晚上好,

我正在尝试在我的 Android 应用程序中使用亚马逊的新广告服务,遵循他们的指导方针让我到目前为止,但我无法摆脱一个错误......

有错误的代码是

// Programmatically create the AmazonAdLayout       
        this.adView = new AdLayout(this, AdLayout.AdSize.AD_SIZE_320x50);
        LinearLayout layout = (LinearLayout) findViewById(R.id.mainLayout);

            // If you declared AdLayout in your xml you would instead
            // replace the 3 lines above with the following line
            // this.adView = (AdLayout) findViewById( R.id.adview );

            this.adView.loadAd(new AdTargetingOptions()); // async task to retrieve an ad

错误在线

LinearLayout 布局 = (LinearLayout) findViewById(R.id.mainLayout);

'mainLayout 无法解析或不是字段'

我想不明白?有 Eclipse 知识的人可以帮忙吗?:)
