横向滑动的GridView
思路:
GridView行数设置为一行,外面套一个HorizontalScrollView,代码中设置GridView宽度
xml代码
<HorizontalScrollView
android:layout_width="match_parent" android:layout_height="wrap_content" android:scrollbars="none" > <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="horizontal" > <GridView android:id="@+id/gv" android:layout_width="wrap_content" android:layout_height="wrap_content" > </GridView> </LinearLayout>
</HorizontalScrollView>
代码中设置
// 得到像素密度 DisplayMetrics outMetrics = new DisplayMetrics(); getActivity().getWindowManager().getDefaultDisplay() .getMetrics(outMetrics); float density = outMetrics.density; // 像素密度 ViewGroup.LayoutParams params = gridView.getLayoutParams(); int itemWidth = (int) (100 * density);// 默认item宽度为100 int spacingWidth = (int) (5 * density); params.width = (itemWidth + spacingWidth) * childCount + spacingWidth; gridView.setStretchMode(GridView.NO_STRETCH); // 设置为禁止拉伸模式 gridView.setNumColumns(childCount); gridView.setHorizontalSpacing(spacingWidth); gridView.setColumnWidth(itemWidth); gridView.setLayoutParams(params);
