Question

Okay,I’ve been following this tutorial http://coenraets.org/blog/android-samples/androidtutorial/
Basically it gives me exactly what i need for my app

ONLY , I need the search button (or query) to be autoclicked…

I want the user to open the app and see the list already queried

also I have integrated this tutorial into a Tab application, so keep that in mind…

Please any help would be amazing!!! thank you a lot for taking time out of your lives to help me with this stupid thing

I’m a complete noob , I’m learning as I go

Thanka a lot again!

I think the best way to achieve ‘autoclicking’ would be through the textwatcher-interface:

http://developer.android.com/reference/android/text/TextWatcher.html

Like this:

EditText.addTextChangedListener(...)

afterTextChanged(Editable s)
{
//Make your query here using s.getText().toString
//as your WHERE-Clause
}

I would advise you, to debug while using the TextWatcher just to understand how it works 😉
You should also consider that this method could use up a lot of memory, since you query your database with every letter that is typed. You could count the letters typed though, in

onTextChanged(CharSequence s, int start, int before, int count)

and setting a boolean value to true, when the user has typed more then 2 letters and start querying your DB then to avoid too much memory usage.

Edit:

This is the original search-Method:

public void search(View view) {
        // || is the concatenation operation in SQLite
                cursor = db.rawQuery("SELECT _id, firstName, lastName, title FROM employee WHERE firstName || ' ' || lastName LIKE ?", 
                                                new String[]{"%" + searchText.getText().toString() + "%"});
                adapter = new SimpleCursorAdapter(
                                this, 
                                R.layout.employee_list_item, 
                                cursor, 
                                new String[] {"firstName", "lastName", "title"}, 
                                new int[] {R.id.firstName, R.id.lastName, R.id.title});
                employeeList.setAdapter(adapter);
    }

Now try it like this:

searchText.addTextChangedListener(new TextWatcher() {

@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
} 
@Override
afterTextChanged(Editable s){
            // || is the concatenation operation in SQLite
                    cursor = db.rawQuery("SELECT _id, firstName, lastName, title FROM employee WHERE firstName || ' ' || lastName LIKE ?", 
                                                    new String[]{"%" + s.getText().toString() + "%"});
                    adapter = new SimpleCursorAdapter(
                                    this, 
                                    R.layout.employee_list_item, 
                                    cursor, 
                                    new String[] {"firstName", "lastName", "title"}, 
                                    new int[] {R.id.firstName, R.id.lastName, R.id.title});
                    employeeList.setAdapter(adapter);
      }
});

There are some blanks in the code which you have to fill in by yourself. But that’s the basic idea behind my first post.
