Development issue/problem:

I want my EditText to work like an AutoComplete, so I write in an XML file.


but it’s not working.

I am working with API v2.2 and my Activity extends MapActivity, there I have a simple EditText and a button called Search. So, if we type a place name in EditText and click the Search button, it means it should go to that place on the map.
So I want EditText to work like AutoComplete.
How can I do that?

How can I solve this problem?

Solution 1:

Just use AutoCompleteTextView instead of the normal EditText.

The Hi-Autocomplete function will be useful.

EDIT: The above link seems to have expired. The new site is here:

Solution 2:

First convert your EditText->AutoCompleteTextView

Next, connect your XML file to AutoCompleteTextView via the ArrayAdapter.

Assuming that the array of XML strings you created is named list_of_countries, you can link it to your AutoCompleteTextView as follows:

String[] countries = getResources().getStringArray(R.array.list_of_countries) ;
ArrayAdapter = new ArrayAdapter(this,android.R.layout.simple_list_item_1,countries) ;
actv.setAdapter(adapter) ;

Solution 3:

I use this code:

android how an EditText work as AutoComplete –

1) In AndroidManifest.xml

2) For xml layouts, use AutoCompleteTextView instead of EditText.

3) Use it in the activity file

private ArrayAdapter getEmailAddressAdapter(Context context) [
Account[] accounts = AccountManager.get(context).getAccounts() ;
String[] addresses = new String [accounts.length] ;
for (int i = 0 ; i (context, android.R.layout.simple_dropdown_item_1line, addresses) ;

4) For creative activities :

AutoCompleteTextView autoCompleteTextView1 = (AutoCompleteTextView) findViewById( ;
autoCompleteTextView1.setAdapter(getEmailAddressAdapter(this) ) ;

Solution 4:

By default, the ArrayAdapter filters only on the first characters. If you also want to see the words that contain the keyword, you must use a custom ArrayAdapter and override the getView and getFilter methods. See the complete solution I provided in another StackOverflow question:

A piece of code:

The public class AutoSuggestAdapter extends ArrayAdapter
public view getView(int position, View convertView, ViewGroup parent)
// handle view here

public Filter getFilter()
// implement filtering here

Solution no. 5:

This code is used to change the settings of MultiAutoCompleteTextView

ArrayAdapter adapter = new ArrayAdapter(this,android.R.layout.simple_list_item_1,codeKeyWords);
MultiAutoCompleteTextView autoCompleteTextView1 = (MultiAutoCompleteTextView) findViewById(R.)).id.autoCompleteTextView1);
autoCompleteTextView1.setTokenizer(new this.CommaTokenizer()) ;

And here is this code to separate words with a space and n characters…. (Why do we need this code? Because Normal multiAutoComplete.setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer()); so, and it separates words into ‘,’ characters, but our code will help you to separate words into ‘ and ‘n’ characters).

* This simple tokenizer can be used for lists of
* items separated by a comma and one or more spaces.
public static class CommaTokenizer implements Tokenizer {
public int findTokenStart(charSequence text, cursor int) {
int i = cursor ;

while (i > 0 && text.charAt(i – 1) != ‘ ‘) {i–;} while (i 0 && text.charAt(i – 1) == ”) {i–;}

if (i > 0 && text.charAt(i – 1) == ‘ ‘) {
return text;
} else {
if (text instance of Spanned) {
SpannableString sp = new SpannableString(text + n);
TextUtils.copySpansFrom((Spanned) text, 0, text.length(),
Object.class, sp, 0);
return sp;
} else {
return text +;

Good luck!
