Development issue/problem:
I want my EditText to work like an AutoComplete, so I write in an XML file.
android:inputType=textAutoComplete|textAutoCorrect
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: https://developer.android.com/training/keyboard-input/style#AutoComplete.
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:
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(R.id.autoCompleteTextView1) ;
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: https://stackoverflow.com/a/37298258/1808829
A piece of code:
The public class AutoSuggestAdapter extends ArrayAdapter
{
@overview
public view getView(int position, View convertView, ViewGroup parent)
{
// handle view here
}
@Override
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.setAdapter(adapter);
autoCompleteTextView1.setThreshold(1);
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!
