最后我在 clearRecyclerViewRecyclerBin下， 增加((RecyclerView) rootView).getRecycledViewPool().clear();`解决了
public class RecyclerViewSetter extends ViewGroupSetter {
public RecyclerViewSetter(ViewGroup targetView, int resId) {
super(targetView, resId);
}
public RecyclerViewSetter(ViewGroup targetView) {
super(targetView);
}
@Override
protected void clearRecyclerViewRecyclerBin(View rootView) {
super.clearRecyclerViewRecyclerBin(rootView);
((RecyclerView) rootView).getRecycledViewPool().clear();
}
@Override
public void setValue(Resources.Theme newTheme, int themeId) {
clearRecyclerViewRecyclerBin(mView);
// 遍历子元素与要修改的属性,如果相同那么则修改子View的属性
for (ViewSetter setter : mItemViewSetters) {
for (int i = 0; i < ((RecyclerView) mView).getAdapter().getItemCount(); i++) {
View itemView = ((RecyclerView) mView).getChildAt(i);
if (itemView == null) {
continue;
}
boolean isBaseAdapterHelper = ((RecyclerView) mView).getChildViewHolder(itemView) instanceof BaseAdapterHelper;
if (!isBaseAdapterHelper) {
continue;
}
BaseAdapterHelper baseAdapterHelper = (BaseAdapterHelper) ((RecyclerView) mView).getChildViewHolder(itemView);
setter.mView = baseAdapterHelper.getView(setter.mViewId);
int itemId = setter.getViewId();
if (baseAdapterHelper.getView(itemId) == null) {
continue;
}
setter.setValue(newTheme, themeId);
}
}
}
}
#RxJava
按照以下顺序阅读的话，大概就理解如何使用了
RxJava 使用：给 Android 开发者的 RxJava 详解
图中共有 5 处含有对事件的操作。
由图中可以看出，①和②两处受第一个 subscribeOn() 影响，运行在红色线程；
③和④处受第一个 observeOn() 的影响，运行在绿色线程；
⑤处受第二个 observeOn() 影响，运行在紫色线程；
而第二个 subscribeOn() ，由于在通知过程中线程就被第一个 subscribeOn() 截断，因此对整个流程并没有任何影响。
这里也就回答了前面的问题：当使用了多个 subscribeOn() 的时候，只有第一个 subscribeOn() 起作用。
subscribeOn() 设置影响在它以上的操作，只有第一个 ````subscribeOn`````起效；
observeOn() 设置影响在它以下的操作，直到下一个 observeOn() 设置。
#GreenDAO

* JOIN HTML_ENTITY J1 ON T."HTML_ID"=J1."_id"

*
* @param url
* @return
*/
public List<CollectEntity> queryCollectByhtmlUrl(String url) {
QueryBuilder<CollectEntity> queryBuilder = collectEntityDao.queryBuilder();
queryBuilder.join(CollectEntityDao.Properties.Html_id, HtmlEntity.class, HtmlEntityDao.Properties.Id)

