I recently created a program that gets medi-large amounts of xml data and converts it into arrays of Strings, then displays the data.The program works great, but it freezes when it is making the arrays (for around 16 seconds depending on the size).Is there any way I can optimize my program (Alternatives to string arrays etc.)

View 2 Replies View RelatedDoes anybody know of a work around for the android xml file string array inability to process string <item>'s that are not legal java variable names If not, is this not a major bug? Why does an item in an array need to generate a reference id anyway? Isn't this redundant?
View 2 Replies View RelatedI simply need to add floatArray1 to floatArray2 storing the result in floatArray2.. no third array. all arrays are one dimensional but are very large. probibly as large as the os will let me get away with. Max i would need is two float arrays with 40,000 floats each. but i could get away with 1/10th that i suppose minimum.Would love to do this in 1/30th or 1/60th of a second but that does not seem possible? Also if the code is JNI,NDK or OpenGL ES thats fine. does android have an assembly language or like machine code i could use somehow?
View 1 Replies View RelatedIm currently developing a system where the user will end up having large arrays( using android). However the JVM memory is at risk of running out, so in order to prevent this I was thinking of creating a temporary database and store the data in there. However, one of the concerns that comes to me is the SDcard limited by read and write. Also another problem that comes to mind is the overhead of such an operation. Can anyone clear up my concerns, as well as also suggest a possibly good alternative to handling large arrays ( in the end these arrays will be uploaded to a website by writing a csv file and uploading it).
View 1 Replies View RelatedI am a newb to Android and Java and want to write a funtion that will display a list based on a varable that I pass to the function. The function is below and the code below creates an array out of a string called type, but what I want to do is pass it a variable string and have it build a list based on that string. So if I wanted the type list I would say list_it("type")But if I try something like getResources().getStringArray (R.array.thelist); it doesn't work.Can someone point me in the right direction? public void list_it(String thelist){String[] types = getResources().getStringArray(R.array.type); ArrayAdapter<String> mAdapter = new ArrayAdapter<String>(this, R.layout.list_item1, types);
setListAdapter(mAdapter);
ListView lv = getListView();
lv.setTextFilterEnabled(true);

View 4 Replies View RelatedIn Android, capturing date from datepicker and storing as string in sqlite. Sorting by date doesn't work because they're strings (unless I'm doing it wrong.I've googled this issue for ~5 days, and it looks like there should be a way to capture the date from the date picker, convert it to a Long, store it in sqlite as a Long, select and sort on the Long date value, then convert the Long back to a "mm/dd/yyyy" string for display. I've tried various combinations of parse statements, Date, FormatDate, etc. with no luck at all.On activity start, get today's date and display it in button which calls the datepicker.Capture new date from datepicker (if one is entered), save it as a long to sqlite.On opening an activity showing a listview of records, select from sqlite with orderby on date (Long), convert Long to "mm/dd/yyyy" string for display in ListView.

View 5 Replies View RelatedI 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.

View 1 Replies View RelatedI am trying to create a information based application, I have 92 subjects, for these subjects I have 92 map locations and maybe as much as 400 url links. Currently I have created a class for each map location and a class for each url link, but this would mean I would have in excess of 500 classes, so what I want to do is split the subjects in four catergories ie. listview of about 23 in four tabs which I have done and create a class that gets the url based on the selection the use makes and do the same for the map locations.Do I need to put these in a xml using the id method and how do you call individual entries, i.e. would I need 500 Android:id is there an easier way?
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. */
Arrays.copyOfRange() is unavailable in Android, so I'm wondering what the preferred method of copying arrays is. Manually over a loop, or System.arraycopy()? Also, what was the reason behind the decision to not include Arrays.* ?
View 2 Replies View RelatedI would like to create a list objects called Product (Listproducts).In the application I first have to create the list List products from XML file and then display the products on the map. One product can be located at several locations.Does anyone know what is the most appropriate way to create the structure (a list or linked list) which is the easiest to iterate through and enables to link the lists? The logic should work the following way:
1. Read each point from the list
2. Check which product belongs to the point
3. Display the product informations on the map
My app has large vertex arrays that are pre-computed before I even build the app for distribution. I'd like to store these in assets (recognizing the size limits of asset files) and read them in with minimal computation. Can I store them in binary, and just read them into an NIO buffer, and then wrap it for GL, or do I have to go through the whole compute intensive (?) process of reading it in, making a byte array, and converting that to an integer (in this case) array?

View 1 Replies View RelatedI am using a simple expandable list that is populated by two arrays ( group array for the groups and a multi dimensional children array for the child). The arrays are built dynamically in the program and some group items have more children than others. So I end up defining the highest number as the array size for the multidimensional child array. After populating the child array, some positions are left null, as there are no values for those group items (explained above). When I associate this with the expandable list adapter, the getChildView method throws a nullpointer exception when it comes across a position in child array that does noto have value. I have two questions:
1. Can I make the base adapter skip the shildview method if the value in that child is null? The current implementation of getchildView method has to return a view and even if I suppress the nullpointer exception, it adds a blank element in the child position in the list.
2. Is there a better way of associated multidimensional arrays that are populated at run time? The current set of examples only use hardcoded string array values. Even the cursor adapters examples use very basic setup.
In terms of efficiency, is it better to use arrays programmatically or through calls to xml files.
I'd prefer to use xmls for organisational reasons, but is there much of a performance hit.

I'm trying to write an array of objects that implement Parcelable into a Parcel using writeParcelableArray.The objects I'm trying to write are defined (as you'd expect) as:public class Arrival implements Parcelable {All the right stuff in here this class compiles and acts fine And I'm trying to write them into a `Parcel' with: @Override public void writeToParcel(Parcel dest, int flags) I completely don't understand this error message. Parcelable is an interface (not a class) so you can't extend it. Anyone have any ideas? UPDATE: I'm having basically the same problem when putting an ArrayList of Parcelables into an Intent:Intent i = new Intent();i.putParcelableArrayListExtra("locations", (ArrayList< Location> ) locations);Yields: The method putParcelableArrayListExtra(String, ArrayList< ? extends Parcelable >) in the type Intent is not applicable for the arguments (String, ArrayList< Location >)This may be because Location was the class I was working on above (that wraps the Arrivals), but I don't think so.
