深圳实时天气数据
关于获取实时天气数据有很多种方法，像聚合数据、和风天气等平台都可以提供数据来源，本文主要使用和风天气SDK获取实时天气数据。以下是使用和风天气SDK来获取地方实时天气数据的步骤。
1.申请获得和风天气的username和key值
访问和风天气官网 和风天气，选择进入"天气API/SDK"：
如无账户，需注册，然后登陆控制台：
接着选择“应用管理”项，点击“新建应用”，填写应用名称：
然后再应用中添加key，输入key的名称和你的应用包名即可申请到一个username和key值：
2.下载Android版和风天气SDK：和风天气SDK
3.启动AndroidStudio，新建工程，将上述步骤下载好的jar包导入到as中:
右击jar包，选中“add as library”，即可导入app下的build.gradle:
同时在此build.gradle下需要添加两项依赖(网络请求和json数据解析用到的类库)：
implementation 'com.squareup.okhttp3:okhttp:3.9.0'
implementation 'com.google.code.gson:gson:2.6.2'
因为要网络来获取实时的天气情况，因此需要在配置文件中添加网络权限：
4.做好以上准备工作之后，以下通过代码实现来获取地方城市的实时天气数据。
xml文件为一个简单的布局：
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:background="#FFF" android:orientation="vertical" tools:context=".MainActivity"> android:id="@+id/tv_city" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textSize="25sp" android:textColor="#000" /> android:id="@+id/tv_tianqi" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textColor="#000" /> android:id="@+id/tv_kongqi" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textColor="#000" /> android:id="@+id/tv_airqlty" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textColor="#000" />