return queryBuilder.list();
}
#Retrofit 使用
##转换器
retrofit RxAndroid+Retrofit环境搭建
转换器可以被添加到支持其他类型。六兄弟模块适应流行的序列化库为您提供方便。 Converters can be added to support other types. Six sibling modules adapt popular serialization libraries for your convenience.
Gson: com.squareup.retrofit2:converter-gson
Jackson: com.squareup.retrofit2:converter-jackson
Moshi: com.squareup.retrofit2:converter-moshi
Protobuf: com.squareup.retrofit2:converter-protobuf
Wire: com.squareup.retrofit2:converter-wire
Simple XML: com.squareup.retrofit2:converter-simplexml
Scalars (primitives, boxed, and String): com.squareup.retrofit2:converter-scalars
直接返回String类型需引入：ScalarsConverterFactory.create()
retrofit = new Retrofit.Builder()
.client(MyOkHttpClient.getMyOkHttpClient().getOkHttpClient())//设置不同的底层网络库
.baseUrl(strBaseUrl)
.addConverterFactory(ScalarsConverterFactory.create())//添加 String类型[ Scalars (primitives, boxed, and String)] 转换器
.addCallAdapterFactory(RxJavaCallAdapterFactory.create())//添加 RxJava 适配器
.build();
返回Gson类型需引入：GsonConverterFactory.create()
retrofit = new Retrofit.Builder()
.client(MyOkHttpClient.getMyOkHttpClient().getOkHttpClient())//设置不同的底层网络库
.baseUrl(strBaseUrl)
.addConverterFactory(GsonConverterFactory.create())//添加 json 转换器
.addCallAdapterFactory(RxJavaCallAdapterFactory.create())//添加 RxJava 适配器
.build();
##Retrofit 结合 RxJava使用
添加依赖
compile 'com.squareup.retrofit2:retrofit:2.0.0-beta4'
compile 'com.squareup.retrofit2:converter-gson:2.0.0-beta4'
compile 'com.squareup.retrofit2:adapter-rxjava:2.0.0-beta4'
compile 'io.reactivex:rxandroid:1.1.0'
compile 'io.reactivex:rxjava:1.1.0'
前两个是 Retrofit 和 Gson 的依赖，第三个是 Retrofit 中 RxJava 转换器的依赖，最后两个就是 RxJava 和 Rx Android 的依赖
编写 API
使用 RxJava 的情况下，接口文件稍有修改，接口中的方法的返回类型不再是 Call 而是 Observable 类型：
public interface GitHub {
@GET("/repos/{owner}/{repo}/contributors")
Call<List<Contributor>> contributors(@Path("owner") String owner,@Path("repo") String repo);
//使用 RxJava 的方法,返回一个 Observable
@GET("/repos/{owner}/{repo}/contributors")
Observable<List<Contributor>> RxContributors(@Path("owner") String owner,@Path("repo") String repo);
}
结合 RxJava 使用的 接口就定义好了，模型类不需要变动，接下来直接进行网络请求
网络请求
使用 RxJava 的 Retrofit 可以直接在 主线程中编写。
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Retrofit retrofit=new Retrofit.Builder()
.baseUrl("https://api.github.com")
.addConverterFactory(GsonConverterFactory.create())//添加 json 转换器
.addCallAdapterFactory(RxJavaCallAdapterFactory.create())//添加 RxJava 适配器
.build();
GitHub gitHub=retrofit.create(GitHub.class);
gitHub.RxContributors("square","retrofit")
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(new Subscriber<List<Contributor>>() {
@Override
public void onCompleted() {
Log.i("TAG","onCompleted");
}
@Override
public void onError(Throwable e) {
}
@Override
public void onNext(List<Contributor> contributors) {
for (Contributor c:contributors){
Log.i("TAG","RxJava-->"+c.getLogin()+" "+c.getId()+" "+c.getContributions());
}
}
});
}
##使用Retrofit和Okhttp实现网络缓存。无网读缓存，有网根据过期时间重新请求
okhttp 请求设置官方文档 使用Retrofit和Okhttp实现网络缓存。无网读缓存，有网根据过期时间重新请求 OuNews 新闻：RetrofitManager类下的 initOkHttpClient 方法 okhttp3.X，retrofit:2.0.0-beta4适用
配置okhttp中的Cache
OkHttpClient okHttpClient;

//设缓存有效期为两天
protected static final long CACHE_STALE_SEC = 60 * 60 * 24 * 2;

