Android :: Array Imported From A File / Converted From String
Nov 10, 2010
I have a text file that I am pulling from my SD card which contains an array in plain text format. Here are the contents of that file ...

I am trying to import that text file into a String, convert that String to an array, and then load that array into a list adapter. If I try to split up readString or a trimmed result of readString, I get a forced close every time. If I copy the contents of the file into a String and then use that ... everything works as expected. So what is the difference between loading this stuff from a text file, and loading it from an included string? Is it a byte conversion issue? Code...

I just want to read <string-array> resource elements into a String array. I don't want to make a view or anything and mess with adapters - just want to transfer the elements. Is there a built in class for this? Or do I need to treat the resource file as a regular file?

I'm new to android developing but right now I'm working on an application that displays Random Facts. Since I don't want it to be in a random order, I would like to have them in a list. I would like to order through them one by one and show them using TextView.
Resources res = getResources();
myString = res.getStringArray(R.array.FactsArray);
That's what I have so far. If I'm right, that just establishes the array so I can be able to use it later. What I had before was rgenerator which chose a random string from the array and displayed it when I clicked a button.
CODE:................
But Like I said, I would like to just order through them one by one when a button is clicked.

I have preferences where you can enable/disable what items will show up on the menu. There are 17 items. I made a string array in values/arrays.xml with titles for each of these 17 items.
I have preferences.xml which has the layout for my preferences file, and I would like to reference a single item from the string array to use as the title.
In the Android developer reference, I see how I can reference a single string with XML, but now how I can reference a string from an array resource in XML.

I have defined a string array in the resource and access it using:
String arrStrings[] = getResources().getStringArray(R.array.arrayname);
But, how can I get the size of this array?

I have a string-array in my resource file that has a little over 1,000 items in it. When I go to launch the activity that calls an AutoCompleteTextView the app won't load this array it simply backs out of that activity and returns to the previous activity. If I delete a bunch of items in the array it begins to work. How can I make it hold all my items? Is there a max size associated with this?

I've looked around for how to use an ampersand ( '&' ) in an item for a string-array but can't seem to find it. I feel silly for having to ask for something this simple, but does anyone know how to escape it?

I have
ArrayList<String> ids = ArrayList<String>();
What would be the cleanest way to make it Parceleable? Apparently String itself is not parcelable, so Parcel.writeList(ids) is not working.I was thinking to either parcelize ArrayList<Uri> or put array contents into a Bundle.

Im trying to make an activity that has a multiple choice dialog after you push a button. In there you select from a list of things. But these things are received from a web method before the dialog appears. So I create a string array after I receive them inside the onCreate to initialise it there with the correct size. But my dialog method then cant get the array because propably its out of its scope.
My code looks like this:
CODE:............
I cant initialise my array when the class starts because I dont know its size yet. This has to do something with the scopes of my variables and I am pretty confused

I have a string array and was trying to style certain parts of the text with tags like <b>, <i>, ... but it doesn't work.
The array looks like this:
CODE:................
The text is displayed in the textview like this: tTitel.setText(Html.fromHtml(Text[ii]));
I tried it without Html.fromHtml too but this had no effect. The styling tags do work if i use them directly in the code, like: tTitel.setText(Html.fromHtml("blabla<b>blabla</b>");
How to style the text in an array?

Is there a possibility to refer to a string ressource in the arrays.xml?
I have tried: <string-array name="services"> <item>@strings/call</item> </string-array>
which I would normally do in a layout file. But it failed.

I have a pretty simple question, but I am still hammering my brain with finding an elegant solution.
I have a spinner filled with an array defined as xml resource:
<string-array name="distances"> <item>item1</item> <item>item2</item> </string-array>
Whenever I close the application I save the selected string of the spinner in a database. E.g. I save "item1".
On application restart I now want to reload the spinner with the previous selection. Therefore I read "item1" from the db and now have to somehow lookup the position of it and there I am stuck. An additionalproblem is that the array might have changed from the time where the data was saved to the db.

I have the localized strings file that is used in the Iphone app that I work on to port to Android. Are there any tools that go through the file taken from the xcode project and build the xml needed to use the strings in android? This tool should be easy to build but I appreciate any pointers to already working tools.

After several hours of searching for the cause of a Out Of Memory Error, I found a wierd problem with Strings. To keep it simple, trimmed it down to something like this:
ArrayList<String> someStringList = new ArrayList<String>(1000);
for (int i=0; i<1000; i++) {
String someBigString = new String(new char[100000]);
String someSmallString = someBigString.substring(0,1);
someStringList.add(someSmallString);
}

I have a String Array Resource that has about 1000 drug names
<string-array name="index">
<item>Aspirin</item>
<item>Levitra</item>
....
</string-array>
I tried to load this string array into a String[] inside an activity. Using the same syntax provided by Google's java documentation found here.
Resources res = getResources();
String[] drugs = res.getStringArray(R.array.index);
It appears my string-array has too many records and its causing my App to crash (stack-overflow?) When I reduce the string-array resource to about 506 records, the app works again, but adding even 1 more element in the string-array would crash the app. What should I do? I want to code logic to filter and do other things to the list. I do not have a SQL db in the app so I can't do the processing in the DB. Is there a way to iterate through the string-array resource without loading it into a String []? I notice the resource is a pointer. Or is there an alternative data structure or approach that would work?

Here is my Problem :
I want to pass multi dimensional String array between two activities or pages.
I already tried with bundle.putextra like methods. But those allow only one dimensional string array.
I really hope you can help me with example java code on this . Here is my String array, final String[][] arr2={{"1","pavan"},{"2","kumar"}, {"3","kora"}};

I have a program that sends a broadcast Intent that needs an "extra" value.The value is declared as being of type Object[], though I know that the elements are always of type Integer or String.That's part of an API not under my control. What's the most concise and/or efficient way to do the equivalent of the putExtra call below?

I am trying to make an android widget like the Google Voice Widget where users can go through an array of Strings which is retreived from the SQLite database. The problem is using global variables in the widget provider. I need to hold the index of the value they are currently on in order to pass it to the intents which are created when the left or right buttons are created. The variable is always returned as zero though.

I am just trying to display a list from an array that I have in my arrays.xml. When I try to run it in the emulator, I get a force close message. If I define the array in the java file (String[] testArray = "one","two","three","etc";) it works, but when I use "String[] testArray = getResources().getStringArray (R.array.testArray); " it doesnt work.Here is my Java file:package com.xtensivearts.episode.seven;
import android.app.ListActivity;
import android.os.Bundle;
import android.widget.ArrayAdapter;public class Episode7 extends ListActivity { String[] testArray = getResources().getStringArray(R.array.testArray); /** Called when the activity is first created. */

How do I save the contents of an array to a file and then read it again later? I have a small amount of data that will need to be stored and since I have no idea where to start on using a SQLite database, I think this will work a lot better.
