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;
	@Override
	protected 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() {

			@Override
			public 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，
