requestWindowFeature（Window.FEATURE_NO_TITLE）;導致應用程序崩潰？

Question

當我添加此行時，應用程序崩潰

`requestWindowFeature（Window.FEATURE_NO_TITLE）;

可能是解決方案非常簡單，但我真的不知道誰來解決它。

Java代碼：

public class GLSurfaceCameraSurfaceDemo2Activity extends Activity { 
/** Called when the activity is first created. */ 

GLSurfaceView glSurfaceView; 
FrameLayout fl01; 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 

    requestWindowFeature(Window.FEATURE_NO_TITLE); 

} 

}

XML文件：

<FrameLayout 
     android:id="@+id/fl01" 
     android:orientation="horizontal" 
     android:layout_width="fill_parent" 
     android:layout_height="fill_parent"/> 

Answer 1

必須調用requestWindowFeature（Window.FEATURE_NO_TITLE）;的setContentView（）...

public class GLSurfaceCameraSurfaceDemo2Activity extends Activity { 
/** Called when the activity is first created. */ 

GLSurfaceView glSurfaceView; 
FrameLayout fl01; 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    requestWindowFeature(Window.FEATURE_NO_TITLE); 
    setContentView(R.layout.main); 

} 

Answer 2

只是這樣做之前：

@Override 
public void onCreate(Bundle savedInstanceState) { 
    requestWindowFeature(Window.FEATURE_NO_TITLE); 
    super.onCreate(savedInstanceState); 

    setContentView(R.layout.main); 

} 

必須前super.onCreate(savedInstanceState);
