I am currently trying to create a tablet optimized version of my app. However, difficulties occur when i try to populate the screen with a listview that consist of THREE item columns.
Heres a brief illustration:
What is the best way to do this?
UPDATE
The problem is dont know how to setup a listview with 3 columns. In my phone version app, i use a simple listview where each item when clicked opens another activity. How to achieve such for 3 columns?
i think Grid view can be used in your case. Even it is a custom view you can still inflate layout and apply it for single item.
You can use LayoutInflater and inflate a sublayout from xml to create a multicolumn listview. Have a look at Multi Column ListView and this

How can i do?
Sorry for my poor english

The Android SDK does not provide a horizontally scrolling ListView. You can use an open source HorizontalListView.
See the BaseAdapter and CursorAdapter for populating your ListViews with child views that contain image/text.
here is a good example for horizontal list view

as for the vertical listview i think there will be no problem in it
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 was wondering how to implement the listview like the android market.
in the right hand panel a listview is divided into the two rows. This is very useful because it saves lot of space and user can look at almost double items in the listview at a time. how can I implement this ? any suggestions?
you can use GridView instead of ListView of two columns..
1. GridView
2. GridViewExample
Sample design :
The Android Market also uses the ViewPager to scroll between the pages. Here is an example on how you could implement it.
There is another question that is related to this one.Check the folling link, it might help you:
How to display a two column ListView in Android?
Modify you *.xml file to get what you want.
Good luck!
If you want to do this using listView, then each item (row) in the list view should consist of two views. You can do this using a relative layout (or linear layout) with two items side by side.
You can also implement this using a gridview having two columns.
This layout is a shelf with 3 books each row.
I current come up with gridview for displaying the books and manually add up the shelf bar. The problem occurs when there are more than 9 books and the layout is broken when scrolling the grid.
Could anyone suggest me another better way to deal with this layout. Thanks
I think you should set the background in each element (one shelf) instead of the setting the Grid container background (three shelf) ....
it's looking difficult in your case because it would has three images in a row ..So you need to try some this switch(position%3) in getView of adapter to set three different image
or
Use the ListView and Re-set the data in Array List so that each element has three books and you can make all three images clickable of that row and can make list row unclickable and unfocusable
I am trying to create a screen where I get two items from SharedPreferences and display them to the screen, and then display a list via an adapter.
What I am not sure about is how to structure the layout xml file for this. Any suggestions how to do that?
Thanks!
You can have the main layout with a listview. Then you can have a sub layout for each row of your list. This row layout, let's call it row_layout.xml may have two text areas if your items are text or it may have a text area and a checkbox button if that's what you want. Basically, whatever you want to display in a single row of your list.
Read up a tutorial, here's one: http://www.vogella.de/articles/AndroidListView/article.html
Take a look # MergeAdapter, you can also create a view only listitem and add these item as header to the list
I am not sure what you mean. Are you asking for examples of layouts with two textviews that can be updated via sharedprefs, with a ListView in the activity? Or just suggestions? An easy way to get started would be to use the Eclipse Android plugin that has a layout designer in it. Here is a tutorial on how to use it http://mobile.tutsplus.com/tutorials/android/android-layout/ Its pretty easy and straight forward.
