一 .前置工作
1.首先，前置工作肯定要先搭建支付宝沙盒环境。打开支付宝的开发者平台，地址：支付宝开放平台，先登录账号，如下图
2.接下来就点击旁边的“控制台”，进入控制台页面，然后鼠标滚轮滑倒最下面，下图所示
点击“开发工具推荐”中的沙箱，进入沙箱调试页面，下图所示
接下来
然后就要下载生成密钥的工具，安装软件就不用兄弟教学了吧，你可以的
3.然后打开“支付宝开放平台密钥工具”，点击生成密钥
最后生成页面
回到支付宝开放平台页面操作，复制公钥进去点击保存
4.然后下载支付宝沙盒版本去到要操作的设备中去，然后登录
最后打开沙箱版支付宝，登录买家账号，注意：一定要登录买家账号
5.到这一步，前置工作已经全部完成，已经离成功不远了
二.代码层面
1.创建一个新的项目（这个就不用教了）
我这里就只做一个简单得页面算了，上代码！
创建项目之后在app模块中的build.gradle中加入支付的依赖
implementation 'com.alipay.sdk:alipaysdk-android:+@aar'
2.布局页面 activity_main.xml
xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/main" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".MainActivity"> android:layout_width="match_parent" android:layout_height="match_parent" android:id="@+id/rc_view"/>
3.接下来左一个列表视图需要的适配器 RcAdapter
public class RcAdapter extends RecyclerView.Adapter
private List
public SetItemOnClickListener listener;
public RcAdapter( List
this.list = list;
}
@Override
public RcViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
return new RcViewHolder(LayoutInflater.from(parent.getContext()).inflate(R.layout.item_rc, parent, false));
}
@Override
public void onBindViewHolder(RcViewHolder holder, int position) {
holder.tv_name.setText(list.get(position).getName());
holder.tv_money.setText(String.valueOf(list.get(position).getMoney()));
holder.itemView.setOnClickListener(v -> {
listener.setItemOnClickListener(position);
});
}
@Override
public int getItemCount() {
return list.size();
}
class RcViewHolder extends RecyclerView.ViewHolder {
TextView tv_name, tv_money;
public RcViewHolder(View v) {
super(v);
tv_name = v.findViewById(R.id.tv_name);
tv_money = v.findViewById(R.id.tv_money);
}
}
public void setOnClickListener(SetItemOnClickListener listener) {
this.listener = listener;
}
public interface SetItemOnClickListener {
void setItemOnClickListener(int position);
}
}
4.对应的数据类 RcBean
public class RcBean {
private String name;
private BigDecimal money;
public RcBean(String name, BigDecimal money) {
this.name = name;
this.money = money;
}
public RcBean() {
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public BigDecimal getMoney() {
return money;
}
public void setMoney(BigDecimal money) {
this.money = money;
}
}
5.列表 item对应的布局
android:layout_width="match_parent" android:layout_height="wrap_content" xmlns:app="http://schemas.android.com/apk/res-auto"> android:id="@+id/l1" android:layout_width="match_parent" android:layout_height="wrap_content" android:padding="10dp" android:orientation="vertical" app:layout_constraintTop_toTopOf="parent"> android:id="@+id/tv_name" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="name"/> android:id="@+id/tv_money" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="money"/> android:layout_width="match_parent" android:layout_height="1dp" app:layout_constraintTop_toBottomOf="@id/l1" android:layout_marginTop="5dp" android:background="@color/black"/>
6.然后复制官方给的demo中的三个类
第一个 OrderInfoUtil2_0
public class OrderInfoUtil2_0 {
/**
* 构造授权参数列表
*
* @param pid
* @param app_id
* @param target_id
* @return
*/
public static Map
SnowflakeIdGenerator snowflakeIdGenerator = new SnowflakeIdGenerator(1);
Map

keyValues.put("sign_type", rsa2 ? "RSA2" : "RSA");
return keyValues;
}
/**

*/
public static Map
Map
keyValues.put("app_id", app_id);
keyValues.put("biz_content", "{\"timeout_express\":\"30m\",\"product_code\":\"QUICK_MSECURITY_PAY\",\"total_amount\":\"" + total_amount + "\",\"subject\":\"1\",\"body\":\"我是测试数据\",\"out_trade_no\":\"" + getOutTradeNo() + "\"}");

keyValues.put("version", "1.0");
return keyValues;
}
/**

*
* @param map
* 支付订单参数

*/
public static String buildOrderParam(Map
List
StringBuilder sb = new StringBuilder();
for (int i = 0; i < keys.size() - 1; i++) {
String key = keys.get(i);
String value = map.get(key);

sb.append("&");
}
String tailKey = keys.get(keys.size() - 1);
String tailValue = map.get(tailKey);
sb.append(buildKeyValue(tailKey, tailValue, true));
return sb.toString();
}
/**

