Android : Add Couple Of Command Buttons For Creating Multiple Layouts

Mar 25, 2009

I am new to android and trying to create a customized list. Every item in the list has TextView and one Ratingbar. I now want add a couple of command buttons at the end of the list (like BACK, HOME, , NEXT). When I add these extra views to the layout xml file then they get added along with every item in the list. I think there should be another layout defined for the buttons to be displayed separate from the list. Anyone has an idea on how to do this?

Android :: Multiple Activites That Share 75% Of Layout - Layouts Within Layouts?

Sep 6, 2010

I'm creating a game where there's a screen that, for the most part, is shared by four different activites - but a key portion of the screen will be completely different, depending upon which activity is active. Basically, on the left will be an image of the player and along the bottom there will be a row of buttons (let's say for Armour, Weapons, Magic, Skills). This leaves the top-right portion, which will need to dynamically change to represent the button pressed. (So, one moment the top-right portion is the armour selection activity, and the next it's the weapon selection activity, and so on.)

Is this possible? Can I have a layout within a layout and dynamically point the nested layout at a (nested) layout.xml of my choosing? Or, am I looking at just duplicating most of the layout four times (for the four different activities?) Or, am I going to be looking at linking the four activities to a (the top-right) view component, and then having to dynamically construct all of *that* view's child views based on the currently active activity? Well, that's about as much sense as I can make this question make.

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

Jul 29, 2009

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 :: Where Is Metamodel Located?

Apr 16, 2010

I would like to use Android for Model-Driven-Software-Development.

For this, I need to locate the Android Model in the SDK. I already searched a while for it, but were not able to find it. Has anyone an idea where it could be?

Is it possible, that it is the AndroidManifest.xml-File in the folder android-sdk-platformsandroid-xandroid.jar? After unpacking this file, I am not able to open that file correctly on Windows XP, because a lot of characters have the wrong character set.

Or is it also possible, that it is only located in the source code?

Android :: Where Are Application Files Located?

Oct 30, 2010

I have a new Galaxy S. If I go to Market and install an application, everything is done automatically without giving me options.

So, my questions:
a. What is/are the files that are downloaded?
b. Where are files saved to?
c. What happens during installation? Is there just one binary? Or a binary with lots of other files? How can I find out the files that belong to a particular application.

If it is a paid application, how can I save it so that I can reinstall again. I am having so much trouble learning this new phone that I have to restore it to factory state already twice on the first day.

Android :: Communication Between Two Emulators Located On Two PCs Connected Via LAN

Jun 4, 2009

I am trying to port a VoIP application based on SIP protocol to android.

I want to test this application first on two emulators running on two different PCs connected via LAN.

The problem is that, the communication is not happening when I run the application on two PCs. The same application works when I run it's non-android version on the same PC's.

I have identified the following problem. Let's say there are two computers C1(192.168.1.101), C2(192.168.1.102) connected in a LAN.

Emulator E1 is running on C1 Emulator E2 is running on C2

The application uses UDP protocol and the port being used is 5060 on both computers.

I have setup port forwarding on both the emulators. This is the command used for that in Android console. redir add udp:5060:5060

When we make a voip call from E1 with the URL 192.168.1.102:5060, then E2 responds to the call, but what ever E2 sends in response is not coming back to E1, and hence E1 is timing out.

When I observed the log files, actually E2 is sending the response to 10.0.2.2:5060, which is the C2's loop back address(127.0.0.1). How do we resolve this issue?

I have gone through the developer guide where they have mentioned about two emulators communicating on single PC. But looks like this concept doesn't work when we run emulators on two different computers.

I tried 'redir' command for port forwarding and added INTERNET permission, still it doesn't work.

My question is, Is it possible to implement this communication on two emulators? and if yes, How to do this?

Android : Possible To Edit Phone Number Located On Sim Card?

Oct 31, 2010

I know it is possible to use TelephonyManager to get information like: service state, device ID, Sim Operator, etc...
Is it possible to edit some of this information?

Couldn't find .set() functions on Android.com documentation but I've found the GSMPhone.java source code which includes functions like .setNumber1Number() (used to set/edit the number?).

I basically want to know if it's possible to edit the phone number located on Sim card (Settings->About->Status->My Phone Number).

Appreciate any answer, even a simple "NO", if it's indeed impossible.

