Android : Add An Array Of Buttons To A GridView In An Application

Apr 21, 2009

I have an application that will have 5-15 buttons depending on what is available from a backend. How do I define the proper GridView layout files to include an array of buttons that will each have different text and other attributes? Each button will essentially add an item to a cart, so the onClick code will be the same except for the item it adds to the cart.

How can I define an array so I can add a variable number of buttons, but still reference each of them by a unique ID? I've seen examples of the arrays.xml, but they have created an array of strings that are pre-set. I need a way to create an object and not have the text defined in the layout or arrays xml file.

Update - Added info about adding to a GridView

I want to add this to a GridView, so calling the addView method results in an UnsupportedOperationException. I can do the following:

CODE:.........

But that doesn't layout the buttons in a grid like I would like. Can this be done in a GridView?

How To Put Mysql Data In Array

Sep 4, 2012

I wanted to fetch the title of an image which is saved in a mysql Db, I found out that you have to do this through Json, right now I am having a .php file:

PHP Code:

<?php
mysql_connect("localhost","xx","xx");
mysql_select_db("xx");
$q=mysql_query("SELECT title FROM field_title");

[Code]...

It outputs as follows:

Code:

[{"title":"titleone"},{"title":"titletwo"},{"title":"titlethree"}]

But now I am stuck, I want to put these titles in a simple arraylist but i don't know how to make the connection between the outputted data and the arraylist itself.

Code:

ArrayList<String> list = new ArrayList<String>();
for (??) {
list.add(string);
}

Is it possible to do this on an easy way?

Android :: Custom Grid View With Array Adapter Out Of Sync With Backing Data

Oct 28, 2010

I'm have a custom GridView Array Adapter. The problem for me is that when the grid list gets large enough to scroll off the screen the gridview and arraylist get out of sync. For instance in my case I have code that checks if an actor is of type director the text color should be red. if you scroll up and down my list enough times all the actors text in my gridview will become red. The thing is that the Gridview appearance actually looks fine its the backing data. Here is the complete class. In the code you can see where I tried to override getItem and getItemId but that didn't fix anything. Code...

Android :: Converting Byte Rgb_565 Array Into Argb Or Rgb Array

Jan 12, 2010

I have Picture data in byte rgb_565 array, and I want convert it in a productive way into argb array. Right now I have found only one (little slow) way to do this: Bitmap mPhotoPicture = BitmapFactory.decodeByteArray(imageData, 0 , imageData.length);

where imageData is my byte[] array in rgb_565, and then: int pixels[] = new int[CameraView.PICTURE_HEIGHT*CameraView.PICTURE_WIDTH]; mPhotoPicture.getPixels(pixels, 0,PICTURE_WIDTH, 0, 0, PICTURE_WIDTH, PICTURE_HEIGHT);

The point is I believe creating a Bitmap object is exacting and not necessary in this case. Is there any other faster way to convert rgb_565 array into argb array? I need this because making image processing on rgb_565 array seems to be a little annoying. Or maybe it is not so hard?

Android :: Converting Short Array To Byte Array

Feb 16, 2010

I am trying to make an application that would be able to send the user's voice over the network using RTP. I am using the ported stack from hsc (JLIBRTP) and I am able to record user's voice in a saperate thread. the problem is that jlibrtp uses has a class named RTPSession that is responsible for the session and has the sendData method that takes a byte [] as argument and the AudioFormat class I am using to record user's voice is in AudioFormat.ENCODING_PCM_16BIT wich is short. I have tried using 8bit audioformat but I get an illigalargument exception in my htc magic and in my emulator. So is there any way I can convert the short [] to byte [] ? would that be acceptable in order of voice quality?, is the above error a known bug for htc magic or the platform doesn't support 8bit audio format?

Android :: Navigating An Array - String Array

Oct 12, 2010

I'm new to android developing but right now I'm working on an application that displays Random Facts. Since I don't want it to be in a random order, I would like to have them in a list. I would like to order through them one by one and show them using TextView.

Resources res = getResources();
myString = res.getStringArray(R.array.FactsArray);

That's what I have so far. If I'm right, that just establishes the array so I can be able to use it later. What I had before was rgenerator which chose a random string from the array and displayed it when I clicked a button.

CODE:................

But Like I said, I would like to just order through them one by one when a button is clicked.

Android :: How Can I Fill In Form On Web Page?

Aug 29, 2010

How would you fill in a form on a webpage (not under my control) in an Android program?I want to write a little android program to automate interacting with a website that someone else has written and I can't change. It has no published API.It is step 4 I'd like the help with. If I wasn't using Android I'd use a library library like libcurl (for python) or apache httpclient (for normal java), or I'd do some DOM interaction with a webbrowser. What would you recommend doing for android? Is there something built into the standard libraries you'd recommend?I'm a pretty experienced Java programmer but all I've written in Android is hello world, if that affects your answer.

Android :: ScrollView Always Fill Dialog

May 3, 2009

Pulling my hair out on this one. I want a dialog that contains a ScrollView with an embedded TextView that will contain what could be a couple of pages of text. Below the ScrollView I want a close button. Everything I try that doesn't involve directly setting the height of the ScrollView results in the ScrollView filling the dialog and the button being invisible because it has been pushed off the bottom. I've tried about every combination I can think of for layout_height and layout_weight of both the ScrollView and the Button but always get the same result.

Android :: Fill Layout With Buttons?

Mar 13, 2010

I want there to be buttons at the bottom of the screen, but if the screen size is larger, more buttons would be added.

For example, at a small screen size, there might be 4-5 buttons at the bottom, but if you ran it on a tablet or something similar, there would be maybe 20 buttons.

It can't scroll either, it just has to dynamically fill the layout with buttons.

Android :: Textview Fill Parent ?

Jul 15, 2010

I have a simple ExpandalbeList. For the group header view, I'm using a simple TextView, I am setting the background of the text to a drawable. I have the textview parameters set to FILL_PARENT, but the background of the TextView only covers the width of the text. I realize that I can put this all inside of a Linear Layout, but that just seems like a waste. isn't there a way to make the bounds of the text view stretch to the edge of the listview?
