  public class MenuActionBar extends Activity {

@SuppressLint("NewApi")
@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    getActionBar().setBackgroundDrawable(new 
               ColorDrawable(Color.parseColor("#33B5E5"))); 

    int titleId = Resources.getSystem().getIdentifier("action_bar_title", "id", "android");
    TextView titleText = (TextView)findViewById(titleId);
    titleText.setTextColor(Color.parseColor("#ffffff"));
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // TODO Auto-generated method stub
     getMenuInflater().inflate(R.menu.main, menu);
        setMenuBackground();
        return true;

        @Override

            if ( name.equalsIgnoreCase( "com.android.internal.view.menu.IconMenuItemView" ) ) {
                try { // Ask our inflater to create the view  
                    LayoutInflater f = getLayoutInflater();  
                    final View view = f.createView( name, null, attrs );  
                    /* The background gets refreshed each time a new item is added the options menu.

                    new Handler().post( new Runnable() {  
                        public void run () {  
                            // sets the background color   
                            view.setBackgroundResource( R.color.menubg);
                            // sets the text color              
                            ((TextView) view).setTextColor(Color.WHITE);
                            // sets the text size              
                            ((TextView) view).setTextSize(18);
            }
                    } );  
                return view;
            }
        catch ( InflateException e ) {}
        catch ( ClassNotFoundException e ) {}  
    } 
            return null;
        }});

}
 }

我在这三行中有错误

getLayoutInflater().setFactory( new Factory() { 

        @Override
        public View onCreateView(String name, Context context,AttributeSet attrs)

new Factory()要求再次创建onCreateView，即使它是存在的并且R.menu.main说它无法解决主要问题最后一个错误Context和AttributeSet问我创建它们的类。

将品牌颜色添加到操作栏的最佳方法是创建自定义样式。一个很好的工具是Action Bar Style Generator。

ActionBarMenu更改颜色错误？
