如何在android中将多媒体资料集中到特定位置？

我想在gallery视图中显示图像，它想使用android中的位置聚焦到特定的图像

  SimpleAdapter adapter1 = new  SimpleAdapter(ShowingGalleryActivity.this,arrList1, R.layout.showinggalleryview, new String[]{"image","company"},
                    new int[]{R.id.showinggalleryview_goggle_iv,R.id.showinggalleryview_companyname_tv}
                    );
            mGallery.setDescendantFocusability(position);
            mGallery.setAdapter(adapter1);

在多媒体资料中尝试setselection（position）方法。参考

Since: API Level 1
