Difference between MultiAutoCompleteTextView and AutoCompleteTextView

Can someone explain the difference between MultiAutoCompleteTextView and AutoCompleteTextView?

Solution

  • AutocompleteTextView only offers suggestions about the whole sentence and MultiAutoCompleteTextView offers suggestions for every token in the sentence. You can specify what is the delimiter between tokens.

    String[] words=new String[] {
     "word1", "word2", "word3", "word4", "word5"
 };

MultiAutoCompleteTextView macTv = (MultiAutoCompleteTextView) this.findViewById(R.id.mac_tv);
ArrayAdapter<String> aaStr = new ArrayAdapter<String>(this,android.R.layout.dropdown_item,words);
macTv.setAdapter(aaStr);
macTv.setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer() );

    and:

    <MultiAutoCompleteTextView 
android:id="@+id/mac_tv"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:completionThreshold="1"
/>

    with this example the suggestion comes after every comma.
