打开模拟器，打开软件：
点击Add gesture 新建手势：
这个例子我们用两个手势
将手势识别库从sdcard卡中导出，在res文件下新建raw文件，将导出的gesture文件粘贴到raw文件下
Java代码：
package cn.mrzhu.test25;
import java.util.ArrayList;
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.os.Bundle;
import android.widget.Toast;
/**
* 手势识别
* @author root
*
*/
public class Main extends Activity {
private GestureOverlayView gov;
private GestureLibrary gl;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//从资源文件中将手势库加载进来
gl = GestureLibraries.fromRawResource(this, R.raw.gestures);
gl.load();
//从xml中取出GestureOverlayView控件
gov = (GestureOverlayView) findViewById(R.id.gestureOverlayView1);
//为GestureOverlayView控件添加监听
gov.addOnGesturePerformedListener(new OnGesturePerformedListener() {
@Override
public void onGesturePerformed(GestureOverlayView overlay, Gesture gesture) {
//识别手势，返回一个类型为Prediction的列表
ArrayList<Prediction> list = gl.recognize(gesture);
Prediction pre = list.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(pre.score > 1){
//判断名字是否与手势库的名字相同
if(pre.name.equals("haha")){
Toast.makeText(Main.this, "Recognize the haha", Toast.LENGTH_SHORT).show();
}else if(pre.name.equals("xin")){
Toast.makeText(Main.this, "Recognize the xin", Toast.LENGTH_SHORT).show();
}
}else{
Toast.makeText(Main.this, "Can't Recognize", Toast.LENGTH_SHORT).show();
}
}
});
}
}
main.xml代码：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
