        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mContext = this;
        setUpMenu();
        if( savedInstanceState == null )
            changeFragment(new HomeFragment());
    }

    @Override

        resideMenu.closeMenu();
    }

        resideMenu.attachToActivity(this);
        resideMenu.setMenuListener(menuListener);
        //valid scale factor is between 0.0f and 1.0f. leftmenu'width is 150dip. 
        resideMenu.setScaleValue(0.6f);

        // create menu items;

        resideMenu.addMenuItem(itemHome, ResideMenu.DIRECTION_RIGHT);
        resideMenu.addMenuItem(itemIdentification, ResideMenu.DIRECTION_RIGHT);
        resideMenu.addMenuItem(itemRecent, ResideMenu.DIRECTION_RIGHT);

    }

    private ResideMenu.OnMenuListener menuListener = new ResideMenu.OnMenuListener() {
        @Override
        public void openMenu() {
            Toast.makeText(mContext, "Menu is opened!", Toast.LENGTH_SHORT).show();
        }

        @Override

            Toast.makeText(mContext, "Menu is closed!", Toast.LENGTH_SHORT).show();

非常感谢兄弟们

Answer 1

大多数情况下，问题是班级冲突/不是最新的。这些是我现在可以想到的选择。

检查项目构建路径
清洁项目
如果您确实使用支持库，请将其删除，然后重新添加。
重启eclipse / android studio
