1、主布局文件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="#F5F5F5"
    android:orientation="vertical" >

    <ListView
        android:id="@+id/lv_apply_classify"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:cacheColorHint="#00000000"
        android:dividerHeight="10dip"
         >
    </ListView>

</LinearLayout>

2、listview 对应的item

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/tv_apply_classify_name"
        android:layout_width="match_parent"
        android:layout_height="35dip"
        android:layout_marginLeft="10dip"
        android:layout_marginRight="10dip"
        android:gravity="center_vertical"
        android:singleLine="true"
        android:text="应用"
        android:textSize="@dimen/font_body_16"
        android:textColor="@color/black" />

    <com.example.view.ClassifyGridView
        android:id="@+id/gv_toolbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginLeft="5dip"
        android:layout_marginRight="5dip"
        android:layout_marginTop="5dp"
        android:horizontalSpacing="1dip"
        android:numColumns="2"
        android:verticalSpacing="1dip" >
    </com.<span style="font-family: Arial, Helvetica, sans-serif;">exaple</span><span style="font-family: Arial, Helvetica, sans-serif;">.ClassifyGridView></span>

</LinearLayout>
3、gridview对应的item

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/lv_item_selector"
    android:orientation="vertical"
    android:padding="5dip" >

    <TextView
        android:id="@+id/tv_apply_name"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="center_horizontal"
        android:layout_marginTop="5dip"
        android:singleLine="true"
        android:text="应用"
        android:textSize="@dimen/font_body_16"
        android:textColor="@color/black" />

    <TextView
        android:id="@+id/tv_description_name"
        android:layout_width="120dip"
        android:layout_height="match_parent"
        android:layout_gravity="center_horizontal"
        android:layout_marginTop="5dip"
        android:maxLines="2"
         android:textSize="@dimen/font_body_14"
        android:text="应用 描述"
        android:textColor="@color/gray" />
 

</LinearLayout>
4、主Activity

public class ClassifyActivity extends Activity {

	private ListView mListView;
	private ClassifyListViewAdapter mListViewAdapter;
	private List<ApplyTest> mArrayList;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.apply_main_classify);
		init();
	}

	private void init() {
		mListView = (ListView) findViewById(R.id.lv_apply_classify);
		initData();
		mListViewAdapter = new ClassifyListViewAdapter(mArrayList,
				ClassifyActivity.this);
		mListView.setAdapter(mListViewAdapter);
	}

	private void initData() {
		mArrayList = new ArrayList<ApplyTest>();
		 
		for (int i = 0; i < 2; i++) {
			ApplyTest testApplyTest = new ApplyTest();
			testApplyTest.setName("测试分类"+i);
			List<ApplySub> arrayListForEveryGridView = new ArrayList<ApplySub>();
			for (int j = 0; j < 4; j++) {
				ApplySub sub = new ApplySub();
				sub.setName("子项"+i+j);
				arrayListForEveryGridView.add(sub);
			}
			testApplyTest.setSubs(arrayListForEveryGridView);
			mArrayList.add(testApplyTest);
		}

	}

	public class ApplyTest {
		private String name;
		private List<ApplySub> subs;

		public String getName() {
			return name;
		}

		public void setName(String name) {
			this.name = name;
		}

		public List<ApplySub> getSubs() {
			return subs;
		}

		public void setSubs(List<ApplySub> subs) {
			this.subs = subs;
		}

	}

	public class ApplySub {
		private String id;
		private String name;

		public String getId() {
			return id;
		}

		public void setId(String id) {
			this.id = id;
		}

		public String getName() {
			return name;
		}

		public void setName(String name) {
			this.name = name;
		}

	}
}

5、listview适配器

public class ClassifyListViewAdapter extends BaseAdapter {
	private List<ApplyTest> mList;
	private Context mContext;

	public ClassifyListViewAdapter(List<ApplyTest> mList,
			Context mContext) {
		super();
		this.mList = mList;
		this.mContext = mContext;
	}

