android支付宝,微信支付集成工具类
详细的介绍、解释移步微信、支付宝的开发平台。下载官方demo了解更多。需要注意的是,微信的官方demo还是eclipse版的。
实现步骤
1.添加相关的引用(微信,支付宝)
主要是在libs目录下,添加支付宝sdkjar包,同时在gradle文件中添加依赖。如下图所示

微信支付需要创建一个包名为wxapi,并且必须放置在applicationId下面,随便放到一个包下的话,会导致支付之后,拿不到回调,如下图

image.png WXPayEntryActivity,主要是对onResp()的方法重写,参见官方的demo,自己的全部代码为:
package com.example.user.paydemo.wxapi;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.os.Handler;
import android.support.annotation.Nullable;
import android.support.v7.app.AppCompatActivity;
import android.widget.RelativeLayout;
import com.example.user.paydemo.AppManager;
import com.example.user.paydemo.MainActivity;
import com.example.user.paydemo.PayUtils;
import com.tencent.mm.opensdk.modelbase.BaseReq;
import com.tencent.mm.opensdk.modelbase.BaseResp;
import com.tencent.mm.opensdk.modelpay.PayResp;
import com.tencent.mm.opensdk.openapi.IWXAPI;
import com.tencent.mm.opensdk.openapi.IWXAPIEventHandler;
import com.tencent.mm.opensdk.openapi.WXAPIFactory;
/**
* 微信回调页面
*/
public class WXPayEntryActivity extends AppCompatActivity implements IWXAPIEventHandler {
private IWXAPI api;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(new RelativeLayout(this));
api = WXAPIFactory.createWXAPI(this, PayUtils.WECHAT_APP_ID);
api.handleIntent(getIntent(), this);
}@Override
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);
setIntent(intent);
api.handleIntent(intent, this);
}@Override
public void onReq(BaseReq baseReq) {
}
@Override
public void onResp(BaseResp baseResp) {
int code = baseResp.errCode;
//LogUtils.LOG_D(PayUtils.class, "返回的code=" + code);
PayResp payResp = (PayResp) baseResp;
switch (code) {
case 0://支付成功后的界面
paySucess(payResp);
finish();
break;
case -1:
//showToast("签名错误、未注册APPID、项目设置APPID不正确、注册的APPID与设置的不匹配、您的微信账号异常等。");
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
finish();
}
}, 1500);
break;
case -2://用户取消支付后的界面
//mPresenter.payCancle();
取消支付处理方法类似paySucess()
finish();
break;
}
}private void paySucess(PayResp payResp) {
//从activity栈中取出需要支付页面
Activity activity = AppManager.getBaseActivity(MainActivity.class);
if (activity != null && !activity.isFinishing()) {
MainActivity payActivity = (MainActivity) activity;
payActivity.wxPaySuccess(payResp);
}
}
}
至此,支付宝和微信的配置就完成了。
接下来是配置支付工具类了。目录结构如下:
文章图片
image.png AlipayEntity全部代码:
package com.example.user.paydemo.bean;
import com.google.gson.annotations.Expose;
/**
* 调起支付宝支付的实体类
*/
public class AlipayEntity {
@Expose
private String orderstring;
@Expose

return this;
}
public String getOrderid() {
return orderid;
}
public AlipayEntity setOrderid(String orderid) {
this.orderid = orderid;
return this;
}
}
WxPayEntity 全部代码:
package com.example.user.paydemo.bean;

/***

public class WxPayEntity implements Serializable{
@Expose

@Expose
private String orderid;
@Expose
private String noncestr;
@Expose
private String timestamp;
@Expose

@SerializedName("package")
private String packageName = "Sign=WXPay";
//固定写死public String getPrepay_id() {

return this;
}public String getTimestamp() {

}public WxPayEntity setTimestamp(String timestamp) {
this.timestamp = timestamp;
return this;
}public String getSign() {
return sign;
}public WxPayEntity setSign(String sign) {
this.sign = sign;
return this;
}public String getPackageName() {
return packageName;
}public WxPayEntity setPackageName(String packageName) {
this.packageName = packageName;
return this;
}
}
PayZfbResultEntity代码:

/**

*/
public class PayZfbResultEntity {
public PayResult payResult;
public String orderid;
}
PayResult代码:
package com.example.user.paydemo.bean;
import android.text.TextUtils;

public class PayResult {
private String resultStatus;
private String result;
private String memo;
public PayResult(Map rawResult) {

return;
}for (String key : rawResult.keySet()) {

} 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 + "}";
}/**

*/
public String getResultStatus() {

payutils的用法,MainActivity的代码:
在调用支付之前一定要将app注册到微信中,即执行:api.registerApp(); 这个方法
调用支付宝支付的方法
payUtils.payByAliPay(alipayEntity);
需要注意的是传入的参数是服务器返回的支付宝数据的数据实体类,服务器返回的支付宝数据格式应该如下:(即message字段的数据内容通过json转换bean对象)

payUtils.payByWechat(wxPayEntity);
需要注意的是传入的参数,需要为服务器返回的微信支付数据的实体对象。服务器返回的格式应如下:(同样是将message字段部分转换成为bean对象)

【android支付宝,微信支付集成工具类】demo链接地址(无法运行,无法运行,无法运行,只是记录了主要的步骤)
存在这么一种情况,当用户通过杀死进程的方法关闭支付的页面回到app端的时候,我们无法获取到手机的支付状态,这个时候我们就需要后台提供一个接口,来告诉app是否支付成功。
