requestWindowFeature（Window.FEATURE_NO_TITLE）;导致应用程序崩溃？ [英] requestWindowFeature(Window.FEATURE_NO_TITLE); causing the App to crash?

问题描述

应用crashs当我加入这行

`requestWindowFeature（Window.FEATURE_NO_TITLE）;

可能是解决的方法很简单，但我真的不知道谁解决它。

Java的code：

 公共类GLSurfaceCameraSurfaceDemo2Activity延伸活动{
/ **当第一次创建活动调用。 * /GLSurfaceView glSurfaceView;
的FrameLayout FL01;@覆盖
公共无效的onCreate（捆绑savedInstanceState）{
    super.onCreate（savedInstanceState）;
    的setContentView（R.layout.main）;    requestWindowFeature（Window.FEATURE_NO_TITLE）;}
 

}

XML文件：

 ＆LT;的FrameLayout
        机器人：ID =@ + ID / FL01
        机器人：方向=横向
        机器人：layout_width =FILL_PARENT
        机器人：layout_height =FILL_PARENT/＆GT;
 

解决方案

您必须调用requestWindowFeature（Window.FEATURE_NO_TITLE）;的setContentView（）之前...

 公共类GLSurfaceCameraSurfaceDemo2Activity延伸活动{
/ **当第一次创建活动调用。 * /GLSurfaceView glSurfaceView;
的FrameLayout FL01;@覆盖
公共无效的onCreate（捆绑savedInstanceState）{
    super.onCreate（savedInstanceState）;
    requestWindowFeature（Window.FEATURE_NO_TITLE）;
    的setContentView（R.layout.main）;}
 

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"/>  

解决方案

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);

}
