Hello, i am trying to place a layout behind of_gl_surface_container in android and make of_gl_surface_container transparent, so that i can draw things to the surface while seeing whats on the view behind the surface.

I tried making clear color ofClear(ofColor(0, 0, 0, 0)) and setting of_gl_surface_container background color to transparent. But it does not work. Can i please know whether this is possible or not?

My draw function:-

void ofApp::draw(){
    ofColor clearColor;
    clearColor.r = 0;
    clearColor.g = 0;
    clearColor.b = 0;
    clearColor.a = 0;
    ofClear(clearColor);
    ofSetColor(0, 255, 0, 125);
    ofDrawRectangle(50, 50, 100, 100);
}

My XML:-

<RelativeLayout
    android:id="@+id/relativeLayout1"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    xmlns:android="http://schemas.android.com/apk/res/android">

    <LinearLayout
        android:id="@+id/sd"
        android:orientation="vertical"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:background="@android:color/holo_green_light" />

    <RelativeLayout
        android:id="@+id/of_gl_surface_container"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:background="@color/clearColor"/>
    <!-- add here other views' layouts -->
</RelativeLayout>
