I have a viewpager with some tabs. I always use the same fragment with a listview to load some String data into the listview. So far, so good. I now want to implement a searchview. And, I want to group the search results like whatsapp does. So the found listview items should be grouped by the tabs they were found in.
My question is: Which view does whatsapp use and how can I do so ?
Can I keep my simple listview or do I need some other stuff ? I thought about an expandable Listview, could this be a solution ?
Unfortunately, SO doesn't allow me to post an WA screenshot at this moment. But I think you know what I mean.
At the end of this day, I can say that my desired Grouping of Searchresults is definitely possible with an Expandable Listview.
You can hide the Group indicator and disable collapse so it looks like in whatsapp.

I am developing the following screen
The fourboxes next to each other are buttons. On clicking of the buttons I am changing the adapter of the listview.
Since the content above the listview took up lot of space I made the whole thing as an header and added it via code.
myPollsList = (ListView) findViewById(R.id.listArea);
myPollsList.addHeaderView(getLayoutInflater().inflate(R.layout.profile_listview_header, null));
Now I want to show some view when the list is empty. But if I do that then the header also goes away.
I am using this in a Activity and not a ListActivity. Any suggestions or workarounds for showing the header even when the list is empty ?
EDIT: Refer to my earlier question here ListView not getting space to show content on smaller screens . This is where someone suggested me to solve the problem by putting it as a header
I found a simple solution for this problem. If there's no elements for list and you are not adding the adapter, just add this:
mListView.setAdapter(null);
and the header will appear. It's easier than adding empty / fake item to the list.
So this is how I solved it. I had a custom adapter which was connected to the listview. When it found that it had zero items to display. It would add a fake empty view as an item to the list.
maybe you will like this Android addHeaderView disappears when no items in ListView
override/subclass your adapter to return false from isEmpty()
Don't use top layouts of button as header for list view.
So to adjust UI without using list header use weights.
Give parent Linear layout weight sum as 4 and 1, 1 to top Layouts and 2 for list view.
I'm programming an android app with a list displaying images and some additional information like title, place, etc...
I'm new to the android ecosystem and wondering what are the best practices to implement a list element which normally displays the mentioned information and turns into input fields on a press on the listelement.
Do I have to draw the display elements (e.g. TextField) and the edit element on top of each other and set visible for either display or input? How to handle this generally? Or do I replace the layout responsible for the list element altogether?
I know that for the simple case of a text there is a simple solution for making the EditText field look like an uneditable TextField. I'm, however, looking for a general answer covering broader cases than just a TextField.
Thanks!
you can make the elements of the listview a view flipper having two views.one you textview and other and edittext.
<ViewFlipper
...
<TextView
... />
<EditText
... />
/ViewFlipper>
Then in the onItemClickListener of the list items you can call flipper.showNext();
So, flipper works like, it shows only the first view defined in it and on the subsequent call of showNext() it displays the next view defined in it.
So if you have 2 elements in it, it will behave as the coin with two sides.
So in your situation there are a few ways you can achieve this.
First way is to build a layout which contains TextView and EditText and in first initialization your edit text won't be visible. And in your OnItemClick you have to hide your textview and show editext with value of your current data and option to edit.
The second way which I think is more user friendly is that you can show an AlertDialog after OnItemClick with custom layout where you can change the values and update the listview after user press Yes or do nothing is he selects No.
It depends on you which way you will do that, but I think the second option is the better one.
I have a UI design which should contain a text data and this can be dynamic so i need a scroll view after the TextView is over i need a list view, Now this list view onItemClick of a cell should expand and contract to show details, Any sample project or code from where i can achieve this UI design, Please help me with this one.
It is strongly not recommended to have Nested Views that scroll.
What you can do is have a TextView followed by the ListView. You can use expandable listView for your expansion requirement. All the examples are present in APIDemos shipped with Android SDK.
Try some of the stuff and get back for more help here.
I am trying to work with mouseover on a particular Item in my application by using the following command
{
ie.text_field(:xpath, "//a[contains(text(),'Deal')]").fire_event('onmouseover')
}
On doing mouseover on a item, two subitems are displayed.
Is there any way to capture the sub items which are part of the Item by doing mouseover with which we can report that our test is pass or fail.
Please suggest.
Additional Information :
If we take example,On the StackOver flow page, If i do mouseover on my name, i get a window where i see activity, privileges, Logout and other stuff. This is really what i was looking for. Is there a way to capture the items displayed on the window on doing mouseover.
I also tried to capture the subitems with the following :
{
text=ie.text_field(:xpath, "//a[contains(text(),'Deal')]").fire_event('onmouseover')
puts(text.inspect)
}
On doing this "text" value is displayed as 'nil'.
My general tactic for such things is a combination of using IRB and the IE Developer tool, or Firebug.
using IRB, type out (or cut and paste) the watir statement to fire the onmouseover command to the proper element on the page.
Then have the developer tool rescan the DOM (there's a little refresh icon you can click) The use the tool to point to an element to point to one of the items in the stuff exposed by the onmouseover. Using the info from that, you can then figure out how to address those elements to get the text from the proper div, etc.
If I do that here to the info that opens up when I float the mouse over my name I can find out that it is a table of class "profile-recent-summary" Furthermore I can then look at the way the table is made up and see for example that the 'today' reputation value is in the second cell on that row.. The row also has the text 'reputation' in it.. so
browser.table(:class, 'profile-recent-summary').row(:text, /reputation/).cell(:index, 2).flash
Should flash the cell I want (index might be 1 if using firewatir or webdriver) I can then replace the .flash with something else like .text if I want to get the text from that cell (which is actually inside a link that sits in the cell)..
without seeing your code, I would 'inspect' the element that you are trying to verify and when_present (text) assert that its true
I want to design one form that contains TextField and ListView in J2ME. But I don't know how to create this form. It is looked like Dictionary Form. Could anybody help me to do that?
You can't really do that with the basic UI controls in MIDP.
List can't contain TextField.
I would suggest looking at LWUIT since it has better controls.
Otherwise, if you don't need to display Images in your List, then you can use a Form containing both TextField and StringItem. Unfortunately, an ItemStateListener added to the Form will probably not give you as much information as a List.
Implementing the list yourself in a CustomItem means writing quite a bit of code but is doable.
If what you need is a TextField where you enter a search String and a List that displays the search result, I suggest using a TextBox first, then a List. Separate screens are by far the quickest solution here.
Edit: you can't use swing in j2me. what you can do is have just a textfield in a form, then add/remove StringItems to/from the Form when the user changes the content of the TextField. You should be able to rely on ItemStateListener to tell you when the textfield content changes.