#MD实践
##侧滑 NavigationView
最快的方法是创一下新的侧滑模块
代码中：
int[][] states = new int[][] {
new int[] { android.R.attr.state_selected }, // selected
new int[] { android.R.attr.state_focused, android.R.attr.state_pressed }, // pressed
new int[] { }, // default
};
int[] colors = new int[] {
0,
0,
getColor(newTheme)
};
navigationView.setItemTextColor(new ColorStateList(
states,
colors
));
Xml
<android.support.design.widget.NavigationView
android:id="@+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
android:background="?attr/root_view_bg"
app:headerLayout="@layout/nav_header_main"
app:itemTextColor="?attr/text_color"
app:menu="@menu/activity_main_drawer" />
##上下拉：SwipeRefreshLayout
该使用 fitsSystemWindows 了！或该使用 fitsSystemWindows 了！
以哪个为固定:
android:fitsSystemWindows="true"
总结： 为了使得Toolbar有滑动效果，必须做到如下三点：
注：CoordinatorLayout如果是最外的布局要去掉：
1、CoordinatorLayout必须作为整个布局的父布局容器。 2、 给需要滑动的组件设置 app:layout_scrollFlags=”scroll|enterAlways” 属性。 3、给你的可滑动的组件，也就是RecyclerView 或者 NestedScrollView 设置如下属性：
app:layout_behavior="@string/appbar_scrolling_view_behavior"
RecyclerView使用介绍 base-adapter-helper的RecyclerView版
SwipeRefreshLayout.OnRefreshListener 下拉监听
RecyclerView.OnScrollListener 到底监听
recyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
@Override
public void onScrollStateChanged(RecyclerView recyclerView, int newState) {
super.onScrollStateChanged(recyclerView, newState);
if (newState == RecyclerView.SCROLL_STATE_IDLE) {
onListScrolled();
}
}
});
其中 getItemViewType 用来返回当前项是哪种类型布局， getViewTypeCount 返回当前ListView总共多少种类型的布局
如果在 RecyclerView 实现多种Item，只需要实现一个 getItemType 方法，用来返回item的种类
在 onCreateViewHolder 和 onBindViewHolder 方法中，第二个参数就是item的类型
为实现Fragment 不会重新创，仿OuNews的 BaseFragment类中的onCreateView和onDestroyView写法
recyclerView.setOnScrollListener(new RecyclerView.OnScrollListener() { @Override public void onScrolled(RecyclerView recyclerView, int dx, int dy) { super.onScrolled(recyclerView, dx, dy); int lastVisibleItem = ((LinearLayoutManager) mLayoutManager).findLastVisibleItemPosition(); int totalItemCount = mLayoutManager.getItemCount(); //lastVisibleItem >= totalItemCount - 4 表示剩下4个item自动加载，各位自由选择 // dy>0 表示向下滑动 if (lastVisibleItem >= totalItemCount - 4 && dy > 0) { if(isLoadingMore){ Log.d(TAG,"ignore manually update!"); } else{ loadPage();//这里多线程也要手动控制isLoadingMore isLoadingMore = false; } } } });
通过清理项目的缓存可解决。

原因：
在2.0版本的新功能已添加即时运行。
要启用此功能的工具添加了大量的元信息，所以第一个构建和上传需要更多的时间。
请注意有关设置的minSdkVersion 15或更高，以获得任何盈利。
In version 2.0 a new feature was added instant-run.
To enable this feature tool adds a lots of meta information, so the first build and upload takes more time.
Be aware about setting minSdkVersion 15 or higher to get any profit.
解决步骤：
1、点击：Settings → Build, Execution, Deployment → Instant Run
2、取消选择：Enable Instant Run to hot swap code/resoure changes on deploy
这样会取消功能即时运行，但可以解决这个问题。
主要还是BaseQuickAdapter为样本，重写getItemViewType，主要修改如下：
/**
* 返回的布局判断
* @param position
* @return
*/
@Override
public int getItemViewType(int position) {
if (position == 0 || oldCount == position) {
return TYPE_TITLE;
} else {
return TYPE_ITEM;
}
}
/**
* 对不同类型的操作
* @param viewGroup
* @param viewType
* @return
*/
@Override
public BaseAdapterHelper onCreateViewHolder(ViewGroup viewGroup, int viewType) {
View view = null;
switch (viewType) {
case TYPE_TITLE:
view = LayoutInflater.from(viewGroup.getContext()).inflate(titleLayoutResId, viewGroup, false);
break;
case TYPE_ITEM:
view = LayoutInflater.from(viewGroup.getContext()).inflate(itemLayoutResId, viewGroup, false);
break;
}
if (view == null) {
return null;
}
view.setOnClickListener(this);
BaseAdapterHelper vh = new BaseAdapterHelper(view);
return vh;
}
