Question

I am using this code for the image:

<ImageView android:src="@drawable/logo"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:layout_marginLeft="50dip"/>

I want the logo to be centered , it can be done by varying the Layout margin left value and check and position it, but is there any command to get it centered?

Try to use RelativeLayout:

  <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <ImageView 
        android:id="@+id/imageView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/app_logo"
        android:contentDescription="application_logo"
        android:layout_centerVertical="true"
        android:layout_centerHorizontal="true"
        />

</RelativeLayout>

If you want to use only horizonal alignment, only remove android:layout_centerVertical="true" from XML resource.
