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.

You ought to fill entire gesture area with GestureOverlayView. Changing

android:layout_height="0dip"

to

android:layout_height="fill_parent"

Should do the trick.
