我的项目中有两个Activity。在我的DrawerActivity中，我添加了Navigation Drawer和其他活动，即TabActivity，我有片段列表。我试图在DrawerActivity中显示TabActivity的内容。 是可以这样做还是我遵循另一种方法。我是新手开发者，请帮帮我。

在你的代码中你应该这样做：
public void setupToolbar(){
// Initializing Toolbar and setting it as the actionbar
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
ImageView drawer_icon= (ImageView) findViewById(R.id.drawer_icon);
drawer_icon.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
if (!drawerLayout.isDrawerOpen(GravityCompat.END)) {
drawerLayout.openDrawer(GravityCompat.END);
}
}
});
}
public void setupTabs(){
tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(mViewPager);
}
public void setupDrawer(){
//Initializing NavigationView
navigationView = (NavigationView) findViewById(R.id.navigation_view);
// Initializing Drawer Layout and ActionBarToggle
drawerLayout = (DrawerLayout) findViewById(R.id.drawer);
ActionBarDrawerToggle actionBarDrawerToggle = new ActionBarDrawerToggle(this,drawerLayout,toolbar
,R.string.drawer_opened, R.string.drawer_closed){
@Override
public void onDrawerClosed(View drawerView) {
// Code here will be triggered once the drawer closes as we dont want anything to happen so we leave this blank
super.onDrawerClosed(drawerView);
}
@Override
public void onDrawerOpened(View drawerView) {
// Code here will be triggered once the drawer open as we dont want anything to happen so we leave this blank
super.onDrawerOpened(drawerView);
}
};
//Setting the actionbarToggle to drawer layout
drawerLayout.setDrawerListener(actionBarDrawerToggle);
//calling sync state is necessay or else your hamburger icon wont show up
// actionBarDrawerToggle.syncState();
}
public void tabListener(){
tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
@Override
public void onTabSelected(TabLayout.Tab tab) {
mViewPager.setCurrentItem(tab.getPosition());
if(tab.getPosition()==0){
NewsPage.newInstance(tab.getPosition());
}
else if(tab.getPosition()==1){
MainPage.newInstance(tab.getPosition());
}
else{
AnnouncementsPage.newInstance(tab.getPosition());
}
}
@Override
public void onTabUnselected(TabLayout.Tab tab) {
}
@Override
public void onTabReselected(TabLayout.Tab tab) {
}
});
}
public void drawerListener(){
//Setting Navigation View Item Selected Listener to handle the item click of the navigation menu
navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
// This method will trigger on item Click of navigation menu
@Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
Intent intent;
//Checking if the item is in checked state or not, if not make it in checked state
// if (menuItem.isChecked()) menuItem.setChecked(false);
// else menuItem.setChecked(true);
//Closing drawer on item click
drawerLayout.closeDrawers();
//Check to see which item was being clicked and perform appropriate action
switch (menuItem.getItemId()) {
//Replacing the main content with ContentFragment Which is our Inbox View;
case R.id.innovation_center:
MainActivity.position.setValue(MainActivity.CATEGORY,INNOVATION_CENTER_CATEGORY_NUMBER);
intent=new Intent(MainActivity.this,MainActionList.class);
startActivity(intent);
return true;
// For rest of the options we just show a toast on click
case R.id.about_university:
MainActivity.position.setValue(MainActivity.CATEGORY,ABOUT_UNIVERSITY_CATEGORY_NUMBER);
intent=new Intent(MainActivity.this,MainActionList.class);
startActivity(intent);
return true;
case R.id.contact_us:
intent=new Intent(MainActivity.this,ContactUs.class);
startActivity(intent);
return true;
default:
Toast.makeText(getApplicationContext(), "Somethings Wrong", Toast.LENGTH_SHORT).show();
return true;
}
}
});
}
public void setupPager(){
// Create the adapter that will return a fragment for each of the three
// primary sections of the activity.
mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());
// Set up the ViewPager with the sections adapter.
mViewPager = (ViewPager) findViewById(R.id.pager);
mViewPager.setAdapter(mSectionsPagerAdapter);
mViewPager.setCurrentItem(1);
}

如果要将导航抽屉添加到其他活动中，可以通过在TabActivity中扩展DrawerActivity来实现。 如需进一步参考，请查看此链接。
