队第一个活动后关闭

问题描述：

我有我的第一个应用程序的一些问题..队第一个活动后关闭

上有错误日志中，SplashActivity（我测试的介绍）和FullscreenActivity，我就开始intent = new Intent(SplashActivity.this, FullscreenActivity.class);但后来我收到一个FC和大错误日志。我缩短了一下，如果需要完整的日志，我可以发表评论或更新线程！

希望你能帮助我，我搜索了几个小时，但没有找到一个解决方案..

好心认为

'mContentView.setOnClickListener'你期望做什么？ – njzk2

好问题，这是AS的inizialist ..这是我第一次尝试AS。 – svansolo

答

mContentView为空。

在onclick函数之前。您需要将mContentView定义为您正在使用的任何布局。

例如

mContentView = (RelativeLayout) findViewById(R.id.thisisidoflayout);

感谢您的快速帮助！其中一个问题已解决，您是否对 “Firebase Api初始化失败”有所了解。和 “E/FA：工作线程上的任务异常：[...]” ？ :) – svansolo

同样的事情。就像卡尔朋先生所说，问题在于初始化。尝试阅读firebase。一旦你得到它。对你来说很容易。 –

答

你的一个观点在FullScreenActivity为空。

mContentView.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      toggle(); 
     } 
    });

mContentView从未初始化。

mContentView =（RelativeLayout）findViewById（R.id.mContentViewID）; – Remario
