java - 如何将 ScrollView 添加到抽屉导航

Question

我想将 ScrollView 添加到我的抽屉导航中，我首先尝试将线性布局作为 Scrollview 下的子项，但是当我打开 fragment 时，抽屉导航显示在我的 fragment 下方。我想让我的 fragment 保持不变，而抽屉导航现在确实显示在 fragment 后面，并且抽屉导航具有 ScrollView 。

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();
    }


}

我想要的主要内容滚动示例:

当主要内容可滚动时，它显示在第一个 fragment 下方

Answer 1

我认为你必须设置

<com.google.android.material.navigation.NavigationView
    ...
    android:fitsSystemWindows="true"
    android:isScrollContainer="true"
    ... />
