HttpResponse cannot be resolved to a type android

解决方法：

确定导入了httpclient包
将android6.0 改成5.0

.w.s.m.s.DefaultHandlerExceptionResolver : Resolved [org.springframework.web.HttpMediaTypeNotAcce...

当想要返回的是json数据，produces写的"text/plain",会报错

@RequestMapping(value = "/getDynamicByDynamicId1",produces = "text/plain")
@ResponseBody
public Dynamic getDynamicByDynamicId1(){
    System.out.println();
    return dynamicMapper.getDynamicByAnnotationFromDynamicId(1l);
}

Whitelabel Error Page

This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Acceptable, status=406).

Could not find acceptable representation

org.springframework.web.HttpMediaTypeNotAcceptableException: Could not find acceptable representation

改为

@RequestMapping(value = "/getDynamicByDynamicId1",produces = "application/json")
@ResponseBody
public Dynamic getDynamicByDynamicId1(){
    System.out.println();
    return dynamicMapper.getDynamicByAnnotationFromDynamicId(1l);
}

android-import android.support cannot be resolved

解决方法：

1、右击当前工程，查找Properties

2、选择Java Build Path

3、选择Libraries tab，点击右边面板的Add External JARs按钮

4、选择android-support-v4.jar文件（你安装的Android SDK 目录），这一文件的常见路径为:D:\android-sdks\extras\android\support\v4\android-support-v4.jar

(有可能是缺少别的,同理)

5、完成添加后，选择Order and Export标签，勾选，确认即可。

android.support.v4.view.NestedScrollingChild cannot be resolved

OSC 请你来轰趴啦！1028 苏州源创会，一起寻宝 AI 时代

问题记录：

我用 eclipse 引入了 Sdk 自带的 android-support-v7-recyclerview.jar，然后使用 SwiperefreshLayout+RecyclerView 做下拉刷新，在写适配器的时候出现了一个问题；

这里写图片描述
最后发现是我 android-support-v4.jar 和 android-support-v7-recyclerview.jar 不一致导致的，最后换了 v4 jar 包就解决的，不然有些方法不能使用的，做个小记录。

小结：

在引入官方 support 库时，务必保证版本一致；在引入第三方库时，务必查看第三方库的依赖库，避免坑。！
