Android 微信支付，授权，分享回调区分记录

private IWXAPI api;  

@Override  
    protected void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);  
        api = WXAPIFactory.createWXAPI(this, AppContant.APP_ID);  
        api.handleIntent(getIntent(), this);  
    }  
  
    @Override  
    protected void onNewIntent(Intent intent) {  
        super.onNewIntent(intent);  
        setIntent(intent);  
        api.handleIntent(intent, this);  
    }  

然后就是实现接口中的onResp方法中来接收回调的消息。

下面看下代码：

@Override  
    public void onResp(BaseResp resp) {  
        if (resp.getType() == ConstantsAPI.COMMAND_PAY_BY_WX) {  // 支付  
            int errCode = resp.errCode;  
            if (errCode == -1) {  
                Toast.makeText(getApplicationContext(), resp.errStr, Toast.LENGTH_SHORT).show();  
            } else if (errCode == 0) {  
                Toast.makeText(getApplicationContext(), "支付完成", Toast.LENGTH_SHORT).show();  
            } else {  
                Toast.makeText(getApplicationContext(), "支付失败", Toast.LENGTH_SHORT).show();  
            }  
        }else if (resp.getType()==ConstantsAPI.COMMAND_SENDMESSAGE_TO_WX){ // 分享  
            int result = 0;  
            switch (resp.errCode) {  
                case BaseResp.ErrCode.ERR_OK:  
                    result = 分享成功;  
                    break;  
                case BaseResp.ErrCode.ERR_USER_CANCEL:  
                    result = 取消分享;  
                    break;  
                case BaseResp.ErrCode.ERR_SENT_FAILED:  
                    result = 分享失败;  
                    break;  
                default:  
                    result = 未知原因;  
                    break;  
            }  
            Toast.makeText(getApplicationContext(), getString(result), Toast.LENGTH_SHORT).show(); 
        }else if(resp.getType()==ConstantsAPI.COMMAND_SENDAUTH){  // 登录
            int result = 0;  
            switch (resp.errCode) {  
                case BaseResp.ErrCode.ERR_OK:  
                    // 授权成功  
                    result = R.string.wechat_login_success;  
                    // 发送事件通知登陆界面  
                    EventBus.getDefault().post(resp);  
                    break;  
                case BaseResp.ErrCode.ERR_USER_CANCEL:  
                    // 授权取消  
                    result = 取消授权;  
                    break;  
                case BaseResp.ErrCode.ERR_AUTH_DENIED:  
                    // 授权被拒绝  
                    result = 授权被拒绝;  
                    break;  
                default:  
                    // 未知错误  
                    result = 未知原因;  
                    break;  
            }  
            Toast.makeText(getApplicationContext(), getString(result), Toast.LENGTH_SHORT).show();  
            finish();  
        }  
    }
