我想在图库视图中显示图像，它想使用其在 android 中的位置来聚焦于特定图像

  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);

尝试图库中的 setselection(position) 方法。请参阅http://developer.android.com/reference/android/widget/Gallery。 html

您尝试阅读文档吗？

public void setSelection (int position)

Since: API Level 1
Sets the currently selected item. To support accessibility subclasses that override this method must invoke the overriden super method first.
Parameters

position    Index (starting at 0) of the data item to be selected.

Did you try reading the documentation?
