Android（GestureOverlayView）用法

Question

我想知道，在Android中如何实现GestureOverLayView。我尝试通过在互联网上寻找一些代码，但我还没有找到任何方便和容易方式来实现。请给我一些的例子到代码。

公共类GestureTest扩展Activity实现OnGesturePerformedListener私有GestureLibrary gestureLib;

/** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
      super.onCreate(savedInstanceState); 
      GestureOverlayView gestureOverlayView = new GestureOverlayView(this); 
      View inflate = getLayoutInflater().inflate(R.layout.main, null); 
      gestureOverlayView.addView(inflate); 
      gestureOverlayView.addOnGesturePerformedListener(this); 
      gestureLib = GestureLibraries.fromRawResource(this, R.raw.gestures); 
      if (!gestureLib.load()) { 
        finish(); 
      } 
      setContentView(gestureOverlayView); 
    } 

    @Override 
    public void onGesturePerformed(GestureOverlayView overlay, Gesture gesture) { 
      ArrayList<Prediction> predictions = gestureLib.recognize(gesture); 
      for (Prediction prediction : predictions) { 
        if (prediction.score > 1.0) { 
          Toast.makeText(this, prediction.name, Toast.LENGTH_SHORT) 
              .show(); 
        } 
      } 
    } 

}
