public class MultiAutoCompleteTextView
extends AutoCompleteTextView

An editable text view, extending AutoCompleteTextView, that can show completion suggestions for the substring of the text where the user is typing instead of necessarily for the entire thing.

You must must provide a MultiAutoCompleteTextView.Tokenizer to distinguish the various substrings.

The following code snippet shows how to create a text view which suggests various countries names while the user is typing:

 public class CountriesActivity extends Activity {
     protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.autocomplete_7);
 
         ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
                 android.R.layout.simple_dropdown_item_1line, COUNTRIES);
         MultiAutoCompleteTextView textView = (MultiAutoCompleteTextView) findViewById(R.id.edit);
         textView.setAdapter(adapter);
         textView.setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer());
     }

     private static final String[] COUNTRIES = new String[] {
         "Belgium", "France", "Italy", "Germany", "Spain"
     };
 }

Method Summary

boolean	enoughToFilter() Instead of filtering whenever the total length of the text exceeds the threshhold, this subclass filters only when the length of the range from MultiAutoCompleteTextView.Tokenizer.findTokenStart(java.lang.CharSequence, int) to TextView.getSelectionEnd() meets or exceeds AutoCompleteTextView.getThreshold().
(package private) void	finishInit() Sets this to be single line; a separate method so MultiAutoCompleteTextView can skip this.
protected void	performFiltering(CharSequence text, int keyCode) Instead of filtering on the entire contents of the edit box, this subclass method filters on the range from MultiAutoCompleteTextView.Tokenizer.findTokenStart(java.lang.CharSequence, int) to TextView.getSelectionEnd() if the length of that range meets or exceeds AutoCompleteTextView.getThreshold().
protected void	performFiltering(CharSequence text, int start, int end, int keyCode) Starts filtering the content of the drop down list.
void	performValidation() Instead of validating the entire text, this subclass method validates each token of the text individually.
protected void	replaceText(CharSequence text) Performs the text completion by replacing the range from MultiAutoCompleteTextView.Tokenizer.findTokenStart(java.lang.CharSequence, int) to TextView.getSelectionEnd() by the the result of passing text through MultiAutoCompleteTextView.Tokenizer.terminateToken(java.lang.CharSequence).
void	setTokenizer(MultiAutoCompleteTextView.Tokenizer t) Sets the Tokenizer that will be used to determine the relevant range of the text where the user is typing.

Method Detail

finishInit

void finishInit()

Description copied from class: AutoCompleteTextView

Sets this to be single line; a separate method so MultiAutoCompleteTextView can skip this.

Overrides:

finishInit in class AutoCompleteTextView

setTokenizer

public void setTokenizer(MultiAutoCompleteTextView.Tokenizer t)

Sets the Tokenizer that will be used to determine the relevant range of the text where the user is typing.

performFiltering

protected void performFiltering(CharSequence text,
                                int keyCode)

Instead of filtering on the entire contents of the edit box, this subclass method filters on the range from MultiAutoCompleteTextView.Tokenizer.findTokenStart(java.lang.CharSequence, int) to TextView.getSelectionEnd() if the length of that range meets or exceeds AutoCompleteTextView.getThreshold().

Overrides:

performFiltering in class AutoCompleteTextView

Parameters:

text - the filtering pattern

keyCode - the last character inserted in the edit box

enoughToFilter

public boolean enoughToFilter()

Instead of filtering whenever the total length of the text exceeds the threshhold, this subclass filters only when the length of the range from MultiAutoCompleteTextView.Tokenizer.findTokenStart(java.lang.CharSequence, int) to TextView.getSelectionEnd() meets or exceeds AutoCompleteTextView.getThreshold().

Overrides:

enoughToFilter in class AutoCompleteTextView

performValidation

public void performValidation()

Instead of validating the entire text, this subclass method validates each token of the text individually. Empty tokens are removed.

Overrides:

performValidation in class AutoCompleteTextView

performFiltering

protected void performFiltering(CharSequence text,
                                int start,
                                int end,
                                int keyCode)

Starts filtering the content of the drop down list. The filtering pattern is the specified range of text from the edit box. Subclasses may override this method to filter with a different pattern, for instance a smaller substring of text.

replaceText

protected void replaceText(CharSequence text)

Performs the text completion by replacing the range from MultiAutoCompleteTextView.Tokenizer.findTokenStart(java.lang.CharSequence, int) to TextView.getSelectionEnd() by the the result of passing text through MultiAutoCompleteTextView.Tokenizer.terminateToken(java.lang.CharSequence). In addition, the replaced region will be marked as an AutoText substition so that if the user immediately presses DEL, the completion will be undone. Subclasses may override this method to do some different insertion of the content into the edit box.

Overrides:

replaceText in class AutoCompleteTextView

Parameters:

text - the selected suggestion in the drop down list
