메뉴 항목 내비게이션 창에서 클릭하여 조각을 호스팅하는 행위

Question

면책 조항 : 이것은 처음으로 조각을 사용하는 어려운 방법을 배우기 위해 작성한 첫 번째 앱이므로 내 코드가 여기 저기에 있습니다.

로드가 잘되는 탐색보기 안에 메뉴 항목이 있지만 메뉴 항목 클릭이 작동하지 않습니다. 그것은 단지 나를 쳐다 보지 못한다. 조각을 표시하기 위해 의도를 사용하고 싶습니다. 그리고 나는 많은 다른 옵션을 변경하고 시도하는 것으로부터 길을 잃습니다.

Answer 1

시도는 여기에서 pageone.java

당신의 onNavigationItemSelected의 내용에 변경 :

@Override 
public boolean onNavigationItemSelected(@NonNull MenuItem item) { 
    MenuItem itemWhiskey = (MenuItem) findViewById(R.id.itemWhiskey); 
    itemWhiskey.setOnMenuItemClickListener(new MenuItem.OnMenuItemClickListener() { 
     @Override 
     public boolean onMenuItemClick(MenuItem itemWhiskey) { 
      FragmentManager fm = getSupportFragmentManager(); 
      Fragment effectsFragment = fm.findFragmentById(R.id.frame_container2); 
      if (effectsFragment == null) { 
       effectsFragment = new WhiskeyFragment(); 
       fm.beginTransaction().add(R.id.frame_container2, effectsFragment).commit(); 
       getSupportActionBar().setTitle("Whiskey"); 
       itemWhiskey.setChecked(true); 
       mDrawerLayout.closeDrawers(); 
      } 
      return true; 
     } 
    }); 
    mDrawerLayout.closeDrawer(GravityCompat.START); 
    return true; 
} 

여기에 :

@Override 
public boolean onNavigationItemSelected(@NonNull MenuItem item) { 
    DrawerLayout mDrawerLayout = (DrawerLayout) findViewById(R.id.activity_pageone); // ID of your drawerLayout 
    int id = item.getItemId(); 

    switch (id) { 
     case R.id.menu1: // Change this as your menuitem in menu.xml. 
      // Your fragment code goes here.. 
      FragmentManager fm = getSupportFragmentManager(); 
      Fragment effectsFragment = fm.findFragmentById(R.id.frame_container2); 
      if (effectsFragment == null) { 
       effectsFragment = new WhiskeyFragment(); 
       fm.beginTransaction().add(R.id.frame_container2, effectsFragment).commit(); 
       getSupportActionBar().setTitle("Whiskey"); 
       itemWhiskey.setChecked(true); 
       mDrawerLayout.closeDrawers(); 
      } 
     break; 
     case R.id.menu2: // Change this as your menuitem in menu.xml. 
      // or Your fragment code goes here... 
     break; 
    } 
    mDrawerLayout.closeDrawer(GravityCompat.START, true); 
    return true; 
}
