I've been asked to make an app that has a very VERY long data input form (we're talking around 50 fields here!). Thats a design constraint and there is absolutely no way for me to work around that.
What I'm trying to do is to display the form in a way thats easier on the user. My idea was to break the form into sections and somehow use an expandable list view to display the form. The list group would be the section name and the list items would be the input forms.
My problem is that since the form can contain different types of input fields (checkboxes, radio buttons, textfields etc) and since I'm new to android programming, I dont really know how to do this. All the online tutorials I can find are about simple uniform expandable lists. Can someone suggest me a good tutorial or an alternative to my idea?
I would look into using ExpandableListView as is, but create your own xml layout file for each list 'child' row, putting the field name and then a text input field for the value into it.
Have alook at this page where the author shows how you can put a 'checkbox' next to each list items row:

You have to use child layout view for achiving this.
follow below link and find the code,Inflating only one text view but u can inflate the complete layout(I personally used that thing in my code).
Expandable list view
What you're going to need to do is extend your BaseExpandableListAdapter and customize it to display all the various layout options. Specifically, it's going to be the getChildView() method that you'll have to do the most work in. Do some searches for customizing or extending the BaseExpandableListAdapter and you should find plenty to go by.
Also, take a look at the example from the SDK:

I'm doing a reminder application for Android that has an activity which is populated with inputs that depend on the category of the reminder. The amount of inputs (EditText) changes depending on the category, so im a little confused on how to tackle this case.
I propose 3 solutions here, but I'm not sure if there is a 4th solution or a better way to do it. I'm open to criticism. These are my choices:
I can make fragments for each category
Or I can make a common xml layout file that contains a number of inputs that reflect the category with most inputs, and find them programatically and assign them their properties
Or I can make the inputs programatically.
I'm trying to find the most elegant solution here. Thank you for your help.
What you can do is write all the inputs in one file,then set their visibility to hidden, and only programmatically change the visibility to show when you want it to. Tht way if you want to show three inputs, you can change the viibility of the three inputs and the rest of them would still be hidden, hence solving the issue.
Use some kind of adapter-based View. I recommend RecyclerView.
With it, you can covert your form objects into scalable View hierarchies in an elegant, efficient View, using an Adapter object.
You can use <include> to add your different screens and assign the visibility programatically
good evening , I need help about filling a list view from a MySQL Database,
i don't know how to do it becaus i'm beginner in android
i wanna icon and 3 text views the first is title bold and the second is the RIB and the last one is in the bottom and right of the list view
Your question is a bit too generic and not clearly defined. That's probably why it got down voted. I'd say your best bet is to start with the documentation. Start by reading about ListView and possibly Adapter and try it yourself. If you still have problems, ask a specific question about something you don't understand or can't get working. The best specific answer I can give is that you will need to define a custom adapter to create the item view you want. You will most likely want a layout xml for that item view.
I want to use a single layout for displaying different information.
Ihave a list view. When the user selects a item from the list view it should open the layout for that list item. List view contains the name and image of the entity.In the layout it should display all the other information. This single layout has to be used for displaying the information for all the entity of the list view as per the users selection.
Bst way to picturize it is the google play store. we have a list and according to our choice the same layout is used for displaying the information for all applications..
in the list view,layout the data will be fetched from internet.
pls help..
You are basically looking for a master detail flow i guess ...
Check THIS LINK which is exactly similar to what you want ... I think the selected answer here applies to you to your question too.
You just need to do it throught your java code i dont know what exactly you want to change so i cant provide a code but you may easly find some in this website. From a quick search i found this : Editing data in a List View item and it seems to be what you want.
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.
Good Morning All,
I am creating an application to display List of applications with their data usage.
I want my list to look similar to Traffic Counter Pro on android Market
I have also added the print-screen on my box.net as SOF does allow me to upload image
So Can someone direct me how to create ListView like this?
My second Question related to this how to create a tab style Activity.
Two examples that helped me a lot:
http://www.codemobiles.com/forum/viewtopic.php?t=876
and
http://android-developers.blogspot.com/2009/02/android-layout-tricks-1.html
i hope they are usefull to you.
You have to use custom ListView to embed images and format texts as given in the listview.
check out this example or this example or this example or even this example that gives you good understanding on listviews.
Good luck.
This is ListView which items consist of 4 Views objects, look through the tutorial of how to create ListViews and through the tutorial of how to create TabActivitys. And also use links suggested by #parag.
If you observe the screen shot carefully you can identify that group of these fields are available as list item.
They are
Application Icon
Application Name
Data Uploaded
Data Downloaded
Total Data Usage
So you have to create a layout with these fields as children with appropriate position and Use this custom layout as child layout for ListView.
I hope it may help you.