*/
private static String buildKeyValue(String key, String value, boolean isEncode) {
StringBuilder sb = new StringBuilder();
sb.append(key);
sb.append("=");
if (isEncode) {
try {
sb.append(URLEncoder.encode(value, "UTF-8"));
} catch (UnsupportedEncodingException e) {
sb.append(value);
}
} else {
sb.append(value);
}
return sb.toString();
}
/**
* 对支付参数信息进行签名
*
* @param map
* 待签名授权信息
*
* @return
*/
public static String getSign(Map
List
// key排序
Collections.sort(keys);
StringBuilder authInfo = new StringBuilder();
for (int i = 0; i < keys.size() - 1; i++) {
String key = keys.get(i);
String value = map.get(key);
authInfo.append(buildKeyValue(key, value, false));
authInfo.append("&");
}
String tailKey = keys.get(keys.size() - 1);
String tailValue = map.get(tailKey);
authInfo.append(buildKeyValue(tailKey, tailValue, false));
String oriSign = SignUtils.sign(authInfo.toString(), rsaKey, rsa2);
String encodedSign = "";
try {
encodedSign = URLEncoder.encode(oriSign, "UTF-8");
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
return "sign=" + encodedSign;
}
/**
* 要求外部订单号必须唯一。
* @return
*/
private static String getOutTradeNo() {
SimpleDateFormat format = new SimpleDateFormat("MMddHHmmss", Locale.getDefault());
Date date = new Date();
String key = format.format(date);
Random r = new Random();
key = key + r.nextInt();
key = key.substring(0, 15);
return key;
}
}
第二个 SignUtils
public class SignUtils {
private static final String ALGORITHM = "RSA";
private static final String SIGN_ALGORITHMS = "SHA1WithRSA";
private static final String SIGN_SHA256RSA_ALGORITHMS = "SHA256WithRSA";
private static final String DEFAULT_CHARSET = "UTF-8";
private static String getAlgorithms(boolean rsa2) {
return rsa2 ? SIGN_SHA256RSA_ALGORITHMS : SIGN_ALGORITHMS;
}
public static String sign(String content, String privateKey, boolean rsa2) {
try {
PKCS8EncodedKeySpec priPKCS8 = new PKCS8EncodedKeySpec(
Base64.decode(privateKey,Base64.DEFAULT));
KeyFactory keyf = KeyFactory.getInstance(ALGORITHM);
PrivateKey priKey = keyf.generatePrivate(priPKCS8);
java.security.Signature signature = java.security.Signature
.getInstance(getAlgorithms(rsa2));
signature.initSign(priKey);
signature.update(content.getBytes(DEFAULT_CHARSET));
byte[] signed = signature.sign();
return Base64.encodeToString(signed, Base64.DEFAULT);
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
}
第三个SnowflakeIdGenerator
public class SnowflakeIdGenerator {
private static final long START_EPOCH = 1609459200000L; // 2021-01-01 00:00:00
private static final long MACHINE_ID_BITS = 5L;
private static final long SEQUENCE_BITS = 15L;
private static final long MAX_MACHINE_ID = ~(-1L << MACHINE_ID_BITS);
private static final long MAX_SEQUENCE = ~(-1L << SEQUENCE_BITS);
private long machineId;
private long sequence = 0L;
private long lastTimestamp = -1L;
public SnowflakeIdGenerator(long machineId) {
if (machineId > MAX_MACHINE_ID || machineId < 0) {
throw new IllegalArgumentException("Machine ID can't be greater than " + MAX_MACHINE_ID + " or less than 0");
}
this.machineId = machineId;
}
public synchronized String nextId() {
long timestamp = System.currentTimeMillis();
// 检查时间戳是否回退
if (timestamp < lastTimestamp) {
throw new RuntimeException("Clock moved backwards. Refusing to generate ID");
}
if (lastTimestamp == timestamp) {
// 如果在同一毫秒内，增加序列号
sequence = (sequence + 1) & MAX_SEQUENCE;
if (sequence == 0) {
// 序列号达到最大值，需要等待下一毫秒
timestamp = waitNextMillis(lastTimestamp);
}
} else {
// 不同毫秒，重置序列号
sequence = 0L;
}
lastTimestamp = timestamp;
long uniqueId = ((timestamp - START_EPOCH) << (MACHINE_ID_BITS + SEQUENCE_BITS)) | (machineId << SEQUENCE_BITS) | sequence;
Log.d("uniqueId = ", String.valueOf(uniqueId));
String idStr = String.valueOf(uniqueId).substring(0, 18);
return idStr;
}
private long waitNextMillis(long lastTimestamp) {
long timestamp;
try {
while ((timestamp = System.currentTimeMillis()) <= lastTimestamp) {
Thread.sleep(1);
}
} catch (InterruptedException e) {
throw new RuntimeException("Interrupted while waiting for next millisecond", e);
}
return timestamp;
}
private String toBase36(long id) {
return Long.toString(id, 36);
}
}
最后给出MainActivity.java
public class MainActivity extends AppCompatActivity {
public static final String APPID = "9021000141649348";
//私钥
public static final String RSA2_PRIVATE = "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";
