Was it something like this:
import android.app.Activity;
import android.app.AlertDialog;
import android.app.AlertDialog.Builder;
import android.widget.EditText;
public class GuessNumberActivity extends Activity {
protected String mUserInput;
protected EditText mNumberField;
/*
* onCreate() and other code has been omitted for brevity!
*/
public void makeGuess() {
// Set mUserInput here!
mUserInput = mNumberField.getText().toString();
// Check to see if the user's number is correct
boolean isCorrect = GuessEngine.testGuess(mUserInput);
if(isCorrect == true){
AlertDialog.Builder builder = new AlertDialog.Builder(GuessNumberActivity.this);
builder.setTitle("Hooray!");
builder.setMessage("You did it!");
AlertDialog dialog = builder.create();
dialog.show();
}
}
}
