How To Get String Tokenizer Tokens Into ArrayList
Jun 8, 2012
I am in the mid of my application where i have used multidimensional String array
String 1= "A", "10", "XYZ";
String 2 = "B", "20", "PQR";
i am able to split values by using StringTokenizer i.e.
stringTokeniser 1= A
stringTokeniser 2= B
stringTokeniser 1= 10
stringTokeniser 2= 20
stringTokeniser 1= XYZ
stringTokeniser 2= PQR
Now i want to display those values i.e. A, B in one column
10,20 in second and XYZ, PQR in third column respectively.

I'm not very clear about the Intent object and how to use it to pass data between Activities. In my application I have several tabs between which I want to pass ArrayList. Here is a sample code I plan to use, but I'm missing the part where the main activity catches the Intent and passes it to the new activity on start :
1. myTabs.java ==> This is where I think I need to add some code to pass the data between TabOne and TabTwo. For now it is just using the sample code of the TabActivity sample.
CODE:...........
2. TabOne.java ==> I added a piece of code in the onStop procedure to fill in the Intent data with the array I want to pass to TabTwo. Not sure it is the right way to do though.
CODE:...................

I'm working on a android application that will display Strings to the user, and the user then has the option to add one to a favorite list. I have searched and searched and cannot find the proper way of doing this. I did get one open source project, everything worked until the user removed a favorite. The database would clear the row of data, but when a new row is added, it would behave as if the deleted row still had data, leaving blanks in the favorite list.
This is my insert method
public long insertString(String newString)
ContentValues newStringValue = new ContentValues();
newStringValue.put(KEY_STRING, newString);
return db.insert(DATABASE_TABLE, null, newStringValue);
The long returned will always increment even if i use the remove method:
public boolean removeString(long _rowIndex)
return db.delete(DATABASE_TABLE, KEY_ID + "=" + _rowIndex, null) > 0;
If I try to remove the third index, and the user removed a question at the third index, the method returns false, is there a way to completely remove all rows with no data?

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.

In 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.

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 a class that creates a view to gather data via a function getView() that provides a view with an EditText.This class has also has variable answer.When the user chances the EditText I want to store the content of the EditText in answer.If I would use an onKeyListener I fear that the answer will probably get stored before the last letter is entered.Is there a good way to handle this in the getView() function via some other listener?

I have an Android app where I want to check to see if an app name that is installed matches a string passed to the function containing this code.Assuming you called checkInstalledApp('SetCPU'); and the app name on the phone is called the same thing it should return true. However, it never does. I logged the results and it should match up but it does not. Can anyone please enlighten me as to why this doesn't work?

Does anyone have any idea how to find the n-th field (string) in a delimited string where the delimiters (separator) could be either a single char or several chars.and the syntax for user-defined function is FindNthField(string,separator,position)so position 3 would return three,The separator in use would actually be Chr(13).This has to run on Android and so should be efficient.

I have installed Power Strip, and the very first time I was asked to use my preferred home screen, I selected the existing one (using a GS).
What I want to do is to have Power String dock displayed if I do a double click on the home key. I played with the settings but it seems that it doesn't work. Any hint?

I'm writing my own custom view, a keyboard, which I think the ArrayList in the keyboard view is causing the application to quit in the emulator.
public static ArrayList<HexButton> hexButtons = new ArrayList<HexButton>();
The application ran fine when I did
setContentView(myKeyboardView);
But I want to nest my keyboard with a TextView so I'd like to be able to do
setContentView(R.layout.main);

Is there a way to pass an Array List of objects between activities? The myObject implements Parcelable and I'm able to successfully pass the objects around individually, but that means I need to have an exact amount of "myObjects" coded. I want this to dynamically grow/shrink by what the user does with the app. I have seen some posts on the web about doing:
Activity A
ArrayList<myObject> myObjArray = new ArrayList<myObject>();
Then when passing this into the intent I would use:
intent.putParcelableArrayListExtra("myObjArray", myObjArray);
Activity B
ArrayList<myObject> myObjArray = new ArrayList<myObject>();
Bundle extras = getIntent().getExtras(); myObjArray = extras.getParcelableArray("myObjArray");
However, the myObjArray always gets filled with "null". How can I achieve this?

I have an ArrayList<MyList> aList in an activity. I would like to send this data to another activty. Such that,
ArrayList<MyList> aList;
Intent intent = new Intent(); intent.setClass(mainactivity.this, newActivity.class); intent.putExtra("MyList", aList ); startActivity(intent);
On the receiving activity,
Intent i = getIntent(); newList = (ArrayList<MyList>) i.getSerializableExtra("MyList");
But this gets me no where. ERROR! My intention is to share this List between activities.

I was trying to serialize an ArrayList which contains custom objects. I'm serializing it in a Servlet (server side), and deserialize at the client side. (using ObjectOutputStream and ObjectInputStream)
It worked fine, when I work with ArrayList<String>.
But when I tried it with ArrayList<MyObject> I couldn't get any results in the client side, this is the exception:
java.lang.ClassNotFoundException: web.MyObject
Of course I have done this:
public class MyObject implements Serializable { ... }
MyObject contains only String fields.

I am trying to add an object to an arraylist but when I view the results of the array list, it keeps adding the same object over and over to the arraylist. I was wondering what the correct way to implement this would be.
CODE:..............
I have double checked my JSONArray data and made sure they are not duplicates. It seems to keep adding the first object over and over.

package com.example.kupi;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
import android.R.array;

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 wish to display data in the the arraylist in a list view. The arraylist is not a generic list but a object defined by me. I want to display only certain data of the object. Something like, an object of a student, I want to display the student's name only, the student id and the student dob is not required.
