requestWindowFeature(Window.FEATURE_NO_TITLE); cau

2019-01-29 01:12发布

The App crashs when I add this line

`requestWindowFeature(Window.FEATURE_NO_TITLE);

may be the solution is very simple, but i really dont know who to fix it.

Java code:

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 File:

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

just do this :

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

    setContentView(R.layout.main);

}

you must declar requestWindowFeature(Window.FEATURE_NO_TITLE); before super.onCreate(savedInstanceState);

you must call requestWindowFeature(Window.FEATURE_NO_TITLE); before 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);

}
