This example shows how you can create search view onto the action bar and set it tobe expanded always.
Algorithm:
1.) Create a new project by File-> New -> Android Project name it ExpandedSearchView.
2.) Create and write following into menu\searchview_in_menu.xml:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/action_search"
android:title="Search"
android:icon="@android:drawable/ic_menu_search"
android:showAsAction="always"
android:actionViewClass="android.widget.SearchView" />
</menu>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/action_search"
android:title="Search"
android:icon="@android:drawable/ic_menu_search"
android:showAsAction="always"
android:actionViewClass="android.widget.SearchView" />
</menu>
3.) Write following into main.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
android:id="@+id/status_text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"/>
</LinearLayout>
android:id="@+id/status_text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"/>
</LinearLayout>
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.view.MenuItem;
import android.view.Window;
import android.widget.SearchView;

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 implementsSearchView.OnQueryTextListener {
private SearchView mSearchView;
private TextView mStatusView;
private TextView mStatusView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().requestFeature(Window.FEATURE_ACTION_BAR);
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);
}
}
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);
inflater.inflate(R.menu.searchview_in_menu, menu);
MenuItem searchItem = menu.findItem(R.id.action_search);
mSearchView = (SearchView) searchItem.getActionView();
setupSearchView(searchItem);
return true;
}
}
if (isAlwaysExpanded()) {
mSearchView.setIconifiedByDefault(false);
} else {
searchItem.setShowAsActionFlags(MenuItem.SHOW_AS_ACTION_IF_ROOM
| MenuItem.SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW);
}
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<SearchableInfo> searchables =searchManager.getSearchablesInGlobalSearch();
if (searchManager != null) {
List<SearchableInfo> 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);
}
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;
}
mStatusView.setText("Query = " + newText);
return false;
}
public boolean onQueryTextSubmit(String query) {
mStatusView.setText("Query = " + query + " : submitted");
return false;
}
mStatusView.setText("Query = " + query + " : submitted");
return false;
}
public boolean onClose() {
mStatusView.setText("Closed!");
return false;
}
protected boolean isAlwaysExpanded() {
return true;
}
}
mStatusView.setText("Closed!");
return false;
}
protected boolean isAlwaysExpanded() {
return true;
}
}
3.) Compile and build the project.
