打開模擬器，打開軟件：
點擊Add gesture 新建手勢：
這個例子我們用兩個手勢
將手勢識別庫從sdcard卡中導出，在res文件下新建raw文件，將導出的gesture文件粘貼到raw文件下
Java代碼：
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;
/**
* 手勢識別
* @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);
//從資源文件中將手勢庫加載進來
gl = GestureLibraries.fromRawResource(this, R.raw.gestures);
gl.load();
//從xml中取出GestureOverlayView控件
gov = (GestureOverlayView) findViewById(R.id.gestureOverlayView1);
//為GestureOverlayView控件添加監聽
gov.addOnGesturePerformedListener(new OnGesturePerformedListener() {
@Override
public void onGesturePerformed(GestureOverlayView overlay, Gesture gesture) {
//識別手勢，返回一個類型為Prediction的列表
ArrayList<Prediction> list = gl.recognize(gesture);
Prediction pre = list.get(0);
//如果匹配度大於1，表示可以識別，否則提示無法識別
if(pre.score > 1){
//判斷名字是否與手勢庫的名字相同
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代碼：
<?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"
android:orientation="vertical" >
<android.gesture.GestureOverlayView
android:id="@+id/gestureOverlayView1"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
</android.gesture.GestureOverlayView>
</LinearLayout>
