Как прокрутить приложение для Android?
Я уже пробовал Scrollview, но он не работает.
Так что это мой MainActivity:
package com.example.myapplication2;
import android.content.DialogInterface;
import android.content.Intent;
import android.icu.text.IDNA;
import android.nfc.Tag;
import android.os.PersistableBundle;
import android.support.annotation.NonNull;
import android.support.design.widget.BottomNavigationView;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentTransaction;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.MenuItem;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;
import static com.example.myapplication2.R.id.*;
public class MainActivity extends AppCompatActivity implements BottomNavigationView.OnNavigationItemSelectedListener {
private boolean loadFragment(Fragment fragment){
if(fragment!=null){
getSupportFragmentManager()
.beginTransaction()
.replace(fragment_container, fragment)
.commit();
return true;
}
return false;
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
BottomNavigationView navigation = findViewById(R.id.bottomnav);
navigation.setOnNavigationItemSelectedListener(this);
getSupportFragmentManager().beginTransaction().replace(fragment_container, new Home_Screen()).commit();
}
@Override
public boolean onNavigationItemSelected(@NonNull MenuItem menuItem) {
Fragment fragment = null;
switch(menuItem.getItemId()){
case kontakt:
break;
case Termine:
fragment = new TermineFragment();
break;
case wilkommen:
fragment = new Home_Screen();
break;
}
return loadFragment(fragment);
}
}
А это мой XML-файл:

Что мне делать? Я хочу эти Cardviews в моем Scrollview.
