How to support searchItem.setOnActionExpandListener in API level 8+?

Question

I am using ActionBarActivity ,How to support searchItem.setOnActionExpandListener in API level 8+ ? It says that minimum API level 14 is required for this.

Below is the my code, Currently I’m suppressing the error and allowing the code execution only if the API is >=14 .

@SuppressLint("NewApi")
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.action_bar_home_screen, menu);
    searchItem = menu.findItem(R.id.action_search);
    SearchView searchView = (SearchView) MenuItemCompat
                .getActionView(searchItem);

        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.ICE_CREAM_SANDWICH) {
            searchItem.setOnActionExpandListener(new OnActionExpandListener() {

                @Override
                public boolean onMenuItemActionExpand(MenuItem item) {
                    hideProgressBar();
                    return true;
                }

                @Override
                public boolean onMenuItemActionCollapse(MenuItem item) {
                    showProgressBar();
                    selectItem(lastSelectedItemPosition);
                    return true;
                }
            });
        }
}

Answer 1

Use MenuItemCompat.setOnActionExpandListener, which is the backport of OnActionExpandedListener.

Answer 2

You can add ViewTreeObserver to track the visibility state of android.support.v7.appcompat.R.id.search_edit_frame. You can check my answer here: https://stackoverflow.com/a/28762632/1633609

This is the copy of my solution from the other question:

I found that MenuItemCompat.setOnActionExpandListener(...) is not working if you don't pass:

    searchItem
            .setShowAsAction(MenuItemCompat.SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW
                    | MenuItemCompat.SHOW_AS_ACTION_ALWAYS);

But this is changing the SearchView and is replacing the DrawerToggle with back arrow.

I wanted to keep the original views and still track the Expanded/Collapsed state and use supported Search View.

Solution:

When android.support.v7.widget.SearchView is changing the view state the LinearLayout view's, with id android.support.v7.appcompat.R.id.search_edit_frame, visibility value is being changed from View.VISIBLE to View.GONE and opposite. So I add ViewTreeObserver to track the visibility change of the search edit frame.

menu_search.xml:

<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto" >

<item
    android:id="@+id/action_search"
    android:icon="@android:drawable/ic_menu_search"
    android:title="@string/search"
    app:actionViewClass="android.support.v7.widget.SearchView"
    app:showAsAction="always"/>

</menu>

In the activity:

import android.support.v4.view.MenuItemCompat;
import android.support.v7.widget.SearchView;
import android.view.Menu;
import android.view.MenuItem;

..........

private View mSearchEditFrame;

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.menu_search, menu);
    MenuItem searchItem = (MenuItem) menu.findItem(R.id.action_search);

    SearchView searchView = (SearchView) MenuItemCompat
            .getActionView(searchItem);
    searchView.setSubmitButtonEnabled(false);
    mSearchEditFrame = searchView
            .findViewById(android.support.v7.appcompat.R.id.search_edit_frame);

    ViewTreeObserver vto = mSearchEditFrame.getViewTreeObserver();
    vto.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
        int oldVisibility = -1;

        @Override
        public void onGlobalLayout() {

            int currentVisibility = mSearchEditFrame.getVisibility();

            if (currentVisibility != oldVisibility) {
                if (currentVisibility == View.VISIBLE) {
                    Log.v(TAG, "EXPANDED");
                } else {
                    Log.v(TAG, "COLLAPSED");
                }

                oldVisibility = currentVisibility;
            }

        }
    });

    return super.onCreateOptionsMenu(menu);
}

You can't do it, the MenuItem.OnActionExpandListener interface itself is available from API level 14 too. If your question related to searching: http://developer.android.com/guide/topics/search/search-dialog.html
