Android :: ArrayList Populated With Last Elements Data?
Jul 1, 2010
I am using the Android onTouchEvent to register touch and the associated movement. I then want to iterate a sprite along that path.
I need to store the path traced by the finger for use later on.
The problem is that after the finger is lifted off the screen the ArrayList (pArray) is completely populated with the X & Y position of the ACTION_UP coordinates.
From the Log i can see that it is adding the current X & Y position to the Arraylist while the finger is moving which is great but then the Arraylist gets overwritten by the data in Arraylist.size() - 1...

I am developing some application for android and i have problem.
I push data with button click from another activity with intent to string of first activity, and i put from that string these data to listview by a adapter, and it is all ok, i mean i see on listview that data, but when i want to add new item in listview by click of button of second activity, i mean do again same thing, there is a problem: that data i push by a second button click replaces first button click data, and i want to add that data under first data in another listview row?
here is code of activity where is a listview:
package com.example.kupi;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
import android.R.array;
import android.app.Activity;
[Code] .....

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.

I have an issue with a virtual keyboard.
This Soft Keyboard Covers Data Fields - and can't See what's going on.
I want to use this soft keypad and at the same time it should not become a problem to use data fields.
So how can I manage the data fields in such cases?

I have a child Activity that contains a ListView. This Activity is populated asynchronously from a SQLite cursor. The list items contain a TextView, a RadioButton, and a normal Button. The XML is shown below:
CODE:...............
I have to do some logic to determine which RadioButton is selected by default, and I can't do it until the ListView is already loaded. The problem is that with all the events I have tried so far (onCreate, onPostCreate, onResume, onWindowFocusChanged), the ListView child count is zero. I've also tried using the getView method in the ArrayAdapter class, but that method is called mutliple times and the ListView child count is potentially different every time, leading to unexpected results. Apparently, these events are firing before the ListView has finished being completely populating with its child items.
Is there an event I can listen for, or some other way to determine when the ListView is finished populating and has all of its children accessible to be modified programmatically?

I have a list view with 2 buttons on each row. I am using a cursoradpater to populate the list. I am also using the view holder pattern on newview() bindview().
My questions are: where do i put the clicklisteners for the buttons knowing that the action for the button is different from the action of the list item itself? Do i keep the onListItemClick ?

I'm trying to bind a pre-populated database (.db file) to my application, so that I could use the data right away. I cannot, however, figure out a way to: 1) Store the .db file inside the application. 2) Access the database inside the application.

I got some problem with my database in my Android application. Perhaps, my application is working but let me explain you.
Here are just parts of the code from my app.. i don't want to paste the whole it's not needed.
CODE:....................
So when i try to run my app i get Force close, but when i put manually: dh.insert("test", "ooo");
In the onCreate method in my main activity everything is fine and working. So, the conclusion is that i must put some value for the first time i run the app so it can work properly. I thought maybe to update that row with the new informations that i insert later through some TextView's from the app.

I have a ListView which is embedded in a ScrollView. I populate the rest of the Views in the ScrollView, then populate the ListView. Unfortunately yhe ScrollView doesn't size itself to accomodate the items in the ListView. Am I missing something? Is there a way to get the View to resize itself to accomodate the contents of the ListView?
Here is the View in question :

I have a ListActivity which is being filled via an internal class "OrderAdapter" - while the list is being populated I set various OnClickListeners on the TextView elements which should open the same view with different parameter values per line. My problem I have is that no matter which entry in the list I click I will always get to a view with the same parameter ID (it's always the ID of the last line in the list) - even though the output of the ID varies if I output it to the TextView.
Here is the code of the internal class which populates the list in the ListActivity:
CODE:.............
Any ideas why it always opens the view with the same ID even though the TextView "tvCheatTitle" displays a different value in every line?

ListAdapter adapter=new SimpleCursorAdapter(this,
R.layout.row, constantsCursor,
new String[] {"title", "subtitle", "image"},
new int[] {R.id.value, R.id.title, R.id.icon});
However, the other fields are populated, but the image remains empty.

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.

I'm trying to modify two TextViews in exactly the same way. I thought I can give them same id and with findViewById() and setText() methods change those TextViews in two lines. But it seems only one TextView is changed.Is there a way to do this?Or I have to make different ids for every element, get every element by findViewById() method and set it's text?
