我在一个使用表格的应用程序上工作。 在肖像上, 它有两列, 而不是风景三列。 我知道您可以使用 / res/ lay out- land 文件夹来改变视图, 但然后重置未保存的数据 。 除了使用 / res/ layout- land/ mylayout. xml 外, 还有其它选项吗?
如果您想要使用特定的文件夹( 类似 < code> lay out- land ), 您可以用 < code> TableLayoot 制作包含三列( 全部) 的单一版式文件, 然后根据当前电话方向隐藏/ 隐藏其中一列 。 在 < code> onCreate 方法中, 如果方向设置为 < code > landscape / < code> > /portrait < /code >, 则会显示/ disappen :
TableLayout tl = (TableLayout) findViewById(R.id.tableLayout1);
if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE) {
// make the column appear, we re in landscape orientation
tl.setColumnCollapsed(2, false);
} else {
tl.setColumnCollapsed(2, true);
}
我不知道你想用这个实现什么, 活动仍然会像往常一样 重新创造 当它转动的电话。
