메뉴 항목에서 활동 열기

Question

의도를 사용하려고하지만 탐색 용 서랍에서 작동하지 않습니다. 네이티브 Menuitem (3 점)에서만 작동했지만 Navigation Drawer에서 사용하고 싶습니다.

아무도 도와 줄 수 있습니까?

@Override 
public boolean onOptionsItemSelected(MenuItem item){ 
    if (mToggle.onOptionsItemSelected(item)){ 
     return true; 
    } 
    return super.onOptionsItemSelected(item); 
} 



public boolean onNavigationItemSelected(MenuItem item) { 

    int id = item.getItemId(); 

    if (id == R.id.menu_one) { 
     Intent intent = new Intent(this, Activity1.class); 
     startActivity(intent); 
    } else if (id == R.id.menu_two) { 
     Intent intent = new Intent(this, Activity2.class); 
     startActivity(intent); 

    } 


    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawerLayout); 
    drawer.closeDrawer(GravityCompat.START); 
    return true; 
} 

Answer 1

대신 this 키워드를 사용하는 getApplicationContext()

Intent intent = new Intent(getApplicationContext(), Activity2.class); 
startActivity(intent); 

또는

startActivity(new Intent(Activity1.class, Activity2.class); 

Answer 2

확인 사용이

public class SetNavigationView { 
----------------------------- 
----------------------------- 
    private Context mcontext; 
----------------------------- 
----------------------------- 
    public SetNavigationView(final Activity activity, final NavigationView navigationView, final DrawerLayout drawer) { 
    this.mcontext = activity.getApplicationContext(); 
    ----------------------------- 
    ----------------------------- 
     /*TODO add menu item selection */ 
      NavigationView.OnNavigationItemSelectedListener item_click_listener = new NavigationView.OnNavigationItemSelectedListener() { 
       @Override 
       public boolean onNavigationItemSelected(@NonNull MenuItem item) { 
        if (id == R.id.nav_home) { 
         // Handle the home action 
         Intent intent = new Intent(mcontext, Home.class); 
         activity.startActivity(intent); 
        } 
        ----------------------------- 
        ----------------------------- 
        } 
    } 
    navigationView.setNavigationItemSelectedListener(item_click_listener); 
} 
}

이 시도 코드.

public boolean onNavigationItemSelected(MenuItem item) { 
    int id = item.getItemId(); 
    if (id == R.id.menu_one) { 
     startActivity(new Intent(MainActivity.this,Activity1.class)); 
     //MainActivity: Active activity 
    } else if (id == R.id.menu_two) { 
     startActivity(new Intent(MainActivity.this,Activity2.class)); 
     //MainActivity: Active activity 
    } 
    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawerLayout); 
    drawer.closeDrawer(GravityCompat.START); 
    return true; 
}
