Android.Views.InflateException：二进制XML文件行＃1：在SetContentView上输出类<unknown>时出错

时间：2018-05-31 17:47:45

标签： c# android visual-studio xamarin exception

我正在开发一个C＃android应用程序，它包含3个活动和3个布局。主要活动包括3个按钮，每个按钮将用户传递到特定的应用程序。第一个按钮转到FirstAct，它包含一些textViews和一个将用户重新加入MainActivity的按钮。现在单击返回按钮后，我重新单击MainActivity中的第一个按钮，将抛出此异常。

FirstAct.cs 

protected override void OnCreate(Bundle savedInstanceState)
{
    base.OnCreate(savedInstanceState);
    try
    {
        SetContentView(Resource.Layout.FirstLay);
        reBtn.Click += delegate
        {
            StartActivity(typeof(MainActivity));
        };
    }
    catch (Java.Lang.Exception ex)
    {
        Toast.MakeText(this, ex.ToString(), ToastLength.Short).Show();
    }
 }

奇怪的是，当我第一次在Mainactivity中单击该按钮时，第一个活动仅在第二次抛出异常时才会启动而没有问题。我首先想到的是，我所拥有的背景图像可能会导致这种情况，所以我将其删除了，但这并没有奏效。然后我放了NoHistory = true但也没用。此外，我还尝试在单击返回按钮时启动MainActivity之前完成活动。所以我不知道是什么导致了这个问题，请你帮我找一下？
