他の回答と記事を確認しました。しかし、私が探しているものを見つけることができませんでした。私は何かが足りないかもしれない。別のrecyclerviewフラグメントの特定のアイテムをクリックしてrecyclerviewフラグメントをロードします。タブ付きフラグメントをクリックしますか?

  1. FragmentHome(表1)、
  2. FragmentTwo(表2)、
  3. FragmentThree(表3):

    私は3つの断片を含んタブ活性を有します。

ここで、HomeFragmentの 特定のアイテムをクリックすると別のFragment( "FragmentAnother")をロードします。 「HomeFragment」の「5番目のアイテム」(Recyclerviewフラグメント)をクリックすると、「FragmentAnother」(RecyclerViewFragment)がロードされます。また、HomeFragmentの特定のアイテムに対して特定のdetailViewをロードしたいとします。これを達成する方法は?

    // Create the adapter that will return a fragment for each of the three 
    // primary sections of the activity. 
    mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager()); 

    // Set up the ViewPager with the sections adapter. 
    mViewPager = (ViewPager) findViewById(R.id.container); 
    mViewPager.setAdapter(mSectionsPagerAdapter); 

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

    mViewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout)); 
    tabLayout.addOnTabSelectedListener(new TabLayout.ViewPagerOnTabSelectedListener(mViewPager));

私は質問権を持っている場合。

"FragmentHome.java"に以下のようなフラグメントを追加しようとしましたか? RecyclerviewアダプタでToastを表示している場所でこのコードを使用します。上記のコード

//Load another fragment on Click a card 
     holder.homeListCardViewRelativeLayout.setOnClickListener(new 
    View.OnClickListener() { 
      @Override 
      public void onClick(View view) { 
       FragmentTransaction fragmentTransaction=getChildFragmentManager().beginTransaction(); 
     fragmentTransaction.add(R.id.relativeLayout,new DetailFragment()); 
     fragmentTransaction.commit(); 
      } 
     }); 

詳細はHereを参照してください あなたの「FragmentHome.java」にフラグメントを追加します。

1つのフラグメントから別のフラグメントにデータを転送する場合は、Here
