我创建了xml布局文件.当我把它作为内容提供给我的活动时,标题栏是不可见的.我怎样才能让它可见我试着用setTitle(“Title”);

protected void onCreate(Bundle savedInstanceState) {

getWindow().addFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);

getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);

super.onCreate(savedInstanceState);

Bundle b = getIntent().getExtras();

int layoutId = b.getInt("layout");

Log.d("====>>>", " " + layoutId);

setContentView(layoutId);

setTitle("Title");

}

onCreate()方法中的函数.我不工作.这是我的xml文件.

android:id="@+id/ScrollView01"

android:layout_width="fill_parent"

android:layout_height="fill_parent" >

xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"

android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"

android:paddingRight="@dimen/activity_horizontal_margin"

android:paddingTop="@dimen/activity_vertical_margin"

android:paddingBottom="@dimen/activity_vertical_margin"

tools:context="com.universityapp.enrollee.FacultyInformationActivity"

android:scrollbars="vertical"

>

android:layout_width="fill_parent"

android:layout_height="fill_parent"

android:text="@string/text_faculty_information_agro"

android:textSize="15dp"

android:textAlignment="center"

/>

我通过ListView启动活动：

profListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {

@Override

public void onItemClick(AdapterView> parent, View view, int position, long id) {

switch (position){

case 0:

facultyInfoIntent = new Intent(getBaseContext(), FacultyInformationActivity.class);

Bundle b = new Bundle();

b.putInt("layout", facultyLayoutNames[position]);

facultyInfoIntent.putExtras(b);

startActivity(facultyInfoIntent);

}

Log.d("Selected faculty", facultiNames[position]);

}

});

这是我的清单：
