关键代码

    /**     * 设置GridView的宽度     *     * @param defaultColumns 设置列数 4     * @param defaultRows    设置行数 2     */    private void setGridViewValue(GridView gridView, int postion, int defaultColumns, int defaultRows) {        int count = recomGameAdapter.getCount();        gridView.setAdapter(recomGameAdapterList.get(postion));        int columns = 0;        if (count >= 8) {           //当count大于8时  如下排列           //| 1 | 3 | 5 | 7 |           //| 2 | 4 | 6 | 8 |            columns = (count % 2 == 0) ? count / 2 : count / 2 + 1;        } else {           //当count小于于8时  如下排列           //| 1 | 2 | 3 | 4 |           //| 5 | 6 | 7 | 8 |            columns = (count % defaultRows == 0) ? count / defaultRows : count / defaultRows + 1;            if (columns < defaultColumns) {                columns = defaultColumns;            }        }        int columnWidth = (dm.widthPixels - mContext.getResources().getDimensionPixelOffset(R.dimen.home_common_margin) * 2) / defaultColumns;        RelativeLayout.LayoutParams params =                new RelativeLayout.LayoutParams                        (columns * columnWidth, RelativeLayout.LayoutParams.WRAP_CONTENT);        gridView.setLayoutParams(params);        gridView.setColumnWidth(columnWidth);        // gridView.setHorizontalSpacing(hSpacing);        gridView.setStretchMode(GridView.NO_STRETCH);        gridView.setNumColumns(columns);    }
