Android: Gestures not Performed Well

I want to use `Gesture` in my application. So I've checked out this documentation and createad a gesture already. Then copied that gesture to my `raw` folder which is located to `res/`. Everything is okay from here, then I impelement `OnGesturePerformedListener` as shown below: ``` if(!mLibrary.load()) { Log.d("Tag", "Couldn't load"); } else { Log.d("Tag", "Loaded"); GestureOverlayView gesture = (GestureOverlayView) findViewById(R.id.gestures); gesture.addOnGesturePerformedListener(this); } ``` And finally here is my listener: ``` public void onGesturePerformed(GestureOverlayView overlay, Gesture gesture) { ArrayList<Prediction> predictions = mLibrary.recognize(gesture); Log.d("Tag", "Performed"); // 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(); } } } ``` The problem is when I try to draw gesture nothing changes. Even `onGesturePerformed` not working. What's problem? I'm not sure but maybe layout could cause, here it is: ``` <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" android:background="@drawable/splash_bg" android:screenOrientation="portrait" > <android.gesture.GestureOverlayView android:id="@+id/gestures" android:layout_width="fill_parent" android:layout_height="0dip" android:layout_weight="1.0" /> </RelativeLayout> ``` Any help would be great.
