Android SearchView empty string

Question

I\'m trying to use a SearchView and I got everything to work, except when I want to search an empty string.
The onQueryTextChange does react when I remove the last character

Answer 1

Perhaps it's not suited for your app but you also have the option to use a simple EditText, then add a TextWatcher listener. This way you catch every input even if the user enters an empty string.

Answer 2

I had same issue with SearchView but I did not want to use ActionBarSherlock so I came up with solution which consists of styling your own SearchView as shown in guide http://novoda.com/blog/styling-the-actionbar-searchview/ and setting OnEditorActionListener for EditText( How do I trigger an action when the user has hit enter?) which is part of the SearchView.

final SearchView searchView = (SearchView)findViewById(R.id.search);
int searchPlateId = searchView.getContext().getResources().getIdentifier("android:id/search_src_text", null, null);
EditText searchPlate = (EditText) searchView.findViewById(searchPlateId);
searchPlate.setOnEditorActionListener(new TextView.OnEditorActionListener() {
    @Override
    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {

        if (actionId == EditorInfo.IME_ACTION_SEARCH) {
            //Do something
        }
        return false;

    });
