GitHub上Daily项目的个人分析

对github上别人项目的分析。觉得他框架搭的不错。好好向他学习学习。
https://github.com/spring2613/Daily
项目亮点颇多，自己找了自己觉得不错的点，分析分析。

下面就开始分析一下吧：

Application–>

我分析代码通常从Application开始分析起来，那么就先看看别人的Application怎么做的吧。
清单文件中：

    <application
        android:name=".App"
        android:allowBackup="true"
        android:fullBackupContent="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:largeHeap="true"
        android:theme="@style/BaseAppTheme">
    </application>

Android application 和 activity 标签详解：http://blog.youkuaiyun.com/self_study/article/details/54020909

Application中，也是App
也就是各种初始化。

setupDatabase

SplashActivity–>

清单文件中：

        <activity
            android:name=".mvp.ui.activities.SplashActivity"
            android:configChanges="orientation|keyboardHidden|screenSize"
            android:theme="@style/AppTheme.FullScreen">
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>

                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>

最先启动的Activity配置
关于Intent详解：http://blog.youkuaiyun.com/u012637501/article/details/41080891

SplashActivity–>

再来看看这个SplashActivity：

Property Animation

ButterKnife

RxAndroid RxJava

BaseActivity–>

抽象、泛型 ：

public abstract class BaseActivity<T extends BasePresenter> extends AppCompatActivity {
    protected T mPresenter;

    public abstract int getLayoutId();

    public abstract void initInjector();

    public abstract void initViews();
 }

ActivityComponent

DrawerLayout

Toolbar

onNewIntent：

    @Override
    protected void onNewIntent(Intent intent) {
        super.onNewIntent(intent);
        setIntent(intent);
    }

RefWatcher

NewsActivity–>

DrawerLayout

NavigationView

CoordinatorLayout

AppBarLayout

Toolbar

TabLayout

ViewPager

FloatingActionButton

Snackbar

MVP

Rx

butterknife

dagger

这么多东西结合一起玩。感觉对于现在主流来说是必须会玩的。

BaseFragment–>

跟Activity差不多也是通过泛型跟Presenter关联

NewsListFragment

RecyclerView

SwipeRefreshLayout

Rx

butterknife

dagger

MVP

BaseRecyclerViewAdapter–>

泛型

常用的增删改查

Footer加载更多

setItemAppearAnimation

    protected void setItemAppearAnimation(RecyclerView.ViewHolder holder, int position, @AnimRes int type) {
        if (position > mLastPosition/* && !isFooterPosition(position)*/) {
            Animation animation = AnimationUtils.loadAnimation(holder.itemView.getContext(), type);
            holder.itemView.startAnimation(animation);
            mLastPosition = position;
        }
    }

NewsListAdapter–>

onCreateViewHolder

精彩用法：

    @Override
    public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, final int viewType) {
        View view;
        switch (viewType) {
            case TYPE_FOOTER:
                view = getView(parent, R.layout.item_news_footer);
                return new FooterViewHolder(view);
            case TYPE_ITEM:
                view = getView(parent, R.layout.item_news);
                final ItemViewHolder itemViewHolder = new ItemViewHolder(view);
                setItemOnClickEvent(itemViewHolder, false);
                return itemViewHolder;
            case TYPE_PHOTO_ITEM:
                view = getView(parent, R.layout.item_news_photo);
                final PhotoViewHolder photoItemViewHolder = new PhotoViewHolder(view);
                setItemOnClickEvent(photoItemViewHolder, true);
                return photoItemViewHolder;
            default:
                throw new RuntimeException("there is no type that matches the type " +
                        viewType + " + make sure your using types correctly");
        }
    }

Glide

Google推荐的图片加载库Glide

多种灵活使用ViewHolder

butterknife

MVP中NewsActivity–>

NewsActivity–>NewsView–>NewsPresenterImpl–>NewsPresenter–>NewsInteractorImpl–>NewsInteractor–>NewsChannelTable–>NewsChannelTableManager

NewsInteractor中用到了Rx的Subscription

public interface NewsInteractor<T> {

    Subscription lodeNewsChannels(RequestCallBack<T> callBack);
}

NewsInteractorImpl中用到了Rx的Observable

用到了dagger的@Inject

public class NewsInteractorImpl implements NewsInteractor<List<NewsChannelTable>> {

