Question

I have an class Voice, which extends Activity, and contains a counter. When the user answers correctly, the counter adds one via counter++;

public class Voice  extends Activity implements OnClickListener{
    ListView lv;
    static final int check = 111;
    int counter_score;
    TextView txView;
    MediaPlayer ourSong;
    ImageView display;

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

    private void initialize() {
        lv = (ListView)findViewById(R.id.lvVoiceReturn);
        Button b = (Button)findViewById(R.id.imageButtonSelector);
        txView = (TextView)findViewById(R.id.counter);
        b.setOnClickListener(this);
        counter_score=0;
    }

This score, is bundled and passed on to the next activity “What” within a string “your score is 1”.

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == check && resultCode == RESULT_OK) {
        ArrayList<String> results = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
        lv.setAdapter( new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, results));

        if(results.contains("hey") || results.contains("a") || results.contains("ay")) {
            //toast referenced to xml the after 400ms
            counter_score++;
            txView.setText("Your Score is" + " " + counter_score);

            AlertDialog dialogBuilder = new AlertDialog.Builder(this).create();
            dialogBuilder.setTitle("AWSOME");
            dialogBuilder.setMessage("¡Your current score is" + counter_score);
            dialogBuilder.setIcon(R.drawable.ic_mark);
            dialogBuilder.show();

            ourSong = MediaPlayer.create(Voice.this, R.raw.rightsound2);
            ourSong.start();
            Thread timer = new Thread() {
                public void run(){
                try {
                    sleep(2500);
                }catch (InterruptedException e){
                    e.printStackTrace();
                } finally {
                    String score = txView.getText().toString();
                    Bundle keeper = new Bundle();
                    keeper.putString("key", score);
                    Intent putScore = new Intent(Voice.this, What.class);
                    putScore.putExtras(keeper);
                    startActivity(putScore);
                }
            }
        };

        timer.start();
    }
}

The next Activity, What, gets this Bundle and displays it fine using setText(gotScore)

public class What  extends Activity implements OnClickListener {
    ListView lv;
    static final int check = 111;
    private int counter_score;
    TextView txView;
    MediaPlayer ourSong;
    ImageView display;
    String gotScore;

    String classes[] = {"What", "Pagina", "What", "example3", "example4", "example5", 
                        "example6"};

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.letter_b);
        initialize();
        Bundle gotKeeper = getIntent().getExtras();
        gotScore = gotKeeper.getString("key");
        txView.setText(gotScore);
    }

    private void initialize() {
        // TODO Auto-generated method stub
        lv = (ListView)findViewById(R.id.lvVoiceReturn);
        Button b = (Button)findViewById(R.id.imageButtonSelector);
        txView = (TextView)findViewById(R.id.counter);
        b.setOnClickListener(this);

..this is when things go bad 🙁

On What I have another question tied to a counter as well. When the user answers correctly the counter adds one via counter++; and it does. However, it changes the txview string to “your score is 1”. I can’t get it to add 1 to the counter result passed from the previous activity within the string, so that the counter on What reads “your score is 2”. This gets passes to the next activity in Bundle keeper, which holds the aggregate score.

I’ve read a few tutorials on passing an int verses a string, but some of the code they use like getInt is not recognized. I’m stumped.

Answer 1

What you’re bundling and passing to the What activity is not the counter but the string “Your score is 1”. If you want to increment that number in the next activity then you should be sending just the integer value and constructing whatever string you need there instead.

I’m not too sure I know what you mean by getInt() is not recognized. In any case, make things easier for yourself when passing counter from one activity to another. If it is an int and you plan on manipulating like an int in the receiving activity then add it to the bundle as an int. For example:

    Bundle keeper = new Bundle();
    keeper.putInt("key", counter_score);

And retrieve it from the bundle with:

    Bundle gotKeeper = getIntent().getExtras();
    int score = gotKeeper.getInt("key");
