Can I set a code that doesn't change the orientation of the screen of my app if I turn the phone sideways? I tried making a new main.xml file in the layout-land folder, and it just looks weird. So, the screen doesn't turn when the oreintation is changed?

I am trying to create a very simple application (part of my learning program), vertically oriented, with an EditText at the top that receives a URL, and two buttons side by side just below that say "Get Image" or "Get Text" depending on the URL typed in (.html vs. .png, for example). The resulting elements may be later scavanged for use in a real app. I know that ScrollView can have only one child. Conceptually, I want the rest of the screen to be a vertically oriented content region for displaying either the text (TextView) of the URL and "Get Text" was clicked or the image (ImageView) in the case where it was an image and "Get Image" was clicked. I tried to do this (pseudocode) in main.xml:
<LinearLayout> <EditText /> --where to type the URL
<Button /> --click to treat URL as text
<Button /> --click to treat URL as image
<FrameLayout> --(used to be ScrollView) <LinearLayout>
<TextView /> --content region occupied by either text
<ImageView /> --or an image (but not both)
</LinearLayout> </FrameLayout> </LinearLayout>
In order not to violate the single-child requirement. However, this doesn't work and for now I'm not finding any sample out there that clues me in to how best to accomplish this. The last complaint I got while debugging was:
Caused by: java.lang.ClassCastException: android.widget.TextView
I have played around a bit with the xml files for creating layouts and can't explain the behaviour of layout_weight when using it in a LinearLayout that has orientation="vertical"
When creating a layout that is horizontal everything follows the documentation, that a child would get more space if it's has the highest value.
But the following code for vertical orientation, give more space to the item with lowest weight.
CODE:..........
And the question is: Is this a bug or just a feature that maybe need more documentation?
I have a Gridview, include hundred of items (thumbnail images). I set a multi-select mode, in this mode, user just need to swipe his finger to start selecting multiple items (this case, gridview can not be scrolled). And in a normal touch, Gridview still can vertically scroll for user to see other thumbnails and continue selecting.
View 2 Replies View RelatedI am a C# developer and getting started with Android. I am attempting to duplicate a couple applications I already have in VS. The project is made of 2 executables and 1 common assembly. The 2 executables contain the application specific logic while the common contains centralized forms and logic (such as login form). I am using Eclipse. So how can I accomplish this layout?
View 1 Replies View RelatedI have created an activity for my game which handles all orientation changes by itself and has a fixed "portrait" layout. Actually it uses the accelerometer and is rendered using 2D canvas methods. If the level has been completed I show up a highscore dialog in which the user can enter his name. The dialog is floating above the underlying level screen which gets blurred out nicely. This generally works.
Problem is that the dialog does not get rotated if the orientation of the phone changes. So even if the keyboard is exposed the dialog is shown in portrait mode instead of landscape. I have tried to use an activity with dialog theme instead but the behavior didn't change. After several tries it seems that I have found the reason for this: Once there's an activity with fixed orientation in the activity stack then all subsequent activities keep this orientation, too. They will not react on orientation changes anymore (e.g. if the keyboard gets exposed).
After upgrading to 1.5 SDK the described behavior changed a little bit. Now at subactivities indead react on orientation changes like expected. However, the need to have an opaque background! That means that neither dialogs nor activities with dialog theme will work. Those will stick with the orientation of the underlaying activity. So my workaround is to first start a sub-activity with an opaque black background. This activity then shows my highscore dialog on top. It looks quite okay but I wonder if there's a better solution? Is it possible to show a dialog above a fixed portrait or landscape activity which automatically adapts to orientation changes?
Somethings I'll have an? .xml file selected when I compile a project, only to have a? .out.xml generated. Deleting the file doesn't clear the error, and Eclipse won't compile the project. It just reports that your project contains errors. The solution is to go to Project/Clean. This will clear the error in the project and allow it to compile.

View 1 Replies View RelatedI have 2 android projects out of which I modified one to work as a library. I want the main project to refer to this library to perform few functions. While this scenario works just as expected, I want to introduce one more functionality. I want to link this library project with another just a java project which has code common to both Android and Blackberry applications. This second part however doesn't seem to work and throws "The application <appname> (<package name>) has stopped unexpectedly. Please try again" with a ForceClose button. I would greatly appreciate if someone can give a brief information on how to make this work.
View 2 Replies View RelatedI followed the instructions here on how to create an Android library project, and use it in an Android application:
http://developer.android.com/guide/developing/eclipse-adt.html
But it is not working. I can see the library project is added to my application but I cannot reference anything in it because it won't build. The R.java file from the lib is NOT being added to my application project, so the lib project contains tons of errors, everywhere it tries to reference it's own R.java file.
I don't know if this has anything to do with it, but in the console there are messages stating that the there is "No resource identifier found for attribute 'X' in package 'Lib Package'. My library package has a a few styleable attributes defined for a custom view I made, all of which are being complained about in this console message. The library builds just fine, and I don't get those messages in the console until I hook the library to my application, so I don't know what's up with this.
I understand how to force a specific orientation per activity in the android manifest. I would like to know if it is possible to allow the keyboard to change orientation even though the activity(the layout really) must remain unchanged.
View 1 Replies View RelatedWhen I right click the project in the eclipse, select "Properties". In the property page, select Android. According to the document, you can add the library project through that page. But my problem is that, there is no library information on the page. It only lists "project build target"

View 4 Replies View RelatedI have a problem with working with the ORIENTATION values of the SensorManager. I would like to have some kind of 360°-value which directly shows me if the phone is in normal portrait (0°), landscape, portrait turned around (180°) or anything in between. So I could have, for example, an arrow that points to the floor (like gravity would do with a plummet) all the time, no matter how I tilt (sidewards) the phone. I thought this would be easy, but I'm pretty confused at the moment.
First of all, the X value of the orientation-array seems to correspondent with how I turn the phone, BUT: if it's completely uprightly standing, this value is about 60° ... why not 0° (or 90°, 180°, 270°), as I would expect?
Second: The value resets if I turn the phone and Android automatically changes screen orientation. So both in Portrait and in Landscape mode it will be sth. like 60° when the phone is in a 0° angel in real world. I set "android:screenOrientation" to "landscape" but this doesn't help anything :/
I want the app NOT to change orientation when I turn the phone, but I want it to get a continuous orientation value when I tilt the phone.

In an effort to reduce duplication, I have my app's workspace split into 3 projects:
Main (A library project, where all of the common code lives)
Free (To make the free version)
Paid (To make the paid version)
Behavior in the free version and the paid version must differ sometimes. How can I "call into" the final projects from the library project? Here is some sample psuedo-code to illustrate my question: Code...
