Create “history” to SearchView on ActionBar

Question

I want to have history on my SearchView, I\'ve been googling around, and the only sensible(?) tutorial I found was this, but that\'s just for like Gingerbread, not API>14.

This page talks about how you can implement history for SearchView.

http://developer.android.com/guide/topics/search/adding-recent-query-suggestions.html

First, you have to create a content provider:

public class MySuggestionProvider extends SearchRecentSuggestionsProvider {
    public final static String AUTHORITY = "com.example.MySuggestionProvider";
    public final static int MODE = DATABASE_MODE_QUERIES;

    public MySuggestionProvider() {
        setupSuggestions(AUTHORITY, MODE);
    }
}

Then declare the content provider in your application manifest like this:

    
    ...

Then add the content provider to your searchable configurations like this:

You can call saveRecentQuery() to save queries at any time. Here's how you can do it in the onCreate method for your activity:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    Intent intent  = getIntent();

    if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
        String query = intent.getStringExtra(SearchManager.QUERY);
        SearchRecentSuggestions suggestions = new SearchRecentSuggestions(this,
                MySuggestionProvider.AUTHORITY, MySuggestionProvider.MODE);
        suggestions.saveRecentQuery(query, null);
    }
}

To clear search history you simply need to call SearchRecentSuggestions's method clearHistory() like this:

SearchRecentSuggestions suggestions = new SearchRecentSuggestions(this,
        HelloSuggestionProvider.AUTHORITY, HelloSuggestionProvider.MODE);
suggestions.clearHistory();
