所以我在我的Android應用上遇到異常，我不知道從哪裏來。是的，我的代碼現在是一個完整的混亂，現在試圖解決它。setContentView異常（R.layout.activity_main）;

不知何故，我的setcontentview指向某處null，但我真的不知道在哪裏和爲什麼。

MainActivity.java

       Log.d("facebook name", profile.getFirstName()); 

      } 

      @Override

      } 

      @Override

// Remember that you should never show the action bar if the

     ActionBar actionBar = getActionBar(); 
     actionBar.hide(); 

    }

在錯誤顯然是提到： 「的SDK尚未初始化，請務必先調用FacebookSdk.sdkInitialize（）」，所以前設置該視圖做到這一點 –

@NicklasN：嘗試FacebookSdk.sdkInitialize（this）;而不是FacebookSdk。sdkInitialize（getApplicationContext（））; – AndiGeeky

嘿，我不知道它，但你可以寫** Parse.initialize（這，「EsOSbCtBvwx6S2ZojAP3JWh7TcNiy5czMguNMYmh」，「nLUoS1u1408ZYUt6YZFeiPvZz0iI0WPncjvnmh0h」）; **剛剛超級（）;方法。 –

你的printStackTrace明確指出Error inflating class com.facebook.login.widget.LoginButton

您使用自定義窗口小部件com.facebook.login.widget.LoginButton經過它的文檔，並檢查您的充氣

檢查this問題

認沽以下行：

FacebookSdk.sdkInitialize(getApplicationContext());

此的setContentView（）之前

我編輯的OnCreate此;

@Override 
    protected void onCreate(Bundle savedInstanceState) { 

     FacebookSdk.sdkInitialize(this); 
     Parse.initialize(this, "KEY", "KEY"); 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     ParseFacebookUtils.initialize(this);

而且現在的工作..

堆棧跟蹤是相當清楚的：

Caused by: The SDK has not been initialized, make sure to call FacebookSdk.sdkInitialize() first.

需要調用

FacebookSdk.sdkInitialize(getApplicationContext());

前

setContentView(R.layout.activity_main);

您的堆棧跟蹤狀態

The SDK has not been initialized, make sure to call FacebookSdk.sdkInitialize() first.

爲FacebookSdk參見文檔：

這個函數初始化的Facebook SDK，Facebook的SDK函數的行爲是不確定的，如果這個功能沒有被調用。它應該儘可能早地被調用。

所以只要將相關的初始化了

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    Parse.initialize(this, "KEY", "KEY"); 
    ParseFacebookUtils.initialize(this); 
    FacebookSdk.sdkInitialize(getApplicationContext()); 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    [...] 
}
