Question

嗨我在片段中遇到了android gridview的问题。我有搜索解决方案但没有成功，也许在这里我得到了解决这个问题。谢谢。我的代码是：

@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.frontpage, container, false);
        createGridCategory(inflater, view);
        return view;
    }

    public void createGridCategory(LayoutInflater inflater, View container) {
        AdapterView<ListAdapter> itemsGridViewObj = (GridView) container.findViewById(R.id.newsScrollerContent);

        categoryNames = database.getEnabledCategories()[1];
        physicalCategories = new ArrayList<RelativeLayout>(categoryNames.length);
        physicalItems = new ItemLayout[categoryNames.length][categoryRowLength]; 

        // loop through adding category views
        for (int i = 0; i < categoryNames.length; i++) {
            RelativeLayout categoryTitleBar = (RelativeLayout) inflater
                    .inflate(R.layout.list_category_item, null);

            categoryTitleBar.setOnClickListener(new View.OnClickListener() {
                public void onClick(View view) {
                    int id = physicalCategories.indexOf(view);
                    clickHandler.onCategoryClick(categoryNames[id]);
                }
            });

            TextView name = (TextView) categoryTitleBar
                    .findViewById(R.id.categoryTitle);
            name.setText(categoryNames[i]);

            physicalCategories.add(i, categoryTitleBar);
            itemsGridViewObj.addView(categoryTitleBar);
        }
    }

/res/layout/frontpage.xml中的布局

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/newsScroller"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#F5F5F5" >   

   <GridView
        android:id="@+id/newsScrollerContent"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:horizontalSpacing="10dp"
        android:numColumns="auto_fit"
        android:verticalSpacing="10dp" >
    </GridView>

</ScrollView>

/res/layout/list_category_item.xml中的

布局

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/categoryTitleBar"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:paddingBottom="7dp"
    android:paddingLeft="7dp"
    android:paddingRight="7dp"
    android:paddingTop="7dp" >

    <TextView
        android:id="@+id/categoryTitle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="No Title"
        android:textSize="17sp" />


</RelativeLayout>

如果我在logcat中看错了：