Android :: Layouts On Top Of Each Other

Sep 21, 2010

If I first set the content view to my xml layout using setContentView(R.layout.main); and then add another content view using addContentView(layout, params), the content views overlap each other. I want the second content view to position itself directly under the first one. Is it possible or do I need to combine the xml and the programatically created layouts in some way? Both of the layouts are linear.

Android :: Call Non Static Method (Located In Main Class) From Different One

Oct 18, 2010

I've been trying to call a non-static method, located in my main application Class, from the Preferences Class. Because the method I call is not static, I instantiate the main class and then try to call the specific method I want but it's force closing.

Preferences.class (from where I call the method):
Preference sorted = (Preference) findPreference("sortPref");
sorted.setOnPreferenceChangeListener(new Preference.OnPreferenceChangeListener() {
public boolean onPreferenceChange(Preference preference, Object newValue) {
Object d = new Dmarks();
((Dmarks) d).queryBookmarks();
return true;
}});
the Dmarks.class method I call:
public void queryBookmarks() {
Toast.makeText(context, Toast.LENGTH_LONG).show();
//context is not null and the Toast is working if I call it from Dmarks.class }

The Logcat:

Android :: Mix 2D Graphics With Layouts

Apr 26, 2009

I'd like to build an activity that is mixing layouts with 2D graphics. So for example, would like to introduce an edittext with an integer value and based on that value the size of a circle is dynamically adjusted and drawn. Any idea how to do this?

For plain graphics I am using this approach here - but how can it be expanded to cover Android layouts (buttons, editboxes, textviews, radiobuttons, etc.)?

Android : Animation Across Two Layouts?

Aug 10, 2009

I've met a problem with animation when tried to make a View to perform the animation which should cross 2 layouts, e.g. make a translate animation so a view could move down to the TableRow below. This trick works fine when i try to move a view within a single TableRow but not when i try to move it up or down. I've also discovered that if i create a single RelativeLayout and apply the same animation there, it works fine, but i can't arrange all the components i need on the screen. Could anybody please provide me any hints about it?

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 :: Different Screen Sizes X Different Layouts

Apr 27, 2010

supporting multiple screens (sizes and resolutions). Ive searched not only this forum but many different websites and the android documentation but Im probably doing a small mistake so things are not working properly.

Well, my main layout was designed with a HVGA screen, and it works great. When I try the same app on a WVGA, FWVGA, WQVGA or FWQVGA, I always get an unused space in the end of the layout because the screen s "heightnes" is proportionally bigger than HVGAs.

So I consulted the documentation and decided to give a try on resource qualifiers, so I then created a nonsense UI and placed it on layout- large, created a new AVD using the WVGA skin and launched the app. Well, all I got was my old and not well stretched layout. The same happened to a FWVGA AVD.

This is the first problem. The second is: medium high density medium size screens and medium density large screens have the same resolution: how can I create a layout that is loaded for both, but not for (for example) medium size medium density or small size medium density screens?

Android :: Rules For Inflating Layouts

Sep 28, 2009

i'm running into some issues inflating layouts and i wonder whether i have something basic wrong.i have a ListView with a custom adapter etc, and of course the item View is custom too. i've been creating the item View in code, and everything works fine, including recycling them and all that. great.but i want to move the View into a resource, where all good Android views live, and weirdness is happening.in the ListView's getView(), i get my inflater and inflate the view by ID. the view itself has its own XML file. i can inflate the top view, but i can't find anything by ID, and when asked for its children, nothing comes back.are there funky rules for inflating views this way? is there a convention for how this should be done inside a ListView?

Android :: Swap XML Layouts During Runtime?

Jul 27, 2010

Is it possible to load my main.xml layout file in onCreate() and then later in the app, switch to a new XML layout? I've tried placing setContentView() later on in the app but that seems to not actually set the new View because my references to objects in the newly set xml layout file are returning as null. I've tried doing some layout inflating using the LayoutInflater but I'm having no luck (I'm probably doing something wrong)... So is there any other way to swap layout xml layouts at runtime?

Android :: Way To Inflate Layouts With Different Density?

Oct 21, 2010

I'm wondering if it is possible to inflate a layout using a different density value than the default system density. I have a high density layout, which looks good on the Galaxy Tab (1024x600px, hdpi) and I like to use the same layout on another tablet with the same pixel resolution but medium density. The mdpi layout which is used works on the device but the screen just looks really empty and I would prefer to scale things up. So is there a xml argument for scaling the layout, maybe something similar to Bitmap.Options.targetDensity. Or could this be done with a new LayoutInflater class?
