前言
看到网上非常火热的retrofit+rxjava的网络框架,自己也动手试着搭建了下,不得不吐槽一波!坑~坑-坑真的是坑!
因为度娘给的都是之前的老版本的集成方法,鄙人按照之前的方法去配置,各种Crash。后来,在大google和自己瞎倒腾下终于是把请求给走通了。下面罗列一下搭建过程(Android studio 搭建)。
retrofit相关配置
使用的版本
-
retrofit
:2.2.0 -
rxandroid
:2.0.1 -
rxjava
:2.0.9
build.gradle文件
compile 'com.squareup.retrofit2:retrofit:2.2.0'
compile 'com.squareup.retrofit2:converter-gson:2.2.0'
compile 'com.squareup.retrofit2:retrofit-adapters:2.2.0'
compile 'com.squareup.retrofit2:adapter-rxjava2:2.2.0'
compile 'io.reactivex.rxjava2:rxandroid:2.0.1'
// Because RxAndroid releases are few and far between, it is recommended you also
// explicitly depend on RxJava's latest version for bug fixes and new features.
compile 'io.reactivex.rxjava2:rxjava:2.0.9'
注意上面第四行的adapter-rxjava2:2.2.0
中一定写上rxjava==2==,老的博客里面都是配置的是的是rxjava这里也是遇到各种坑,不写上2的话会报Unable to create call adapter for io.reactivex.Observable
的异常导致闪退
AndroidManifest.xml配置
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
步入正题,retrofit的初始化以及demo
初始化retrofit
直接上代码
public class ApiService {
//获取单例
public static HttpInterface getApiService() {
return getInstance().mHttpInterface;
}
//在访问HttpMethods时创建单例
private static class SingletonHolder {
private static final ApiService INSTANCE = new ApiService();
}
private static ApiService getInstance(){
return SingletonHolder.INSTANCE;
}
private HttpInterface mHttpInterface;
private ApiService() {
Retrofit retrofit = new Retrofit.Builder().
baseUrl("http://ent.sipmch.com.cn").
addConverterFactory(GsonConverterFactory.create()).
addCallAdapterFactory(RxJava2CallAdapterFactory.create()).
build();
mHttpInterface = retrofit.create(HttpInterface.class);
}
}
定义接口
public interface HttpInterface {
@FormUrlEncoded
@POST("/ModuleDefaultCompany/RentManage/SearchRentNo/")
Observable<RoomResult> search(@Field("CertNo") String idNo);
}
返回结果的JsonBean
public class RoomResult {
public String result;
public String prompWord;
}
方法调用
Apiservice.getService().search(account)
.subscribeOn(Schedulers.newThread())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(roomResult -> {
Utils.showToast(mActivity,roomResult.prompWord);
});
好了大功告成。
其它
最近也是自己在研究App框架的搭建,也是准备做个一个全新的App Demo出来。现在采用的是的MVP+retrofit+rxjava+greenDao+butterKnif
