android:stretchMode="columnWidth"

<!--如何填满空余的位置，模拟器采用WVGA800*480，每排4列，有4＊100＋5＊3＝415，还余65px的空间，如果是columnWidth，则这剩余的65将分摊给4列，每列增加16/17px。如果采用SpacingWidth，则分摊给3个间隔空隙-->

其他笔记：

1.滚动gridview:

//滚动品牌栏privatevoidsmoothNextBrand(){floatpadding=getResources().getDimension(R.dimen.grid_brand_vspace);intoffset=Utils_Math.dip2px(this,padding);inth=mItemH_brand+offset;//+//mGridView_brand.getVerticalSpacing();//此方法api必须大于16mGridView_brand.smoothScrollBy(h,1000);mBrandAdapter.notifyDataSetChanged();}//滚动模板栏privatevoidsmoothNextMode(){finalinth=mItemH_mode;//+mGridView_mode.getVerticalSpacing();mGridView_mode.smoothScrollBy(h,1000);mModeAdapter.notifyDataSetChanged();}

2.监听滚动

privatevoidinitUI(){mGridView_mode.setOnScrollListener(this);}@OverridepublicvoidonScrollStateChanged(AbsListViewview,intscrollState){if(scrollState==OnScrollListener.SCROLL_STATE_IDLE){}}@OverridepublicvoidonScroll(AbsListViewview,intfirstVisibleItem,intvisibleItemCount,inttotalItemCount){}
