#### 1、导入依赖 ####

//支付宝支付
        //https://opendocs.alipay.com/open/204/105296
        implementation 'com.alipay.sdk:alipaysdk-android:+@aar'

#### 2、支付工具类 ####

PayUtil.alipay(this, "哪种方式支付');

/**
     * 支付工具类
     */
    public class PayUtil {
        private static final String TAG = "PayUtil";
    
        /**
         * 支付宝支付
         * 支付宝官方开发文档：https://docs.open.alipay.com/204/105295/
         *
         * @param activity
         * @param data
         */
        public static void alipay(Activity activity, String data) {
            //创建运行对象
            Runnable runnable = new Runnable() {
                /**
                 * 子线程执行
                 */
                @Override
                public void run() {
                    //创建支付宝支付任务
                    PayTask alipay = new PayTask(activity);
    
                    //支付结果
                    Map<String, String> result = alipay.payV2(data, true);
    
                    //解析支付结果
                    PayResult resultData = new PayResult(result);
    
                    //发布状态
                    EventBus.getDefault().post(new AlipayStatusChangedEvent(resultData));
                }
            };
    
            //创建一个线程
            Thread thread = new Thread(runnable);
    
            //启动线程
            thread.start();
        }
    }

#### 3、支付宝解析结果 ####

/**
     * 支付宝支付结果解析类
     * 目的是将Map参数解析到对象
     * 可以不用该类
     * 该类来自支付宝支付Demo
     */
    public class PayResult {
        private String resultStatus;
        private String result;
        private String memo;
    
        public PayResult(Map<String, String> rawResult) {
            if (rawResult == null) {
                return;
            }
    
            for (String key : rawResult.keySet()) {
                if (TextUtils.equals(key, "resultStatus")) {
                    resultStatus = rawResult.get(key);
                } else if (TextUtils.equals(key, "result")) {
                    result = rawResult.get(key);
                } else if (TextUtils.equals(key, "memo")) {
                    memo = rawResult.get(key);
                }
            }
        }
    
        @Override
        public String toString() {
            return "resultStatus={" + resultStatus + "};memo={" + memo
                    + "};result={" + result + "}";
        }
    
        /**
         * @return the resultStatus
         */
        public String getResultStatus() {
            return resultStatus;
        }
    
        /**
         * @return the memo
         */
        public String getMemo() {
            return memo;
        }
    
        /**
         * @return the result
         */
        public String getResult() {
            return result;
        }
    
    }

4、支付宝支付状态改变

/**
     * 支付宝支付状态改变了事件
     */
    public class AlipayStatusChangedEvent {
        /**
         * 支付状态
         */
        private PayResult data;
    
        public AlipayStatusChangedEvent(PayResult data) {
            this.data = data;
        }
    
        public PayResult getData() {
            return data;
        }
    
        public void setData(PayResult data) {
            this.data = data;
        }
    }
