There is a requirement to have not-so-trivial dynamic list, each record of which consists of several columns (texts, buttons). It should look something like:
Text11 Text12 Button1 Button2
Text21 Text22 Button1 Button2
...
At first obvious way to accomplish that seemed to be TableLayout
. I was expecting to have layout/styling data specified in res/layout/*.xml and to populate it with some dataset from java code (as with ListView
, for which 开发者_JAVA百科its possible to specify TextView
of item in *.xml and bind it to some array using ArrayAdapter
). But after playing for a while, all I found to be possible is fully populating TableLayout
programatically. Still, creating TableRow
by TableRow
and setting layout attributes directly in java code doesn't seem elegant enough.
So the question is: am I at the right path? Is TableLayout
really best View to accomplish that? Maybe it's more appropriate to extend ListView
or something else to meet such requirements?
Using ListView and ArrayAdapter you can do more complicated layouts than just a TextView. You could specify a LinearLayout with 2 TextViews and 2 Buttons for each row in the List.
here's a similar question Android: ListView elements with multiple clickable buttons
IMHO it depends on the amount of your data you need to render.
Build layout dinamically via inflate/addView is a quite simple task but is also more slow than using a custom adapter. with a custom adapter you can reuse the convertView parameter and then set the values more efficiently
