Android：ラジオボタンごとに選択/スワイブルできないタブを作る方法

Question

私のAndroidのアクティビティでは、私はradio button groupとtab layoutとviewpagerを使用しています。 2つのタブと2つのラジオボタンがあります。

• 最初のタブは、第1のイベントタブである取付タブ
• あります。

私は、最初のラジオボタンをチェックすると、ユーザは、最初のタブを見ることができたので、私は最初のタブを無効にする必要があり、私は必要な2つ目のラジオボタンを選択しuser.Ifための2番目のタブが表示されていません最初のタブを有効にし、ユーザーは最初のタブにアクセスすることができます。私はタブを削除したくない、私はそれを無効にしたいので、ユーザーがタブをスワイプまたはクリックしてアクセスすることはできません。

どうすればよいですか？以下は私のコードを表示するタブです。

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.create_asset); 
    //remaining code 
    viewPager2 = (ViewPager) findViewById(R.id.viewPager2); 
    setupViewPager2(viewPager2); 
    tabLayout2 = (TabLayout) findViewById(R.id.tab_layout2); 
    tabLayout2.setupWithViewPager(viewPager2);//setting tab over viewpager 
    rdbGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() { 
    } 
    }); 

     @Override 
     public void onCheckedChanged(RadioGroup group, int checkedId) { 

    //Implementing tab selected listener over tablayout 
    tabLayout2.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() { 
     @Override 
     public void onTabSelected(TabLayout.Tab tab) { 
      viewPager2.setCurrentItem(tab.getPosition());//setting current selected item over viewpager 
      switch (tab.getPosition()) { 
       case 0: 
        Log.e("TAG","TAB1"); 
        break; 
       case 1: 
        Log.e("TAG","TAB2"); 
        break; 
      } 
     } 

     @Override 
     public void onTabUnselected(TabLayout.Tab tab) { 
     } 

     @Override 
     public void onTabReselected(TabLayout.Tab tab) { 
     } 
    }); 
    } 

//Setting View Pager 
private void setupViewPager2(ViewPager viewPager) { 
    expAttList = new ArrayList<COAAccount>(); 
    adapter2 = new ViewPagerAdapter(getSupportFragmentManager()); 
    adapter2.addFrag(new AttachmentFragment("Attachments",expAttList,fontFamily), "Attachments"); 
    adapter2.addFrag(new EventFragment("Events",fontFamily), "Events"); 
    viewPager2.setAdapter(adapter2); 
} 


//View Pager fragments setting adapter class 
class ViewPagerAdapter extends FragmentPagerAdapter { 
    private final List<Fragment> mFragmentList = new ArrayList<>();//fragment arraylist 
    private final List<String> mFragmentTitleList = new ArrayList<>();//title arraylist 

    public ViewPagerAdapter(FragmentManager manager) { 
     super(manager); 
    } 

    @Override 
    public Fragment getItem(int position) { 
     return mFragmentList.get(position); 
    } 

    @Override 
    public int getCount() { 
     return mFragmentList.size(); 
    } 


    //adding fragments and title method 
    public void addFrag(Fragment fragment, String title) { 
     mFragmentList.add(fragment); 
     mFragmentTitleList.add(title); 
    } 

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

Answer 1

ですコード。これにXMLであなたのViewPagerを変更 ：以下

<yourPackage.NonSwipeableViewPager 
        android:id="@+id/pager" 
        android:layout_width="match_parent" 
        android:layout_height="400dp" 
        android:layout_below="@id/tab_layout"/> 

カスタムビューページャクラスです：

コードの下に、あなたの活動の使用中の今

public class NonSwipeableViewPager extends ViewPager { 
private boolean enabled; 

public NonSwipeableViewPager(Context context) { 
    super(context); 
    this.enabled = true; 
} 

public NonSwipeableViewPager(Context context, AttributeSet attrs) { 
    super(context, attrs); 
    this.enabled = true; 
} 

@Override 
public boolean onInterceptTouchEvent(MotionEvent event) { 
    if (this.enabled) { 
     return super.onInterceptTouchEvent(event); 
    } 

    return false; 
} 

@Override 
public boolean onTouchEvent(MotionEvent event) { 
    if (this.enabled) { 
     return super.onTouchEvent(event); 
    } 

    return false; 
} 

public void setPagingEnabled(boolean enabled) { 
    this.enabled = enabled; 
} 
} 

