I have a layout xml . I would like to do that in java programming. code...
I've recently knocked up a server/client app for Windows & Android that allows one to send a file from Windows to an android phone over a socket connection. It works great for a single file but trying to send multiple files over in a single stream is causing me problems. I've also realised that aside from the binary data, I will need to send messages over the socket to indicate error states and other application messages. I have little experience with network programming and and wondering what is the best way forward.Basically the C# server side of the app just goes into a listening state and uses Socket.SendFile to transmit the file. On Android I use the standard Java Socket.getInputStream() to receive the file. That works great for a single file transfer, but how should I handle multiple files and error/messaging information? Do I need to use a different socket for each file? Should I be using a higher level framework to handle this or can I send everything over the single socket? Any other suggestions for frameworks or learning materials?
View 1 Replies View RelatedI have been seeking beginner learning books in Android, and of course found out that I should learn Java first. So I began studying Java and now I am quite comfortable with objects, classes, inheritance, interfaces, and just moved onto Layouts in Swing as well as Swing Features. But I am starting to wonder.... do I know enough about Java now? Can I start programming Android yet?
Of course I can keep going in Java, but have been itching to begin programming Android apps.
Any definitive answer here about how much Java I need to know before Android?
I am new to Java and I referred regarding my question on the Net but not quite Satisfied. I want to know what the "Utility Class" in Java is?
View 3 Replies View RelatedThere are the following layout options to create interfaces for android.
AbsoluteLayout
FrameLayout
LinearLayout
TableLayout
RelativeLayout (and some more)
Which of the following is most suitable for designing simple games? Guessing that the absoluteLayout is easiest, but will it be problems with different screen sizes? What do you recommend?
I am a Java professional. Now I'd like to write an application for the Android platform.
What is the initial step I need to take?
How does my Java programming experience help in this case?
As the title says i'm new to the Android community, and i don't have much experience on the development side either. but i am very interested in getting started. I see that Android apps are based off of Java... So would it be better for me to learn Java before getting started with the SDK and eclipse? Or is it just the same to jump right in on App development and learn on the fly?

Also if in any way Android code is similar, then will it be hard to bring the iPhone (Xcode) files, or copy and paste my iPhone code into the Android code.

However before i even start to code this, Im a little confused about sockets and their performance. First of all, are sockets meant for many(1000+) clients connecting to one socket (say port 2202) on one server? How is the performance if all there waiting for is basically a ping, or something such that when these clients receive this "ping" they can go get some new data.

Eclipse 3.4 The problem is I have a project in workspace that has been developed under JDK 1.6.I don't really want to switch back to 1.5 ( i' would have to clean up a LOT of @Override ) but if i work with this project, after couple of rebuilds - eclipse layout editor not able to display preview.

View 2 Replies View RelatedOk o my program i prefer to make the layout in java but i was wondering is it more efficient to make it in xml? i dont wanna test both and see whats faster but it feels like when my program call the oncreate (which is where all my layout building code is) takes about 2 secs to load, will loading a layout from xml be faster?
Also a second question, i know you can allocate two different layouts (one per landscape or portrait) but does it till rerun oncreate when you do this and rotate? i ask because im considering not using landscape at all in my app however it would be usefull in a few situations like text entry but is there a way to jump to lanscape without calling oncreate so it will load much faster?

1. Can I call ADT Layout Editor in my java source file, not by XML file "open with" menu ?
2. When I click "add" button in the outline view of ADT Layout Editor , it will show such a list of UI components as "AbsoluteLayout AnalogClock AutoCompleteTextView Button ....." My question is where it gets this list? Can I config this path to get my customized UI components?
In the layout editor in Eclipse, I have created a custom view. For some reason, there are a few methods which cause NoSuchMethodError exceptions in the code. Here is the code in the initializer of the custom view:.............

PICTURE OF THE APP, for reference
On button press, I would like an image to be added to the screen, directly under the spinner and with left alignment. When I press the button again, I want another image to be added to the screen.
So if I pressed the add beer button, a drawable of a beer would appear below the spinner. If I pressed the add beer button again, I want there to be TWO drawables of beers under the spinner, preferably with them being added from the right.
(Also, having them reach their width limit, wrapping around, and starting again on the left, but below a full line, would be AWESOME)
I can't figure out how to do this. I assume adding a ImageView in code to a relative layout (because it needs to be positioned to the right) would be the best route, but if it's possible in xml I'd be more than happy to use that.

View 4 Replies View RelatedI have a custom view that I had to write for a large scrollable image, as the images are larger than the size of the screen. Before, I had tried to do it by putting the image into a ScrollView but that of course didn't work. The view itself is within a RelativeLayout within the activity and at the bottom of the screen I have two buttons that are used for navigation and at the top a TextView with a caption for the activity (the main header is already being used here for instruction). In my below code, I've checked the Hierachy Viewer to confirm all the elements are loaded and in the Activity I can see the TextView, however it overlays the ZN5ScrollView area and below the image I just have a blank area of the size defined rather than my buttons. For the bottom navigation, the Hierachy Viewer is saying the absolute_y of the bottom navigation is 480. I'm wondering if anyone can help with my layout code here to get this working correctly? Bottom navigation is 50px high, ZN5ScrollView is 365px above the navigation, and the TextView takes up the rest of the area at the top
View 4 Replies View RelatedI have a layout xml file with a linear layout. One of the children is again a ViewGroup Relative layout. In my java code i want to change the width of this child Viewgroup for my requirements. I tried this
ViewGroup childViewGroup = (LinearLayout)findViewById(childViewGroup);
LayoutParams l = childViewGroup.getLayoutParams();
l.width = 360;
childViewGroup .setLayoutParams(l);
I couldn't do this because findViewById(childViewGroup) doesn't fetch ViewGroups it does only for Views. Note: I cant define a whole new layout.xml for this minor requirement since it is huge layout file and might cause performance overhead. I wanted to just change the width of the child view group in my java activity code.
scrollable meaning by the user touch he can can go up and down in the layout given this is what i did and the emulator throw an exception null pointer somthing and i have problems figuring out from where it comes ....

View 1 Replies View RelatedI have written a command line interface program in the C language. This kind of programs (as you know) waits for user commands typed in the terminal and reacts on depend of them. In fact, the program implements a callback function which parses the command and invokes the appropriate function in order to respond to the user.Now, I have to make a Java GUI (Graphical user interface) for the desktop (Ubuntu) version of this program and then port the same program to the Android Platform (of course the GUI will respect Android framework), so I'm looking for the best way to do it.I have heard about JNI and JNA and I don't known which one will be the best for me. By the way what are the main differences between JNI and JNA.

View 5 Replies View Relatedis it possible to make an entire linear layout scrollable when it needs to be? (when all of the elements in the layout don't fit on the main screen)?I know it is doable with views, etc.but is there a way to incorporate everything on the layout to be scrollable at the same time?Maybe scrollable is not the right term. basically - if one of the elements (a button in this case) doesn't entirely make it onto the main screen of the phone and I need to slide a finger down to access it if that makes sense.

View 1 Replies View RelatedJust something I have been thinking about. It is possible to create an android layout with just a TextView widget and no Layout code (e.g: inearLayout, ScrollLayout), but if I try to add anything else to the XML file all sorts of errors start popping up. Is it possible to create a Layout with just widgets?
Also, if it is, how?
