公共类GestureTest扩展了Activity实现OnGesturePerformedListener {         私人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();
                    }
            }
    }

}
