手势保存了就可以开始识别了。

//从资源文件中将手势库加载进来if(mGre==null){Log.e("","手势");mGre=GestureLibraries.fromRawResource(this,R.raw.yl_yl);//无此句出错mGre.load();}//从xml中取出GestureOverlayView控件mGov=(GestureOverlayView)findViewById(R.id.gesture);mGov.setGestureColor(Color.BLACK);//手势颜色mGov.setGestureStrokeWidth(15);//手势宽度//为GestureOverlayView控件添加监听mGov.addOnGesturePerformedListener(this);

开始识别：

//识别手势，返回一个类型为Prediction的列表ArrayList<Prediction>gestureList=mGre.recognize(gesture);if(gestureList.size()>0){Predictionpd=gestureList.get(0);//如果匹配度大于1，表示可以识别，否则提示无法识别if(pd.score>3){//判断名字是否与手势库的名字相同if(pd.name.equals("勾")){Intentintent=newIntent(MainActivity.this,SecondActivity.class);startActivity(intent);Toast.makeText(MainActivity.this,"已识别",Toast.LENGTH_SHORT).show();}else{Toast.makeText(MainActivity.this,"名字不匹配",Toast.LENGTH_SHORT).show();}}else{Toast.makeText(MainActivity.this,"无法识别",Toast.LENGTH_SHORT).show();}}

最后别忘了解绑监听：

protectedvoidonDestroy(){mGov.removeOnGesturePerformedListener(this);super.onDestroy();}
