Android : Switching Between Multiple Views In A ViewFlipper

Jul 19, 2010

I have an application using ListView inside Tabs, and I'd like to switch to a separate View(data collection widget) on clicking an item in the List.I'm adding each List's row's children to a ViewFlipper and the items are added at runtime so there is no definite number of views. As such, i would want to navigate/switch to a particular View in the ViewFlipper.Any pointers?

Android :: Multiple Activities Or Switching Views Manually

Jan 15, 2010

I have developed some apps for Android, and this questions stays always:

How should I structure my UI? Should I launch activity after activity and leave the phone to make the "back" button, or should I choose more optimized, but more complex to implement, way with switching manually Views and then manually doing the "Back" button functionality?

Android :: Switching Views With RadioButton And Saving Views In Bundle

Mar 6, 2010

I have the following XML code:.................

The idea is to change the views, whenever I press one of the radio buttons. When I press a button the first time everything works out fine, but the second time I press a button, I get an IllegalStateException, and I can't quite see why I'm getting this.

Also, the Activity seems to set all my global variables to null, which is why I have to create them every time I switch from portrait to landscape or vice versa. So I would like to know if there is a way I can save my views in the Bundle, or any other way in which I can permanently save my views, so I don't have to add or create them every time, I flip the phone. And whenever I flip the phone, it seems that it rereads the main XML file, causing the RadioGroup to be set to 2D even if the 3D button is checked. This is because I've said the 2D button to be checked from when the app is first created, but I would like to also save the state of that RadioGroup.

Can I use ViewSwither instead of this case?

Android :: Get Bitmap Of All Views In ViewFlipper?

Apr 6, 2010

I need to take the Bitmap of all the Views in ViewFlipper. But it gives me the Bitmap of only the current content on the screen. Is there any way of getting Bitmap of all the Views in the ViewFlipper.

Or is there any other way around to get the Bitmap of all the Views. I have four views and need to load them at the same time and get their Bitmap so that I can resize it and later display with Gallery.

I hope to get a quick response this time around.

Android :: ViewFlipper & Multiple Images?

Oct 14, 2010

I need to include multiple images in my Android app. It's like an image viewer/slideshow. Currently I switch between pictures from /drawable-mdpi dir simply with ImageView and adapter, using gestures to left/right. Works but nothing impresive :/

Basically I could use something like Android (2.1) gallery with some image show animation.

1st question: what's the best way to include many (50-100) fullscreen images in App?

2nd: is it possible to use ViewFlipper animations directly to images? or do i have to somehow populate Views?

Android :: Pros - Cons Of Multiple Activities In An App Vs One Activity - Multiple Views

Aug 16, 2010

Are 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?

Feb 18, 2010

I'm working on an application using xml layouts.

I wish to know which is better:
1. Use few activities and change its contentview
2. Use an activity for each 'view' needed

If both works, in which case which option would be better?

Android :: Switching Between Views Without Loosing OnClickListeners

Aug 29, 2010

On my application I'm developing, the main.xml layout (the default layout of my app) has a few buttons that have been assigned onClickListeners (not the implementation way). One of those buttons I want to have the ability to take you to another view. On the other view (preview.xml), there's another button that takes you back to the main.xml view. I've used setContentView in the onClickListeners of those buttons and this works fine so far, but after you click the button that takes you back to main.xml, the buttons on main.xml have lost their onClick functionalities. How can I get this to work right? I presume using setContentView isn't the right way to do this?

Switching Between Views With Sliding Menu?

Jul 14, 2013

I'm currently developing an Android-app, in which I have already implemented an Slidingmenu (jfeinstein10's library). As above-views I have several activities I'd like to switch between with the menu-items in my Slidingmenu. For the most part, these activities consist of two fragments, a list and a content-view. In landscape-mode both are displayed, in portrait-mode only the list. Currently I'm switching between these activities with intents, which is not a very pretty "solution". How should I implement this?

I start a browser and from the browser,I start a video which occupies only a small part of the screen,say the bottom right corner.

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.

Android :: Multiple Surface Views

May 20, 2010

I am working on a graphics application in Android. I have a question regarding MULTIPLE SURFACE VIEWS. Can I be rendering multiple surface views at the same time. Initially, when I had two surface views in the same activity, it didn't seem to work, as it used to show only one at any time. But, with one surface view attached to one activity, is there any way I can keep the background activity's Surface View alive so that both the surfaces get rendered together?

Android :: Multiple Views For For Row In ListView

Jan 17, 2010

I have a ListView that could have 4 different views for a row depending on the data for the row. I have the ListView working correctly overriding getViewTypeCount and getItemViewTYpe. I originally was trying to dynamiclly update the view type count as new views were inflated by forcing calls to getViewTypeCount because it was possible that maybe one or two views may be all that would be needed. The app never functioned correctly crashing after there was more than one view added. The problem was fixed by setting getViewTypeCount to always return 4. I noticed getViewTypeCount is automatically called on app start-up and never called again unless a force call is made. So I'm just curious if this can be changed dynamically or do you need to know the number of max views you can possibly have and override getViewTypeCount to return that max value.

