Question

Result.java：

Fragment f = new GridViewFragement();
FragmentManager fm = getFragmentManager();

fm.beginTransaction().replace(R.id.grid, f).commit();

Activity_result.xml：

   <LinearLayout
       android:layout_width="wrap_content"
      android:layout_height="match_parent"
      android:id="@+id/grid"
       android:orientation="vertical"

    >

</LinearLayout>

Row_grid.xml：定义网格项

 <LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
   xmlns:tools="http://schemas.android.com/tools"
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
  android:orientation="vertical"
   android:padding="5dp" >

  <ImageView

    android:id="@+id/item_image"
    android:layout_width="50dp"
    android:layout_height="50dp"
    android:layout_marginRight="10dp"
    android:src="@drawable/home" >
 </ImageView>

 <TextView
    android:id="@+id/item_text"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginTop="5dp"
    android:textSize="15sp" >
 </TextView>

</LinearLayout>

grid.xml：

         <GridView
        android:id="@+id/gridView1"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_margin="4dp"
        android:columnWidth="80dp"
        android:gravity="center"
        android:numColumns="auto_fit"
        android:stretchMode="columnWidth"
        android:fadeScrollbars="false"
       />

在网格视图片段中创建：

       public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        // on create for activity


        View view = inflater.inflate(R.layout.grid, container, false);
        Bitmap homeIcon = BitmapFactory.decodeResource
        (this.getResources(), R.drawable.home);
        Bitmap userIcon = BitmapFactory.decodeResource
        (this.getResources(),   R.drawable.personal);
        //
        gridArray.add(new Item(homeIcon,"Home"));
        gridArray.add(new Item(userIcon,"Personal"));
        gridArray.add(new Item(homeIcon,"Home"));
        gridArray.add(new Item(userIcon,"User"));
        gridArray.add(new Item(homeIcon,"Building"));
        gridArray.add(new Item(userIcon,"User"));
        gridArray.add(new Item(homeIcon,"Home"));
        gridArray.add(new Item(userIcon,"xyz"));
        gridArray.add(new Item(homeIcon,"Home"));
        gridArray.add(new Item(userIcon,"User"));
        gridArray.add(new Item(homeIcon,"House"));
        gridArray.add(new Item(userIcon,"Friend"));



        gridView = (GridView) view.findViewById(R.id.gridView1);
        customGridAdapter =newCustomGridViewAdapter
        (view.getContext(),R.layout.row_grid,gridArray);

        gridView.setAdapter(customGridAdapter);

        return view;
     }

尝试显示gridview的所有数据时遇到问题。只有前三个项目连续显示才会中途切断。对不起，我无法发布图片，因为我只是代表1。我尝试过滚动视图并使滚动条出现，但它不会滚动或显示所有数据

Answer 1

如果要查看设置layout_height = fill_parent所需的所有行不是layout_width = fill_parent和layout_height = wrap_content。它不会能够显示所有行，除非你让它们都很小无论如何，取决于您拥有的细胞数量。如果你有很多细胞那么即使试图让它们出现在一个屏幕上也毫无意义。

我的建议是去列表视图。

Answer 2

我认为您担心显示的行数和列数。如果是，则可以使用numColumns属性设置列数，而行数取决于数据量和列数。 see this for a better insight

GridView没有显示所有数据
