常见疑惑集锦

Info.md

Gradle导入

1.必须导入:

//MVCHelper核心类库
compile 'com.shizhefei:MVCHelper-Library:1.3.2'
//里面有使用recyclerview,所以需要导入recyclerview
compile 'com.android.support:recyclerview-v7:24.0.0'

2.可选:

<1> 使用 https://github.com/LuckyJayce/CoolRefreshView 的刷新控件导入 支持任意View的刷新 ,支持自定义Header,支持NestedScrollingParent,NestedScrollingChild的事件分发,嵌套ViewPager不会有事件冲突

//里面包含一个MVCCoolHelper 是适配这个控件的 MVCHelper
compile 'com.shizhefei:MVCHelper-CoolRefresh:1.3.2'
compile 'com.shizhefei:CoolRefreshView:1.0.1'
compile 'com.android.support:support-v4:24.0.0'

<2> 使用 https://github.com/chrisbanes/Android-PullToRefresh 的刷新控件导入

//里面包含一个MVCPullrefshHelper 是适配这个控件的 MVCHelper
compile 'com.shizhefei:MVCHelper-Pullrefresh:1.3.2'
//由于没有找到gradle排至,我自己把它上传到jcenter上
compile 'com.shizhefei:pulltorefresh:1.0.1'

<3> 使用 https://github.com/liaohuqiu/android-Ultra-Pull-To-Refresh 的刷新控件导入

//里面包含一个MVCUltraHelper 是适配这个控件的 MVCHelper
compile 'com.shizhefei:MVCHelper-UltraRefresh:1.3.2'
//这里6月29号目前最新的,要实时关注新版本去秋大的网站上去看
compile 'in.srain.cube:ultra-ptr:1.0.11'

<4> 使用android v4的SwipeRefreshLayout的作为刷新控件导入

//里面包含一个MVCSwipeRefreshHelper 是适配这个控件的 MVCHelper
compile 'com.shizhefei:MVCHelper-SwipeRefresh:1.3.2'
//v4包应该都有导入吧,v7包里面包含v4包
compile 'com.android.support:support-v4:24.0.0'

<5> 测试用例,可以方便的查看MVCHelper,Task的运行情况和返回数据,还提供了修改接口字段,用于接口测试很方便哦

//MVCHelper的测试用例,继承ABSTestCaseFragment实现List<TestCaseData> getTestCaseDatas()方法
compile 'com.shizhefei:MVCHelper-TestCase:1.3.2'
//里面用到了gson
compile 'com.google.code.gson:gson:2.2.4'

<6> MVCHelper-OkHttp 对OKHttp的简单封装

//MVCHelper的 OKHttp的简单封装
compile 'com.shizhefei:MVCHelper-OkHttp:1.3.2'
//里面用到了okhttp3
compile 'com.squareup.okhttp3:okhttp:3.4.0'
compile 'com.squareup.okio:okio:1.9.0'

<7> MVCHelper-Tasks 一些Task集合,支持类似RxJava的操作符处理多个Task 比如先初始化token,然后再调用获取用户信息task

 IAsyncTask<User> task = Tasks
                    .create(new InitTokenTask())
                    .concatWith(new GetUserTask()));

导入方式

//MVCHelper的 Task操作集合
compile 'com.shizhefei:MVCHelper-Tasks:1.3.2'

一、 MVCHelper

MVCHelper. 实现下拉刷新,滚动底部自动加载更多,分页加载,自动切换显示网络失败布局,暂无数据布局,,真正的MVC架构.

1.Model (IDataSource)数据源,加载数据

同步请求实现IDataSource,异步请求(okhttp,volley,rxjava+retrofit)实现IAsyncDataSource

<1>同步请求(直接返回结果

 //数据源
	
public interface IDataSource<DATA> {
	// 获取刷新的数据
	public DATA refresh() throws Exception;

	// 获取加载更多的数据
	public DATA loadMore() throws Exception;

	// 是否还可以继续加载更多
	public boolean hasMore();
}

例如:分页加载书籍列表数据

public class BooksDataSource implements IDataSource<List<Book>> {
	private int page = 1;
	private int maxPage = 5;

	@Override
	public List<Book> refresh() throws Exception {
		return loadBooks(1);
	}

	@Override
	public List<Book> loadMore() throws Exception {
		return loadBooks(page + 1);
	}

	private List<Book> loadBooks(int page) {
		List<Book> books = new ArrayList<Book>();
		for (int i = 0; i < 20; i++) {
			books.add(new Book("page" + page + "  Java编程思想 " + i, 108.00d));
		}
		this.page = page;
		return books;
	}

