Question

当我添加此行时，应用程序崩溃

`requestWindowFeature（Window.FEATURE_NO_TITLE）;

可能解决方案非常简单，但我真的不知道该修复它。

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"/>

Answer 1

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);

}

Answer 2

这样做：

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

    setContentView(R.layout.main);

}

您必须在requestWindowFeature(Window.FEATURE_NO_TITLE);

之前声明super.onCreate(savedInstanceState);

requestWindowFeature（Window.FEATURE_NO_TITLE）;导致应用程序崩溃？
