Gestureoverlayview (gesture recognition 2)

GestureOverlayView： A transparent overlay for gesture input , Used to recognize various gestures , It can be overlaid on the control , Other controls can also be included , There are three listening interfaces

1.GestureOverlayView.OnGestureListener// Gesture monitor

2.GestureOverlayView.OnGesturePerformed// Gesture execution listener

3.GestureOverlayView.onGesturing// Gesture execution listener

// A new project , It is used to recognize the matching between the input gesture and the pre-existing gesture Library

The project is currently , First in the Android simulator Gesture Builder( Android comes with ) Add your own gesture and the corresponding gesture name

After adding, it can be in the corresponding program mnt Medium sdcard Find the added gesture file in the path , Export it to , Then import it into the new program res Folder already built in raw in .

public class MainActivity extends ActionBarActivity {
	GestureOverlayView myGestureOverlayView;
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		myGestureOverlayView=(GestureOverlayView) findViewById(R.id.gestureOverlayView);
		// Find the preset gesture file 
		// Load all gestures of gesture file 
		// matching , distinguish 
		
		// The resource file has been loaded from the resource library 
		final GestureLibrary library= GestureLibraries.fromRawResource(this, R.raw.gestures);
		library.load();
		myGestureOverlayView.addOnGesturePerformedListener(new OnGesturePerformedListener() {
			
			@Override
			public void onGesturePerformed(GestureOverlayView arg0, Gesture gesture) {
				// TODO Auto-generated method stub
				// Read the contents of the hand potential library , Recognize gestures 
				ArrayList<Prediction> mygesture=library.recognize(gesture);
				Prediction prediction=mygesture.get(0);
				if(prediction.score>=5)
				{
					if(prediction.name.equals("exit"))
					{
						finish();
					}else if(prediction.name.equals("pervious"))
					{
						Toast.makeText(MainActivity.this, " The previous page ", Toast.LENGTH_SHORT).show();
					}else if(prediction.name.equals("next"))
					{
						Toast.makeText(MainActivity.this, " The next page ", Toast.LENGTH_SHORT).show();
					}
				}else{
					Toast.makeText(MainActivity.this, " No such gesture ", Toast.LENGTH_SHORT).show();
				}
			}
		});
