我正在创建一个简单的库来调用天气api,在我的lib项目中,我使用RxJava和RxAndroid并进行了HTTP调用的改进。
我的WeatherService进行呼叫并以json形式接收结果,并且需要进行一些操作并将其作为Single<CurrentWeather>
返回给客户端应用。
在我的lib项目中,我添加了rx和改造所需的所有依赖项。
我的图书馆成绩单:
ext{
rxJava = "2.1.17"
rxAndroid = "2.0.2"
support = "27.1.1"
retrofitVersion = "2.4.0"
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation "com.android.support:appcompat-v7:$support"
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
implementation "com.squareup.retrofit2:retrofit:$retrofitVersion"
implementation "com.squareup.retrofit2:converter-gson:$retrofitVersion"
implementation "com.squareup.retrofit2:adapter-rxjava2:$retrofitVersion"
implementation "io.reactivex.rxjava2:rxandroid:$rxAndroid"
implementation "io.reactivex.rxjava2:rxjava:$rxJava"
}
现在在MainActivity的示例应用程序中,我想测试一个函数以查看它是否按预期工作,但是当我尝试调用返回Single的函数时,它显示易出错错误:
error: cannot access Single
class file for io.reactivex.Single not found
lib函数声明:
public Single<Current> getCurrentWeather(double lat, double lng) {
return mClient.getWeather(lat + "," + lng).flatMap(new Function<JSONObject, SingleSource<Current>>() {
@Override
public SingleSource<Current> apply(JSONObject jsonObject) throws Exception {
//parse jsonObject and return as Single<Current>
return Single.create(new SingleOnSubscribe<Current>() {
@Override
public void subscribe(SingleEmitter<Current> emitter) throws Exception {
Current current = new Current();
emitter.onSuccess(current);
}
});
}
});
}
客户端应用程序MainActivity:这是编译错误。
WeatherService.getIsnstance().getCurrentWeather(32.5554, 35.545)
客户端应用gradle:
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
implementation project(":weatherlib")
}
客户端应用设置。gradle:
include ':app', ':weatherlib'
我在这里想念什么吗?
这是否意味着每个希望使用此lib的人都必须在gradle中添加rx依赖项?
