android手势识别

详细步骤不说了

手势识别代码    http://download.csdn.net/detail/zhupengqq/9578532

运行上边这个项目之后，会生成这样一个手势识别库gestures，新建一个项目，

在res下面，建立一个raw文件夹，然后引入这个库

下面是具体实例：

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical" >    <android.gesture.GestureOverlayView        android:id="@+id/gestureOverlayView1"        android:layout_width="wrap_content"        android:layout_height="wrap_content" >        <ImageView            android:id="@+id/img1"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:src="@drawable/aa" />    </android.gesture.GestureOverlayView></LinearLayout>

<span style="font-size:14px;">package com.example.gusturedetecterdemo2;import java.util.ArrayList;import android.os.Bundle;import android.app.Activity;import android.gesture.Gesture;import android.gesture.GestureLibraries;import android.gesture.GestureLibrary;import android.gesture.GestureOverlayView;import android.gesture.GestureOverlayView.OnGesturePerformedListener;import android.gesture.Prediction;import android.view.GestureDetector;import android.view.GestureDetector.SimpleOnGestureListener;import android.view.Menu;import android.view.MotionEvent;import android.view.View;import android.view.View.OnTouchListener;import android.widget.ImageView;import android.widget.SimpleAdapter;import android.widget.Toast;public class MainActivity2 extends Activity {private GestureOverlayView gestureOverlayView;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main2);gestureOverlayView=(GestureOverlayView) findViewById(R.id.gestureOverlayView1);final GestureLibrary library=GestureLibraries.fromRawResource(MainActivity2.this, R.raw.gestures);library.load();gestureOverlayView.addOnGesturePerformedListener(new OnGesturePerformedListener() {@Overridepublic void onGesturePerformed(GestureOverlayView overlay, Gesture gesture) {// TODO Auto-generated method stu  读出手势//读出手势中的内容，识别手势ArrayList<Prediction> mygesture=library.recognize(gesture);Prediction predction=mygesture.get(0);if(predction.score>5.0){if(predction.name.equals("宿")){Toast.makeText(MainActivity2.this, "一元钱代金券", Toast.LENGTH_LONG).show();finish();}if(predction.name.equals("五角")){Toast.makeText(MainActivity2.this, "五角钱代金券", Toast.LENGTH_LONG).show();}if(predction.name.equals("一")){Toast.makeText(MainActivity2.this, "两角钱代金券", Toast.LENGTH_LONG).show();}}else{Toast.makeText(MainActivity2.this, "没有该手势", Toast.LENGTH_LONG).show();}}});}}</span>

运行之后，滑动界面，就会出现手势识别，