Android :: How To Use Multiple Map Activities / Views?

Jul 31, 2010

My situation is the following: I have written one MapActivity class that is able to display a set of places as well as single places. On startup, the application creates an instance of this MapActivity and displays multiple places. If the user clicks on a certain place, then a new Activity is launched that shows the details of the selected place. This activity has a menu item that allows the user to view the place on a map - this causes that a new instance of the MapActivity is created, except that now only this single place is displayed.

The problem now is that if the user navigates back to the first MapActivity (the one that shows multiple places) the tiles won't be loaded anymore + sometimes OutOfMemoryErrors are encountered. According to the Android JavaDocs, it is only possible to have one MapActivity per process. However, I don't want to define my MapActivity as a singleInstance/singleTask, since the user should always be able to navigate back to the first MapActivity that shows multiple places. I have seen that the Google Places app (which has come with Google Map 4.4) for Android uses multiple MapActivity instances. How is this possible?

Android :: Application With Multiple Views - Best Practice For Structure?

Jun 20, 2010

I am new to developing for android. I have a question regarding some best practices. My app is like a dashboard from which multiple different "sub-activities" can be started and done. I am wondering what is the best way to structure the app. One way is to have different layouts and load and unload them appropriately. The other is to start new activities using intents. At least this is what I have gathered from what I have read.

Android :: Implement Multiple Views That React To OnTouch?

Oct 10, 2010

Let's say I have MyActivity and inside my onCreate method I initialize MyBackgroundView, then MyPlayer1View then MyPlayer2View. I want to be able to touch the screen, figure out if I have touched Player1 or Player2 and then respond with changes to the players if I have touched them.

My problem is, where do I put the onTouchListener? Can only MyBackgroundView listen for touches, or can the players listen for touches too? If MyBackgroundView can only accept touches, do I need to call view.ontouchlistener that says, you have touched me, and I have a player at those coordinates, so I'll pass the motion event to the player and let it handle it? Or do call view.ontouchlistener in each of the players that says, you've touched me, now I will react to the motion event?

I want to know the best way to do this without creating new buttons for every activity. I have been around programming (C++/C#) for many years but am pretty new to Android and Java so if someone can point me in a general direction.

Android : UI Design Suggestions For Display And Switching Between Multiple Layouts

Jun 26, 2010

I'm trying to create an app that offers the user 3 different kinds of layouts. The only common portion for all 3 would be the TextView (located at the top) that would display information specific to the currently displayed layout and 3 buttons to select the required layouts.

Is there some way we can create this UI in XML to keep only one constant part(the upper TextView) and dynamically display any one of the 3 layouts below it?
Would it be better to create separate XML's for each of the layouts (each including the upper TextView in them)?
OR would doing this via code be better?

Fast switching between the 3 layouts is important. TIA

[EDIT 1]
Actually they are 3 different layouts, with several "child" layouts and views within each of them. Could a ViewFlipper be used for switching between these? I was thinking that a ViewFlipper was only for switching between View elements?

I do have them in individual XML's right now but am looking for some way to load and unload them fast. Not sure how to do the hiding thing, will try reading up on that. [/EDIT 1]

Android :: Access Views Inside Layout When I Reuse It Multiple Times?

Aug 6, 2010

I have read the Android UI trick 2 on Android developers, which tells people how to include a layout in another layout file multiple times, and give these included layouts different id. However, the sample here is overwriting the layout id, not the id of the views IN this layout. For example, if the workspace_screen.xml looks like this: And I include it three times in another layout file. Do I end up with three TextViews with id firstText, and another three with secondText? Isn't there an id collision? And how do I find the secondText TextView in the third included layout with findViewById? What should I input in the findViewById method?

Multiple Image Views In Linear Layout?

Jun 11, 2013

I am using a linear layout to draw a scalable background in my app. I am then defining multiple imageviews inside the linear layout, all of which are PNGs containing a transparency layer. I am wanting to overlay these transparent imageviews on top of the background. My issue is that only the first defined imageview shows on top of the background, any subsequent imageviews do not appear.

CODE: Note that imgSen1 appears properly with transparency overlaid on the background. imgSen2 does not appear. If I define imgSen2 first, and imgSen1 second, imgSen2 then appears properly, as if only the first defined imageview can be seen. I would like to have multiple imageviews with transparency overlaying the background.

<LinearLayout
android:layout_width="627dp"
android:layout_height="436dp"[code]...

If the above is not possible are their any decent widgets that I can use for switching between APNs?

My phone is a Note 2 SGH-I317M with JB4.1.2.
