##导入说明(import):
在build.gradle直接引用 :
dependencies {
compile 'com.github.SmileFei:AndroidPayLibrary:v2.0.0'
}
注意在Project的build.gradle中添加如下代码
allprojects {
repositories {
jcenter()
maven { url 'https://jitpack.io' }
}
##使用说明(Usage):
1、支付宝
AliPayFromServer alipay = new AliPayFromServer.Builder().
with(PaySelectActivity.this).
create().
setOnAliPayListener(new AliPayFromServer.OnAliPayListener() {
@Override
public void onPaySuccess(String resultInfo) {
}
@Override
public void onPayFailure(String resultInfo) {
}
@Override
public void onPayConfirmimg(String resultInfo) {
}
});
alipay.send(payInfoServer);
2、微信支付
public void weChatPay() {
//1.创建微信支付请求
WechatPayReq wechatPayReq = new WechatPayReq.Builder()
.with(this) //activity实例
.setAppId(response.getAppId()) //微信支付AppID
.setPartnerId(response.getPartnerId())//微信支付商户号
.setPrepayId(response.getPrepayId())//预支付码
.setNonceStr(response.getNonceStr())
.setPackageValue(response.getPackageStr())
.setTimeStamp(response.getTimeStamp())//时间戳
.setSign(response.getSign())//签名
.create();
//2.发送微信支付请求
PayAPI.getInstance().sendPayRequest(wechatPayReq);
//3.关于微信支付的回调
在"App包名.wxapi"的package中新建WXPayEntryActivity 如下所示,在onResp()方法中执行回调
}
public class WXPayEntryActivity extends Activity implements IWXAPIEventHandler {
private static final String TAG = "==============WXPayEntryActivity==============";
private IWXAPI api;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
api = WXAPIFactory.createWXAPI(this, Constant.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 req) {
BaseReq abc = req;
}
@Override
public void onResp(BaseResp resp) {
Log.e(TAG, "checkArgs=" + resp.checkArgs());
if (resp.getType() == ConstantsAPI.COMMAND_PAY_BY_WX) {
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("提示");
builder.setMessage("微信支付结果:" + "errCode=" + resp.errCode + "; errStr=" + resp.errStr);
builder.show();
}
}
}
3、银联支付
//步骤1:app这边将购买的商品信息提交给app后台,app后台接收到购买信息之后,将信息提交给银联后台,
银联接收到支付信息给app后台返回一个交易流水号(tn)
...
//步骤2:通过银联工具类启动支付插件
UPPayAssistEx.startPay(MainActivity.this, null, null, tn, mMode);
//步骤3:调用银联支付后,返回给app支付状态的回调
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// 处理银联手机支付控件返回的支付结果
if (data == null) {
return;
}
String msg = "";
/*
* 支付控件返回字符串:success、fail、cancel 分别代表支付成功,支付失败,支付取消
*/
String str = data.getExtras().getString("pay_result");
if (str.equalsIgnoreCase("success")) {
// 如果想对结果数据验签,可使用下面这段代码,但建议不验签,直接去商户后台查询交易结果
// result_data结构见c)result_data参数说明
if (data.hasExtra("result_data")) {
String result = data.getExtras().getString("result_data");
try {
JSONObject resultJson = new JSONObject(result);
String sign = resultJson.getString("sign");
String dataOrg = resultJson.getString("data");
// 此处的verify建议送去商户后台做验签
// 如要放在手机端验,则代码必须支持更新证书
boolean ret = verify(dataOrg, sign, mMode);
if (ret) {
// 验签成功,显示支付结果
msg = "支付成功!";
} else {
// 验签失败
msg = "支付失败!";
}
} catch (JSONException e) {
}
}
// 结果result_data为成功时,去商户后台查询一下再展示成功
msg = "支付成功!";
} else if (str.equalsIgnoreCase("fail")) {
msg = "支付失败!";
} else if (str.equalsIgnoreCase("cancel")) {
msg = "用户取消了支付";
}
}