    @Inject
    public NewsInteractorImpl() {

    }

    @Override
    public Subscription lodeNewsChannels(final RequestCallBack<List<NewsChannelTable>> callBack) {
        return Observable
                .create(new Observable.OnSubscribe<List<NewsChannelTable>>() {
                    @Override
                    public void call(Subscriber<? super List<NewsChannelTable>> subscriber) {
                        NewsChannelTableManager.initDB();
                        subscriber.onNext(NewsChannelTableManager.loadNewsChannelsMine());
                        subscriber.onCompleted();
                    }
                })
                .compose(TransformUtils.<List<NewsChannelTable>>defaultSchedulers())
                .subscribe(new Subscriber<List<NewsChannelTable>>() {
                               @Override
                               public void onCompleted() {

                               }

                               @Override
                               public void onError(Throwable e) {
                                   callBack.onError(App.getAppContext().getString(R.string.db_error));
                               }

                               @Override
                               public void onNext(List<NewsChannelTable> newsChannelTables) {
                                   callBack.success(newsChannelTables);
                               }
                           }
                );
    }
}

NewsChannelTable中用到了greendao

NewsChannelTableManager中

repository（仓库）中分为（db）和（network）
NewsChannelTableManager属于从db repository中获取数据

MVP中NewsListFragment–>

NewsListFragment–>NewsListView–>NewsListPresenterImpl–>NewsListPresenter–>NewsListInteractorImpl–>NewsListInteractor–>NewsSummary–>RetrofitManager–>NetUtil

NewsListInteractor中用到了Rx的Observable

public interface NewsListInteractor<T> {
    Subscription loadNews(RequestCallBack<T> listener, String type, String id, int startPage);
}

NewsListInteractorImpl(暂时没看懂。)

public class NewsListInteractorImpl implements NewsListInteractor<List<NewsSummary>> {

    //    private boolean mIsNetError;
    @Inject
    public NewsListInteractorImpl() {
    }

    @Override
    public Subscription loadNews(final RequestCallBack<List<NewsSummary>> listener, String type,
                                 final String id, int startPage) {
//        mIsNetError = false;
        // 对API调用了observeOn(MainThread)之后，线程会跑在主线程上，包括onComplete也是，
        // unsubscribe也在主线程，然后如果这时候调用call.cancel会导致NetworkOnMainThreadException
        // 加一句unsubscribeOn(io)
        return RetrofitManager.getInstance(HostType.NETEASE_NEWS_VIDEO).getNewsListObservable(type, id, startPage)
                .flatMap(new Func1<Map<String, List<NewsSummary>>, Observable<NewsSummary>>() {
                    @Override
                    public Observable<NewsSummary> call(Map<String, List<NewsSummary>> map) {
                        if (id.endsWith(ApiConstants.HOUSE_ID)) {
                            // 房产实际上针对地区的它的id与返回key不同
                            return Observable.from(map.get("北京"));
                        }
                        return Observable.from(map.get(id));
                    }
                })
                .map(new Func1<NewsSummary, NewsSummary>() {
                    @Override
                    public NewsSummary call(NewsSummary newsSummary) {
                        String ptime = MyUtils.formatDate(newsSummary.getPtime());
                        newsSummary.setPtime(ptime);
                        return newsSummary;
                    }
                })
//                .toList()
                .distinct()
                .toSortedList(new Func2<NewsSummary, NewsSummary, Integer>() {
                    @Override
                    public Integer call(NewsSummary newsSummary, NewsSummary newsSummary2) {
                        return newsSummary2.getPtime().compareTo(newsSummary.getPtime());
                    }
                })
                .compose(TransformUtils.<List<NewsSummary>>defaultSchedulers())
                .subscribe(new Subscriber<List<NewsSummary>>() {
                    @Override
                    public void onCompleted() {
                        KLog.d();
//                        checkNetState(listener);
                    }

                    @Override
                    public void onError(Throwable e) {
                        KLog.e(e.toString());
//                        checkNetState(listener);
//                        if (!NetUtil.isNetworkAvailable(App.getAppContext())) {
                        listener.onError(MyUtils.analyzeNetworkError(e));
//                        }
                    }

                    @Override
                    public void onNext(List<NewsSummary> newsSummaries) {
                        KLog.d();
                        listener.success(newsSummaries);
                    }
                });

    }

//    private void checkNetState(RequestCallBack<List<NewsSummary>> listener) {
//        if (!NetUtil.isNetworkAvailable(App.getAppContext())) {
//            mIsNetError = true;

Daily这算是别人做的框架模板，里面有很多知识点。
对于我来说挺陌生的，还得下功夫一个一个学好。
MVP + Rx ＋Retrofit＋OkHttp3 +Dagger入门的一个很好的demo
如果+上模块化，组件化，那些玩意就更厉害了。
