android:showAsAction="always"
android:actionViewClass="android.widget.SearchView" /></menu>
<pre>

<!--?xml version="1.0" encoding="utf-8"?-->
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">

<TextView

android:gravity="center_horizontal"/>

 

 

 

4.)  Run for output.

 

 

Steps:

 

1.) Create a project named ExpandedSearchView and set the information as stated in the image.

 

Build Target: Android 4.0

Application Name: ExpandedSearchView

Package Name: com. example. ExpandedSearchView

Activity Name: ExpandedSearchView

Min SDK Version: 14

 

 

2.) Open ExpandedSearchView.java file and write following code there:

 

 

package com.example.ExpandedSearchView;

import java.util.List;

import android.app.Activity;
import android.app.SearchManager;
import android.app.SearchableInfo;
import android.content.Context;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.Window;
import android.widget.SearchView;
import android.widget.TextView;

public class ExpandedSearchView extends Activity implements SearchView.OnQueryTextListener {

private SearchView mSearchView;
private TextView mStatusView;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().requestFeature(Window.FEATURE_ACTION_BAR);

setContentView(R.layout.main);

mStatusView = (TextView) findViewById(R.id.status_text);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);

MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.searchview_in_menu, menu);
MenuItem searchItem = menu.findItem(R.id.action_search);
mSearchView = (SearchView) searchItem.getActionView();
setupSearchView(searchItem);

return true;
}

private void setupSearchView(MenuItem searchItem) {

if (isAlwaysExpanded()) {
mSearchView.setIconifiedByDefault(false);
} else {
searchItem.setShowAsActionFlags(MenuItem.SHOW_AS_ACTION_IF_ROOM
| MenuItem.SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW);
}

SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
if (searchManager != null) {
List searchables = searchManager.getSearchablesInGlobalSearch();

SearchableInfo info = searchManager.getSearchableInfo(getComponentName());
for (SearchableInfo inf : searchables) {
if (inf.getSuggestAuthority() != null
&& inf.getSuggestAuthority().startsWith("applications")) {
info = inf;
}
}
mSearchView.setSearchableInfo(info);
}

mSearchView.setOnQueryTextListener(this);
}

public boolean onQueryTextChange(String newText) {
mStatusView.setText("Query = " + newText);
return false;
}

public boolean onQueryTextSubmit(String query) {
mStatusView.setText("Query = " + query + " : submitted");
return false;
}

public boolean onClose() {
mStatusView.setText("Closed!");
return false;
}
protected boolean isAlwaysExpanded() {
return true;
}
}

 

 

 

3.) Compile and build the project.
