Gallery has default selected item is no 1 which is in center and left side is blank. Instead I want no 1 item should be at left and selected. for that i used following code,

MarginLayoutParams mlp = (MarginLayoutParams) myGallery.getLayoutParams();
        mlp.setMargins(-100, mlp.topMargin, mlp.rightMargin,
                mlp.bottomMargin);

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

    <ImageView android:layout_width="180px"
        android:layout_height="169px" android:id="@+id/imageView1"
        android:src="@drawable/gallary_each_bg" 
        ></ImageView>