	@Override
	public boolean hasMore() {
		return page < maxPage;
	}

}

<2>异步请求(就是请求等待回调函数返回结果

 /**
 * 异步数据源(比如Volley,OkHttp等异步请求使用)
 * @param <DATA>
 */
public interface IAsyncDataSource<DATA> {
    /**
     * 获取刷新的数据
     *
     * @param sender 用于请求结束时发送数据给MVCHelper,MVCHelper再通知IDataAdapter调用notifyDataChenge方法
     * @return 用于提供外部取消请求的处理.比如执行refresh还没请求结束又执行refresh,就会通过上次的RequestHandle取消上次的请求.MVCHelper的destroy也会用这个取消请求
     * @throws Exception
     */
    RequestHandle refresh(ResponseSender<DATA> sender) throws Exception;

    /**
     * 获取加载更多的数据
     *
     * @param sender 用于请求结束时发送数据给MVCHelper,MVCHelper再通知IDataAdapter调用notifyDataChenge方法
     * @return 用于提供外部取消请求的处理.比如执行refresh还没请求结束又执行refresh,就会通过上次的RequestHandle取消上次的请求.MVCHelper的destroy也会用这个取消请求
     * @throws Exception
     */
    RequestHandle loadMore(ResponseSender<DATA> sender) throws Exception;

    /**
     * 是否还可以继续加载更多
     *
     * @return
     */
    boolean hasMore();

}

例如:OkHttp请求

public class BooksOkHttpNormal_DataSource implements IAsyncDataSource<List<Book>> {
    private int mPage;
    private int mMaxPage = 5;

    public BooksOkHttpNormal_DataSource() {
        super();
    }

    @Override
    public RequestHandle refresh(ResponseSender<List<Book>> sender) throws Exception {
        return loadBooks(sender, 1);
    }

    @Override
    public RequestHandle loadMore(ResponseSender<List<Book>> sender) throws Exception {
        return loadBooks(sender, mPage + 1);
    }

    @Override
    public boolean hasMore() {
        return mPage < mMaxPage;
    }

    private RequestHandle loadBooks(final ResponseSender<List<Book>> sender, final int page) throws Exception {
        Request request = new Request.Builder().url("https://www.baidu.com").get().build();
        Call call = OkHttpUtils.client.newCall(request);
        call.enqueue(new Callback() {

            @Override
            public void onFailure(Call call, IOException e) {
                //send 要放在最后一句(请求结束)
                sender.sendError(e);
            }

            @Override
            public void onResponse(Call call, Response response) throws IOException {
                final List<Book> books = new ArrayList<Book>();
                for (int i = 0; i < 15; i++) {
                    books.add(new Book("page" + page + "  Java编程思想 " + i, 108.00d));
                }
                mPage = page;

                //send 要放在最后一句(请求结束)
                sender.sendData(books);
            }
        });
        return new OKHttpRequestHandle(call);
    }
}

public class OKHttpRequestHandle implements RequestHandle {

    private final Call call;

    public OKHttpRequestHandle(Call call) {
        super();
        this.call = call;
    }

    @Override
    public void cancle() {
        call.cancel();
    }

    @Override
    public boolean isRunning() {
        return false;
    }
}

例如:使用 MVCHelper-OkHttp

public class BooksOkHttp_AsyncDataSource implements IAsyncDataSource<List<Book>> {
    private int mPage;
    private int mMaxPage = 5;

    @Override
    public RequestHandle refresh(ResponseSender<List<Book>> sender) throws Exception {
        return loadBooks(sender, 1);
    }

    @Override
    public RequestHandle loadMore(ResponseSender<List<Book>> sender) throws Exception {
        return loadBooks(sender, mPage + 1);
    }

    @Override
    public boolean hasMore() {
        return mPage < mMaxPage;
    }

    private RequestHandle loadBooks(final ResponseSender<List<Book>> sender, final int page) throws Exception {
        GetMethod method = new GetMethod("https://www.baidu.com");
        method.addHeader("a", "aaaaa");
        method.addParam("api_key", "75ee6c644cad38dc8e53d3598c8e6b6c");
        //method 里面已经封装了sender.sendData 和 sendError的方法,只要关心ResponseParser解析Response返回数据就好
        method.executeAsync(sender, new ResponseParser<List<Book>>() {
            @Override
            public List<Book> parse(Response response) throws Exception {
                List<Book> books = new ArrayList<Book>();
                for (int i = 0; i < 15; i++) {
                    books.add(new Book("page" + page + "  Java编程思想 " + i, 108.00d));
                }
                mPage = page;
                return books;
            }
        });
        return method;
    }
}

