To detect Gesture, you have to prepare your own gestures library. Refer to last post to create your gestures library using Gestures Builder, and copy to /res/raw.
package com.GestureMonitor;
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.TextView;
public class GestureMonitorActivity extends Activity {
GestureLibrary gestureLibrary = null;
GestureOverlayView gestureOverlayView;
TextView gestureResult;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
gestureResult = (TextView)findViewById(R.id.gestureresult);
gestureOverlayView = (GestureOverlayView)findViewById(R.id.gestures);
gestureLibrary = GestureLibraries.fromRawResource(this, R.raw.gestures);
gestureLibrary.load();
gestureOverlayView.addOnGesturePerformedListener(gesturePerformedListener);
}
OnGesturePerformedListener gesturePerformedListener
= new OnGesturePerformedListener(){
@Override
public void onGesturePerformed(GestureOverlayView view, Gesture gesture) {
// TODO Auto-generated method stub
ArrayList<Prediction> prediction = gestureLibrary.recognize(gesture);
if(prediction.size() > 0){
gestureResult.setText(prediction.get(0).name);
}
}};
}
