How can I avoid autocomplete dropdown appearing when text is programmatically set?

I have an AutoCompleteTextView in my layout. I also have an alternative way to select the same items which are present in the AutoCompleteTextView. When the alternative way is selected, I populate the value in the AutoCompleteTextView via:

autoCompleteTextView.setText(valueFromAlternativeSource);

where valueFromAlternativeSource is one of the valid auto complete options. The trouble with this is that the autocomplete dropdown appears when setText is called. Putting the following line after the above doesn't work:

autoCompleteTextView.dismissDropDown();  //Doesn't work.  Why?

Any ideas on why dismiss dropdown isn't working or other ways I could dismiss the dropdown?

This works fine for me and is less complex:

ListAdapter adapter = autoCompleteTextView.getAdapter();
autoCompleteTextView.setAdapter(null);
autoCompleteTextView.setText("whatever");
autoCompleteTextView.setAdapter(adapter);

If you want to support API<17, Subclass AutoCompleteTextview and override setText(text, filter) method

@Override
public void setText(CharSequence text, boolean filter) {
    if(Build.VERSION.SDK_INT>=17) {
        super.setText(text, filter);
    }else{
        if(filter){
            setText(text);
        }else{
            ListAdapter adapter = getAdapter();
            setAdapter(null);
            setText(text);
            if(adapter instanceof ArrayAdapter)
                setAdapter((ArrayAdapter) adapter);
            else
                setAdapter((CursorAdapter) adapter);
            //if you use more types of Adapter you can list them here
        }
    }
}

Then whenever you want to set the text manually call setText(text, false)

autoCompleteTextView.setText(valueFromOtherMeans, filter);

     * @param filter If <code>false</code>, no filtering will be performed
     *        as a result of this call.

Looks like its a problem of the order how messages are processed. My work around looks like this:

//autoCompleteTextView.dismissDropDown();
new Handler().post(new Runnable() {
    public void run() {
        autoCompleteTextView.dismissDropDown();
}});

My solution (but I don't like it, there must be something better):

autoCompleteTextView.setText(valueFromAlternativeSource);
autoCompleteTextView.setDropDownHeight(0);

autoCompleteTextView.setOnKeyListener(new OnKeyListener(){

   @Override
   public boolean onKey(View v, int keyCode, KeyEvent event) {
       autoCompleteTextView.setDropDownHeight(LayoutParams.WRAP_CONTENT);
   }
}