**详细写法请看 https://github.com/LuckyJayce/MVCHelper/tree/master/app/src/main/java/com/shizhefei/test/models/datasource
里面有

例子:volley

例子:okhttp

例子:rxjava+retrofit

2.View(IDataAdapter) 视图,显示数据

这里不是指Android的view,而是显示数据的概念和显示逻辑

public interface IDataAdapter<DATA> {

	public abstract void notifyDataChanged(DATA data, boolean isRefresh);

	public abstract DATA getData();

	public boolean isEmpty();

}

例如:分页显示书籍列表数据

public class BooksAdapter extends BaseAdapter implements IDataAdapter<List<Book>> {
	private List<Book> books = new ArrayList<Book>();
	private LayoutInflater inflater;

	public BooksAdapter(Context context) {
		super();
		inflater = LayoutInflater.from(context);
	}

	@Override
	public View getView(int position, View convertView, ViewGroup parent) {
		if (convertView == null) {
			convertView = inflater.inflate(R.layout.item_book, parent, false);
		}
		TextView textView = (TextView) convertView;
		textView.setText(books.get(position).getName());
		return convertView;
	}

	@Override
	public void notifyDataChanged(List<Book> data, boolean isRefresh) {
		if (isRefresh) {
			books.clear();
		}
		books.addAll(data);
		notifyDataSetChanged();
	}

	@Override
	public int getCount() {
		return books.size();
	}

	@Override
	public List<Book> getData() {
		return books;
	}


	@Override
	public Object getItem(int position) {
		return null;
	}

	@Override
	public long getItemId(int position) {
		return 0;
	}


}

3.Controller (Activity,Fragment,MVCHelper)控制器

控制器负责调用读取数据,调用显示数据,处理用户交互

Activity负责调度,代码如下

public class MainActivity extends Activity {

	private MVCHelper<List<Book>> mvcHelper;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		// 设置LoadView的factory,用于创建用户自定义的加载失败,加载中,加载更多等布局
		// MVCHelper.setLoadViewFractory(new LoadViewFractory());

		PullToRefreshListView refreshListView = (PullToRefreshListView) findViewById(R.id.pullToRefreshListView);
		mvcHelper = new MVCPullrefshHelper<List<Book>>(refreshListView);

		// 设置数据源
		mvcHelper.setDataSource(new BooksDataSource());
		// 设置适配器
		mvcHelper.setAdapter(new BooksAdapter(this));

		// 加载数据
		mvcHelper.refresh();
	}

	@Override
	protected void onDestroy() {
		super.onDestroy();
		// 释放资源
		mvcHelper.destory();
	}
}

只要写了上述几行代码,恭喜你,你已经实现了分页加载显示书籍列表,实现下拉刷新,滚动底部自动加载更多,在网络请求失败的时候自动显示网络失败,没有数据时显示无数据布局,加载成功时显示书籍列表

4.ILoadViewFractory 自定义 失败布局,无数据布局,加载中布局

实现ILoadViewFractory
MVCHelper.setLoadViewFractory(new LoadViewFractory());
就这样,就会显示你自定义的布局

5.你可以自由的切换刷新类库

1.用CoolRefreshView 作为刷新框架(MVCCoolHelper)
地址:https://github.com/LuckyJayce/CoolRefreshView

	CoolRefreshView coolRefreshView = (CoolRefreshView) findViewById(R.id.coolRefreshView);
	MVCHelper<List<Book>> mvcHelper = new MVCCoolHelper<List<Book>>(coolRefreshView);

	// 设置数据源
	mvcHelper.setDataSource(new BooksDataSource());
	// 设置适配器
	mvcHelper.setAdapter(new BooksAdapter(this));

	// 加载数据
	mvcHelper.refresh();

2.用android-support-v4.jar 的SwipeRefreshLayout作为刷新框架(MVCSwipeRefreshHelper)

	SwipeRefreshLayout swipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.swipeRefreshLayout);
	MVCHelper<List<Book>> mvcHelper = new MVCSwipeRefreshHelper<List<Book>>(swipeRefreshLayout);

