Android : How Can I View Data From Database Using Textview?
Aug 12, 2010
I'm doing an admin page that can view the users that exist in the system. My idea is to show a list of the users and the details in one page. I heard that using listview is very tedious. Is there any other way that is easy?
Maybe view in textview but I dont know how it works. I must put in a lot of textview on my xml? A simple task that I need to know how to do. I just need to know how to view data's in a page, using any method. Code...
As you can see I tried to put data from my database straight into the array but it can't work; final String[] TEST = c.getString(1);. The error message Type mismatch: cannot convert from String to String[] appeared.

I'm trying to make my horizontal layouts take advantage of the room available.
In an info showing activity I have a 'fact box' followed by a large box of text. I'd like the infobox to float right, similar to the following picture.
Is this possible using the android TextView api?

I have a TextView and I'd like to add a black border along its top and bottom borders. I tried adding android:drawableTop and android:drawableBottom to the TextView, but that only caused the entire view to become black.
CODE:......
Is there a way to easily add a top and bottom border to a View (in particular, a TextView) in Android?

I have a ScrollView, inside of it there is a TextView, and there are two buttons for PageUp and PageDown in the other part of the layout. When I click on PageDown, I want to see the text in the TextView to scroll down one page. How could I do it?

This is going to be a bit lame question. I have the following code:
CODE:.....
I have a TextView in my xml layout file. I'd like to get it and change my text when I click this button.
But I can't get it (the TextView) unless I make it as a value of a static member of this class and pass it to the constructor. I believe I am missing a big point here, so i'd be very thankful if you could explain how this is meant to be done ?

I am developing an application in which the layout is independent of screen resolution.
Now my problem is that in TextView the textview layout does change itself when the resolution of screen changes but the size of text remain same.I want that when the resolution is high, according to that the text size should also adjust itself(i.e. text size should be changed).And similarly when resolution is low the text size should also shrink.But here when i reduce Y-AXIS to an extent the text vanishes.I will really appreciate any answer.

We are using TextView's Ellipsize function to scrolling text in it and there many other controls in our window. We noticed CPU would go up to 50% if text started scrolling. After digging deeper, we found all controls in our layout kept drawing when texts scrolling. We wonder why? And how to avoid all controls redrawing?

I have a Windows web server already set up with a website (unlimited application pools) and I want to be able to access a database on that server via the Android app I'm developing. How can I do this? Can someone point me to a tutorial or give code example of how this cross-platform (Android/Java to ASP.NET/C#) communication can be done? (I'm trying to create a leader board or global scoreboard for my Android game on my server.)

I created the following method for retrieving stored settings from the database:
public String getEntry(long rowIndex){
String value = "";
Cursor c = db.query(DATABASE_TABLE, new String[] {KEY_NAME, VALUE}, KEY_NAME + "=" + rowIndex, null, null, null, null);
int columnIndex = c.getColumnIndex(VALUE);
int rowsCount = c.getCount();
if(rowsCount > 0){
String value = c.getString(columnIndex);
}
return value;
}
On debugging I can see cursor c contains two columns and one row but when it comes to line
String value = c.getString(columnIndex);
it throws the CursorIndexOutOfBoundsException although columnIndex = 1 which should point to a valid entry. Does anyone know what could be wrong here?

I am new on android and building an application which uses webservice to collect user information in XML. I also get path for a small jpeg picture of each user. (Currently there are about 200 users) I am parsing the XML and storing the information in SQLiteDatabase. Pictures are stored as blob and able to retrieve them.
I display names of users on listview with images as well. But is this a good solution for storing pictures in SQLite Database ? or should consider storing it in file system ? Which is suitable in terms of performance , as well as memory and any other pro and cons on Android.
Also like to know which is best performing XML parser for Android ?
My purpose is only to parse xml files which I get through web services and sort out the data to store in storage. And lastly my memory goes off easily when I load all images to display in list view after making thumbnails of each (which is obvious).
Was wondering is there any library/framework/app available which dynamically loads images as and when required (when that list item is on display) something like Gallery program ?

I am experiencing a problem where when the android device wake up from sleep, the Activity would take forever to get redrawn(and have to terminate it most of the time). I am not sure why, but when I comment out the code below where it retrieves an object from the database based on id stored in the bundle, the problem goes away.
Not sure why the db transaction is causing an issue.
secondly, is it better to store the object in bundle instead of storing its id and retrieving it from db in onCreate?
CODE:...............

If I have a bunch of data that is never going to change (eg. an English language dictionary or the rgb values of a couple hundred color names), how do I use an SQLite database to store it? I know a database is faster than loading everything into memory when the app starts, but how do I make the database either the first time the app runs or "before" the apps ever runs?

I am an android application developer. I am developing an application which requires of me to use Sqlite database. I have implemented fetching the data, but i am facing problems when i try to insert data into the Sqlite database. The problem that i am having is that the new data i enter is not fetched, i.e nothing is new is being entered into the database.
this is the method i wrote in Data.java
myDataBase is an object of SQLiteDatabase
public void insertTitle(String Recipe)
ContentValues initialValues = new ContentValues();
initialValues.put(COLUMN_NAME,value);
myDataBase.insert(ZRECIPE, null, initialValues);
}
and i create an object "d" of it in Add.java, where i call the "insertTitle()" method. But nothing is inserted.

I am currently looking in to developing an application for the android platform. I have some information that is stored within the SQLite Database of Android.
What I want to be able to do is to perform a query to the database table and populate a TableLayout with the information from the database table.
I have tried to find this on the Internet but have not had much luck. If anyone can help me to get about doing this would be great.

I am working on some sample programs, where i have to take the value from the user and store it in the database. I have used DroidDraw to create the XML code for UI.For now, I have just started with a textbox. So, I have to take the value from this textbox and store it in a database. I am using SQlite browser to create tables. I read in some forums, that one way of doing this.
1. Copy the db file in the asset folder of the android project and use the AssetManager class. But i am not able to figure out how to use the asset manager class here. Or if I could get some simpler suggestions on how to store the value from user into the database, it would be great.

I am trying to design a sqlite database that will store notes. Each of these notes will have common fields like title, due date, details, priority, and completed.
In addition though, I would like to add data for more specialized notes like price for shopping list items and author/publisher data for books.
I also want to have a few general purpose fields that users can fill with whatever text data they want. How can I design my database table in this case?
I could just have a field for each piece of data for every note, but that would waste a lot of fields and I'd like to have other options and suggestions.
