  1. POPassing a counter from one Activity to another
    text
    copied!<p>I have an class <code>Voice</code>, which extends <code>Activity</code>, and contains a counter. When the user answers correctly, the counter adds one via <code>counter++;</code></p> <pre><code>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; } </code></pre> <p>This score, is bundled and passed on to the next activity "What" within a string "your score is 1". </p> <pre><code>protected void onActivityResult(int requestCode, int resultCode, Intent data) { if (requestCode == check &amp;&amp; resultCode == RESULT_OK) { ArrayList&lt;String&gt; results = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS); lv.setAdapter( new ArrayAdapter&lt;String&gt;(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(); } } </code></pre> <p>The next <code>Activity</code>, <code>What</code>, gets this <code>Bundle</code> and displays it fine using <code>setText(gotScore)</code></p> <pre><code>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); </code></pre> <p>..this is when things go bad :(</p> <p>On <code>What</code> I have another question tied to a counter as well. When the user answers correctly the counter adds one via <code>counter++;</code> and it does. However, it changes the <code>txview</code> <code>string</code> 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 <code>What</code> reads "your score is 2". This gets passes to the next activity in <code>Bundle keeper</code>, which holds the aggregate score.</p> <p>I've read a few tutorials on passing an <code>int</code> verses a <code>string</code>, but some of the code they use like <code>getInt</code> is not recognized. I'm stumped.</p>
