Question

When trying you get the activity to change on the click of a button, I found you had to use Intent. But when used in my code it does not seem to work. Are there any problems with the code I have?

  public class SearchActivity extends Activity implements OnClickListener{

    private ListView recipes;
    Intent intent;
    Button button;
    EditText input;

    public void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);

          setContentView(R.layout.searchlist);

          //EditText input = (EditText)findViewById(R.id.recipeName);
          button = (Button)findViewById(R.id.submit);
          input = (EditText)findViewById(R.id.recipeName);

          //recipes = (ListView)findViewById(R.id.recipes);
          //recipes.setAdapter(new ArrayAdapter<String> (this, R.layout.main, getResources().getStringArray(R.array.BaconSandwich)));
          button.setOnClickListener(this);
      }

      public void onClick(View clicked) {

          String value = input.getText().toString();
          Toast.makeText(this, value, Toast.LENGTH_SHORT).show();

          if(clicked == button) {
            recipes = (ListView)findViewById(R.id.recipes);
            Toast.makeText(this, "It is working for this item.", Toast.LENGTH_SHORT).show();
            Intent i = new Intent(SearchActivity.this, RecipeMethodActivity.class);
            SearchActivity.this.startActivity(i);
          }
      }

Im not sure if it is just a simple naming error, or the way I am calling it is wrong. Any help would be great.

Also I have added the activity I want to change to (RecipeMethodActivity) into the Android Manifest.

You need to check for the view’s Id in your onClick method, like this:

public void onClick(View clicked) {

      String value = input.getText().toString();
      Toast.makeText(this, value, Toast.LENGTH_SHORT).show();

      if(clicked.getId() == R.id.submit) {
        recipes = (ListView)findViewById(R.id.recipes);
        Toast.makeText(this, "It is working for this item.", Toast.LENGTH_SHORT).show();
        Intent i = new Intent(SearchActivity.this, RecipeMethodActivity.class);
        SearchActivity.this.startActivity(i);
      }
  }
