我想要的是有一个选项菜单,用户可以在其中选择在以下菜单之间导航:
- 触摸一个按钮,然后按下轨迹球将其选中
- 从 Gestures Builder 绘制预定义的手势
就目前而言,我已经创建了我的按钮OnClickListener
和手势GestureOverlayView
。然后我Activity
根据使用按下按钮还是执行手势来选择开始新的。但是,当我尝试绘制手势时,它没有被拾取。只有按下按钮才会被识别。以下是我的代码:
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;
}
}
任何建议将不胜感激!
