SearchView's OnCloseListener doesn't work

Question

I\'m trying to add support for the SearchView in the Android 3.0+ ActionBar, but I can\'t get the OnCloseListener to work.

Here\'s my code:

Answer 1

There is no console in Android to log to. Instead, use the android logging framework:

Log.d("Test Tag", "Testing.  1, 2, 3...");

Answer 2

There are two common patterns for SearchView.setOnCloseListener(). This is really true of all listeners, but I'm addressing your question specifically. The first way is to create a listener function and attach it to a member variable, and the second is to make the class implement the interface and have the handler be a member function.

Creating a listener object looks like this:

private SearchView mSearchView;
private final SearchView.OnCloseListener mOnCloseListener = 
    new SearchView.OnCloseListener() {
        public boolean onClose() {
            doStuff();
            return myBooleanResult;
        }
    };
mSearchView.setOnCloseListener(mOnCloseListener);

Implementing listener at class level looks like this:

public class MyClass implements OnCloseListener {
    private SearchView mSearchView;

    public MyClass(...) {
        mSearchView.setOnCloseListener(this);
    }

    @Override
    public boolean onClose() {
        doStuff();
        return false;
    }
}

I have not seen any examples that create the OnCloseListener ad-hoc, as you did in your question.

Answer 3

seems an old thread already, but I thought I got the same problem API 18 in the first beginning. After googled around, found this thread, another hour read the javadoc tried and errored for something I don't pretend fully understand in javadoc, the following work for me now:

searchView.setIconifiedByDefault(true);

   // OnQueryTextListener
   @Override
   public boolean onQueryTextSubmit(String query) {
      Log.d(tag, "onQueryTextSubmit: " + query);
      return true;
   }

   @Override
   public boolean onQueryTextChange(String query) {
      Log.d(tag, "onQueryTextChange: " + query);
      return true;
   }

   // OnCloseListener
   @Override
   public boolean onClose() {
      Log.w(tag, "onClose: ");
      return false;
   }

I played with true/false a bit, that somehow makes the difference, and it works for me now. Hopefully, it could save someone time.

I also meet this problem, and I have no choice but give up "oncloselistener". Instead, you can get your menuItem, then setOnActionExpandListener. Then override unimplents methods.

@Override
public boolean onMenuItemActionExpand(MenuItem item) {
    // TODO Auto-generated method stub
    Log.d("*******","onMenuItemActionExpand");
    return true;
}

@Override
public boolean onMenuItemActionCollapse(MenuItem item) {
    //do what you want to when close the sesarchview
    //remember to return true;
    Log.d("*******","onMenuItemActionCollapse");
    return true;
}

Answer 5

The reason the OnCloseListener is not called is because there is a bug in the Android code -- the listener is only called if you also call setIconifiedByDefault(true).

Answer 6

I encountered this issue while trying to detect the showing/dismissal of the SearchView. I ended up using a different listener and it worked for what I need:

        setOnQueryTextFocusChangeListener { _, hasFocus ->
            if (hasFocus) {
                // SearchView is being shown
            } else {
                // SearchView was dismissed
            }
        }
