setContentView上的非法狀態異常

當調用setContentView()時，我在onCreate()方法中有IllegalStateException。setContentView上的非法狀態異常

在某些特定設備上發生異常。大多數情況下，在Android 4.4版設備上。在其他設備上正常工作。

的onCreate（）：

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    viewPager = (ViewPager)findViewById(R.id.viewpager); 
    tabLayout = (TabLayout)findViewById(R.id.sliding_tabs); 

    CategoryAdapter categoryAdapter = new CategoryAdapter(this, getSupportFragmentManager()); 
}

佈局：

<android.support.v4.widget.DrawerLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
