废话不多说，直接附代码：

分包如下：

View层

ISortView接口层

public interface ISortView {    // 展示左侧数据    void ShowLeftData(LeftBean leftBean);    // 展示右侧数据    void ShowRightData(RightBean rightBean);}

MyGridView（这个类用于修改GridView的高度，可随内容长度而增高）

public class MyGridView extends GridView {    public MyGridView(Context paramContext, AttributeSet paramAttributeSet) {        super(paramContext, paramAttributeSet);    }    @Override    public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {        //makeMeasureSpec根据提供的大小值和模式创建一个测量值(格式)        int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,                MeasureSpec.AT_MOST);        super.onMeasure(widthMeasureSpec, expandSpec);    }}

SortFragment

public class SortFragment extends Fragment implements ISortView {    SortPresenter presenter;    LeftAdapter leftAdapter;    @BindView(R.id.sort_left_listview)    ListView sortLeftListview;    Unbinder unbinder;    @BindView(R.id.sort_right_listview)    ListView sortRightListview;    RightAdapter right_adapter;    private boolean isLogin;    @Nullable    @Override    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {        View view = inflater.inflate(R.layout.sort, null);        init();        unbinder = ButterKnife.bind(this, view);        return view;    }    private void init() {                          presenter = new SortPresenter(this);        /*初始化 默认展示左侧数据*/            presenter.GetData();            }    @Override    public void onResume() {        super.onResume();                    presenter = new SortPresenter(this);        /*初始化 默认展示左侧数据*/            presenter.GetData();           }    @Override    public void onDestroyView() {        super.onDestroyView();        unbinder.unbind();    }    @Override    public void ShowLeftData(LeftBean leftBean) {        /*配置左侧适配器你*/        leftAdapter = new LeftAdapter(leftBean, getActivity());        sortLeftListview.setAdapter(leftAdapter);        /*左侧的监听事件*/        leftClick();    }    @Override    public void ShowRightData(RightBean rightBean) {        /*展示右侧数据*/        right_adapter = new RightAdapter(rightBean, getActivity());        sortRightListview.setAdapter(right_adapter);        /*右侧条目的点击事件*/        right_adapter.GetItemData(new RightAdapter.GetItemData() {            @Override            public void getItemData(String name, String pscid) {                ToastUtil.show(getActivity(), "--" + name + "." + pscid, 2000);            }        });    }    private void leftClick() {        leftAdapter.setClickName(new LeftAdapter.ClickName() {            @Override            public void Clickname(int cid) {                /*请求右侧数据*/                presenter.GetRightData(cid);            }        });    }}

Model层

public interface ISortModel {    // 请求数据的接口    void GetData();    // 请求右侧数据的接口    void GetRightData(int cid);}

public class SortModel implements ISortModel {    // 定义接口 用于保存数据    LeftBean bean;    // 保存右侧数据    RightBean rightBean;    public interface OnLeftFinish {        void onFinish(LeftBean bean);    }    private OnLeftFinish onLeftfinish;    public SortModel(OnLeftFinish onLeftfinish, OnRightFinish onrightfinish) {        this.onLeftfinish = onLeftfinish;        this.onrightfinish = onrightfinish;    }    public interface OnRightFinish {        void onRightFinish(RightBean bean);    }    private OnRightFinish onrightfinish;    @Override    public void GetData() {        Observable<LeftBean> leftData = SortLeftRetroFactory.getInstance().getLeftData(Field.SORT_LEFT_PATH);        leftData.subscribeOn(Schedulers.io())                .observeOn(AndroidSchedulers.mainThread())                .subscribe(new Subscriber<LeftBean>() {                    @Override                    public void onCompleted() {                        Log.d("sort", "onCompleted: ");                    }                    @Override                    public void onError(Throwable e) {                        Log.d("sort", "onError: ");                        e.printStackTrace();                    }                    @Override                    public void onNext(LeftBean leftBean) {                        Log.d("sort", "onNext: " + leftBean.getMsg());                        bean = leftBean;                        onLeftfinish.onFinish(bean);                    }                });    }    @Override    public void GetRightData(int cid) {        HashMap<String,String> map = new HashMap<>();        map.put("cid",cid+"");        final Observable<RightBean> rightData = RightRetroFactory.getInstance().getRightData(Field.SORT_RIGHT_PATH, map);        rightData.subscribeOn(Schedulers.io())                .observeOn(AndroidSchedulers.mainThread())                .subscribe(new Subscriber<RightBean>() {                    @Override                    public void onCompleted() {                        Log.d("sort", "onCompleted: ");                    }                    @Override                    public void onError(Throwable e) {                        Log.d("sort", "onError: ");                        e.printStackTrace();                    }                    @Override                    public void onNext(RightBean bean) {                        Log.d("sort", "onNextRight: "+bean.getData().get(0).getName()+"--");                        rightBean = bean;                        onrightfinish.onRightFinish(rightBean);                    }                });    }}

