我的应用程序有问题，我目前正在实现选项卡导航，并且我想要一个导航抽屉。问题是我真的不知道如何正确地做到这一点，我使用了developers.android.com 上给出的示例，但它不适用于ViewPager。如果我在另一个应用程序中使用它，它会很好用。
我的 LogCat 是这样的：

我希望你能帮我解决这个问题。
谢谢！
编辑：我发现了问题，但我不知道如何替换 FrameLayout：
private void selectItem(int position) {
// update the main content by replacing fragments
Fragment fragment = new PlanetFragment();
Bundle args = new Bundle();
args.putInt(PlanetFragment.ARG_PLANET_NUMBER, position);
fragment.setArguments(args);
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction().replace(R.id.content_frame, fragment).commit();
// update selected item and title, then close the drawer
mDrawerList.setItemChecked(position, true);
setTitle(mPlanetTitles[position]);
mDrawerLayout.closeDrawer(mDrawerList);
}
另一个应用程序在主布局中有这个：
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout
android:id="@+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ffffff">
我的之前已经发布了代码。
