Android :: Header - Views And Buttons - How To Attach Listeners To Buttons In A Header That Does Not Have Its Own Activity

Jan 6, 2010

I have touched on this question here, where Christopher gave an answer to this, but I dont really get it so I thought its time to make it a real question, not just a "follow up" =)

As it stands, the application Im writing has 4 different screens:
1. Screen 1 - list of nodes (main screen)
2. Screen 2 - options menu, tableLayout with buttons
3. Screen 3 - navigation
4. Screen 4 - text details on version etc

These screens can be navigated to/from using a "header" View that is placed on top. the header then has 4 different buttons:

+--------------------+
| menu with buttons |
+--------------------+
| |
| |
| |
| C O N T E N T |
| |
| |
| |
+--------------------+

The header is just an XML-file (header.xml) with a few buttons. That header.xml is the included in the Layouts using the include-markup. For example, the main.xml has the line:

<include layout="@layout/header"></include>

The header show up alright, but the question is - what is the correct approach to attach OnClickListeners for the buttons in the header?

Christopher pointed out that you could create an Activity class and do the hooks there, like this:

CODE:............

First, I cant make it work since the method setupHeaderButtons isnt accessible from FirstActivity.
Secondly, is this the right way to go at it?

Android :: Listviews - Header And Footer Views

Jan 7, 2010

In my ListActivity, I need header and footer views (on the top and bottom of the list) to be used as previous page and next page buttons on my list, respectively, because I want to display only 20 items at a time.

I set my header and foot views by doing:

CODE:............

This works fine, but I need to dynamically remove and add these header and footer views, because some pages of my list may not have a next page button or a previous page button.

The problem is, I cannot call addHeaderView or addFooterView after I have called setListAdapter.

Android :: Start External App / Activity And Add My Own Header?

Jan 16, 2010

I am using Sygic Navigation on my HTC Hero. I can start it by calling the correct intent as I described here. Now, Sygic starts in fullscreen-mode and I cannot use the BACK-button to go back to my previous Activity (dont ask me why).

The question is: is there some trick or way so I can control how that Sygic Activity is started? I want to add my own "header" on top; the header contains my buttons for navigation. It would be great if I could add that header, then have Sygic below that (as the "content" then, as shown here).

Android :: Placing Buttons - Place Four Buttons Near Top - Left - Bottom - Right Edge Of The Screen

I am not able to find out the perfect layout(viewgroup) to place four buttons as shown in the attached image. Basically, i want to place four buttons near the top/left/bottom/right edge of the screen. AbsoluteLayout helped, but it is deprecated (It is also better to avoid AbsoluteLayout as it is not very flexible for orientation changes)

Android :: Static Header In ListView

Jun 12, 2010

I have a ListView with several columns and I need a header row at the very top that labels each of these columns that *does not* scroll with the rest of the ListView. I am using addHeaderView right now, but I've ran into 2 problems:

1) The header scrolls. I need it outside of scrolling so that it's always "floating" on top.

2) Each column in the header isn't lining up with the columns in the listview. I can make the header columns and data columns all line up perfectly if they're all in one big TableLayout, but how would I get the header to be outside of the scrollview yet also stay uniform and inline with the data columns?

Android :: Color Of A ListView Header

Jul 26, 2010

Is there any way to set the background color of a ListView header? I've tried calling setBackgroundColor on the header view, and I've tried android:colorBackground in the xml.

Also what exactly is the difference between a ListView header and a standard item in the list. I notice that by default a header can be selected, which makes me think there is no difference.

Android :: ListView Header Taking Up A Position?

Oct 26, 2010

I've just added a header to my ListView and I have to change a bunch of code because the header essentially becomes position 0 (Meaning the Cursor indices of my CursorAdapter do not line up with the indicies of the list. They are off by 1 now). Why? This seems a bit silly to me.

The only reason I can come up with is that a developer may want to access the header. Fine. Provide something like getListView().getHeader().

Android :: Injecting HTTP Header Into All Requests By Emulator

Mar 17, 2009

Is there an easy way to inject a header into all HTTP request sent from the emulator, including HTTP requests made by my app and also by the built-in web browser? I need this ability to model the behavior of a carrier gateway. I tried running the emulator through Fiddler as a proxy because I know how to manipulate HTTP requests in Fiddler, but that that didn't work. The emulator was successfully able to make the first HTTP request, but choked on subsequent ones. Reading this list, it seems that getting the emulator to use a proxy is not is not that easy. If this is the only way to do what I need, then I'll certainly give it another shot and post details about any problems I encounter. I am just wondering if perhaps there is an easier way to inject a header.
