    text
    copied!<p>As the title says I want to transfer data, in this case the information introduced by the user on an <code>EditText</code> and a <code>Spinner</code>, from one activity to another.</p> <p>I am following a tutorial from a book but it doesn't work (I think its not complete). Here the code of the program:</p> <pre><code> public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); this.setContentView(R.layout.main); this.location=(EditText)findViewById(R.id.location); this.cuisine=(Spinner)findViewById(R.id.cuisine); this.grabReviews=(Button)findViewById(R.id.get_reviews_button); ArrayAdapter adapter = ArrayAdapter.createFromResource(this, R.array.cuisine, android.R.layout.simple_spinner_item); adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); this.cuisine.setAdapter(adapter); this.grabReviews.setOnClickListener(new OnClickListener() { public void onClick(View v) { handleGetReviews(); } } ); } private void handleGetReviews() { RestaurantsActivity application= (RestaurantsActivity) getApplication(); application.setReviewCriteriaCuisine(this.cuisine.getSelectedItem().toString()); application.setReviewCriteriaLocation(this.location.getText().toString()); Intent intent=new Intent(Constants.INTENT_ACTION_VIEW_LIST); startActivity(intent); } </code></pre> <p>This code above doesn't work. I dont understand four things:</p> <p>-<code>RestaurantsActivity</code> must be the actual activity right?</p> <p>-In all the examples I have seen over the internet there is an application extends class, in this example there isnt.</p> <p>-<code>setReviewCriteria</code> function is missing </p> <p>-Where does <code>Constants.INTENT_ACTION_VIEW_LIST</code> come from ?</p>
