问题:

For my academic project, I want create an application with 4 tabs. The first one will show recent games added to a list, the second one will be a search form, the third will show the search result, and the last one will show the details. I currently have created the code for TabView and the 4 tabs. The problem is that I want to perform a search to get the items I have in a list which meet the search criteria on fragment 2, but I don't know how to pass the data from fragment 2 (textView data and spinner) to fragment 3. My code is the following:

MainActivity.java:

回答1:

Try this

pass value between two fragment using bundle

import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;

public class TabPagerAdapter extends FragmentPagerAdapter{

int tabCount;

 public TabPagerAdapter(FragmentManager fm, int numberOfTabs) {
super(fm);
this.tabCount = numberOfTabs;
}

 @Override
public Fragment getItem(int position) {
switch (position) {
    case 0:
        return  new HomeScreenFragment();
    case 1:
        return new SearchFormFragment();
    case 2:
       Fragment fragment = new SearchResultsFragment()
     Bundle args = new Bundle();
     args.putString("Key", "Value");
     fragment.setArguments(args);
        return fragment;

    case 3:
        return new DetailsScreenFragment();
    default:
        return null;
   }
}

    @Override
     public int getCount() {

   return tabCount;

   }
   }

in your onCreateView(....) of SearchResultsFragment

 String value = getArguments().getString("Key");

 public class SearchResultsFragment extends Fragment {

TextView infoTextView;
ListView listViewGames;

  public SearchResultsFragment() {
   // Required empty public constructor
 }


  @Override
  public View onCreateView(LayoutInflater inflater, ViewGroup container,
                     Bundle savedInstanceState) {

   View searchResultsView = 
  inflater.inflate(R.layout.fragment_search_results, container, false);
    String value = getArguments().getString("Key");


   return searchResultsView;
 }
 private void findViews(){

 infoTextView = getActivity().findViewById(R.id.info_textView);
listViewGames = getActivity().findViewById(R.id.games_listView);
 }
 }

hop its help you

There are many ways you can pass objects/values between fragments. In your case, the simplest solution would be to delegate those values to the holding Activity i.e MainActivity.

MainActivity:

import android.os.Bundle;
import android.support.design.widget.FloatingActionButton;
import android.support.design.widget.Snackbar;
import android.support.design.widget.TabLayout;
import android.view.MenuInflater;
import android.view.View;
import android.support.design.widget.NavigationView;
import android.support.v4.view.GravityCompat;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.ActionBarDrawerToggle;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.Menu;
import android.view.MenuItem;
import android.support.v4.view.PagerAdapter;
import android.support.v4.view.ViewPager;
import android.widget.Button;
import android.widget.Toast;


public class MainActivity extends AppCompatActivity
    implements NavigationView.OnNavigationItemSelectedListener {
//these will hold your values
String filterGameTitle;
int filterGenreId;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);


    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);

    fab.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)

You can use interface to send your search string to your activity from fragment 2, and from their you can call all methods in your fragment 3 as fragment3 object will be available to you in your activity, you can make performSearch() in your fragment3 and call it from your activity. Alternatively you can use something like event bus to avoid the boiler plate code needed to setup interface.

Have a look at this event bus repo https://github.com/greenrobot/EventBus Register event bus where you want the search string, in your case register the event bus in Fragment3 like this

  @Override
 public void onStart() {
 super.onStart();
 EventBus.getDefault().register(this);
 }

 @Override
 public void onStop() {
 super.onStop();
 EventBus.getDefault().unregister(this);
 }

In your Fragment 3 create a function like this

    @Subscribe
public void onSearchEvent(String searchString){
 //you will get your search string here
}

Now comeback to fragment2 from where you want to send the searchString, you have to put below code from where you want to send searchString, and this posted searchString will be received by fragment 3 in its onSearchEvent method

EventBus.getDefault().post(searchString);
