AutoCompleteTextView侦听器

Question

I'm creating input with drown menu, which fetches data from server with input from user and adds the data to the list.

I got this code:

from_autocompl = (AutoCompleteTextView)rootView.findViewById(R.id.from_autocompl);
        from_autocompl.addTextChangedListener(new TextWatcher() {

            @Override
            public void onTextChanged(CharSequence s, int start, int before, int count) {
                    new JSONParse().execute();
                    if (ImDoneWithJSON == 1)
                    {
                        ArrayAdapter<List_From_JSON> adapter = new ArrayAdapter<List_From_JSON>(
                                this, android.R.layout.simple_list_item_1, data);
                        from_autocompl.setAdapter(adapter);
                        ImDoneWithJSON = 0;
                    }

            }
        });

Now the problem I got is: I need to know which items in dropdown list is clicked.

Usually it is done by using onItemClick , but I already have TextWatch listener added to from_autocompl and android allows by default only one listener and now I want to know how to do it. How to by pass this?

You no need to use textChange Listener Use this, AutoComplete Box have the default property of textwatcher

            public class MainActivity extends Activity {

// private AutoCompleteTextView autoComplete;
 private MultiAutoCompleteTextView multiAutoComplete;
 private ArrayAdapter<String> adapter;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    // get the defined string-array 
    String[] colors = getResources().getStringArray(R.array.colorList);

    adapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,colors);

    //autoComplete = (AutoCompleteTextView) findViewById(R.id.autoComplete);
    multiAutoComplete = (MultiAutoCompleteTextView) findViewById(R.id.multiAutoComplete);

    // set adapter for the auto complete fields
//  autoComplete.setAdapter(adapter);
    multiAutoComplete.setAdapter(adapter);

    // specify the minimum type of characters before drop-down list is shown
    //autoComplete.setThreshold(1);
    multiAutoComplete.setThreshold(2);
    // comma to separate the different colors
    multiAutoComplete.setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer());

    // when the user clicks an item of the drop-down list
    multiAutoComplete.setOnItemClickListener(new OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
                long arg3) {
             Toast.makeText(getBaseContext(), "MultiAutoComplete: " +
                        "you add color "+arg0.getItemAtPosition(arg2),
                        Toast.LENGTH_LONG).show();
        }
    });
}
