Question

My xml code:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/RelativeLayout1"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <RelativeLayout
        android:id="@+id/relativeLayout2"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_alignParentTop="true" android:visibility="invisible">


        <ImageButton
            android:id="@+id/video_playback_pause"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"/>


        <SeekBar
            android:id="@+id/seekbar_video"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" android:layout_below="@id/video_playback_pause" android:clickable=""/>

    </RelativeLayout>

    <VideoView
        android:id="@+id/videoView1"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_centerInParent="true" />

</RelativeLayout>

Now whe RelativeLayout and VideoView override.
the VideoView is show, and the RelativeLayout is hidden.
How to make the RelativeLayout on the top of VideoView?

Another problem is why the seekbar did not click?

I find that the priority of layout is decide by establish order?
But the problem of seekbar is still not resolve.

Try this…

 <?xml version="1.0" encoding="utf-8"?>
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/RelativeLayout1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >

<RelativeLayout
    android:id="@+id/relativeLayout2"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_alignParentTop="true" >


    <ImageButton
        android:id="@+id/video_playback_pause"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>


    <SeekBar
        android:id="@+id/seekbar_video"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" android:layout_below="@+id/video_playback_pause" android:clickable="true"/>

</RelativeLayout>

<VideoView
    android:id="@+id/videoView1"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_centerInParent="true" />

 </LinearLayout>

EDIT:

You can use the visibilty property as below

android:visibility="invisible" // invisible- just invisible the controls not the space
                               //gone - removes the allocated space too
                               //visible- shows the control

At run time also you can change

mylayout.setVisibilty(View.GONE)...
