How do I pass extra variables during a search invoked by a SearchView/ Widget?

I am successfully using a search widget in my action bar to perform a search following this guide. The search is fine, but I'm wondering how to pass additional variables on a search. The same guide states I can override

onSearchRequested()
, but this doesn't seem to work with a search widget.


  • Override in question:

    @Override
    public boolean onSearchRequested() {
    Bundle appData = new Bundle();
    appData.putString("KEY", "VALUE");
    startSearch(null, false, appData, false);
    return true;
    }

  • Getting the bundle in my activity class:

    protected void onCreate(Bundle savedInstanceState) {
    // ...
    Intent intent = getIntent();
    Bundle appData = intent.getBundleExtra(SearchManager.APP_DATA);
    String value = appData.getString("KEY");
    Log.d("VALUE", value);
    // ...
    }



My application crashes upon creating the search class because
appData
is always
null
.

Note



onSearchRequested()
is called, but the bundle does not make it to my
onCreate()
method.

All extras from the passed intent are
{user_query=my-query, query=my-query}
.

Answer

It seems the only way to do this is to intercept new activities created in your activity which is search-enabled. To do this we override the startActivity() method. We can then check to make sure the activity is indeed the search activity, then add an extra to the intent. The working code is below.

@Override
public void startActivity(Intent intent) {      
    // check if search intent
    if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
        intent.putExtra("KEY", "VALUE");
    }

    super.startActivity(intent);
}

You can then grab your extra as you would any other extra in your search activity using:

mValue = intent.getStringExtra("KEY");
