Android Studio SearchView on Toolbar Page

The SearchView widget in Android Studio is used to provide a search bar in your application's toolbar. This allows users to easily search for specific information within your app.

Syntax

To add a SearchView to your toolbar, you can use the following syntax in your menu.xml file:

<item android:id="@+id/search"
      android:title="Search"
      android:icon="@drawable/ic_search"
      app:actionViewClass="androidx.appcompat.widget.SearchView"
      app:showAsAction="collapseActionView|ifRoom"/>

In your activity code, you'll need to set up the SearchView to handle user input and display search results. Here's an example:

public class MainActivity extends AppCompatActivity implements SearchView.OnQueryTextListener {
    private SearchView searchView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Toolbar toolbar = findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        
        searchView = (SearchView) findViewById(R.id.search);
        searchView.setOnQueryTextListener(this);
    }

    @Override
    public boolean onQueryTextSubmit(String query) {
        // Code to handle search query submission
        return false;
    }

    @Override
    public boolean onQueryTextChange(String newText) {
        // Code to handle search query text changes
        return false;
    }
}

Example

Here's an example SearchView in action:

Output

When the user types into the SearchView and presses "Enter" or submits the search query, your app will need to display search results. This can be done in a variety of ways, such as displaying a list of search results or highlighting matching text within your app's content.

Explanation

The SearchView widget is part of the Android Material Design library, and can be customized to fit the theme and style of your application. By default, the SearchView will expand when the user clicks on it, allowing them to enter a search query. You can use the setOnQueryTextListener method to handle user input and display search results.

In addition to the basic search functionality, the SearchView widget provides support for voice search, query suggestions, and autocomplete suggestions. These features can help improve the user experience and make it easier for users to find the information they're looking for.

Use

The SearchView widget is useful in any application that has a large amount of content or data that can be searched. This includes apps that display lists of items, such as music players or shopping apps, as well as apps that provide access to large amounts of text-based content, such as news apps or reference guides.
