What I want is to have an options
menu where the user can choose to navigate the
menu between:
1) touching a button and then pressing
down on the trackball to select it, and
2) drawing predefined gestures from Gestures Builder
As it stands now, I have created my buttons with OnClickListener and the gestures with GestureOverlayView. Then I select starting a new Activity depending on whether the using pressed a button or executed a gesture. However, when I attempt to draw a gesture, it is not picked up. Only pressing the buttons is recognized. The following is my code:
public class
Menu extends Activity implements OnClickListener, OnGesturePerformedListener {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//create TextToSpeech
myTTS = new TextToSpeech(this, this);
myTTS.setLanguage(Locale.US);
//create Gestures
mLibrary = GestureLibraries.fromRawResource(this, R.raw.gestures);
if (!mLibrary.load()) {
finish();
}
// Set up click listeners for all the buttons.
View playButton = findViewById(R.id.play_button);
playButton.setOnClickListener(this);
View instructionsButton = findViewById(R.id.instructions_button);
instructionsButton.setOnClickListener(this);
View modeButton = findViewById(R.id.mode_button);
modeButton.setOnClickListener(this);
View statsButton = findViewById(R.id.stats_button);
statsButton.setOnClickListener(this);
View exitButton = findViewById(R.id.exit_button);
exitButton.setOnClickListener(this);
GestureOverlayView gestures = (GestureOverlayView) findViewById(R.id.gestures);
gestures.addOnGesturePerformedListener(this);
}
public void onGesturePerformed(GestureOverlayView overlay, Gesture gesture) {
ArrayList<Prediction> predictions = mLibrary.recognize(gesture);
// We want at least one prediction
if (predictions.size() > 0) {
Prediction prediction = predictions.get(0);
// We want at least some confidence in the result
if (prediction.score > 1.0) {
// Show the gesture
Toast.makeText(this, prediction.name, Toast.LENGTH_SHORT).show();
//User drew symbol for PLAY
if (prediction.name.equals("Play")) {
myTTS.shutdown();
//connect to game
// User drew symbol for INSTRUCTIONS
} else if (prediction.name.equals("Instructions")) {
myTTS.shutdown();
startActivity(new Intent(this, Instructions.class));
// User drew symbol for MODE
} else if (prediction.name.equals("Mode")){
myTTS.shutdown();
startActivity(new Intent(this, Mode.class));
// User drew symbol to QUIT
} else {
finish();
}
}
}
}
@Override
public void onClick(View v) {
switch (v.getId()){
case R.id.instructions_button:
startActivity(new Intent(this, Instructions.class));
break;
case R.id.mode_button:
startActivity(new Intent(this, Mode.class));
break;
case R.id.exit_button:
finish();
break;
}
}
Any suggestions would be greatly appreciated!
