How can I launch my Android activities with the sp

I want to alter this switch such that instead of clicking the buttons my activities will launch by speaking the name of the associated fruit. For instance, the Apple class will launch by speaking the word "Apple". How should I rewrite this switch? All of my attempts at doing this have not seemed to work thus far. Any answers provided will be greatly appreciated. Thank you!

                            Intent i = new Intent(this, Apple.class);
                // start the activity based on the Intent

            case R.id.five:
                    Intent m = new Intent(this, Strawberry.class);

                    // start the activity based on the Intent
                    startActivityForResult(m, 0);
                    finish();
                    break;

            case R.id.six:
                    Intent n = new Intent(this, Kiwi.class);

                    // start the activity based on the Intent
                    startActivity(n);
                    finish();
                    break;
                    default:
                    finish();
        }

    };
}

Is this the correct way to handle the voice activity result?

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (requestCode == VOICE_RECOGNITION_REQUEST_CODE)

            //If Voice recognition is successful then it returns RESULT_OK
            if(resultCode == RESULT_OK) {

                ArrayList<String> textMatchList = data
                .getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);

                if (!textMatchList.isEmpty()) {
                    // If first Match contains the word 'apple'
                    // Then start the apple activity.
                    if (textMatchList.get(0).contains("apple")) {
                            // create an intent indicating we want
                // to start the activity.

                            Intent i = new Intent(this, Apple.class);
                // start the activity based on the Intent
                startActivity(i);
                finish();
                break;

I feel like something is missing after this line...

if (textMatchList.get(0).contains("apple")) {

Here is a sample tutorial on how to use Android voice recognition. You need to handle the search result in OnActivityResult and do a string match to apple, banana,grape and so on.. if the string match is found, launch the respective activity!
