我想将ScrollView添加到我的导航抽屉中，我首先尝试将线性布局作为滚动视图下的子项，但是当我打开片段时，导航抽屉显示在我的片段下。我想使片段保持不变，而导航抽屉现在确实显示在片段的后面，并且导航抽屉具有滚动视图。
抽屉代码：
public class drawer_home extends AppCompatactivity implements NavigationView.OnNavigationItemSelectedListener {
private DrawerLayout drawer;
Toolbar toolbar;
TextView mStartDate,mEndDate,mPlan,mDays;
FirebaseAuth firebaseAuth;
FirebaseUser user;
FirebaseDatabase firebaseDatabase;
DatabaseReference databaseReference;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_drawer_home);
toolbar = findViewById(R.id.tb);
mStartDate = findViewById(R.id.startDateTV);
mEndDate = findViewById(R.id.endDateTV);
mPlan = findViewById(R.id.planTV);
mDays = findViewById(R.id.daysTV);
setSupportactionBar(toolbar);
/*TextView textView = (TextView)toolbar.findViewById(R.id.toolbartv);
textView.setText("No Excusas");
getSupportactionBar().setDisplayShowTitleEnabled(false);*/
drawer = findViewById(R.id.drawer_layout);
NavigationView navigationView = findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
actionbardrawertoggle toggle = new actionbardrawertoggle(this,drawer,toolbar,R.string.navigation_drawer_open,R.string.navigation_drawer_close);
drawer.addDrawerListener(toggle);
toggle.syncState();
if(savedInstanceState == null) {
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,new androidx.fragment.app.Fragment()).commit();
navigationView.setCheckedItem(R.id.nav_homeMain);
}
firebaseAuth = FirebaseAuth.getInstance();
user = firebaseAuth.getcurrentUser();
firebaseDatabase = FirebaseDatabase.getInstance();
databaseReference = firebaseDatabase.getReference("Users");
Query query = databaseReference.orderByChild("email").equalTo(user.getEmail());
query.addValueEventListener(new ValueEventListener() {
@Override
public void onDataChange(@NonNull Datasnapshot datasnapshot) {
//checkc until requiered data get
for (Datasnapshot ds : datasnapshot.getchildren()) {
String startdate = "Fecha de Inicio = " + ds.child("Start Date").getvalue();
String enddate = "Fecha de Salida = " + ds.child("End Date").getvalue();
String plan = "Plan = " + ds.child("Plan").getvalue();
String days = "Tu plan acaba en " + ds.child("Days Left").getvalue() +" dias ";
mStartDate.setText(startdate);
mEndDate.setText(enddate);
mPlan.setText(plan);
mDays.setText(days);
}
}
@Override
public void onCancelled(@NonNull DatabaseError databaseError) {
}
});
}
@Override
public boolean onNavigationItemSelected(@NonNull MenuItem item) {
switch (item.getItemId()) {
case R.id.nav_homeMain:
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,new androidx.fragment.app.Fragment()).commit();
break;
case R.id.nav_qr:
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,new QRcodeFragment()).commit();
break;
case R.id.nav_profile:
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,new UserProfile()).commit();
break;
case R.id.nav_order:
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,new Ordersactivity()).commit();
break;
case R.id.nav_nutrition:
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,new Nutritionactivity()).commit();
break;
case R.id.nav_chat:
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,new Contactactivity()).commit();
break;
case R.id.nav_coach:
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,new Coachesactivity()).commit();
break;
case R.id.nav_information:
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,new AboutUsactivity()).commit();
break;
}
drawer.closeDrawer(GravityCompat.START);
return true;
}
@Override
public void onBackpressed() {
if (drawer.isDrawerOpen(GravityCompat.START)) {
drawer.closeDrawer(GravityCompat.START);
} else {
super.onBackpressed();
}
}
}
