Acctuly in this code I had given my xml code instead of html and java instead of CSS 😂
so please cheque it. when I comment out my grdvw (line 18 in html) section then the installed app runs perfectly but if grdvw is uncommented it installs the app but dose not allowe to run it .
Acctuly I want to make a calculator android app.
So I need a grid so that all elements and buttons can be packed easily .
Help me out to sove this error

Answer 1

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

Answer 9

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 🥰
