내가 Tabsrtip.setupwithviewpager을 을 사용 .When이 내 레이아웃 파일입니다 rosource 파일의 오류를 보여줍니다. 또는 애플리케이션이 불행하게도 중지되었습니다. tablayout.setupwithviewpager 을 사용했는데 오류도 표시됩니다. Beloy가 내 Java 파일입니다. ViewPager 어댑터

@Override 
    public CharSequence getPageTitle(int position) { 
     return tabText[position]; 
    } 
    @Override 
    public int getCount() { 
     return 2; 
    } 


    tabText = new String[]{ 
      "Tab 1", 
      "Tab 2" 
    }; 

프로그램 tabLayout에 탭을 추가 할 필요가 없습니다에 getPageTitle 기능을이 라인을

tabLayout = (TabLayout) findViewById(R.id.tabLayout); 
viewPager = (ViewPager) findViewById(R.id.pager); 
Pager adapter = new Pager(getSupportFragmentManager(),tabLayout.getTabCount()); 


viewPager.setAdapter(adapter); 
tabLayout .setupWithViewPager(viewPager); 

을 추가하고 우선하여 viewpager와

Answer 1

동기화하여 tablayout. 뷰 페이지와 동기화하면 getpageTitle에서 탭 이름을 선택합니다. 및 tabText

getCount

의 탭의 수는 사용자 Tablayout CHAGE 탭 아이콘 변경 탭

의 이름을 포함 문자열 배열이다. 페이지가 선택 또는 선택 해제 될 때 아이콘을 변경한다 addOnPageChangeListener

//Method to set up tab layout icon 
private void setUpTabIcon() { 
    for (int i = 0; i < mTabLayout.getTabCount(); i++) { 
     if (mTabLayout.getTabAt(i).isSelected()) 
      mTabLayout.getTabAt(i).setIcon(imageResId[i][1]); 
     else 
      mTabLayout.getTabAt(i).setIcon(imageResId[i][0]); 

    } 

} 

이 함수 onPageSelected 방법에있어서 그 기능을 사용한다. 2 상태의 아이콘을 사용하고 기본값은 1이고 하나는 눌렀습니다.

Answer 2

사용 : 귀하의 경우

viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout)); 
tabLayout.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() { 
     @Override 
     public void onTabSelected(TabLayout.Tab tab) { 
      viewPager.setCurrentItem(tab.getPosition()); 
     } 

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

     } 

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

     } 
    }); 

이 viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {... 은 잘못된 것입니다.
