I need to have a DialogFragment or similar with a ListView which contains a list of strings. I also need to have some kind of footer or something so I can add more strings to the ListView.
Basically it is a dialog where a user can specify and add endpoints to the app, and clicking on a String of the ListView would make the app connect to that endpoint.
How could I do this? Should I use a ListView with a footer? How could I store the strings in the device?
Thanks a lot in advance!
If you want to store Strings after close your app, you should use SQLite database, there you've got a nice example of use it
SQLite tutorial,
and there you could read how create a DialogFragment with ListView
DialogFragment with ListView.
To put data from database to ListView you should get List<String> someData from your database.
To add new String you could add it to database and refresh all Dialog View, or add it to list using comand someData.add(String string);
Hope I help

Currently I have been stuck in the implementation of the search item json Url logic. I have TextWatcher code but I do not know how to implement to search an item that user input in the EditText.
I want once the user start typing the search will be triggered and search dynamically, and once the user hits on the DONE button on the Keyboard the string in the EditText will be searched automatically
How do I implement this ? Or is there someone with a better idea?
Please provide examples...Thanks in Advance.
It is good if you can save your json data to local storage using mysqlite or you can also use ArrayList for storing your json data.
download all json data on OnCreate() method of activity.
store it to ArrayList.

I am quite new to Android development. I managed to get data saved to SQLite database. Now, what I want is to view these data when I call viewData(). I have viewData() which shows data as a Toast as I made it as a sample. Now I need these data to show on a new activity but the number of data to show is depending on how many data is in the database at the moment, If user saved 10 items then I want all the 10 items to shown up. How can I do it?
What is the best way to show data from SQLite database on an activity. Since I don't know to use ListView, I used TableLayout on the other activity where user feed data.

I am using parse api for my application.I am getting a list of items from the parse and after getting the list I wanted to populate it in the listview which would contain the following things:
ProductName(TextView)
ProductQuantity(EditText)
After getting list user would feed the quantity of every product and this information will be loaded in the new activity for adding extra information and after that it will be submitted to the server back.
I am familiar with lists but confused how can I use edittext in the listview to feed quantity of each product.

Can anybody please help me in adding List of items that is stored in my Java file into My List Activity. I fetch the list items from remote database through my JDBC connection (java.sql). Then I try to store it in different variables in a java file. Finally I want to fetch these items and display it in my list. How do I do it?
Also I would like the list items to be dynamic as in future new items might be added.
My List item will be an array List.
Thanks & Regards,
Sneha
For the listView part you will need to write an adapter that fetches the data from your java file and bind it to each row in the listView.
Read this tutorial for custom list views.
