Android ActionBar: collapsible SearchView with action button

Question

How to build ActionBar with collapsible search view with single action item visible, when search view is expanded? To be more descriptive, this is what I need:

Answer 1

Just a change menu xml. showaction prefix to your app name

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

<item
    android:id="@+id/menu_search"
    android:actionLayout="@layout/actionbar_search"
    android:icon="@drawable/action_search"
    app:showAsAction="always|collapseActionView"
    android:title="@string/search"
/>

</menu>

Answer 2

After considering the suggestions from comments, many googling and testing succeeded in obtaining the desired effect. I'm not proud of this solution but it works, it's not too complicated and should be enough for this case.

In resume what I did:

1. Placed SearchView with custom "add item" button in customView of ActionBar.
2. Removed collapseActionView and android:actionLayout from search item in menu.xml
3. Collapsing/expanding SearchView programmatically.

Some code to better understand what I did. Maybe this can be useful for someone.

menu.xml

<item
    android:id="@+id/menu_search"
    android:icon="@drawable/action_search"
    android:showAsAction="always"
    android:title="@string/search" />

// ... other menu items

actionbar_search.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="right"
    android:orientation="horizontal">

    <com.actionbarsherlock.widget.SearchView
        android:id="@+id/search_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:iconifiedByDefault="false"
        android:queryHint="@string/search_hint"
        android:visibility="invisible" />

    <ImageButton
        android:id="@+id/add_item"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        style="@style/Widget.Sherlock.ActionButton"
        android:src="@drawable/content_new"
        android:title="@string/add_item" />

</LinearLayout>

MainActivity.java

@Override
public void onCreate(Bundle savedInstanceState) {
    // ...
    actionBar.setCustomView(R.layout.actionbar_search);
    actionBarCustomView = ab.getCustomView();
    searchView = ((SearchView) actionBarCustomView.findViewById(R.id.search_view));
    searchView.setOnCloseListener(new SearchView.OnCloseListener() {
        @Override
        public boolean onClose() {
            searchView.setVisibility(View.INVISIBLE);
            return false;
        }
    });
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        // ...
        case R.id.menu_search:
            if (searchView.getVisibility() == View.VISIBLE) {
                searchView.setIconified(true);
                searchView.setVisibility(View.INVISIBLE);
            } else {
                searchView.setMaxWidth(abCustomView.getWidth() - addButton.getWidth());
                searchView.setVisibility(View.VISIBLE);
                searchView.setIconified(false);
            }
            break;
        // ...
    }
    return true;
}

@Override
public void onBackPressed() {

    if (searchView.getVisibility() == View.VISIBLE) {
        searchView.setIconified(true);
        searchView.setVisibility(View.INVISIBLE);
        return;
    }

    // ...
}

Answer 3

You can do it only using yourmenu.xml.

Set your other menu icon to always show as an action. Your menu.xml should look like this:

<item
    android:id="@+id/menu_search"
    android:actionLayout="@layout/actionbar_search"
    android:icon="@drawable/action_search"
    android:showAsAction="always|collapseActionView"
    android:title="@string/search"
/>
<item
    android:id="@+id/your_other_menu_id"
    android:showAsAction="always"
    android:icon="@android:drawable/your_other_menu_ic"
 />

Answer 4

Simply you can do it like this

@Override
public boolean onCreateOptionsMenu(Menu menu) {
     getMenuInflater().inflate(R.menu.main, menu);
     MenuItem searchItem = menu.findItem(R.id.action_search);
     searchView = (SearchView) MenuItemCompat.getActionView(searchItem);
     searchView.setIconified(true); //to be opened collapsed
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch(item.getItemId()){

        case R.id.action_search:
            searchView.setIconified(false);// to Expand the SearchView when clicked
            return true;
    }    
    return false;
}

And at search item in menu.xml make

showAsAction="always"

Note: I am using android.support.v7.widget.SearchView but in your case it doesn't matter