Presenter层

public class SortPresenter implements SortModel.OnLeftFinish, SortModel.OnRightFinish {    private final ISortView iSortView;    private final SortModel sortModel;    public SortPresenter(ISortView iSortView) {        this.iSortView = iSortView;        sortModel = new SortModel(this,this);    }    @Override    public void onFinish(LeftBean bean) {        iSortView.ShowLeftData(bean);    }    public void GetData(){        sortModel.GetData();    }    public void GetRightData(int cid){        sortModel.GetRightData(cid);    }    @Override    public void onRightFinish(RightBean bean) {        iSortView.ShowRightData(bean);    }}

java代码就上面那些，下来就是xml布局文件(听说大牛都比较懒)

Main布局：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="horizontal">    <ListView        android:id="@+id/sort_left_listview"        android:layout_width="match_parent"        android:layout_height="match_parent"        android:layout_weight="2"></ListView>    <ListView        android:id="@+id/sort_right_listview"        android:layout_width="match_parent"        android:layout_height="match_parent"        android:layout_weight="1"></ListView></LinearLayout>

sort_left_item布局

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:layout_margin="20dp"    android:orientation="vertical">    <TextView        android:background="@drawable/class_item_selector"        android:id="@+id/sort_left_tv"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:padding="20dp"        android:text="左侧文字"        android:textSize="30sp"        android:textStyle="bold" /></LinearLayout>

sort_right_grid_item布局

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:fresco="http://schemas.android.com/apk/res-auto"    android:layout_width="match_parent"    android:layout_height="wrap_content"    android:orientation="vertical">    <TextView        android:id="@+id/sort_right_grid_item_tv"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_gravity="center_horizontal"        android:text="文字"        android:textSize="20sp" />    <com.facebook.drawee.view.SimpleDraweeView        android:id="@+id/sort_right_grid_item_img"        android:layout_width="60dp"        android:layout_height="60dp"        android:layout_gravity="center_horizontal"        fresco:placeholderImage="@mipmap/ic_launcher" /></LinearLayout>

sort_right_item布局

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical">    <LinearLayout        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:orientation="horizontal">        <ImageView            android:layout_width="10dp"            android:layout_height="30dp"            android:layout_marginLeft="5dp"            android:layout_marginRight="10dp"            android:src="@color/red" />        <TextView            android:id="@+id/sort_right_title"            android:layout_width="match_parent"            android:layout_height="wrap_content"            android:text="测试"            android:textSize="24sp"            android:textStyle="bold" />    </LinearLayout>    <com.bwie.www.shop_nsg1108.sort.view.MyGridView        android:id="@+id/sort_right_grid"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:numColumns="3" /></LinearLayout>

用到的依赖也给大家附上：

// butterknifecompile 'com.jakewharton:butterknife:8.4.0'apt 'com.jakewharton:butterknife-compiler:8.4.0'

// frescocompile 'com.facebook.fresco:fresco:0.12.0'

权限如下：

<!-- 网络 --><uses-permission android:name="android.permission.INTERNET" /><!-- 网络请求 --><uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

分类页面的接口：

// 分类左侧接口public static final String SORT_LEFT = "http://120.27.23.105/";public static final String SORT_LEFT_PATH = "product/getCatagory";// 分类右侧接口public static final String SORT_RIGHT = "http://120.27.23.105/";public static final String SORT_RIGHT_PATH = "product/getProductCatagory";

请求数据我用的retrofit+rxjava结合使用，代码也贴出来分享一下：

ApiService

// 分类 左侧接口@GETObservable<LeftBean> getLeftData(@Url String url);// 分类 右侧接口@POSTObservable<RightBean> getRightData(@Url String url, @QueryMap HashMap<String,String> map);

SortLeftRetrofitFactory

public class SortLeftRetroFactory {    private SortLeftRetroFactory() {    }    private static OkHttpClient httpClient = new OkHttpClient.Builder()            .addInterceptor(new LoggingInterceptor()).connectTimeout(30, TimeUnit.SECONDS)            .readTimeout(30, TimeUnit.SECONDS)            .build();    private static ApiServer retrofitService = new Retrofit.Builder()            .baseUrl(Field.SORT_LEFT)            .addConverterFactory(GsonConverterFactory.create())            .addCallAdapterFactory(RxJavaCallAdapterFactory.create())            .client(httpClient)            .build()            .create(ApiServer.class);    //单列模式    public static ApiServer getInstance() {        return retrofitService;    }}

代码毫无保留的分享给大家啦，End！
