在菜单按钮上使用android手势

Question

我想要的是有一个选项菜单,用户可以选择在以下菜单之间导航:

1. 触摸按钮,然后按下轨迹球以选择它
2. 从Gestures Builder绘制预定义手势

就像现在一样,我已经创建了我的按钮OnClickListener和手势GestureOverlayView.然后我选择开始一个新的,Activity取决于使用按下按钮还是执行手势.但是,当我尝试绘制手势时,它不会被拾取.仅识别按钮.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!

如果我理解正确，您想在同一视图上执行单击操作和手势操作，我不确定如何实现这一点，但是，我们可以在按钮后面有不可见的视图来处理手势，而顶部的按钮将处理单击活动如常。

默认计算器应用程序使用此方法在正常模式和高级模式之间进行切换。