	// 设置数据源
	mvcHelper.setDataSource(new BooksDataSource());
	// 设置适配器
	mvcHelper.setAdapter(new BooksAdapter(this));

	// 加载数据
	mvcHelper.refresh();

3.用Android-PullToRefresh-Library作为刷新框架**(MVCPullrefshHelper)**
地址:https://github.com/chrisbanes/Android-PullToRefresh

	PullToRefreshListView refreshListView = (PullToRefreshListView) findViewById(R.id.pullToRefreshListView);
	MVCHelper<List<Book>> mvcHelper = new MVCPullrefshHelper<List<Book>>(refreshListView);

	// 设置数据源
	mvcHelper.setDataSource(new BooksDataSource());
	// 设置适配器
	mvcHelper.setAdapter(new BooksAdapter(this));

	// 加载数据
	mvcHelper.refresh();

4.用android-Ultra-Pull-To-Refresh-library作为刷新框架**(MVCUltraHelper)**
地址:https://github.com/liaohuqiu/android-Ultra-Pull-To-Refresh

	PtrClassicFrameLayout mPtrFrameLayout = (PtrClassicFrameLayout) findViewById(R.id.rotate_header_list_view_frame);

	MVCHelper<List<Book>> mvcHelper = new MVCUltraHelper<List<Book>>(mPtrFrameLayout);
	// 设置数据源
	mvcHelper.setDataSource(new BooksDataSource());
	// 设置适配器
	mvcHelper.setAdapter(new BooksAdapter(this));

	// 加载数据
	mvcHelper.refresh();

5.不使用刷新框架(MVCNormalHelper

	View contentLayout = findViewById(R.id.content_layout);
	MVCHelper<Book> mvcHelper= new MVCNormalHelper<Book>(contentLayout);

	// 设置数据源
	mvcHelper.setDataSource(new BookDetailDataSource());
	// 设置适配器
	mvcHelper.setAdapter(dataAdapter);

	// 加载数据
	mvcHelper.refresh();

6.如果使用其他刷新框架的话可以继承MVCHelper自定义一个

6.任何View的MVC

可以任意的View作为刷新的内容,并且提供相同的MVC架构操作

/***
 * 测试下拉组件的非列表界面
 * 
 * @author LuckyJayce
 *
 */
public class BooDetailActivity extends Activity {

	private MVCHelper<Book> listViewHelper;
	private TextView authorTextView;
	private TextView contentTextView;
	private TextView descriptionTextView;
	private TextView nameTextView;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_bookdetail);

		nameTextView = (TextView) findViewById(R.id.name_textView);
		authorTextView = (TextView) findViewById(R.id.author_textView);
		descriptionTextView = (TextView) findViewById(R.id.description_textView);
		contentTextView = (TextView) findViewById(R.id.content_textView);

		PtrClassicFrameLayout contentLayout = (PtrClassicFrameLayout) findViewById(R.id.rotate_header_list_view_frame);
		listViewHelper = new MVCUltraHelper<Book>(contentLayout);

		// 设置数据源
		listViewHelper.setDataSource(new BookDetailDataSource());
		// 设置适配器
		listViewHelper.setAdapter(dataAdapter);

		// 加载数据
		listViewHelper.refresh();
	}

	@Override
	protected void onDestroy() {
		super.onDestroy();
		// 释放资源
		listViewHelper.destory();
	}

	private IDataAdapter<Book> dataAdapter = new IDataAdapter<Book>() {
		private Book data;

		@Override
		public void notifyDataChanged(Book data, boolean isRefresh) {
			this.data = data;
			authorTextView.setText(data.getAuthor());
			contentTextView.setText(data.getContent());
			descriptionTextView.setText(data.getDescription());
			nameTextView.setText(data.getName());
		}

		@Override
		public boolean isEmpty() {
			return data == null;
		}

		@Override
		public Book getData() {
			return data;
		}
	};

	public void onClickBack(View view) {
		finish();
	}

}

7.不再局限于返回值的个数

原先

public class MovieDetailDataSource implements IDataSource<Movie>{

}

使用Data1的可以传一个泛型返回值
使用Data2的可以传两个泛型返回值
使用Data3的可以传三个泛型参数

public class MovieDetailDataSource implements IDataSource<Data3<Movie, List<Discuss>, List<Movie>>>{

}

二、 TaskHelper

主要用于执行多个任务,通过回调ICallback更新UI

1.Model (ITask, IAsyncTask)

