내비게이션 서랍 열기 창 닫기가 부드럽게 작동하지 않음

Question

This is my gif of problem. 내비게이션 서랍을 사용 중이며 아래 코드와 같이 일부 코드를 작성했지만 창 닫기 및 열기가 원활하게 수행 할 수 없습니다.

무엇을 어떻게해야이 부드럽게 만들기 :

이 내 코드?

Answer 1

그 때마다 한 번 한 번에 정의이 코드를 사용할 필요가 없습니다 코드 사용 때마다 : -

가

fragmentTransaction.replace(R.id.viewpager, desiredTutor).commit(); 

이 방법을 만들기를 -

public static void showFragment(Fragment fragment, String Tag) { 
    FragmentManager manager = activity.getSupportFragmentManager(); 
    FragmentTransaction transcation = manager.beginTransaction(); 
    transcation.replace(R.id.viewpager, fragment, Tag); 
    transcation.addToBackStack(Tag); 
    transcation.commit(); 

} 

및이를 사용 : -

switch (item.getItemId()) 
    { 
    case R.id.desired_tutor: 
    showFragment(new DesiredTutor(), ""); 
    break; 
    case R.id.payment_options: 
    showFragment(new BuyCredits(), ""); 
    break; 
    } 

Answer 2

DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout); 
    drawer.closeDrawer(GravityCompat.START); 

매번 시작합니다. 그것의 잘못. 한 번만 초기화하고 해당 객체를 사용하여 서랍을 열고 닫습니다. 선택한 리스너에서 해당 코드를 제거하고 Oncreate에 넣어 한 번 초기화하십시오. 코드 아래

사용은 완벽 만들려면 :

@Override 
    protected void onPostCreate(Bundle savedInstanceState) { 
     super.onPostCreate(savedInstanceState); 
     toggle.syncState(); 
    } 


ActionBarDrawerToggle toggle; 

toggle = new ActionBarDrawerToggle(this, mDrawerLayout, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close) { 
       @Override 
       public void onDrawerOpened(View drawerView) { 
        super.onDrawerOpened(drawerView); 
        invalidateOptionsMenu(); 
       } 

       @Override 
       public void onDrawerClosed(View drawerView) { 
        super.onDrawerClosed(drawerView); 
        invalidateOptionsMenu(); 
       } 
      }; 


mDrawerLayout.setDrawerListener(toggle);
