小编Cha*_*aka的帖子

我是React-native的新手.我尝试使用我的应用程序添加谷歌地图 npm i react-native-maps --save

我参考这个https://github.com/react-community/react-native-maps/blob/master/docs/installation.md并按照所有步骤操作.我获得了Google API并将其放入AndroidManifest.我的Google Play服务版本为14.5.74.我也加了android/app/build.gradle.这里是

分机{
buildToolsVersion = "27.0.3"
的minSdkVersion = 16
compileSdkVersion = 27
targetSdkVersion = 26
supportLibVersion = "27.1.1"
googlePlayServicesVersion = "74年5月14日"
androidMapsUtilsVersion = "0.5+"}

我曾经

"dependencies":{
"@ babel/runtime":"^ 7.1.5",
"react":"16.5.0",
"react-native":"0.57.0",
"react-native-maps":" ^ 0.22.1"},

但是我收到了一个错误

Postman formdata 工作正常，但这会在 http 500 错误后返回。这个块有什么问题。

我调用 API Called 并像这样获取数组。

0:
2019-07-25: {title: "Sub task for 11"}
__proto__: Object
1: {2019-07-19: {…}}
2: {2019-07-24: {…}}
3: {2019-07-26: {…}}
4: {2019-07-25: {…}}
5: {2019-07-24: {…}}
6: {2019-07-25: {…}}
7: {2019-07-25: {…}}

我想将上面的对象数组转换为对象。像下面..

     "2019-07-25": {title: "Sub task for 11"},
     "2019-07-19": {title: "Sub task for 12"},
     "2019-07-24": {title: "Sub task for 13"},
     "2019-07-26": {title: "Sub task for 14"}

我试过了，但我不能像这样转换。请任何人知道如何转换这个帮助我。谢谢