同步请求实现Task,异步请求(okhttp,volley)实现IAsyncTask

/**
 * @param <DATA>
 *            数据类型
 */
public interface Task<DATA> {

	/**
	 * 执行后台任务
	 * 
	 * @param progressSender
	 *            进度更新发送者
	 * @return
	 * @throws Exception
	 */
	public DATA execute(ProgressSender progressSender) throws Exception;

	/**
	 * cancel 和 execute 有可能不在同一个线程,cancle可能在UI线程被调用
	 */
	public void cancel();

}

public interface IAsyncTask<DATA> extends ISuperTask<DATA> {

    /**
     * @param sender 用于请求结束时发送数据给TaskHelper,MVCHelper,然后在通知CallBack的Post回调方法
     * @return 用于提供外部取消请求的处理
     * @throws Exception
     */
    RequestHandle execute(ResponseSender<DATA> sender) throws Exception;

}

例如登陆

public class LoginTask implements Task<User> {
	private String name;
	private String password;

	public LoginTask(String name, String password) {
		super();
		this.name = name;
		this.password = password;
	}

	@Override
	public User execute(ProgressSender progressSender) throws Exception {
		if (name.equals("aaa") && password.equals("111")) {
            return new User("1", "aaa", 23, "中国人");
        } else {
            throw new BizException("用户名或者密码不正确");
        }
	}

	@Override
	public void cancle() {

	}

}

2.View(ICallback)

/**
 *
 * @param <DATA>
 *            数据类型
 */
public interface ICallback<DATA> {

	/**
	 * 执行task之前的回调
	 */
	public void onPreExecute(Object task);

	/**
	 * 进度更新回调
	 * 
	 * @param percent
	 * @param current
	 * @param total
	 * @param exraData
	 */
	public void onProgressUpdate(Object task,int percent, long current, long total, Object exraData);

	/**
	 * 执行task结束的回调,通过code判断是什么情况结束task,(成功,失败,异常,取消)
	 * 
	 * @param code
	 *            返回码
	 * @param exception
	 *            异常信息(throw exception 时才有值)
	 * @param data
	 *            返回的数据
	 */
	public void onPostExecute(Object task,Code code, Exception exception, DATA data);

}

例如登陆请求更新UI

private ICallback<User> loginCallback = new ICallback<User>() {
    @Override
    public void onPreExecute(Object task) {
        loginButton.setEnabled(false);
        loginButton.setText("登陆中...");
    }

    @Override
    public void onProgress(Object task, int percent, long current, long total, Object extraData) {

    }

    @Override
    public void onPostExecute(Object task, Code code, Exception exception, User user) {
        loginButton.setEnabled(true);
        loginButton.setText("登陆");
        switch (code) {
            case EXCEPTION:
                if (exception instanceof BizException) {
                    BizException bizException = (BizException) exception;
                    String fail = bizException.getMessage();
                    Toast.makeText(getApplicationContext(), fail, Toast.LENGTH_SHORT).show();
                    textView.setText(fail);
                } else {
                    Toast.makeText(getApplicationContext(), "网络连接失败", Toast.LENGTH_SHORT).show();
                    textView.setText("网络连接失败");
                }
                break;
            case SUCCESS:
                Toast.makeText(getApplicationContext(), "登陆成功:" + new Gson().toJson(user), Toast.LENGTH_LONG).show();
                textView.setText("登陆成功:" + new Gson().toJson(user));
                break;
            default:
                break;
        }
    }
};

3.Controller (Activity,Fragment,TaskHelper)

Activity负责调度,代码如下

  TaskHelper<Object> taskHelper = new TaskHelper<>();
	
  //注册TaskHelper的callback,所有通过taskHelpe执行的task,都会回调它.
  //taskHelper.registerCallBack(loginCallback);

  TaskHandle taskHandle = taskHelper.execute(new LoginAsyncTask(name, password), loginCallback);
  //TaskHelper 可以执行多个task,TaskHandle对应执行的task,可以执行cancel,对单个task取消
  TaskHandle taskHandle2 = taskHelper.execute(new LoginAsyncTask(name, password), loginCallback);

  //taskHandle.cancel();//执行取消操作

  //taskHelper.destory();//执行释放操作
  //taskHelper.cancelAll();//取消全部

注意:

    1.权限:  
        android.permission.INTERNET  
        android.permission.ACCESS_NETWORK_STATE  
    2.如果不是网络请求数据,比如从数据库获取数据设置 mvcHelper.setNeedCheckNetwork(false);
