我正在尝试按照tutorial关于如何创建导航抽屉,但我不想在用户从抽屉列表中选择项目后使用片段来显示新内容。解决这个问题的最佳方法是什么? 我正在使用不实现Fragments的API 10.
答案 0 :(得分:17)
首先,API 10可以通过包含DrawerLayout
的相同Android支持包访问片段。这已经存在了两年多了,如果您不熟悉Android过去两年的所有内容,那么您不应该尝试使用DrawerLayout
这样的新内容。
其次,DrawerLayout
与片段无关。引用the Web page that you linked to:
当用户选择抽屉列表中的项目时,系统会在给予setOnItemClickListener()的OnItemClickListener上调用onItemClick()。您在onItemClick()方法中执行的操作取决于您实现应用程序结构的方式。
如果你仔细阅读这两个句子,你会发现“片段”这两个词都没有出现。那是因为DrawerLayout
与片段无关。他们展示的示例代码使用片段,但这只是示例代码。
因此,欢迎您随意更新您的用户界面:
FragmentTransaction
,或setContentView()
,或答案 1 :(得分:1)
使用此代码
private void selectItem(int position) {
// Locate Position
switch (position) {
case 0:
startActivity(new Intent(this,TEST.class));
break;
答案 2 :(得分:1)
您也可以使用LayoutInflater类。
这是一个例子:
LinearLayout layoutToChange = (LinearLayout)findViewById(R.id.layout_to_change);
layoutToChange.removeAllViews();
LayoutInflater inflater = LayoutInflater.from(this);
LinearLayout newLayout = (LinearLayout)inflater.inflate(R.layout.new_layout, null);
layoutToChange.addView(newLayout);

没有片段的基本抽屉
