Question

단순히 webview 및 mDrawer 슬라이드 메뉴를 사용하여 앱을 빌드했습니다. 그러나 그것이> 3 android에서 작동하지 않는 것을보고 난 후에 지원 라이브러리를 추가하고 약간의 변경을가했지만 여전히 작동하지 않습니다. 는 여기에 내가 getSupportActionBar에 getActionBar를()() 변경을 시도

코드입니다하지만 난 다음 오류가있어 : 방법 getSupportActionBar는() 형식의 새로운 ActionBarDrawerToggle() {}

Answer 1

, 당신은 MainActivity 대신 FragmentActivity의 ActionBarActivity을 확장해야한다. 개발자에서 촬영 안내 :

When using the support library, you can add the action bar to the top of your activity window by extending the ActionBarActivity class and setting the activity theme to Theme.AppCompat or a similar theme.

을 그런 다음() 대신 getActionBar의 작업 표시 줄을 얻을 수 getSupportActionBar()를 사용합니다;
