Wie kann ich zu 3 Fragmenten in 3 Tabs unterschiedliche Daten hinzufügen?

Question

Ich möchte wissen, dass wie kann ich einige verschiedene Daten wie ein Array zu jedem Fragment hinzufügen, die in TabLayout sind? meine ich, dass fragment1 Show array1, fragment2 Show array2 und fragment3 zeigen array3

die unten ist mein Code für Tablayout:

public class PoshtibaniActivity extends AppCompatActivity { 

private Toolbar toolbar; 
private ViewPager mPager; 
private SlidingTabLayout mTabs; 
private TabLayout tabLayout; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_poshtibani); 
    toolbar = (Toolbar) findViewById(R.id.app_bar_empty); 
    //setSupportActionBar(toolbar); 
    toolbar.setTitle("پشتیبانی"); 
    setSupportActionBar(toolbar); 

    getSupportActionBar().setHomeButtonEnabled(true); 
    getSupportActionBar().setDisplayHomeAsUpEnabled(true); 

    mPager = (ViewPager) findViewById(R.id.pager); 
    setupViewPager(mPager); 
    mPager.setCurrentItem(2); 

    tabLayout = (TabLayout) findViewById(R.id.tabs); 
    tabLayout.setupWithViewPager(mPager); 

} 

private void setupViewPager(ViewPager viewPager) { 
    ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager()); 
    adapter.addFragment(new FragmentOne(), "پیامهای دریافتی"); 
    adapter.addFragment(new FragmentTwo(), "پیامهای ارسالی"); 
    adapter.addFragment(new FragmentThree(), "ارسال پیام"); 
    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 addFragment(Fragment fragment, String title) { 
     mFragmentList.add(fragment); 
     mFragmentTitleList.add(title); 
    } 

    @Override 
    public CharSequence getPageTitle(int position) { 
     return mFragmentTitleList.get(position); 
    } 
} 

Answer 1

Sie SetArguement für jedes Ihrer Fragmente verwenden sollten.

private void setupViewPager(ViewPager viewPager) { 
    ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager()); 
    adapter.addFragment(new FragmentOne(), "پیامهای دریافتی",MY_ARRAY_1,MY_SEC_ARRAY_1); 
    adapter.addFragment(new FragmentTwo(), "پیامهای ارسالی",MY_ARRAY_2,MY_SEC_ARRAY_2); 
    adapter.addFragment(new FragmentThree(), "ارسال پیام",MY_ARRAY_3,MY_SEC_ARRAY_3); 
    viewPager.setAdapter(adapter); 
} 

dann in Ihrem Adapter:

public void addFragment(Fragment fragment, String title,Object data,ArrayList<MY_DATA_MODEL> array2) { 
    Bundle mBundle=new Bundle(); 
    mBundle.put("dataArray",data); 
    mBundle.put("dataArray2",array2); 
    fragment.setArgument(mBundle); 
    mFragmentList.add(fragment); 
    mFragmentTitleList.add(title); 
} 

nun in jedem Ihres Fragmente, sollten Sie setArguments außer Kraft setzen und Ihre Daten aus Bündel dort.

Vergessen Sie nicht, Ihr Datenmodell parzellierbar zu machen, wenn Sie es bündeln und abstimmen möchten.

public class SamplePagerAdapter extends FragmentPagerAdapter { 


    String[] title = { 
    "stringA", 
    "stringB",
