I have a Android Air project written in AS3, when the project starts I am loading the music and loading the XML file to be parsed. In the first frame I call my classes to parse the XML and set the nodes at strings, and to play the audio, these both work fine. Also in my first frame I am declaring some textfields to input the data from the XML file so that when the user enters frame 3 the user is able to see this data from the XML file. This also works fine. The problem I am having is going between frame 4 and back to frame 3, the data in the textfields disapears? I trace the strings from the XML class that are holding the data and these values appear everytime, but going from frame 3 to frame 4 and back to frame 3 wipes out the textfield display? Can anyone point me in the right direction?
thanks

Ok here is some code from frame one where I am declaring the textfields
var name1TextField:TextField = new TextField();
var name2TextField:TextField = new TextField();
var format:TextFormat = new TextFormat();
format.font = "_sans";
format.color = 0xF8FBF8;
format.size = 36;
//set the names format to the textfields
name1TextField.defaultTextFormat = format;
name2TextField.defaultTextFormat = format;
highScore1.addChild(name1TextField);
highScore2.addChild(name2TextField);
Here is the code calling the XML parsing class and setting the text to the nodes
var network:networkScores = new networkScores();
addChild(network);
var timer4:Timer = new Timer(600);
timer4.addEventListener(TimerEvent.TIMER, scoresDis);
timer4.start();
function scoresDis(e:TimerEvent):void
{
name1TextField.text = network.name1;
name2TextField.text = network.name2;
//trace(name1TextField.text);
//trace(name2TextField.text);
name1TextField.width = 230;
name2TextField.width = 230;
timer4.stop();
}
Previously above I had stated that I am calling the audio class and the xml class from the first frame, declaring the text fields and moving on from there. Now I have decided that since this XML file is a list of scores and coded be always changing, I thought it would be good to load and parse this file everytime I enter frame 3. The same thing is still happening, I have my scores display and then when I go to frame 4 and back to frame three, the scores do not display, but when I trace the data from the class, it displays properly.

I've seen this issue happen before with improperly embedded fonts or something, I can't recall exactly. A quick way to test this would be to trace out the .text property of the fields too. This way, when the text isn't visible, if the .text property of the field is still populated then you know you've got a rendering problem.
Do this quick test and post the results, I'll update my answer with more information depending on the outcome.

