Android : Can't Create Multiple ListViews In One Activity

Mar 23, 2009

I want to have multiple listviews in my activity. Every listview will have a different adapter and every item in the listview must be clickable (other actions for every listview).

So my problem now is that I can't create multiple clickable listviews. I have one listview like this <ListView android:id="@android:id/ list".. and the other listview looks like this <ListView android:id="@+id/ flightList"

The first listview looks like this in my activity hotelList = (ListView)findViewById(android.R.id.list);

the second: listView = (ListView) findViewById(R.id.flightList);

I can click on the first list and it does what it has to do, but i cant do anything with the second list.. probably because it hasn't the android:id/list declaration. does someone knows how I can solve this problem or other suggestions how I can get multiple lists in 1 activity.

Android : Multiple Handlers In A Single Activity

May 13, 2010

I've more than one Handlers in an Activity. I create all the handlers in the onCreate() of the main activity. My understanding is the handleMessage() method of each handler will never be called at the same time because all messages are put in the same queue (the Activity thread MessageQueue). Therefore, they will be executed in the order in which are put into the Queue. They will also be executed in the main activity thread. Is this correct ? Code...

Android : What Is Best Way To Do Multiple Listviews

May 15, 2010

I am writing a software that i have to drill down on content a lot. For example when the program starts a listview is displayed. When user clicks on an item, then a second listview must be displayed. For example:

Select Continent > Select Country > Select State > Select City > Select Address

What is the best way to do this (less memory, faster, easier to code etc)? To create multiple listviews with multiple adapters? Or 1 listview with multiple Adapters? Lists are loaded from an external XML File.
So far i am creating a new adapter and setting it to the listview. How do i create a second listview and after clicking on 1st listview displaying the second one, with animation. Any examples? Extend my class to ListActivity or Activity?

Android : ListViews With Multiple Item Layouts

Aug 5, 2010

I have a ListView on my ListActivity and I'd like the rows of the ListView to be 1 of 3 different layouts. The first item in my list is always going to use layout A, the second item in my list is always going to use layout B, and all subsequent items are going to use layout C.

Here is my getView function: Code...

R.id.label1 and R.id.label2 are TextViews on R.layout.layout_A. However, txtLabel1 and txtLabel2 are null after trying to set them. Why?

I stepped through this code in the debugger and it inflated the correct layout (R.layout.layout_A) and fell into the correct case below to set the R.id.label1 and R.id.label2 text. Also, if there is a better way to do this, please let me know.

Android : Scrolling Issue / Should I Use Multiple ListViews?

Apr 4, 2010

I have a RelativeLayout with different elements. I was planning to have two ListViews on it, but I have noticed there are some problems with scrolling. Since each ListView only shows a maximum of 5 rows should I try to make some kind of custom adapter to merge those ListViews? Or is it better to replace the ListView with a LinearLayout/RelativeLayout and add the rows as I get them manually? (like the first answer in here: http://stackoverflow.com/questions/1778485/android-listview-display-all-available-items-without-scroll-with-static-header ).

Which should be the proper way on doing this? or is there another way? Also, each row will have an OnClickListener.

Android : ListViews Getting Rendered Multiple Times

Mar 16, 2009

So the situation is this, I have a ListView that is embedded in two LinearLayout ViewGroups to form a screen. BaseAdapter.get View() (the implementation of the ListAdapter) is typically called n times (where n is numElements) to render the screen. The problem I have is this set of calls is being repeated for every ViewGroup that the list is contained in...So for a Layout like this:

-LinearLayout --Linearlayout ---ListView

The adapters get View() is being called n*3 times (3 = 1 for the parent LinerarLayout, one for the child LinearLayout and one for the List itself).

This is obviously a problem when the items in the List are expensive to build (even with recycling).

So I'm looking for some guidance on this, as the documentation doesn't seem to note this behavior from what I can see.

A small, basic example of the source is located on my post here http://www.anddev.org/listview_getting_rendered_multiple_times-t5290.... with more details Oswell as a ready made eclipse project(also attached below) if anyone is keen to try it out.

Android : How To Associate An Activity With An Item In XML ListViews In Droid?

Mar 22, 2010

I have a ListView that is populated using an XML file. However, I want each item, when clicked, to start a new Activity related to that item. I understand how to use OnItemClick to start a Toast that shows the selected item's text. However, since the ListView is populated from an XML there is not a specific Id for each item in the list. So, how would I associate an Activity with each item in the ListView when the items do not have Ids?

Android :: Want Multiple Activities In A Single View

Nov 19, 2010

Were looking into Android for writing a tablet based system. Part of the design is for the system to be as modular as possible. One aspect of this is to display any "STATUS" activities in a side view on the screen. It looks like I can use PackageManager queryIntentActivities() to find the activities that show status information. But, can I display these in a single view all at the same time (via a linear layout)? The activities would be installed in separate apk's (features). Can this be accomplished using ActivityGroup? Is this even allowed in Android? Everything I've read implies that Activities take the whole screen or float on top. This implies only one activity can be active at a time where as the design I'm thinking of uses the activities more like widgets.

Android :: Using Single Intent With Multiple Buttons

Aug 12, 2010

I have an android context menu with various selections and depending on the user selection I want to start an intent. The intent starts the same activity for all the buttons but will contain different String variables depending on the selection. I am currently using a switch, case methodology for my click listener but keep running into 'duplicate local variable' problems as I try to eliminate code repetition! If anyone could provide a-bit of pseudo-code that would be even better.

Android :: Best Practices For Creating Multiple App Versions From A Single Codebase?

May 4, 2010

Are there any viable approaches for creating multiple .APKs out of a single codebase? The apps may share the same code, but they could have different manifest files, different resources, or different external libraries (for example in an app with both free and paid versions, the free version could have a library for display ads). Ideally, this would be a single Eclipse project, with a way to specify which app to build/debug, and possibly a command line way to batch build everything.

Android : Back Button On Emulator When Multiple Activities Are There In Single Tab

Oct 13, 2010

I have created two tabs, say TAB1 and TAB2. For TAB1, i have loaded one Activity, say ActivityOne, into TAB1 as Code...

When we click on that button ActivityOne_One will be launched under same TAB1. In this application i have two problems:
1) If i want to go back to ActivityOne under same TAB1 by using traditional BACK button on emulator it is not working..
2)ActivityOne_One is launching with no animation(like sliding from right to left) effect.

If anyone know about any one of these, give your advice.
