Determine AutoCompleteTextView from onItemClick

Question

Is it possible to determine the originating AutoCompleteTextView from the parameters of the callback onItemClick?

I have the following callback function, which is co

Answer 1

Based on @talklesscodemore answer, I solved it this way (I had 2 AutoCompleteTextView's, you have to adapt the following if there are more):

AutoCompleteTextView firstDropdown;
AutoCompleteTextView secondDropdown;

...

@Override
public void onItemClick(AdapterView<?> adapterView, View view, int position, long id) {
    if (isAdapterViewFromFirstDropdown(adapterView)) {
       // Code specific for 1st ACTV
    } else {
       // Code specific for 2nd ACTV
    }
}

private boolean isAdapterViewFromFirstDropdown(AdapterView<?> adapterView) {
    return adapterView.getAdapter().equals(firstDropdown.getAdapter());
}

Answer 2

I use a simpler version of yonoyjoy's answer. It only passes the AutoCompleteTextView to the constructor.

public class AutoCompleteTextViewClickListener implements AdapterView.OnItemClickListener {
    private AutoCompleteTextView mView;

    public AutoCompleteTextView getView() {
        return mView;
    }

    public AutoCompleteTextViewClickListener(AutoCompleteTextView view) {
        this.mView = view;
    }

    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
    }
}

Then in your Activity, you just override onItemClick() like you would in a normal OnClickListener, but use this.getView() to get your ACTV:

autoCompleteTextView.setOnItemClickListener(new AutoCompleteTextViewClickListener(v){
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        super.onItemClick(parent, view, position, id);
        AutoCompleteTextView v = this.getView();

        //Do stuff.

    }
});

I do not have a positive answer to the question (I think it is not possible). But I use a workaround to reach the same goal (find AutoCompleteTextView from within onItemClick):

I defined the following class, which can be used to modify the onItemClick call to provide the AutoCompleteTextView as second parameter (instead of original View param).

public class AutoCompleteTextViewClickListener implements OnItemClickListener {
       AutoCompleteTextView mAutoComplete;
       OnItemClickListener mOriginalListener;

       public AutoCompleteTextViewClickListener(AutoCompleteTextView acTextView, 
               OnItemClickListener originalListener) {
           mAutoComplete = acTextView;
           mOriginalListener = originalListener;
       }

       public void onItemClick(AdapterView<?> adView, View view, int position,
               long id) {
           mOriginalListener.onItemClick(adView, mAutoComplete, position, id);
       }       
}

This can be used in the following way:

Instead of

myTextView.setOnItemClickListener(myListener);

you'll have to write:

myTextView.setOnItemClickListener(
        new AutoCompleteTextViewClickListener(myTextView, myListener));

Now, whenever onItemClicked is triggered by the TextView, instead of the original view value the reference to the AutoCompleteTextView is available.

If you want to know which currentClickedAutoCompleteTextView between autoCompleteTextView1 and autoCompleteTextView2, just check their adapter ...

public void onItemClick(AdapterView<?> adaptView, View view, int position, long id) {
    AutoCompleteTextView currentClickedAutoCompleteTextView;
    if( adaptView.getAdapter()==autoCompleteTextView1.getAdapter() )
        currentClickedAutoCompleteTextView = autoCompleteTextView1;
    else
        currentClickedAutoCompleteTextView = autoCompleteTextView2;
}
