Here is a point to note that  GridView gets its data from a ListAdapter, the only data loaded in memory will be the one displayed on screen.  Whereas a GridLayout is a layout that places its children in a rectangular grid. So that's why i used GridLayout here instead of GridView So don't be confused https://code.sololearn.com/WiKu1W1SIce4/?ref=app i have added few buttons only, you can change it according to your requirement


I guess Grdvw should be GridView in android


They have GridView Search it out

丹ⓨㄩک廾 🇮🇳 yeah i will show you🙂👍


Now if you have any doubt regarding this you can feel free to ask me🙂🙂👍


I dont think so Lamya😉 ["非活性"] because xml dosent have predefined tags


Aakaanksha 💕 ...she can only tell...or Raj Srivastava Lamya😉 ["非活性"]


May be Lamya😉 ["非活性"] but I need to modify that code so that I can use 4×6 grids for the calculator buttons . Do you know how can I do that because GridView will not provide that feature. I want all the button widgets in xml itself


Ok thanks Lamya😉 ["非活性"] . Just edit the xml if you can 🥰


We often give them a name for our convenience but thay are not reserved words . For example we often write Main as a class name in for main class. ok let me try Lamya😉 ["非活性"]


丹ⓨㄩک廾 🇮🇳 ...if any problem in Java Beyond arrays...then u can ask Lamya Sis...she is one of the best in this.. But under Arrays strings and operators..I can tell..that's all


Lamya😉 ["非活性"] can u please help me in my html codes and some Java..please lamy....🙏🙏
