Java 安卓工作室：穿越经纬度
我的应用程序是一个天气api，用于收集当前位置的天气信息。我通过输入一个邮政编码来实现这一点，然后异步收集信息。我还使用GooglePlayServices查找通过经度和纬度发送到设备的位置。我想做的是将经度和纬度的值传递到我的API类中，并将其附加到RESTAPI url以查找信息。这很难解释，但我的代码可能会清楚地说明这一点 REST API和GooglePlayServices的代码：Java 安卓工作室：穿越经纬度,java,android,google-maps,android-intent,android-bundle,Java,Android,Google Maps,Android Intent,Android Bundle,我的应用程序是一个天气api，用于收集当前位置的天气信息。我通过输入一个邮政编码来实现这一点，然后异步收集信息。我还使用GooglePlayServices查找通过经度和纬度发送到设备的位置。我想做的是将经度和纬度的值传递到我的API类中，并将其附加到RESTAPI url以查找信息。这很难解释，但我的代码可能会清楚地说明这一点 REST API和GooglePlayServices的代码： import android.app.Activity; import android.content.
