好的，所以我对android开发还很陌生，我正在为我的老板开发一个项目，要求应用程序有一个导航抽屉。问题是所有页面都显示相同的内容（只应该在第一页上的内容）。我的问题是如何让所有页面都有不同的内容，我在哪里放这些内容？以下是来自activity_main的xml。
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.google.auditreport.MainActivity" >
<FrameLayout
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<!--
android:layout_gravity="start" tells DrawerLayout to treat
this as a sliding drawer on the left side for left-to-right
languages and on the right side for right-to-left languages.
If you're not building against API 17 or higher, use
android:layout_gravity="left" instead.
-->
<!--
The drawer is given a fixed width in dp and extends the full height of
the container.

答案 0 :(得分：1)
首先熟悉这里的示例应用http://developer.android.com/training/implementing-navigation/nav-drawer.html。
然后，为了帮助您，朝着正确的方向前进，XML不适合查看。在那里寻找类似BaseActivity.java的东西，你会发现像navDrawerItems.add(new NavDrawerItem...这样的想法，其中添加了所有菜单选项的列表。你应该能够找到像switch这样的东西运行这些项目以定义片段，然后使用FragmentManager来更改正在显示的片段。
以下是我的应用中的一个示例：
/**
* Diplaying fragment view for selected nav drawer list item
* */
public void displayView(int position) {
// update the main content by replacing fragments
Fragment fragment = null;
switch (position) {
case 0:
fragment = new ProfileFragment();
break;
case 1:
fragment = new ChartingFragment();
break;
case 2:
fragment = new DayHistoryFragment();
break;
case 3:
fragment = new WeekFragment();
break;
case 4:
fragment = new TemperatureFragment();
break;
case 5:
fragment = new CalendarFragment();
break;
case 6:
fragment = new WhatsHotFragment();
break;
case 7:
fragment = new SettingsFragment();
break;
case 8:
fragment = new DonateFragment();
break;
default:
break;
}
if (fragment != null) {
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction()
.replace(R.id.frame_container, fragment).commit();
// update selected item and title, then close the drawer
mDrawerList.setItemChecked(position, true);
mDrawerList.setSelection(position);
setTitle(navMenuTitles[position]);
mDrawerLayout.closeDrawer(mDrawerList);
} else {
// error in creating fragment
Log.e("MainActivity", "Error in creating fragment");
}
}
