Android - Want to optimize Layout

I have created the below layout using Linear Layout , its running fine but i have one doubt that it can be optimized because i have created this UI using nested Linear Layout , i think its not well.

So Can you please help me to optimize this Linear Layout either by using Relative Layout or else ?

I have defined a layout like:

<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  android:padding="6dip">

 <LinearLayout
        android:orientation="vertical"
        android:layout_width="wrap_content"
        android:layout_weight="1"
        android:layout_height="fill_parent"
        android:layout_marginLeft="10dip">

        <TextView
            android:id="@+id/txtViewTitle"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:gravity="center_vertical"
            android:textSize="18dip"
            android:text="hello"
        />
        <TextView
            android:id="@+id/txtViewDescription"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:gravity="center_vertical"
            android:textSize="14dip"
            android:text="hello"
            />
    </LinearLayout>       

     <ImageView
      android:id="@+id/image"
      android:layout_width="50dip"
      android:layout_height="fill_parent" 
      android:src="@drawable/arrow"
      android:layout_marginLeft="3dip"
      android:scaleType="center"/>

</LinearLayout>

Here is a refactoring of your code using RelativeLayout:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent" android:layout_height="wrap_content"
    android:padding="6dip">
    <ImageView android:layout_marginLeft="3dip" android:id="@+id/image"
        android:src="@drawable/arrow_cell"
        android:layout_width="50dip" android:scaleType="center"
        android:layout_alignParentRight="true" android:layout_height="wrap_content" android:layout_centerVertical="true"></ImageView>
    <TextView android:textSize="18dip" android:layout_height="wrap_content"
        android:layout_width="fill_parent" android:id="@+id/txtViewTitle"
        android:layout_marginLeft="10dip" android:text="hello"
        android:gravity="center_vertical" android:layout_alignParentLeft="true"
        android:layout_toLeftOf="@+id/image"></TextView>
    <TextView android:textSize="14dip" android:layout_height="wrap_content"
        android:layout_width="fill_parent" android:id="@+id/txtViewDescription"
        android:layout_marginLeft="10dip" android:text="hello2"
        android:gravity="center_vertical" android:layout_below="@+id/txtViewTitle"
        android:layout_toLeftOf="@+id/image"></TextView>
</RelativeLayout>  

As you said you want to use it as a row in a ListView, I changed the hight of the parent layout to "wrap_content".
