Android :: Best Way To Implement An Activity That Lists Recipes

Feb 15, 2010

I'm working on my first Android app, and would appreciate any guidance to make sure I'm doing this the best way. Basically I want an Activity to list recipes. Eventually I'll have another Activity to display an individual recipe selected from the list, but I'm not worrying about that yet.

The list of recipes should show each recipe's title, description, rating, and date added. For each recipe in the list I'd like the title on the top left of the list entry, rating on the top right, description on the bottom left, and date added on the bottom right. I may want to add photo, icons representing properties of the recipe (e.g. vegetarian), etc. The makes me think that each item in the list should be a TableLayout.

With all that in mind, here's what I'm planning to write:

1. Write class RecipesDataAdapter extends BaseAdapter. Override the getView() method to return an instance of TableLayout. Populate each instance of TableLayout with two TableRows, the first row containing cells for title and rating, and the second row containing cells for description and date added. For now I'll just pass the Recipe instances to the adapter in an array.

2. Write class ListRecipesActivity that extends ListActivity. Override the onCreate() method to obtain instances of the Recipe class and call the setListAdapter() method with an instance of the RecipesDataAdapter class.

Notice that all this is done in code without any layout XML files. All the examples of Activities that I've seen use a layout XML file and call setContentView(R.layout.layout_name) but I'm not sure if I need to do that for this, or even how I would do that considering my main Activity is a list of non-trivial things (TableLayout).

Android :: Todo Lists / Task Lists / Evaluations And Reviews

Nov 8, 2009

I'd like to dedicate this thread specifically to the evaluations and feedback for various Todo's, Todo Lists, Tasks, Task Lists, Lists, etc.I'd like to keep this separate from Notepads as I've dedicated that to another thread ( Notepads and Notepad's that sync - Evaluations and Reviews ).Doing a search for Todo's and Tasks on the Android Market comes up with so many results. Rather than downloading and trying out so many, I'd like to know which ToDo's and Task Lists, etc. are recommended.I've been searching for ToDo lists and Astrid is frequently mentioned. Other sync or link to Google Tasks or sync with Google as well.Other ToDo / Task Lists? What are some ToDo / Task you've downloaded and/or experimented with? Please comment on other such productivity Apps. Please indicate if they
1) Offer Multiple Lists
2) Folders
3) Sync
4) Email
5) Offer other unique features

Android :: Scrolling Large Lists Of Cursor-based Adapters Is Faster Than Much Smaller Lists Of In-memory Adapters

Nov 3, 2010

I have an Android app that has both CursorAdapter based ListViews (backed by sqlite) as well as custom BaseAdapter based ListViews which are built on the fly from JSON pulled down from a server.

The data displayed in both is identical - an image and a couple of TextViews. My Cursor-based ListView has 3000 rows, the JSON-based ListView has about 30. However, scrolling down the list is significantly faster for the Cursor-based adapter. For the JSON-based lists, the data is all fetched before the rows are made visible. Images for both types of lists are downloaded on-demand.

I have both ListViews configured identically - both with fastScrollEnabled, scrollingCache and smoothScrollbar set to true.

I'm looking for leads on how to go about trying to figure out what's going on here and to potentially fix it so that the JSON-based ListViews as as fast as the Cursor-based ones.

Android :: Implement An Activity That Uses ExpandableListView

Sep 3, 2010

Im trying to implement an activity that uses ExpandableListView and I have gotten so far but now I have found some strange behavior.

My activity is meant to record food intake as specified by the user. they have a choice of menus (breakfast, lunch and dinner - the outer group) which expand to show their contents.
when a user clicks on an inner menu item a dialog appears asking them for the qty. once they enter a qty and dismiss the dialog the text on the menu item changes to reflect the quantity of that item that has been consumed

The above image shows the list in a closed state.

Below is the list after I have opened the lunch menu and clicked on 'Potato Chips' and indicating a Quantity of 1. As you can see the 'Potato' itemtext has now been changed to reflect the Qty of 1.

The strange part happens now. if I click on 'Lunch' and close the list and then click on it again re-opening it, the 'Qty X 1' text has jumped to another item (Milk)

Each time I open and close the list it jumps back and forth between the two items. Also if I open up other items, such as breakfast, I find that they too have now gotten items with 'Qty X 1' even though I havent clicked them.

The bits of code that are relevant are as such:

The XML for a child element:


The code thats triggered on clicking a child element:


The above code opens a dialog, accepts a value for quantity, appends the list element to reflect this, also saves to database and sets a textview with the selected item and quantity.

Android :: How To Implement Generic Activity - List And Map Activities?

