Tablelayout与海量数据android

Question

What is the best way to create a table layout or recyclerview/listview/gridview in android that can pull a lot of data around 1000 rows and around 50 columns each row without to crash ?

I want to show it like excel sheet nothing special just show data of course with scrolling both ways.

Answer 1

TableFixHeaders project on github has an implementation with both Adapter an Recycling of views, plus handles scrolling wery nicely. And is quite easy to modify to suit your needs.

This is not so uncommon request, so it has been done numerous times. I am sure you can find other implementations if this one is not right for you.

Answer 2

I saw a similar question on SO a few months ago, and I was interested to see if I could develop a solution.

My concept was to start with a ListView for vertical scrolling and view recycling. Each list item is a HorizontalScrollView to show a table row with many columns. The trick here is to listen to each HorizontalScrollView for swipe events and then scroll every HorizontalScrollView in sync with the view being swiped.

I have a proof-of-concept project on Github here: klarson2/android-table-test

Downsides: The project was set up for Eclipse, so you can't open it directly with Android Studio. There is still a small bug with event handling that I haven't got around to fixing. Another limitation is that each cell view in the horizontal LinearLayout must be a fixed size so that the columns will line up correctly.

However, the example uses a 4MB .csv file with 50 columns and over 10,000 rows for a data source proving that it is possible to display an enormous table in an Android app with responsive two-way scrolling.
