GitHub三方支付宝Deom
先上效果图

拉起支付界面

支付完成

开发前准备

首先进入蚂蚁金服开放平台,使用手机端支付宝App扫描二维码进入主页.
第一步
找到开发中心进入创建应用 ---> 网页应用 ---> 确认创建 ---> 选择开发中你所需要的功能并且同意协议

选择功能

第二步找到开放设置

设置应用公钥
设置公钥
支付宝密钥生成器
下载zip包解压到[ 无中文目录 (图一) ]
打开解压出来的 (rsa_public_key.pem) [ 图二 ]
将公钥复制粘贴到设置公钥里点击验证公钥正确性 [ 图三 ]
解压后点击配置私钥的bat(这时候需要我们刚才配置RSA里面的私有密钥) [ 图四 rsa_private_key_pkcs8.pem ]
将这串私钥粘贴后生成签名复制出来验证 [ 图五图六 ]
验证成功后点击保存
点击查找支付宝公钥保存到本地 [ 图七 ]

第三步
同意协议之后提交审核嘟嘟嘟就完成啦

继承三方支付

我们先看一下支付流程图 [ 图九 ]

图九

目将volley.jar导入进libs目录下并且引入Studio[ 图十图十一 ]

图十

图十一

将三方支付宝所下载的arr导入libs下并且在项目级别下的gradle里添加

flatDir{
            dirs 'libs'
 }

在依赖里添加 PS： alipaySdk-15.6.2-20190416165036 换成自己arr的名字

implementation(name: 'alipaySdk-15.6.2-20190416165036', ext: 'aar')

在清单文件里加入权限

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

MainActivity代码里面有注释

public class MainActivity extends AppCompatActivity implements Response.ErrorListener, Response.Listener<String> {

    private static final String TAG = "MainActivity";

    private static final int SDK_PAY_FLAG = 10;
    private Button payFor;
    //post请求,token,金额,应用版本号,操作系统系统
    private String mUrl = "http://api.banmi.com/api/app/v3/payments/alipay";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        iniper();
        initView();
    }

    private void iniper() {
        String[] per = {Manifest.permission.READ_PHONE_STATE,
                Manifest.permission.WRITE_EXTERNAL_STORAGE};

        ActivityCompat.requestPermissions(this,per,100);
    }

    private void initView() {
        payFor = (Button) findViewById(R.id.payFor);
        payFor.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                aliPay();
                Toast.makeText(MainActivity.this, "", Toast.LENGTH_SHORT).show();
            }
        });
    }

    private void aliPay() {

        // 1.请求自己家的服务器 商品id 用户id 商品价格 商品数量
        RequestQueue queue = Volley.newRequestQueue(this); //请求队列
        StringRequest request = new StringRequest(Request.Method.POST, mUrl, this, this){
            @Override
            protected Map<String, String> getParams() throws AuthFailureError {
                ArrayMap<String, String> map = new ArrayMap<>();
                map.put("amount","1.0");
                map.put("token","mKVoQRrXlMvmfWbgWzyDYHF1KOUN5e4bwWrOiab9tZ8sWIQAZmg48lSa2NOORqpko6V0l4cYCs1Uip23M6MglE6Xp6LvHKO9RUNP4m8pHjp1zHb8nmK1bU1pvRp2LFkwA");
                map.put("version","3.3.3");
                map.put("os","android");
                return map;
            }
        };
        queue.add(request); // ☆ 发起请求

    }

    // 成功回调
    @Override
    public void onResponse(String s) {
        Log.i(TAG, "onErrorResponse: "+s);
        // 2.解析自己服务器返回的数据 拿到支付串码
        Gson gson = new Gson();
        AliPayBean aliPayBean = gson.fromJson(s, AliPayBean.class);

                // 3.调用支付宝的SKD,拉起支付界面
         callAliSdk(aliPayBean);


    }

    private void callAliSdk(AliPayBean aliPayBean) {
        final String orderInfo = aliPayBean.getResult().getSign();   // 订单信息

        Runnable payRunnable = new Runnable() {
            @Override
            public void run() {
                PayTask alipay = new PayTask(MainActivity.this);
                Map<String,String> result = alipay.payV2(orderInfo,true);

                Message msg = new Message();
                msg.what = SDK_PAY_FLAG;
                msg.obj = result;
                mHandler.sendMessage(msg);
            }
        };
        // 必须异步调用
        Thread payThread = new Thread(payRunnable);
        payThread.start();
    }

    //4.处理支付宝app返回的支付结果
    @SuppressLint("HandlerLeak")
    private Handler mHandler = new Handler() {
        public void handleMessage(Message msg) {
            switch (msg.what) {
                case SDK_PAY_FLAG: {
                    @SuppressWarnings("unchecked")
                    PayResult payResult = new PayResult((Map<String, String>) msg.obj);
                    /**
                     * 对于支付结果，请商户依赖服务端的异步通知结果。同步通知结果，仅作为支付结束的通知。
                     */
                    String resultInfo = payResult.getResult();// 同步返回需要验证的信息
                    String resultStatus = payResult.getResultStatus();
                    // 判断resultStatus 为9000则代表支付成功
                    if (TextUtils.equals(resultStatus, "9000")) {
                        // 该笔订单是否真实支付成功，需要依赖服务端的异步通知。
                        showToast("支付成功:"+payResult);
                        Log.d(TAG, "支付成功: "+payResult+",resultInfo:"+resultInfo);
                    } else {
                        // 该笔订单真实的支付结果，需要依赖服务端的异步通知。
                        showToast("支付失败:"+payResult);
                        Log.d(TAG, "支付失败: "+payResult+",resultInfo:"+resultInfo);
                    }
                    break;
                }

                default:
                    break;
            }
        };
    };

    // 失败回调
    @Override
    public void onErrorResponse(VolleyError volleyError) {

    }

    public void showToast(String msg){
        Toast.makeText(this,msg,Toast.LENGTH_SHORT).show();
    }

}

把Bean类和接口回调也给大家

此处圈重点

如果你是安卓9.0的用户需要在清单文件中加入

<application
        ....
    //加xml文件
        android:networkSecurityConfig="@xml/network_security_config"
        android:theme="@style/AppTheme">
        .....
</application>

@xml/network_security_config

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <base-config cleartextTrafficPermitted="true" />
</network-security-config>
