Widget that calls speech recognition app

Question

I\'m trying to create a widget that contains a single ImageView which, when clicked, starts speech recognition application. I\'ve never worked with widgets and pending inten

This is fully functional, and it's based off the ListView widget in the Android SDK. It's not particularly for a widget, but I'm sure you can modify it so that it works for a widget.

Create an activity called SearchActivity:

// CustomSearch (View) & ISearch (Interface) are objects that I created and are irrelevant
public class SearchActivity extends AppCompatActivity implements ISearch
{
    // Variables
    private CustomSearch mSearchView;


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

        mSearchView = (CustomSearch)findViewById(R.id.search);
        mSearchView.setPendingComponentName(getComponentName());
        mSearchView.setSearchListener(this);
    }

    @Override
    protected void onNewIntent(Intent intent)
    {
        if (Intent.ACTION_SEARCH.equals(intent.getAction()))
        {
            String query = intent.getStringExtra(SearchManager.QUERY);
            Log.i("SEARCH >", "You said: " + query);
        }
    }
}

Add activity to the AndroidManifest.xml

In your custom Widget/View:

buttonVoice.setOnClickListener(new View.OnClickListener() 
{
    @Override
    public void onClick(View v)
    {
        // Get activity from either SearchableInfo or ComponentName
        ComponentName searchActivity = mComponentName;

        // Wrap component in intent
        Intent queryIntent = new Intent(Intent.ACTION_SEARCH);
        queryIntent.setComponent(searchActivity);

        // Wrap query intent in pending intent
        PendingIntent pending = PendingIntent.getActivity(getContext(), 0, queryIntent, PendingIntent.FLAG_ONE_SHOT);

        // Create bundle now because if we wrap it in pending intent, it becomes immutable
        Bundle queryExtras = new Bundle();

        // Create voice intent
        Intent voiceIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZER_SPEECH);
        voiceIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
        voiceIntent.putExtra(RecognizerIntent.EXTRA_PROMPT, "Speak");
        voiceIntent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, searchActivity
        voiceIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

        // Wrap the pending intent & bundle inside the voice intent
        voiceIntent.putExtra(RecognizerIntent.EXTRA_RESULTS_PENDINGINTENT, pending);
        voiceIntent.putExtra(RecognizerIntent.EXTRA_RESULTS_PENDINGINTENT_BUNDLE, queryExtras);

        // Start the voice search
        getContext().startActivity(voiceIntent);
    }
}