Oct 13, 2010

I want to display the same options menu on all of my application's activities. I created a generic Activity that implements the menu, and all my further activies extend it. The problem: when I need to extend other specific activities, like ListActivity and MapActivity, I can't figure out how to extend the generic activity and add the List or Map behaviour to the new class. To deal with the issue I had to create three different generic activities, each extending Activity, ListActivity and MapActivity.I've tried creating an abstract activity but it doesn't work, I would need to extend two classes at the same time. I could try interfaces but since I can't implement methods, I would have to paste the menu implementation all over the second-level classes, right?

Android :: Implement Touch Events On Activity And Button On Droid?

Apr 23, 2010

I have an Android activity with an ImageButton. I would like to execute some logic when the button is clicked and show a different image for the pressed state, but also receive the touch event on the activity.

By default only the button receives the touch event. If I set the clickable attribute of the button to false then only the activity receives the touch event.

What's the best way to implement the touch event in the activity and the click in the button?

Android :: Lists In Tabs

Jul 12, 2010

I'm new to android development but I have run through various tutorials and am slowly grasping how to develop apps. I modified the Tab Layout tutorial on the android dev website to fit my needs, and now I need to add a list on to each tab I have created. there are a total of seven tabs and each will have it's on specific list. If someone could point me in the right direction to adding a list per tab that would be great. Each tab has it's own class file, would I add the list items as strings in the strings.xml then add code to each tab's class file in order to populate the tab? This was the only thing I have found so far, but it hasn't worked.

Android :: Using The Same ListView For Different Lists

Oct 12, 2010

I have a 3 buttons, say LanguageButton, CountryButton and PinCodeButton. When LanguageButton is pressed, I must display a list of languages. Similarly for CountryButton a list of countries and so on. Only one list is to be displayed at a time.

My question is whether it is better to define a single ListView in my layout or 3 separate ListViews for each list in my layout!

I tried to use a single ListView and set corresponding adapters when different buttons are pressed, i.e in onClick() of languageButton, I give setAdapter(languageArray);

But my doubt arose in implementing the onItemClick() of the list. Because what must be done whenfirst item is clicked in languageList is different from what must be done in countryList. Hence that would add to more code in the java file.

So I am just wondering whether I should simplify my onItemClick() code by defining separate ListViews, or should I simplify my layout and add logic to code?

Android :: Graphically Pleasing Of Lists

May 26, 2010

How to make lists look different than your everyday average black list or more graphically pleasing than you usually see in android apps. I've looked through google code but haven't found too many. I'm looking for different and eye catching lists. I hope this question isn't too generic. Also i'm open to anything, code, examples, blog posts, etc, you name it. I've really struggled with lists and making them look more snazzy. I'm talking more the code level not the graphics or icons used.

Android :: Activities And ListActivities With Button And Lists

Apr 22, 2010

I'm developing a real-time informations about train. The application will connect to a XML plateform that will give the next trains with a station given. I'm a beginner in Android development, and I'm stuck to a class- problem (I think...).

In details, the problem is, when I start the application, the user get a screen with 2 buttons, one of them get the user to a new screen with stations list. But, my problem is, I can't put buttons and lists in the same class. I explain, to get a list on the screen, I have to put : "public class NextTrain extends ListActivity {" but the buttons function doesn't work (the app crashs). By the way, if I put "public class NextTrain extends Activity {" the buttons works but not the list (no crash, but the screen doesn't display anything).

Android :: Trying To Get Document That Lists Permission Levels

Jun 14, 2010

I'm not sure if I completely grasp the Android permissions model. I recently started working on a simple widget to put the phone to sleep. Of course, it always gets a security exception because an ordinary user app isn't allowed to call the Power Manager method 'goToSleep' because it's requires the 'signature' level permission DEVICE_POWER. But I could find nowhere in the docs or on Google that officially says that.Is there some document that lists the permission levels of android platform defined permissions? Or, am I looking at permissions completely wrong?

Android :: Dynamic Lists Of Data In A Layout?

Nov 17, 2010

I want to display contact information in a custom layout. My app lets the user select a contact, then I retrieve key pieces of info on that contact (phone #'s, email addy's, etc). I want to display them to the user so they look grouped logically. Sort of like a series of tables, so phone numbers, then email addys, then organization, etc.

I have a table format that I've been using in a different part of the app where I know the exact number of rows I'm adding and I have defined styles for the rows already. I want to reuse those styles for this data, but android sdk won't allow for you to set the style attribute programmatically.

I could create the tables in code and set all the attributes the same as in my defined styles, but it seems like a lot of extra coding.
