please help me thanks

Try this

<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content"
    android:orientation="vertical">
<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content"
    android:orientation="horizontal">
<TextView 
    android:id="@+id/label"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="URL:"
    android:layout_alignBaseline="@+id/entry"
    android:layout_alignParentLeft="true"/>
    />
<EditText 
    android:id="@+id/entry"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_toRightOf="@id/label"
    android:layout_alignParentTop="true"
    />
</LinearLayout>
<Button 
    android:id="@+id/button" 
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" 
    android:layout_gravity="center_horizontal"
    android:paddingRight="30px" 
    android:paddingLeft="30px" 
    android:text="Go..." 
    />
</LinearLayout>

Or use RelativeLayout

Use RelativeLayout instead of Linear one and get use of android:rightOf.

As far as I understood, you cannot use such _toRightTop, _BOTTOM attributes with a linear Layout. Use RelativeLayout and all should be fine.

Use relative layout instead of linear layout.One advantage of this is that it improves your performance.if you try to search and id suing a linear layout,it will check with every component of the linear layout and try to match with its id but with relativer layout it will be faster as all elements are defined relative to each other.
