I want to create Gridview similar to WPF datagrid i don't know how many of you know about WPF data grid i'll explain its like having header row and rows to bind and whenever i click on each column of header row, the column 'll be sorted. But in this android list view i didn't see any header like in WPF but sorting is there and it'll sorted irrespective of column i.e. when i click on first column at row position '0' all columns 'll be sorted including header row (means header row going downwards) so how can i slove my problem?
Thanks,

So you just want a header row in your listview? Call listView.addHeaderView() passing it the view/layout you want in the header.

A table has 3 columns. and rows keep on increasing dynamically. I want to display the 1 row data in 1 textview.
So If there are 5 rows, I want to dynamically create 5 textviews and insert data into them.
What is the logic for dynamically creating textviews based on upon the row count?
in these cases you better use listview or recyclerView. you need to make an adapter for them to populate each row's view and data of the view.
this way the data would be shown dynamically. you can see the instruction to use listview in below:

i have this table with dynamical table-row adding.
What I would like to do is not load the whole table because it sometimes has more than 10.000 rows.
I want to make a dynamically load the table is that possible?
For such thing, you must use ListView instead of TableLayout. Because with ListView, you can implement onScrollListener, with which you can load more iteam as and when required.
list view does have on scroll listener that will listen if you change focus of list view and you use simple logic to find when list view end is reached and respond accordingly
I'm trying to implement an irregular gridview for my Android app. I've defined the gridview to show 2 columns but I need to show just 1 column at the first row. Is it possible using a DataAdapter?
I don't think you can accomplish this with a gridview. The adapter simple provides the data, but the view decides how to lay it out. If your requirements allow you to make the number of columns constant, then maybe you can use the gridlayout instead. I'm thinking you could try to do you layout like the google currents app.
Gridview and ListView are super useful if you have 1000's of items since it reuses views as it scrolls. If you have lots a items in your grid, then I would probably try to use the GridView or ListView to accomplish your goal. Maybe you have to get your requirement changed. Another option is to use a ListView, but sub-divide each row into 2 columns.
I want the content of my gridview seperated with headers!
We can easily accomplish this in listview!
How to do this part in a gridview?
I want the same , as the headers has to be same and the cntent of each header must be a gridview of items! Please dont see and compare the content in the image below. its just a downloaded one!
Any help?
A GridView does not have columns. It is meant to arrange a flat (without columns) array of items two-dimensionally across the screen. You should use a TableLayout, which is intented to lay out columned rows.
When you use a TableLayout, you can add a header row as your first row and then add your data rows after that. There isn't a distinction between the two.
After reading Dynamically add elements to a listView Android , I understand clearly how to dynamically add row elements to a listView.
However, I have one idea that how to dynamically add column elements to a listview.
For example, there are 2 columns originally. After I click a button, I would like to add one one more column.
Can anyone provide example code?
Thank for all sharing.
Just add rows dynamically, but make a custom view with two different elements... So there'll be two elements on your every view of row. And first, set first items while seconds are invisible and after clicking button set others... So it'll seem that you're adding column...
