I need to develop a task with the concept of Providing points to the Competitors. It must be done Dynamically. So i have chosen the NumberPicker for the Points value. I need to list the Competitors from the Database and it will be in two separate columns such as Id and Name.
While the run time i need to Evaluate and Put Points to them by using NumberPicker with a range of 0-10.
And i need to Get the value from the NumberPicker to the Textview and store the Value in my Database
Please Help me for my Task..
Thanks In Advance

Let I have some number n. It can be equal to any integer number ranged between 2 and 15,for example. And according to this number, I need to show n TextView's(orButtons). I need this concept for creating kind of 4 pic 1 word quiz game. As you know, in this game , if secret word is banana,then app create 6 places for each letter. And my question is what kind of concepts to use in order to solve this problem? My idea for solution was following: creating some view and add to this view a TextView n times. But I don't think that it is right way to do that. Can you tell me what I have to use in order to achieve my goal?
Loads of ways to achieve this:
You couid just create the placeholders you want in an XML Layout, I would of thought EditText with maxLength=1 and then use .setVisibility to show the ones you need depending on question;
You could use a loop to generate the number of elements you want. See
here for code example
How could I make a user Interface like the one with NumberPicker but the data came from the SQLite. Is there a Layout for this?
Like this User Interface
What do they call this Interface?
I'd like to create a view data from SQLite. Some what like
Apple
Banana
*Cake*
Donut
Eclair
Don't recommend using DialogFragment. I wanna do like this
Scrollable List
Unfortunately there is no layout that does that out of the box, so you will have to do a lot of heavy lifting before getting things working. But the easiest way is to use NumberPicker and pass to it the values that you want to display as an array with setDisplayedValues. But you still have to create the connection to the database and query for the cursor that you will have to transform somehow to an ordered array, for which you can then map the values of the NumberPicker to the actual values in the database (told you, not easy...).
There is no easy way out of this, you could also try making your own component or buy one that does this for you.
This is what I've been looking for.

New to android development. I recently finished the lynda.com tutorials, but want to get more involved. I was thinking about doing an app that shows various quotes from movies, but am in need of some guidance. I just want it to have one activity and am going to have a next and previous buttons at the top. How would I create the app that shows quotes in a randomized order and keep the quotes on the same screen?
Thanks for any and all help!
Create an SQL Database and store your strings in the table and display it using list view.
http://www.androidhive.info/2011/11/android-sqlite-database-tutorial/ - tutorial for database.
Your request is essentially just a basic layout question: Create a basic view, lay it out with a text field and two buttons. Create either an array list of strings or an SQLite database (as detailed by user3245033). You will then need to add listeners to both buttons (http://developer.android.com/reference/android/widget/Button.html). The next button should generate a random number that becomes an index into the list or database storing your quotes, the back button should store the previous index value (so that you can go back to the same quote as opposed to a random quote). When you're retrieved your quote, set the text field to that string.
There are many basic examples that demonstrate this type of work. mybringback on YouTube particularly amazing:

I have a button on my home screen that will add an edit text field every time it is pushed (I limited it to 20 for best practice). It is basically a small budgeting app. I want the user to fill in an X amount of dollars in one of the fields. Then, when they are ready, to come back to the app another time and that created EditText is still there filled with the value. I know how to utilize SharedPerfrences to hold the value. I do not, however, know how to hold that newly created EditText field when the user comes back.
I am acutally going to expand and have a button and a datepicker associated with each EditText field so soon click the button will create three objects, not just one. But I want to get one working first and will apply the principle to the others later. Any suggestions?
Sounds like a good candidate for a SQLite database.
For instance, I use a SQLite database to retain and recall the co-ordinates and types of widgets that the user has arranged within my application.
Note that you don't ever want to be trying to store and recall the actual EditText View object itself. In your database you need to devise your own table format that suits the kind of information you need to store. If you simply need to retain the states of a series of EditText fields then this could be as simple as having a table with just one column that contains a string value on each row. To build your UI up again from that database, you'd loop through and create a new instance of EditText, and set the text of each one from the table.
You would have to use Android Parcelable interface, refer to this to know as of how to implement it, refer to this question which I has asked on StackOverflow, it has a good answer.
Is there a way of getting SQLite on Android to use a custom collation routine?
I'm aware of SQLite's C interface to do this, so I guess I could do it by writing C code for building with the NDK, but I'd really prefer a way to do it at a higher level.
I need to arrange things so that the text B-9 is sorted before B-29, for example. The default alphabetical sort gets them the wrong way round.
I am pretty sure that there is no way to do this in Android.
My suggestion would be to have a custom column used for ordering where you insert the value in a modified way that gets sorted as you wish.
In your case you could insert B-9 as B-09 or B-00....09 depending on the max value.
