How to make SearchView lose focus and collapse when clicking elsewhere on activity

Well I found out the following solution. I used setOnTouchListener on every view that is not an instance of searchview to collapse the searchview. It worked perfect for me. Following is the code.

public void setupUI(View view) {

    if(!(view instanceof SearchView)) {

        view.setOnTouchListener(new OnTouchListener() {

            public boolean onTouch(View v, MotionEvent event) {
                searchMenuItem.collapseActionView();
                return false;
            }

        });
    }

    //If a layout container, iterate over children and seed recursion.
    if (view instanceof ViewGroup) {

        for (int i = 0; i < ((ViewGroup) view).getChildCount(); i++) {

            View innerView = ((ViewGroup) view).getChildAt(i);

            setupUI(innerView);
        }
    }
}

This is the answer I referred to.

Well, I have another simpler and tidier way of doing this. If you're using search widget as an action view in the toolbar (https://developer.android.com/guide/topics/search/search-dialog#UsingSearchWidget), you might want to make the SearchView lose focus and hide the keyboard when user touches anywhere else on the screen.

Instead of iterating and setting up touch listeners on every view in the hierarchy except the SearhView, you can simply make use of this solution since the SearchView has a AutoCompleteTextView in it.

Step 1: Make the parent view(content view of your activity) clickable and focusable by adding the following attribute

android:clickable="true"   
android:focusableInTouchMode="true"

Step 2: Set OnFocusChangeListener on the SearchView AutoCompleteTextView

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.menu_main, menu);

    final MenuItem search = menu.findItem(R.id.action_search);
    SearchView searchView = (SearchView) search.getActionView();

    // get a reference of the AutoCompleteTextView from the searchView
    AutoCompleteTextView searchSrcText = searchView.findViewById(android.support.v7.appcompat.R.id.search_src_text);
    searchSrcText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            if (!hasFocus) {
                InputMethodManager inputMethodManager = (InputMethodManager) getSystemService(Activity.INPUT_METHOD_SERVICE);
                inputMethodManager.hideSoftInputFromWindow(v.getWindowToken(), 0);
            }
        }
    });
    return super.onCreateOptionsMenu(menu);
}

That's it! Hopefully this is useful for future readers :)
