ActionBarActivity 无法解析为类型

Question

行::

ActionBar actionBar = ((ActionBarActivity)getActivity()).getSupportActionBar();

我收到错误消息:: ActionBarActivity cannot be resolved to a type

我的 MainActivity

    public class ActLogin extends ActionBarActivity {

        String className;

        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);

            setContentView(R.layout.act_login);
            //set
            //Set the color for Actionbar
            getSupportActionBar().setBackgroundDrawable(new ColorDrawable(getResources().getColor(R.color.windhya_actionbar_color)));

            //Hide Appicon
            getSupportActionBar().setDisplayHomeAsUpEnabled(false);
            getSupportActionBar().setIcon(android.R.color.transparent);

            //First fragment should be mounted on oncreate of main activity
            if (savedInstanceState == null) {  

                Fragment newFragment = FrgLogin.newInstance();  
                FragmentTransaction ft = getSupportFragmentManager().beginTransaction();  
                ft.replace(R.id.container, newFragment).addToBackStack(FrgLogin.class.getSimpleName()).commit();  
            }

        }

您需要从 android.support.v7.app.ActionBarActivity 导入它。如包名所示，您需要 support-v7 包。
