Things not working if I add tileView not as 'setContentView(tileView)'

[ghost]

In MainActivity.xml,

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
     xmlns:android="http://schemas.android.com/apk/res/android"
     xmlns:tools="http://schemas.android.com/tools"
     android:id="@+id/activity_main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#bbbbbb"
    tools:context="com.packagename.main_activity.MainActivity">

    <!-- Im gonna add tileView inside this container below -->
    <RelativeLayout
        android:id="@+id/tileview_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

</RelativeLayout>

I created a tileView the same way the sample code did. Then at the very end, instead of

setContentView(tileView);

I did:

RelativeLayout tileViewContainer = (RelativeLayout) findViewById(R.id.tileview_container);
tileViewContainer.addView(tileView);

The tileView appears perfectly well. But now, things like

 tileView.addMarker( someView, 250, 500, -0.5f, -1.0f );

don't work..

I tried to look inside the code, but didn't get to figure out how to get it to work.

Can you give me some idea on how to solve this?

You need layout params for any child of your RelativeLayout. Please research basic Android operations before creating a TileView issue. Thanks
