to draw the circle on touch with the finger use this code this is with the
gesture listener
public class GesturesActivity extends Activity implements
OnGesturePerformedListener {
private GestureLibrary mLibrary;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mLibrary = GestureLibraries.fromRawResource(this, R.raw.spells);
if (!mLibrary.load()) {
finish();
}
GestureOverlayView gestures = (GestureOverlayView)
findViewById(R.id.gestures);
gestures.addOnGesturePerformedListener(this);
}
public void onGesturePerformed(GestureOverlayView overlay, Gesture
gesture) {
ArrayList<Prediction> predictions = mLibrary.recognize(gesture);
// We want at least one prediction
if (predictions.size() > 0) {
Prediction prediction = predictions.get(0);
// We want at least some confidence in the result
if (prediction.score > 1.0) {
// Show the spell
Toast.makeText(this, prediction.name,
Toast.LENGTH_SHORT).show();
}
}
}
}
