我单击导航抽屉中的项目,它会将我重定向到另一个活动,但我单击的项目不会突出显示。您可以在下面的 GIF 中看到它。
MenuActivity.class
setContentView(R.layout.activity_menu);
Toolbar toolbar = findViewById(R.id.mytoolbar);
setSupportActionBar(toolbar);
Drawer(toolbar,MenuActivity.this,MenuActivity.this);
if (getSupportActionBar() != null) {
getSupportActionBar().setTitle("Аппараты");
}
无效抽屉:
public void Drawer(Toolbar toolbar, Context context, android.app.Activity activity){
DatabaseReference rootRef2 = FirebaseDatabase.getInstance().getReference();
DatabaseReference uidRef2 = rootRef2.child("users").child(getUid());
ValueEventListener valueEventListener2 = new ValueEventListener() {
@Override
public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
String email = dataSnapshot.child("account").getValue(String.class);
String Avatar = dataSnapshot.child("Avatar").getValue(String.class);
Long coinsAmount = dataSnapshot.child("coinsAmount").getValue(Long.class);
String coinsView = "Баланс: " + coinsAmount;
if (Avatar.equals("1")) {
avatar = (R.drawable.a1);
}
if (Avatar.equals("2")) {
avatar = (R.drawable.a2);
}
IProfile profile = new ProfileDrawerItem()
.withName(email)
.withEmail(coinsView)
.withIcon(avatar);
AccountHeader headerResult = new AccountHeaderBuilder()
.withActivity(activity)

如何使一切正常运行并像所有正常的应用程序一样?
我什至不知道如何解决它
