我想在同一个活动中使用NavigationDrawer和ViewPager，但它无法正常工作。我正在关注developer google tutorial我希望有三个选项卡，如果选中它们，每个选项卡都将显示一个不同的ExpandableList。目前我得到的NavigationDrawer和ExpandableList工作正常，但TabBar和de ViewPager不管理滑动和点击事件。如何在Android中使用带有NavigationDrawer的ViewPager
任何人都可以帮助我吗？我一直在阅读和寻找年龄！
我的主要活动HomeActivity是这样的：
public class HomeActivity extends FragmentActivity implements ActionBar.TabListener{
// ExpandableList
private ArrayList<String> parentItems = new ArrayList<>();
private ArrayList<Object> childItems = new ArrayList<>();
// SlideMenu
private String[] mPlanetTitles;
private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
private CharSequence mDrawerTitle;
private CharSequence mTitle;
private ActionBarDrawerToggle mDrawerToggle;
// Declaraciones Pager
AppSectionsPagerAdapter mAppSectionsPagerAdapter;
ViewPager mViewPager;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
///// EXPANDABLELISTVIEW PART /////
ExpandableListView expandableList = (ExpandableListView) findViewById(R.id.expandableListView1);
expandableList.setGroupIndicator(null);
expandableList.setClickable(true);
setGroupParents();
setChildData();
MyExpandableAdapter adapter = new MyExpandableAdapter(parentItems, childItems);
adapter.setInflater((LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE), this);
expandableList.setAdapter(adapter);
expandableList.setOnChildClickListener(new ExpandableListView.OnChildClickListener() {
@Override
public boolean onChildClick(ExpandableListView parent, View v, int groupPosition, int childPosition, long id) {
return false;
}
});
/////// ACTIONBAR PART///////////
ActionBar mActionBar = getActionBar();
mActionBar.setDisplayShowHomeEnabled(false);
mActionBar.setDisplayShowTitleEnabled(false);
LayoutInflater mInflater = LayoutInflater.from(this);
View mCustomView = mInflater.inflate(R.layout.custom_actionbar, null);
TextView mTitleTextView = (TextView) mCustomView.findViewById(R.id.title_text);
mTitleTextView.setText("Título");
mActionBar.setCustomView(mCustomView);
mActionBar.setDisplayShowCustomEnabled(true);
/////// NAVIGATION DRAWER PART////////
mTitle = mDrawerTitle = getTitle();
mPlanetTitles = getResources().getStringArray(R.array.prueba_array);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList = (ListView) findViewById(R.id.left_drawer);
// set a custom shadow that overlays the main content when the drawer opens
mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);
// set up the drawer's list view with items and click listener
mDrawerList.setAdapter(new ArrayAdapter<String>(this,
R.layout.drawer_list_item, mPlanetTitles));
mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
// enable ActionBar app icon to behave as action to toggle nav drawer
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);
// ActionBarDrawerToggle ties together the the proper interactions
// between the sliding drawer and the action bar app icon

this, /* host Activity */

我已经使用你的代码，但膨胀其他布局，因为现在的问题是ExpandableListView。我无法在ViewPager中显示它，并且我不知道如何设置适配器的数据。 – juliocb92
其中是activity_home中的R.id.expandableListView1？ –
