I want to make the first suggested line for every AutoCompleteTextView be what the user has currently typed, similar to how google search bar works in smartphones. How can this be achieved?
you have to store the value that user typed in sqlite or shared preferences first.
Then you can filter the value based on user's new search...
Take a look at this link: it uses a web service to load data

This is my application require :
- Get data from a server (JSON)
- Show all data report like image above. Data will display as multi page ( do not scroll), use next and previous button to switch
See how I want:
I can get data from server and show data as listview. But I have some problem and need help.
1. How to display data like image I attached. I found some way but seem it is not good
2. How to display data as multi page. I do not know exactly how much data because it depend data on Server, i have to show all data on server. Pages should auto generate depend on data.
Thanks you.
Simplest way to do it would be to create three datasets (let's say arraylists) and keep previous page data in one and current and future in the next one.
Then put an onClickListener that changes the data in listviews and then notify adapter using .notifyDatasetChanged().
This is not an default Android Behavior, So Please do not follow this design. Better to use Load More Functionality :)
You can refer links for that.

I'm closing in on the ending stages of my application and ran into an unfamiliar problem. I was able to get a google search bar implemented into my application, however the search bar itself is not needed. When the user makes a selection from pre-selected items listed, I need it to send to google search engine without actually having the search bar on the application. Can anyone give me direction on this matter? Thanks you for your help
Use can just define the url like this, where X is the search.
https://www.google.se/search?q=X
You can just search directly via google REST API.
using something like this:
GET https://www.googleapis.com/customsearch/v1?key=INSERT_YOUR_API_KEY&cx=017576662512468239146:omuauf_lfve&q=lectures
heres more information:
https://developers.google.com/custom-search/json-api/v1/using_rest
Just attach whatever it is you want the user to get search results for to the end of https://www.google.com/#q=
So if you want them to search for "butts", it'd be https://www.google.com/#q=butts
Yes! you can use EditText in your activity , then you can implements as google search bar , it is all possible by using Implicit Intent
In MainActivity :
Intent intent = new Intent(Intent.ACTION_WEB_SEARCH);String urlString= editTextID.getText().toString();
intent.putExtra(SearchManager.QUERY, urkString);
startActivity(intent);
i hope its helpful for everyone!!!!
I've one seen on an application for iPhone an interesting idea which consists of showing a list of options when we click on an area for text edition. For example, imagine I have a field called "City" (EditText) which I am suposed to enter the name of the city. When clicking on the EditText, a list automatically shows up with a few city suggestions (e.g. defined by the programmer) which can be selected. If the user doesn't like the suggestions, he writes the city himself and this city can be saved for this list for future.
I want to programme this on my App for android. I need that, when clicking on the EditText for introducing the data, a list automatically shows up with some suggestions defined by me (Programmer). However, I don't know how this can be done. I've googled but maybe it's hard to find the correct keywords to find a similar topic.
The idea is that the user should use the names already written in the list in 90% of the time and just write himself the new ones when it's necessary. Something like a dropdown list but with possibility of writing new stuff instantly without specific option.
How can this be achieved?

Best of luck
You can consider focus changed listener for Edittext,
when focus is gained you can show a context menu to choose data from.
In my app, i have you put in some information through some edit text. Then you hit this button and it starts another activity that does some calculations and then displays results through text views. Well i want to be able to save all of those text views, and then open them up later. On the home screen i have a load button. When you click it, I want to be able to see the stuff I've saved and be able to open it by clicking on it. I'm new to android, so I'm having a hard time figuring this out. How should I go about doing this?
Use SharedPreferences...Check out..

this will help.
I see two questions in your question. The first is how to pass data from one Android activity to another.
The best way to do that is by using the putExtra method of the Intent class and then the getExtras method to extract the data in the receiving activity. Please see this SO quest and answers for more details.
For your second question, how to save data that can be recalled at a later by the main activity, you can use the SharedPreferences APIs. See this web page for more information on that. Basically the shared preferences APIs allow you to save key-value pairs of information which in your case can be field names (keys) and their associated values. For this you would want private preferences and pick a unique name for this preference file.
I am trying to implement a text box that, when the user types something, it asynchronously expands a drop-down menu that contains suggestions, much like how the Google search bar shows predictive search queries. In other words, combining an EditText with a Spinner in the sense that the user types something and it presents a list of selectable options right below it. Does such a class exist in the Android library?
You can follow this tutorial from android:
