This is my code for your perusal. Thank you in advance!
I have this code:
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.view.View;
import android.widget.CompoundButton;
import android.widget.ListView;
import java.util.ArrayList;
public class Main extends ActionBarActivity implements
android.widget.CompoundButton.OnCheckedChangeListener {
ListView lv;
ArrayList<Planet> planetList;
PlanetAdapter plAdapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
lv = (ListView) findViewById(R.id.listview);
displayPlanetList();
}
private void displayPlanetList() {
planetList = new ArrayList<Planet>();
planetList.add(new Planet("Margherita", 6, "€"));
planetList.add(new Planet("Diavola", 7,"€"));
planetList.add(new Planet("Bufalina", 5,"€"));
planetList.add(new Planet("Marinara", 5,"€"));
planetList.add(new Planet("Viennese", 4,"€"));
plAdapter = new PlanetAdapter(planetList, this);
lv.setAdapter(plAdapter);
}
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
int pos = lv.getPositionForView(buttonView);
if (pos != ListView.INVALID_POSITION) {
Planet p = planetList.get(pos);
p.setSelected(isChecked);
/*Toast.makeText(
this,
"Clicked on Planet: " + p.getName() + ". State: is "
+ isChecked, Toast.LENGTH_SHORT).show();*/
}
}
public void showResult(View v) {
String result = "Selected Product are :";
int totalAmount=0;
for (Planet p : plAdapter.getBox()) {
if (p.selected){
result += "\n" + p.name+" "+p.distance+"€"+"q.tà :"+p.getQuantità();
//if (p.quantità.equals("") && p.quantità.equals(null) ){
System.out.println("leggo questo record:"+p.name + " " + p.distance + " " + p.quantità );
System.out.println("leggo questo p.getquatità :"+p.quantità );
//}
//else{
System.out.println("leggo questo in p.quantità: "+p.getQuantità());
int quantitaInt= Integer.parseInt(p.getQuantità() );
totalAmount+=p.distance * quantitaInt;
//}
}
}
// Toast.makeText(this, result+"\n"+"Total Amount:="+totalAmount, Toast.LENGTH_LONG).show();
//Integer.toString(totalAmount);
Intent i = new Intent(Main.this, SecondActivity.class);
i.putExtra("NomeDati1", result);
i.putExtra("NomeDati2", String.valueOf(totalAmount));
startActivity(i);
}
}
AND this:
public class ScrollableTabsActivity extends AppCompatActivity {
private Toolbar toolbar;
private TabLayout tabLayout;
private ViewPager viewPager;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_scrollable_tabs);
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
viewPager = (ViewPager) findViewById(R.id.viewpager);
setupViewPager(viewPager);
tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(viewPager);
}
private void setupViewPager(ViewPager viewPager) {
ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
adapter.addFrag(new OneFragment(), "PIZZE");
adapter.addFrag(new TwoFragment(), "TWO");
adapter.addFrag(new ThreeFragment(), "THREE");
adapter.addFrag(new FourFragment(), "FOUR");

viewPager.setAdapter(adapter);
}
class ViewPagerAdapter extends FragmentPagerAdapter {
private final List<Fragment> mFragmentList = new ArrayList<>();
private final List<String> mFragmentTitleList = new ArrayList<>();
public ViewPagerAdapter(FragmentManager manager) {
super(manager);
}
@Override
public Fragment getItem(int position) {
return mFragmentList.get(position);
}
@Override
public int getCount() {
return mFragmentList.size();
}
public void addFrag(Fragment fragment, String title) {
mFragmentList.add(fragment);
mFragmentTitleList.add(title);
}
@Override
public CharSequence getPageTitle(int position) {
return mFragmentTitleList.get(position);
}
}
}
AND this:
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import info.androidhive.materialtabs.R;

// Required empty public constructor
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
return inflater.inflate(R.layout.main, container, false);
}
}
