已在清单文件注册WXEntryActivity,下面是调起支付,清单文件注册,回调的代码
1.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>

2.调起支付的函数:

 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

        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

        mWechatApi.sendReq(req);//将订单信息对象发送给微信服务器，即发送支付请求

    }

3.回调类:

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();

        }

    }

}
