import java.net.URI;

public class Sobre extends AppCompatActivity {
    private AppBarConfiguration mAppBarConfiguration;
    private Button btnreceita, btndespesa;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_sobre);
        Button btnreceita = (Button) findViewById(R.id.btnreceita);
        DrawerLayout drawer = findViewById(R.id.drawer_layout);
        NavigationView navigationView = findViewById(R.id.nav_view);

        btndespesa.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent = new Intent(getApplicationContext(), Sobre.class);
                startActivity(intent);
                // NÃO DÁ ERRO ALGUM, MAS O BUTTON NÃO CHAMA A PRÓXIMA TELA
                // O BUTTON ESTÁ DENTRO DE UM POPUP
            }
        });

        // Passing each menu ID as a set of Ids because each
        // menu should be considered as top level destinations.

    }
}

Answer 1

The right thing would be:

Intent intent = new Intent(getApplicationContext(), Sobre.class);
startActivity(intent);

Where you would pass within the relatives the context of the application, in case getApplicationContext() and the destination, as: destination.class;

You have put the same Activity that is the button as destination, so it will not work even.

Answer 2

Hello, I don’t understand why you are calling your own Activity being the one already active. The Intent function serves to open a new activity, example:

Intent Intent = new Intent(Mainactivity.this, Main2activity.class); startActivity(i);
