【问题描述】：

添加此行时应用程序崩溃

`requestWindowFeature(Window.FEATURE_NO_TITLE);

可能解决方法很简单，但我真的不知道该找谁解决。

Java 代码：

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"/>

【问题讨论】：

你必须调用 requestWindowFeature(Window.FEATURE_NO_TITLE);在 setContentView() 之前。

你必须调用 requestWindowFeature(Window.FEATURE_NO_TITLE);在 setContentView() 之前...

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);

}

【解决方案2】：

只要这样做：

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

    setContentView(R.layout.main);

}

你必须在super.onCreate(savedInstanceState);之前声明requestWindowFeature(Window.FEATURE_NO_TITLE);
