Android : Multiple Listviews In Single Activity But Display At One Time
Apr 5, 2010I want to have multiple listviews in single activity. But only one listview should be displayed at one time. The listviews will be loaded dynamically. So, how can I fill all the four listviews at the same time and display only one.
If anyone knows the solution then please share it over here. I hope to get a quick response.
Android :: Want Multiple Activities In A Single View
Nov 19, 2010Were 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 : Back Button On Emulator When Multiple Activities Are There In Single Tab
Oct 13, 2010I 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.
Android :: Pros - Cons Of Multiple Activities In An App Vs One Activity - Multiple Views
Aug 16, 2010Are there design guidelines to help decide if an application with multiple views should be designed with multiple activities or just one activity and control the back button itself.
I've tried both. My most complex applications using one activity per screen. However, now that I'm successfully written an app with just one activity and handling the back button myself, I don't see any compelling reason to use multiple activities. The one activity application is much simpler and more straightforward.
What advantages of multiple activities am I missing?
Android :: Android - Accessing Single Database From Multiple Activities In Application
Dec 15, 2009I have a todo list type application that stores all of the note data in a sqlite3 database. Each activity in the application needs access to the database to edit different parts of the data in real time.
Currently, I have each activity open its own DBManager object (the helper class I created to manage the database). This is causing problems though and I would like a slightly more global access solution so I don't have to keep opening/closing/creating a database.
I'm considering several options, and would like to hear pros and cons of each as well as other suggestions.
Singleton style. Have a wrapper class that returns a reference to the only database manager so any activity that needs it can use it.
Static Manager. Have the manager class be entirely static members and have it open the database on load. Easily accessible by anyone that needs it (which is everyone).
Merger between 1 and 2. I could make a database manager class that initializes the member singleton instance of the database and all of the data manipulation methods were static. Then I wouldn't even need a reference to the singleton to access the database.

Android : Multiple Handlers In A Single Activity
May 13, 2010I'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 :: Should App's With Multiple Layouts Have Multiple Activities To Handle Each
Jul 1, 2010I'm planning to develop and app that presents the users with several different screens (of different information).
Was wondering what would be the best way to implement this?
Is it better to have separate XML layouts and an activity to display and allow the user to interact with each screen of data?
OR would handling all of these in the same activity be more efficient (and dynamically load / unload each layout)?

View 4 Replies View RelatedAndroid :: Manage Multiples Activities Under A Single Tab Of TabActivity?
Jul 8, 2010In my app, I have 5 tabs which contains activities. In each of them, I have to show differents screens. For example, the main activity of a tab is a listview, and when I click on one of its item, I want to display a second screen with an other listview, that will display an other screen when the user will select an item etc.
So I knew that activities in tabs are not easy to manage, but I really think that I needed this solution. Indeed, each screen must contain a back button, which will return to the previous screen, with the previous state (the same position in the list).
To start new activities inside the tabs, I used the technique described here http://gamma-point.com/content/android-how-have-multiple-activities-under-single-tab-tabactivity
It works mostly well, but I encounter a problem to go back to the previous activities. My solution at the moment consists in starting the previous activity like it's described on this website, but without any flag.
So here are my two real problems:
When I try to go back to the first and main activity of the tab, it seems that a new instance is created, even if I use the flag Intent.FLAG_ACTIVITY_CLEAR_TOP. So when I do several roundtrips between this activity and the next one, i obtain a StackErrorOverFlow.
Because the activities are accessible from differents activities, I have to memorize the parents activities all the time, by giving them in the intents. It's really heavy when I have a succession of 5 or 6 screens, I have to memorize the grand grand parent if the activity... I really appreciate if I just could call the last Activity started by the localActivityManager.

May 4, 2010Are 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.

Now the browser will be pushed to the 2nd position in the window order and Video will come to the first position. Is it possible that browser can have the control for active window and receive the key events though the video is the Top Most window.
