Is it possible to use a navigation drawer in android but instead of updating fragments, i would like to switch between activities as my means of navigation within the app.
推荐答案
是的，它是可能的 - 这就是我所做的我的应用程序。我已经有一定数量的设立活动，而不是将它们全部转换为碎片，我想定制的导航抽屉跨越所有这些工作。不幸的是，这不是一个快速的解决方法，所以如果你有使用片段的选择，我会与该走了。但不管这里的我是如何做到的：
Yes it is possible - it's what I did for my app. I already had a number of activities set up, and rather than convert them all to fragments, I wanted to tailor the navigation drawer to work across all of them. Unfortunately, it's not a quick workaround, so if you have the option of using fragments, I would go with that. But regardless here's how I did it:
让我们说我有2个活动，这两个我想有导航抽屉。在layout.xml每个，我指定了 DrawerLayout 用适当的列表视图来握住我的导航选项。从本质上讲，导航抽屉是由我每次活动之间切换，给人的外观，它是坚持。为了让生活变得更加简单，我把设置导航抽屉，把他们自己的类所需的常用方法： NavigationDrawerSetup.java 。这样我的活动可以使用相同的定制适配器等
Let's say I have 2 activities, both of which I want to have the Navigation Drawer. In the layout.xml for each, I specified a DrawerLayout with the appropriate list view to hold my navigation options. Essentially, the Navigation drawer is made every time I switch between activities, giving the appearance that it is persisting. To make life a lot easier, I took the common methods required to set up the navigation drawer and put them in their own class: NavigationDrawerSetup.java. That way my activities can use the same custom adapter, etc.
在此 NavigationDrawerSetup.java 类，我有以下几点：
Within this NavigationDrawerSetup.java class, I have the following:
-
configureDrawer（）- 此设置的动作条， ActionBarDrawerToggle，和所需的听众 - 在我的自定义阵列适配器（填充列表内的导航选项）
- 的selectOptions（）方法，该方法
configureDrawer()- this sets up the ActionBar, ActionBarDrawerToggle, and the required listeners- My custom array adapter (to populate the navigation options within the list)
- The selectOptions() method, which
当您设置导航抽屉内的活动之一，您只需创建一个新的navigationDrawer对象，并传入所需的布局参数（如drawerLayout，ListView控件等）。然后你会打电话 confiugreDrawer（）：
When you set up the navigation drawer within one of your activities, you just create a new navigationDrawer object and pass in the required layout parameters (like the drawerLayout, listView etc). Then you'd call confiugreDrawer():
navigationDrawer = new NavigationDrawerSetup(mDrawerView, mDrawerLayout,
mDrawerList, actionBar, mNavOptions, currentActivity);
navigationDrawer.configureDrawer();
currentActivity 是因为导航抽屉被绑定到你的活动来传递。你将不得不使用它，当你设置了ActionBarDrawerToggle：
currentActivity is passed in since the navigation drawer is tied to the activity you are on. You will have to use it when you set up the ActionBarDrawerToggle:
mDrawerToggle = new ActionBarDrawerToggle(currentActivity, // host Activity
mDrawerLayout, /* DrawerLayout object */
R.drawable.ic_drawer, /* nav drawer image to replace 'Up' caret */
R.string.drawer_open, /* "open drawer" description for accessibility */
R.string.drawer_close /* "close drawer" description for accessibility */
)
seeting你arrayAdapter时，您还需要使用currentActivity：
You will also need to use currentActivity when seeting up your arrayAdapter:
至于如何通过导航抽屉活动之间进行切换，你可以建立新的意图你的选择信息中（）方法：
As for how to switch between activities via the navigation drawer, you can just set up new intents within your selectItem() method:
private void selectItem(int position) {
// Handle Navigation Options
Intent intent;
switch (position) {
case 0:
intent = new Intent(currentActivity, NewActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
currentActivity.startActivity(intent);
}
break;
case 1: // etc.
只要确保你的NewActivity也有抽屉式导航栏的设置，它应该显示。
Just make sure that your NewActivity also has the navigation drawer setup and it should display.
有一吨的东西，你可以做到这一点的方法来定制你自己的需要，但是这是我做到了的一般结构。希望这有助于！
There are a ton of things you can do to customize this method to your own needs, but this is the general structure of how I did it. Hope this helps!
