GridView嵌套HorizontalScrollView，GridView布局参数设置

public void  horizontal_layout(GridView gridView ,int size) {
DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);
float density = dm.density;
int allWidth = (int) (110 * size * density);
int itemWidth = (int) (100 * density);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
allWidth, LinearLayout.LayoutParams.FILL_PARENT);
gridView.setLayoutParams(params);// 设置GirdView布局参数
gridView.setColumnWidth(itemWidth);// 列表项宽
gridView.setHorizontalSpacing(10);// 列表项水平间距
gridView.setStretchMode(GridView.NO_STRETCH);
gridView.setNumColumns(size);//总长度
}
