I have created an activity which I need to update with posts made up of a "title" and "description". Earlier a ListView was suggested as an option but I do not know how to add two pieces of text (title and description) to each individual item of the ListView through a String array.
There is a "new post" button on the feed interface that opens a new activity containing 2 TextEdit boxes for adding the title and description.
When "post" is pressed on this second activity I am trying to move the title and description into an array that updates the ListView on the first activity with a new item containing the title and description stated within the TextEdit boxes.
Any help would be greatly greatly appreciated,
Aaron.
The best possible way to this is by using a data base. Android has a built in SQLite data base. You can store in all your data into the data base and query it to get a key/value pair array, which you can pass to your listView adapter class and get the data you need into the list view.

I'm trying to build an app of my website(Just new to programming Java), getting data from my site is all going fine, but now i need to display it. I did some research online for the best way to do it(CustomListView), but coundnt find the solution yet, hope you guys can help me out.
The site i'm making an app of, is just a site where people can post text, or text with a photo.
Getting the text in my listview is going fine, but i also need images to display.
The problem is, how can i tell the Listview that it only contains text, so it wont display any image field, and how can i tell the ListView when there is a photo found by the post,that it also should display that one?
You can use a tag if the post contains an image or not for example if the data is in JSON form just set a tag
[{contains_image:"null"},{contains_image:"yes"}]
Then in your adapter check this tag if the result is a null set visibility gone
You have to create a layout containing a listView.
You have to create an xml lyout corresponding to one row of your list view.
You have to create an adapter which will populate data to insert in your listView
You have to create an onClickListener on your button to add data in your list
If you are using an ArrayAdapter or a CursorAdapter, add the new item you created to the list or the cursor used by your adapter and (notifyDataSetChanged() is automatically called), so your adapter will update the listview

Have at look at this article : http://www.androidhive.info/2014/07/android-custom-listview-with-image-and-text-using-volley/
Once you are go through with above set placeholder image which will be show for the items that do no get dynamic images from your server response.
So I have a custom spinner header, where the user can change the title of names based on selection. What I want to do is if they click on the spinner and change the default, then it only shows the names in the listview from the title of names. Currently I have tried this by reinstantiating my fragment from my tabhost, and if conditions are met it would just remove from list everything that doesnt have what user selected. But this is inefficient and it didn't work as the listview wasn't updated and the condition wasn't even getting called on the new instantiation... Is there any filter way I can do for this? Any ideas or help would be great!
You only need to refresh the ListView not the entire fragment. There are several ways to do this, including providing a different data source to the ListView's adapter. The exact details for how to do this depend on whether you are using an ArrayAdapter or a CursorAdapter.
I have an app that shows news from a RSS feed. There is ListView-1 which loads the news and when you click on an item(news), it shows only the selected news in a seperated xml layout. On the ActionBar for the single news item layout, user can click on Add to Favourites.
I have another activity and layout file and a listview just for Favourites. How can I copy an item from one listview to another?
So, the user can add news from main ListView-1 to another list called ListView-2.
I cannot use intents for sending one list item.
I have been thinking of using SharedPreferences to share an ArrayList, but something else needs to be the solution.
You don't need intents, just separate view and data, keep news in the singleton class, for example NewsManager, and keep one list for all news, one for favourite news, and use favourite list in the ListView2 adapter
Hi All I need your help.
I am currently having problems regarding to Android spinner.
Well, I have two spinners, one for source language and the other for target language. these two spinners values contain language list retrieved from database. For example in database I have list of language:
language_code(en,kr,jp,chinese), description (English,Korean,Japanese,Chinese).
The first spinner will contain all the language description whereas the second one will contain all except the selected one in the 1st spinner.
if the selected item in the 1st spinner is English then the values in 2nd spinner must be only the rest exclude English.
What I want is the user can change the languages any time they want, so when the spinner value is changed, user have to click a button to trigger the change and then using the intent to pass to the same class but with the different spinner value. And what I want is the spinner selected item for source and target are from the previous selection.
I have done with the spinner but I have idea with the dynamic change. Any idea?
Thank you
What is the difference between a listview layout xml and a Listview Java class? I am trying to make it when a user inputs text and presses enter it comes on a set position on the right but when the user receives a reply it would show up on the left side of the list view. Like text messaging on android phones. Does anyone know how i can do this? With a java class or an xml layout? I want animations and dynamic content on the listview as well. Any ideas?
ListActivity provides you all the built-in features of and methods of ListView but only ListView can be added into the whole Activity. By using ListView in xml, you add multiple Views such as Buttons, EditText on the same Activity.
Basically, the xml is for seperating the design (the visuals) from the code (functionality).
Although you can do some funcationality via xml, it's usually better to do it in Java code in your class.
I guess you can create a ListView that will iterate through 2 different list enteries:
The first will show the data (the text in your case) on left and the second entry will show on the right. For each list entery you will create a different xml layout with widgets aligned to the left and right as needed.
