RxPay

本项目实现支付宝、微信支付。

基于 Vinctor/RxPay 修改实现，感谢原作者。有如下不同：

• 支持RxJava2。

• 对支付结果的二次封装。

RxPay的优点：

• 使用简单、清晰。

• 不需要编写WXPayEntryActivity类以及声明微信要求的广播类AppRegister。

使用方式

添加依赖

    compile ('com.github.simplezhli.RxPay:pay-api:v1.0.8'){
        exclude module: 'appcompat-v7'
    }
    annotationProcessor 'com.github.simplezhli.RxPay:pay-compiler:v1.0.8'

支付宝

   new RxAliPay()
           .with(MainActivity.this, sign) //服务器端返回签名
           .requestPay()
           .subscribe(new Observer<PayResult>() {
                 @Override
                 public void onSubscribe(Disposable d) {}
   
                 @Override
                 public void onNext(PayResult payResult) {
                       Toast.makeText(MainActivity.this, "支付成功！" , Toast.LENGTH_SHORT).show();
                 }
   
                 @Override
                 public void onError(Throwable e) {
                       Log.e("ErrCode:", ((PayFailedException)e).getErrCode());
                       Toast.makeText(MainActivity.this, e.getMessage(), Toast.LENGTH_SHORT).show();
                 }
   
                 @Override
                       public void onComplete() {}
                 });        
           

微信

1.在你自定义的Application中初始化

   RxWxPay.init(this);

2.对你任意一个activity类进行如下注解：

   @WXPay(BuildConfig.APPLICATION_ID)
   public class MainActivity extends AppCompatActivity {
   }

之后Make Project

3.AndroidManifest.xml加入

    <activity
          android:name=".wxapi.WXPayEntryActivity"
          android:exported="true"
          android:launchMode="singleTop"
          android:screenOrientation="portrait" />

4.调用方法

   RxWxPay.WXPayBean payBean = new RxWxPay.WXPayBean("appid", "partnerid", "noncestr",
           "timestamp", "prepayid", "sign");
   
   RxWxPay.getInstance()
          .withWxPayBean(payBean)
          .requestPay()
          .subscribe(new Observer<WxPayResult>() {
                 @Override
                 public void onSubscribe(Disposable d) {}
   
                 @Override
                 public void onNext(WxPayResult wxPayResult) {
                       Toast.makeText(MainActivity.this, "支付成功！" , Toast.LENGTH_SHORT).show();
                 }
   
                 @Override
                 public void onError(Throwable e) {
                        Log.e("ErrCode:", ((PayFailedException)e).getErrCode());
                        Toast.makeText(MainActivity.this, e.getMessage(), Toast.LENGTH_SHORT).show();
                 }
   
                 @Override
                       public void onComplete() {}
                 });

5.注意

防止内存泄露，记得要取消订阅。

     @Override
    protected void onDestroy() {
        super.onDestroy();
        RxWxPay.getInstance().onDestroy();
    }
