之前都是使用和风API获取天气数据,也可以,但SDK会了以后,更加简单直接。而且功能也比API更强大,代码更简洁。下面是我折腾差不多一周的成果,这些会了之后,获取天气预报,显示城市,天气图标什么的也都能简单的完成。今天先把这个发出去,过两天把其他 的做完了再发。

因为和风的天气代码和json格式不断的变,所以以下代码适用于4.8版SDK,其他版本我找到了不少,基本都不适用。因为我对JAVA几乎不懂,经过自己不断实验、摸索,最后成功。所以代码肯定不好看,很多也是抄别人的,但不是抄一个人的,所以这里表示感谢,但无法一一列举。

以下是全部详细步骤及全部代码,按照我写的来一定能成功。

一、注册和风用户:https://id.qweather.com/#/login

后面验证过程就不讲了。登录后到最下面,“开发者控制台”。

android studio 用和风天气api 和风天气图标怎么下载_app_02

点击进入。看到下面界面。

二、创建应用获取publicID 和key(关键):

点击上图上的:马上创建一个上面的“+”号。打开下图。

android studio 用和风天气api 和风天气图标怎么下载_和风天气SDK_04

 点击左右“免费开发版”后,下图:

android studio 用和风天气api 和风天气图标怎么下载_app_05

 这个可以随便写。下一步下图:

点击Andriod SDK。下一步,下图:

android studio 用和风天气api 和风天气图标怎么下载_android_07

 都是必填项:上面的名称可以随便写。下面的“绑定packageName”内的东西必须与你开发的app的名称一样,据说不一样获取不到数据,我没试过。一般是这种格式:com.example.thirdversionclock 就在andriodmanifest.mxl里面,下图的位置,这个名字在申请的时候可以随便取,后面想改啥改啥,随便改。

 下一步就完成了。下面就是我们要的关键的东西:publicID 和key.

 三、(andriod stutio3.5)新建一个app,名字最好就上面填的,不要在在上图的编辑里面修改app名字。

第一步选择app基本外观,我选择的是全屏的。

 下一步,下图。上面的名称看第二行,写后面的就行了。下面第二个红框是语言,选java. 点finish,完成新建项目。

 四、重点:代码部分。

具体参照开发文档。https://dev.qweather.com/docs/android-sdk/

对于小白有点小坑,我把详细步骤写一下。

1、下载SDK文件:Android SDK配置 | 和风天气开发服务

2、添加SDK文件。把上面的文件拷贝到刚才建的那个项目文件夹下

android studio 用和风天气api 和风天气图标怎么下载_和风天气SDK_12

上面位置1为项目视图,位置2显示的是项目保存的路径,默认是在C盘。在项目路径下面找到/app/libs文件夹,把下载的SDK文件拷贝进去。我这个路径是:E:\AndroidStudioProjects\Weather\app\libs,然后在andriod studio里面,上面视图,找到这个文件,并在这个文件上点击右建,弹出菜单如下,点击下面红框内,导入库。

 没导入前面没三角标:

导入后前面有三角标:

android studio 用和风天气api 和风天气图标怎么下载_java_15

 3、配置Android Manifest 添加权限。文件位置下图:

android studio 用和风天气api 和风天气图标怎么下载_java_16

 上面框是andriod视图,app下面的manifests下面就是那个文件,双击打开。添加下面代码:


<uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> <uses-permission android:name="android.permission.READ_PHONE_STATE" /> <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />


意义:

允许连接网络

android.permission.INTERNET

访问GPS定位

android.permission.ACCESS_FINE_LOCATION

访问设备状态

android.permission.READ_PHONE_STATE

访问WIFI状态

android.permission.ACCESS_WIFI_STATE

添加位置:

android studio 用和风天气api 和风天气图标怎么下载_android_17

 4、引用库。内容:


implementation 'com.squareup.okhttp3:okhttp:3.12.12' implementation 'com.google.code.gson:gson:2.6.2'


位置见下图:andriod视图,下面的build.gradle(module.app),双击打开。

android studio 用和风天气api 和风天气图标怎么下载_app_18

 上面的代码和开发文档里面的不一样,按我的写。

其他混淆什么的我就没做了。

下面是主要代码部分:

五、重要:主要文件代码:

1、布局文件全代码:这里没什么好讲的。复制覆盖粘贴就行了。(项目名要相同,不然不行)

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_marginTop="110dp"
    android:textColor="#000"/>

    <TextView
        android:id="@+id/tv_fengxiang"
        android:layout_width="wrap_content"

        android:textSize="30dp"
        android:layout_marginTop="150dp"
        android:textColor="#000"
        />

    <!-- This FrameLayout insets its children based on system windows using
         android:fitsSystemWindows. -->
    <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fitsSystemWindows="true">

        <LinearLayout
            android:id="@+id/fullscreen_content_controls"
            style="?metaButtonBarStyle"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="bottom|center_horizontal"
            android:background="@color/black_overlay"
            android:orientation="horizontal"
            tools:ignore="UselessParent">

            <Button
                android:id="@+id/dummy_button"
                style="?metaButtonBarButtonStyle"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:text="@string/dummy_button" />

        </LinearLayout>
    </FrameLayout>

</FrameLayout>

2、java文件关键代码:

public void queryWeather(){
        QWeather.getWeatherNow(FullscreenActivity.this, "CN101280603", Lang.ZH_HANS, Unit.METRIC, new QWeather.OnResultWeatherNowListener(){
            public static final String TAG="he_feng_now";
            @Override
            public void onError(Throwable e) {
                Log.i(TAG, "onError: ", e);
                System.out.println("Weather Now Error:"+new Gson());
            }
    @Override


            public void onSuccess(WeatherNowBean weatherBean) {
                //Log.i(TAG, "getWeather onSuccess: " + new Gson().toJson(weatherBean));
                System.out.println("获取天气成功: " + new Gson().toJson(weatherBean));
                //先判断返回的status是否正确,当status正确时获取数据,若status不正确,可查看status对应的Code值找到原因
                if (Code.OK == weatherBean.getCode()) {
                    WeatherNowBean.NowBaseBean now = weatherBean.getNow();
                    String tianqi=now.getText();
                    String wendu=now.getTemp()+"℃";
                    String fengli=now.getWindScale();
                    String fengxiang=now.getWindDir();
                    tv_tianqi.setText("当前天气:"+tianqi);
                    tv_wendu.setText("当前温度:"+wendu);
                    tv_fengxiang.setText("风向:"+fengxiang);
                    tv_fengli.setText("风力:"+fengli+"级");

                } else {
                    //在此查看返回数据失败的原因
                    Code code = weatherBean.getCode();
                    System.out.println("失败代码: " + code);
                    //Log.i(TAG, "failed code: " + code);
                }
            }

        });
    };

 全部代码:因为是全屏的界面很多代码不是必须的。如果文件名相同也可以直接复制覆盖粘贴。

 HeConfig.init("你的publicID", "你的key");这一行引号里的内容要修改成你的。