	@Override
	public int getCount() {
		if (mList == null) {
			return 0;
		} else {
			return this.mList.size();
		}
	}

	@Override
	public Object getItem(int position) {
		if (mList == null) {
			return null;
		} else {
			return this.mList.get(position);
		}
	}

	@Override
	public long getItemId(int position) {
		return position;
	}

	@Override
	public View getView(int position, View convertView, ViewGroup parent) {
		ViewHolder holder = null;
		if (convertView == null) {
			holder = new ViewHolder();
			convertView = LayoutInflater.from(this.mContext).inflate(R.layout.apply_main_classify_gv, null);
			holder.gridView = (GridView) convertView.findViewById(R.id.gv_toolbar);
			holder.tv_apply_classify_name = (TextView) convertView.findViewById(R.id.tv_apply_classify_name);
			convertView.setTag(holder);
		} else {
			holder = (ViewHolder) convertView.getTag();
		}

		if (this.mList != null) {
			if (holder.gridView != null) {
				ApplyTest mApplyTest = this.mList.get(position);
				ClassifyGridViewAdapter gridViewAdapter = new ClassifyGridViewAdapter(mContext,mApplyTest.getSubs());
				holder.gridView.setAdapter(gridViewAdapter);
				holder.tv_apply_classify_name.setText("分类"+position+mApplyTest.getName());
			}
		}
		return convertView;
	}

	private class ViewHolder {
		GridView gridView;
		public TextView tv_apply_classify_name;
	}
}

6、gridview 适配器

public class ClassifyGridViewAdapter extends BaseAdapter {
	private Context mContext;
	private List<ApplySub> mList;

	public ClassifyGridViewAdapter(Context mContext,
			List<ApplySub> mList) {
		super();
		this.mContext = mContext;
		this.mList = mList;
	}

	@Override
	public int getCount() {
		if (mList == null) {
			return 0;
		} else {
			return this.mList.size();
		}
	}

	@Override
	public Object getItem(int position) {
		if (mList == null) {
			return null;
		} else {
			return this.mList.get(position);
		}
	}

	@Override
	public long getItemId(int position) {
		return position;
	}

	@Override
	public View getView(final int position, View convertView, ViewGroup parent) {
		ViewHolder holder = null;
		if (convertView == null) {
			holder = new ViewHolder();
			convertView = LayoutInflater.from(this.mContext).inflate(R.layout.apply_main_classify_group, null);
			holder.tv_apply_name = (TextView) convertView.findViewById(R.id.tv_apply_name);
			holder.tv_description_name = (TextView) convertView.findViewById(R.id.tv_description_name);
			holder.iv_apply_classify_icon =  (RemoteImageView) convertView.findViewById(R.id.iv_apply_classify_icon);
			convertView.setTag(holder);
		} else {
			holder = (ViewHolder) convertView.getTag();
		}

		if (this.mList != null) {
			ApplySub sApplySub = this.mList.get(position);
			if (holder.tv_apply_name != null) {
				holder.tv_apply_name.setText(sApplySub.getName());
//				holder.tv_description_name.setText(hashMap.get("content").toString());
				holder.tv_apply_name.setOnClickListener(new OnClickListener() {
					@Override
					public void onClick(View v) {
						Toast.makeText(mContext, "第" + (position + 1) + "个",
								Toast.LENGTH_SHORT).show();
					}
				});
			}
		}
		return convertView;
	}

	private class ViewHolder {
		TextView tv_apply_name;
		TextView tv_description_name;
	}
}

7、重写gridview让其不滚动

public class ClassifyGridView extends GridView {
	
	public ClassifyGridView(android.content.Context context,android.util.AttributeSet attrs) {
		super(context, attrs);
	}

	/**
	 * 设置不滚动
	 */
	public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
		int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,
				MeasureSpec.AT_MOST);
		super.onMeasure(widthMeasureSpec, expandSpec);

	}

}
