1.WXEntryActivity 类
public class WXEntryActivity extends Activity implements IWXAPIEventHandler { private static final String WECHAT_APPID = "我的appid"; private IWXAPI api; @Override protected void onCreate(@Nullable Bundle savedInstanceState) { super.onCreate(savedInstanceState); api = WXAPIFactory.createWXAPI(this, WECHAT_APPID); 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) { Toast.makeText(this, "onReq 1500", Toast.LENGTH_SHORT).show(); } @Override public void onResp(BaseResp baseResp) { ToastUtils.showShort(" 微信支付返回码"+baseResp.errCode); LogUtils.d("1923 返回码" + baseResp.errCode); if (baseResp.getType() == ConstantsAPI.COMMAND_PAY_BY_WX) { AlertDialog.Builder builder = new AlertDialog.Builder(this); builder.setTitle("支付结果"); builder.setMessage(String.valueOf(baseResp.errCode)); builder.show(); } }} |
2.支付代码:
private void wechatPay(WechatPayBean bean) { String appid = bean.getAppid();//appid String mch_id = bean.getMch_id();//商户号 String prepay_id = bean.getPrepay_id();//预支付交易会话ID String nonce_str = bean.getNonce_str();//随机字符串 String time_stamp = bean.getTime_stamp();//时间戳// String sign = bean.getSign();//签名 IWXAPI api = WXAPIFactory.createWXAPI(OrderConfirmActivity.this, appid, false);//填写自己的APPIDapi.registerApp("wxAPPID");//填写自己的APPID，注册本身 api.registerApp(appid); PayReq req = new PayReq();//PayReq就是订单信息对象 req.appId = appid;//你的微信appid req.partnerId = mch_id;//商户号 req.prepayId = prepay_id;//预支付交易会话ID req.nonceStr = nonce_str;//随机字符串 req.timeStamp = time_stamp;//时间戳 req.packageValue = "Sign=WXPay";//扩展字段,这里固定填写Sign=WXPay //todo:sign必须由appId等六个值拼接而成 req.sign = bean.getSign();//签名 api.sendReq(req);//将订单信息对象发送给微信服务器，即发送支付请求req.timeStamp));// req.sign = getSign(list);//签名 } |
3.清单文件注册:
<activity android:name=".wxapi.WXEntryActivity" android:label="@string/app_name" android:theme="@android:style/Theme.Translucent.NoTitleBar" android:exported="true" android:taskAffinity="我的包名" android:launchMode="singleTask"> </activity> |
我也是支付成功但是没有回调。。。怎么办呢？
楼主解决了吗，遇到相同问题，一直未找打原因
失败是没有回调的，只有支付成功才会有。
