moreover, we could not permit to design Dot button as well sir. Is there any method for it sir? Kindly please provide assistance sir. Thanks in advance.
How to select the buttons sir??

I rechecked the code sir....my app closes when equal pressed....pls help
Very nice video Sir👍 , but there is a small change you have to make , you have to use else if statements instead of if, otherwise only division operation will be performed when you click on any button.
This is for you understanding ....now you can improve it...
bahut badhiya sir....ek ek cheez bahut achhe se explain kiya aapne..!(last k 6 - 7 second mein badhiya rap kiya 😍😂)

Use if else in sub div and multiply choices instead of if if if if for each nahi to application equal k button k click pr bnd ho jati hy

Sir, maine ye app banaya aur jab iska apk install kiya toh sab properly work kar rha tha lekin jab mai ÷, ×, =, -, + click karta hu bina koi no. Type kiye toh app crash ho jata h. Please help karea.isko thik karne ke liye code bataea eik video banake. Sabko yahi problem h
use *try* and *catch* error method it prevents your app to crash
Good
Lekin is may ik problem hai.
Agr ap ik number per click karty awr per add button pe click krtu hai pir dusry number ke bajayi equal pe click krty hai ap ka app band hujata hai
This is just one simple app... improve according to your requirements

I want to get the output without pressing equals button.The default calculator app provided by android OS provides this feature. i mean it show output 2+2 directly 4 without pressing equals button
event handle karna hoga....

Same here
Please check code again
I don't want my history to clear, I want it to be like a real calculator where until and unless I complete the task I'll see all the values entered. For this how should I manipulate. Example if I want to add 1+2, I want this two value to stay there and go away only when their Ans is to be displayed