：

NonSwipeableViewPager viewPager = (NonSwipeableViewPager) findViewById(R.id.pager); 
//write code to set viewpager to the tablayout that u have already done.Use the same. 
rdbGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() { 
    @Override 
    public void onCheckedChanged(RadioGroup group, int checkedId) { 
     pos = rdbGroup.indexOfChild(findViewById(checkedId)); 
     LinearLayout tabStrip = ((LinearLayout)tabLayout.getChildAt(0)); 
     switch (pos) { 
      case 0: 
       viewPager.setCurrentItem(1); 
       viewPager.setPagingEnabled(false); 
       tabstrip.getChildAt(0).setClickable(false); 
       tabstrip.getChildAt(0).setEnabled(false); 
       break; 
      case 1: 
       viewPager.setCurrentItem(0); 
       viewPager.setPagingEnabled(true); 
       tabstrip.getChildAt(0).setClickable(true); 
       tabstrip.getChildAt(0).setEnabled(true); 
       break; 
      default: 
       //here add whatever you like 
       break; 
     } 
    } 
}); 

swicth条件を使用しますあなたの要件に応じて。

Answer 2

あなたはこの試すことができます：それはトリッキーone.Youがthis.BelowのカスタムViewPagerを使用する必要があります

ViewPager viewPager2; 
TabLayout tabLayout2; 
ViewPagerAdapter adapter2; 
RadioGroup rdbGroup; 
RadioButton rdb1, rdb2; 

LinearLayout tabstrip; 

int pos; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    //remaining code 
    viewPager2 = (ViewPager) findViewById(R.id.viewPager2); 
    setupViewPager2(viewPager2); 
    tabLayout2 = (TabLayout) findViewById(R.id.tab_layout2); 
    rdbGroup = (RadioGroup) findViewById(R.id.rdbGroup); 
    rdb1 = (RadioButton) findViewById(R.id.rdb1); 
    rdb2 = (RadioButton) findViewById(R.id.rdb2); 

    tabLayout2.setupWithViewPager(viewPager2);//setting tab over viewpager 

    //get position of already checked radiobutton 
    int radioButtonID = rdbGroup.getCheckedRadioButtonId(); 
    View radioButton = rdbGroup.findViewById(radioButtonID); 
    pos = rdbGroup.indexOfChild(radioButton); 

    tabstrip = (LinearLayout) tabLayout2.getChildAt(0); 

    //check which radiobutton is already checked and as per its pos disbale or enable the tabs as below 
    if (pos == 0) { 
     tabLayout2.getTabAt(1).select(); 
     tabstrip.getChildAt(0).setClickable(false); 
     tabstrip.getChildAt(0).setEnabled(false); 
    } else if (pos == 1) { 
     tabstrip.getChildAt(0).setClickable(true); 
     tabstrip.getChildAt(0).setEnabled(true); 
    } 

    rdbGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() { 
     @Override 
     public void onCheckedChanged(RadioGroup group, int checkedId) { 
      pos = rdbGroup.indexOfChild(findViewById(checkedId)); 

      switch (pos) { 
       case 0: 
        tabstrip.getChildAt(0).setClickable(false); 
        tabstrip.getChildAt(0).setEnabled(false); 
        break; 
       case 1: 
        tabstrip.getChildAt(0).setClickable(true); 
        tabstrip.getChildAt(0).setEnabled(true); 
        break; 
       default: 
        //here add whatever you like 
        tabstrip.getChildAt(0).setClickable(true); 
        tabstrip.getChildAt(0).setEnabled(true); 
        break; 
      } 
     } 
    }); 


    //Implementing tab selected listener over tablayout 
    tabLayout2.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {

      switch (tab.getPosition()) { 
       case 0: 
        Log.e("TAG", "TAB1"); 
        break; 
       case 1: 
        Log.e("TAG", "TAB2"); 
        break; 
      } 
     } 

     @Override

     } 

     @Override

    expAttList = new ArrayList<COAAccount>(); 
    adapter2 = new ViewPagerAdapter(getSupportFragmentManager());

    adapter2.addFrag(new EventFragment("Events", fontFamily), "Events"); 
    viewPager2.setAdapter(adapter2); 
} 


//View Pager fragments setting adapter class 
class ViewPagerAdapter extends FragmentPagerAdapter { 
    private final List<Fragment> mFragmentList = new ArrayList<>();//fragment arraylist 
    private final List<String> mFragmentTitleList = new ArrayList<>();//title arraylist 

    public ViewPagerAdapter(FragmentManager manager) { 
     super(manager); 
    } 

    @Override

     return mFragmentList.get(position); 
    } 

    @Override

    //adding fragments and title method
