SherlockActionBar with AutoCompleteTextView and other items

问题

I want to have an action bar with AutoCompleteTextView(Collapsible) as a menuItem along with other menuItems like Delete. I am using SherlockActionBar's library to make it compatible with lower version(like 2.2, 2.3).

My requirement is to display

a searchIcon (for collapsible AutoCompleteTextView) at extreme right of the actionBar and
a delete icon to left of above mentioned searchIcon.

Now when user taps on searchIcon, it should expand itself to cover the entire actionBar (hidinig delete icon).

I had tried wrapping both the iconsearch(for AutoCompleteTextView) and deleteButton in a layout and providing this layout as a view for action bar provided by SherlockActionBar library but it didn't displayed anything.

Then I tried adding iconSearch (with attribute value as collapsible) and deleteButton as individual menu items (shown in the SherlockActionBar Samples) but it just displays actionSearch.

I have no idea how to implement the same using SherlockActionBar library. I have tried to implement the same by following the samples given but couldn't achieve this.

Any help would be appreciated...

Thanks in advance.

First create your xml layout from search (layout_search.xml):

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" >

    <AutoCompleteTextView
        android:id="@+id/edit_search"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="Search" >

        <requestFocus />
    </AutoCompleteTextView>

    <ImageView
        android:id="@+id/img_clear"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="right"
        android:src="@drawable/ic_menu_clear" />

</FrameLayout>

In your menu xml:

<item
    android:id="@+id/menu_search"
    android:icon="@drawable/ic_menu_search"
    android:showAsAction="always|collapseActionView"
    android:title="Search">
</item>

Creating menus:

    @Override
        public boolean onCreateOptionsMenu(Menu menu) {
            getSupportMenuInflater().inflate(R.menuyour_menu, menu);        
            menu.getItem(0).setActionView(R.layout.layout_search);
            AutoCompleteTextView search = (AutoCompleteTextView) mI.getActionView().findViewById(R.id.edit_search); 
            ImageView imgClear = (ImageView) menu.getItem(0).getActionView().findViewById(R.id.img_clear).setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                search.setText("");
            }
        });

            return super.onCreateOptionsMenu(menu);
        }

I think you should use ready-made solution com.actionbarsherlock.widget.SearchView.

menu.xml

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:id="@+id/menu_remove"
        android:icon="@drawable/content_remove"
        android:showAsAction="ifRoom"
        android:title="@string/menu_remove" />
    <item
        android:id="@+id/menu_search"
        android:actionViewClass="com.actionbarsherlock.widget.SearchView"
        android:icon="@drawable/action_search"
        android:showAsAction="always|collapseActionView"
        android:title="@string/search" />
</menu>

MainActivity.java

@Override
public boolean onCreateOptionsMenu(Menu menu) {

    // Inflate the options menu from XML
    MenuInflater inflater = getSupportMenuInflater();
    inflater.inflate(R.menu.main, menu);

    return super.onCreateOptionsMenu(menu);
}

I am done with the required implementation. Thanks to Rafal Galka & andrehsouza. I had to combine both the solutions (provided by Rafal Galka & andrehsouza) to achieve the desired effect.

What I did is, I created a menu.xml with two action items. One of them is a standard action item with normal icon and title and another one is with the custom view. And this custom view is nothing but just a simple AutoCompleteTextView which has been defined under res/layout folder.

So here is my res/menu/menu.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android" >
    <item
        android:id="@+id/menu_xxx"
        android:showAsAction="ifRoom|withText"
        android:icon="@drawable/drawablexxx"
        android:title="@string/xxx"/>

    <item
        android:id="@+id/menu_search"
        android:actionLayout="@layout/collapsibleactionview"
        android:showAsAction="always|collapseActionView"
        android:title="@string/action_search"/>
</menu>

and collapsibleactionview.xml has been defined under res/layout as :

<?xml version="1.0" encoding="utf-8"?>
<AutoCompleteTextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/edittextcollapsible"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:hint="@string/hint search"
    android:imeOptions="actionSearch"
    android:inputType="text" />

Bingo !!!
