如何在Android中将图库聚焦到特定位置？

Question

我想在图库视图中显示图像，想要使用其在android中的位置聚焦到特定图像

  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);

Answer 1

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

Answer 2

您是否尝试阅读文档？

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
