listview嵌套gridview,最主要应该解决的问题是listview跟GridView的滑动问题.这个利用GridView是自定义的,就是让GridView内容有多大就显示多大,然后禁用他的滑动,这样就不会跟listview的滑动冲突了.

public class MyGridView extends GridView  {      public MyGridView(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);        }    }

listview嵌套gridview,会想到这个的人,对他们怎样布局应该很清楚了.最外是listview,listview的每个item是gridview,gridview的每个item再是其他布局(这里不上代码).

主类代码,我这里的listview是给定的多少个,对listview熟悉的人应该知道怎么动态添加listview,这里为了方便就偷下懒哈.gridview也是一样,给定九个子item.

public class MainActivity extends Activity {		private ListView mListView;	private MyAdapter myAdapter;		@Override	protected void onCreate(Bundle savedInstanceState) {		super.onCreate(savedInstanceState);		setContentView(R.layout.activity_main);				mListView = (ListView)this.findViewById(R.id.listView);		myAdapter = new MyAdapter(this);		mListView.setAdapter(myAdapter);	}		class MyAdapter extends BaseAdapter{				private Context context;		private LayoutInflater inflater;				private GridView gridView;		private ImageView imageView;		private int[] imgId = new int[]{R.drawable.ic_launcher				,R.drawable.ic_launcher,R.drawable.ic_launcher,				R.drawable.ic_launcher,R.drawable.ic_launcher,				R.drawable.ic_launcher,R.drawable.ic_launcher,				R.drawable.ic_launcher,R.drawable.ic_launcher};				MyAdapter(Context context){			this.context = context;		}		@Override		public int getCount() {			// TODO Auto-generated method stub			return 20;		}		@Override		public Object getItem(int arg0) {			// TODO Auto-generated method stub			return null;		}		@Override		public long getItemId(int arg0) {			// TODO Auto-generated method stub			return 0;		}		@Override		public View getView(int arg0, View view, ViewGroup arg2) {			// TODO Auto-generated method stub			view = inflater.from(context).inflate(R.layout.test, null);			gridView = (GridView)view.findViewById(R.id.gridview);						List
     
      > listItems = new ArrayList
      
       
        >();						for(int i = 0;i
        
          map = new HashMap
         
          (); map.put("img", imgId[i]); listItems.add(map); } SimpleAdapter simpleAdapter = new SimpleAdapter(context, listItems, R.layout.image, new String[]{"img"}, new int[]{R.id.img}); gridView.setAdapter(simpleAdapter); return view; } } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.main, menu); return true; }}

这只是个listview嵌套gridview的基础.大家可以在这个基础上作出很多好看的界面,或者功能来的.
