slidingmenu实现左侧滑

效果图

首先要导入slidingmenu的library文件，然后依赖，主页面和左菜单是两个Fragment

---

BaseFragment

让ContentFragment和LeftmenuFragment继承的基Fragment，实现代码的复用，避免两个子Fragment写重复的代码，initView方法使用抽象修饰，所以子Fragment必须实现。initData方法是可以不用实现的

public abstract class BaseFragment extends Fragment {    //得到activity      public Context context;    public BaseFragment() {        super();    }    @Override    public void onCreate(@Nullable Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        context=getActivity();//最终Fragment要绑定在MainActivity    }    @Nullable    @Override    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {        return initView();    }    //让孩子实现自己的视图，实现特有的效果     public abstract View initView();    @Override    public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {        super.onViewCreated(view, savedInstanceState);        initData();//数据绑定上面的视图    }    //如果自页面没有数据，联网请求数据，并且绑定到初始化initView的视图，有数据就直接绑定    public  void initData(){    }}

ContentFragment

主视图

public class ContentFragment extends BaseFragment {    private TextView textView;    @Override    public View initView() {        textView=new TextView(context);        LogUtil.d("初始化主视图View");        return textView;    }    @Override    public void initData() {        super.initData();        LogUtil.d("初始化主视图Data");        textView.setText("主视图");    }}

LeftmenuFragment

左菜单视图

public class LeftmenuFragment extends BaseFragment{    private TextView textView;    @Override    public View initView() {        textView=new TextView(context);        LogUtil.d("初始化左菜单View");        return textView;    }    @Override    public void initData() {        super.initData();        LogUtil.d("初始化左菜单Data");        textView.setText("左菜单");    }}

MainActivity

public class MainActivity extends SlidingFragmentActivity{    public static final String CONTENT_FRAGMENT = "content_fragment";    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        //设置主页面        setContentView(R.layout.main_activity);        //设置左侧菜单        setBehindContentView(R.layout.activity_leftmenu);        //        SlidingMenu slidingMenu=getSlidingMenu();        slidingMenu.setMode(SlidingMenu.LEFT);        slidingMenu.setTouchModeAbove(SlidingMenu.TOUCHMODE_FULLSCREEN);        //设置主页占据的宽度        slidingMenu.setBehindOffset(DensityUtil.dip2px(MainActivity.this,200));        //初始化Fragment        initFragment();    }    private void initFragment() {        FragmentManager fm=getSupportFragmentManager();        FragmentTransaction transaction=fm.beginTransaction();        transaction.replace(R.id.ll_main_content,new ContentFragment(),CONTENT_FRAGMENT);//主页面        transaction.replace(R.id.fl_leftmenu,new LeftmenuFragment(), "leftmenu_fragment");//左侧菜单        transaction.commit();    }}

transaction.replace（）是把Fragement栈的所有Fragment都清除再加入指定栈顶