I am trying to interact with dynamically generated buttons. I want to update text and background color for those player clicked and for those who is near by horizontal or vertical axis at the moment of a click.
What I've tried. I've found an id property of a button in XML which led me to idea that I can make a text key to refer to a programmatically generated button. But when I've tried to assign an id - IDE was expecting a number (Int), not a string. Since buttons form a square array - I decided to encode each button via 4 digit number where first 2 digits stand for a row number and other two stand for a column number. Though when I tried to use findViewById IDE told me that it was expecting a special id data type, not a number.
That's how it looks for now:
for (i in 1..size) {
for (j in 1..size){
val button = Button(this)
button.id = i*100 + j
constraintLayout.addView(button)
}
}
What idea or method could I look at?
If you created it dynamically you can save it in a variable (or an array) for later use.
val myButtons = ArrayList<Button>()
for (i in 1..size) {
for (j in 1..size){
val button = Button(this)
myButtons.add(button)
constraintLayout.addView(button)
}
}
if you have a layout with dynamically created views and you know their order you can get them with getChildAt(index).
Alternatively you can assign ids saved in xml like this.
Hi i am very new to android so i dont know much about it
my question is
How do i store an image and related sound, text somewhere and get it back to display
and how to implement the next button when its pushed the next image with next sound and text is displayed.
thank you !
Keep images (drawables) ids in an array e.g Array array = new Array(){R.id.one, R.id.two};
Keep your sound file in res/raw folder and put sound id as same above in an array.
E.g. Array sound_array = new Array(){R.raw.horn_sound, R.id.peep_sound};
Keep counter and loop over the arrays....
I have a list of 1000 words. I need to load an array with n randomly chosen words from that list (no repeats allowed). What is the best way of going about doing that?
My ideas:
1) Load the words into R.arrays to create a String array. Use collections.shuffle to shuffle the array, then pull the first n entries from it. Right now, I am having memory issues loading the initial array with the 1000 words using this method.
2) Load the words into a text file, read each word into a String array. Use same method to get first n entries.
3) Hard code the input of the words into a String array (I'd use a script to get that output of course). Use same method to get first n entries.
Is there a better way?
If you're mainly worried about memory usage and you're willing to give up computation speed, here's an algorithm that will get you there.
Keep your words in a text file, one word per line, with a fixed amount of characters per word, padding each word with spaces at the end to ensure a fixed word char size, call it s.
Create an array of max size n, call it w
Open a stream reader to the file containing the 1000 words
Get a random number between 1 and 1000, call it k
Seek to position k*s in the file stream and grab the next s characters
Add the word to w if it does not exist in the array yet
If the w array is full (ie. size=n), we're done, otherwise go back to step 3
Let us know how it goes. Happy coding!
I am facing a problem in solving this issue.
I have 30 smiley images. In a grid view I display all the 30 images. So when I select the image based on the position of the image, the corresponding special character will be displayed from SQLite DB. Before I send message to service it is like "hi :)". What I need is to replace the ":)" with the corresponding smiley image in the local folder of my project (eg. R.drawable.facea.png). I am able to fetch the data and replace ":)" with "aaaaa"(example). But when I try to replace the ":)" with Char Sequence (Image), I get 'force close error'. Where am I going wrong?
I have a function to draw image and I get image as in Character Sequence. How can I use the value in this function globally. I also tried to create a global variable and use the CS value globally. But I still get 'force close error.
You need to use a span (specifically an ImageSpan) to be able to embed bitmap in a string. I have written about this on my blog which also covers some common pitfalls.
If you still cannot get it to work I would suggest posting the precise details of what is going wrong: i.e. your code, and the stacktrace that is getting dumped to logcat.
I have a few questions concerning the application I'm designing. I have many different routes I could try in order to get what I wanted, but I thought I would get suggestions instead of doing trial and error.
I'm developing a simple app that has one Game screen (activity) and a main menu to start the game. The game screen will have two buttons, "Next" and "Repeat". Every time "Next" is hit, a new sentence in a different language (with the english translation below it) will appear, audio will pronounce the sentence, and hopefully I can get a highlighter to highlight the part of the sentence being spoken. You can guess what the Repeat button does.
My question is, what do you guys think would be the best way to store these sentences so they can be randomly picked out? I thought about making an array of structures or classes with the English definition, audio, and sentence in each structure. Then using a random iterator to pick one out. However, it would take a long time to do this approach and I wanted to get some ideas before I tried it.
Also, I'm not sure how I would print the sentence and definition on the screen.
Thanks!
Using an array of structs/classes seems like that would be the normal way to go.
Not really sure what you mean by a random iterator, but when picking out random sentences from the array of sentences, you might want to avoid repeats until you've gone through all the elements. To do that, you can make a second array of indices, select one at random from those, use the element that corresponds to that index, and remove that number from the array of indices.
In Java, that would look something like
ArrayList<Sentence> sentences;
ArrayList<Integer> indices;
Random rand;
private void populateIndices() {
for(int i = 0; i < sentences.size(); i++)
indices.add(i);
}
public Sentence getNextSentence() {
if(indices.isEmpty())
populateIndices();
int idx = rand.nextInt(indices.size());
int val = indices.get(idx);
indices.remove(idx);
return sentences.get(val);
}
Quite frankly I would load out of copyright books from Project Gutenberg and randomly pull sentences from them. I would then pass the sentences into Google APIs to translate and pronounce the sentences. Relying on external services is at the very heart of what a connected OS like Android is made for. It would be a much more compelling use of the platform than a canned Rosetta Stone like CD solution and your ability to tap into a broader amount of content would be increased exponentially.
