抽屉样式作为一种比较常用的View，有很多实现方式。

这里是一种简单的实现方式：

第一步：布局文件

第二部：MainActivity

public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);                Intent intent = new Intent(Intent.ACTION_MAIN, null);        intent.addCategory(Intent.CATEGORY_LAUNCHER);        apps = getPackageManager().queryIntentActivities(intent, 0);                gv = (GridView) findViewById(R.id.allApps);        sd = (SlidingDrawer) findViewById(R.id.sliding);        iv = (ImageView) findViewById(R.id.imageViewIcon);                gv.setAdapter(new GridAdapter());                sd.setOnDrawerOpenListener(new SlidingDrawer.OnDrawerOpenListener(){
   // 开抽屉            @Override            public void onDrawerOpened() {                iv.setImageResource(R.drawable.ic_launcher);            }        });                sd.setOnDrawerCloseListener(new SlidingDrawer.OnDrawerCloseListener() {            @Override            public void onDrawerClosed() {                iv.setImageResource(R.drawable.ic_launcher);// 响应关抽屉事件            }        });    }    //适配器    public class GridAdapter extends BaseAdapter {        public GridAdapter() {        }        public int getCount() {            // TODO Auto-generated method stub            return apps.size();        }        public Object getItem(int position) {            // TODO Auto-generated method stub            return apps.get(position);        }        public long getItemId(int position) {            // TODO Auto-generated method stub            return position;        }        @Override        public View getView(int position, View convertView, ViewGroup parent) {            // TODO Auto-generated method stub            ImageView imageView = null;                        if (convertView == null) {                imageView = new ImageView(MainActivity.this);                imageView.setScaleType(ImageView.ScaleType.FIT_CENTER);                imageView.setLayoutParams(new GridView.LayoutParams(50, 50));            } else {                imageView = (ImageView) convertView;            }            ResolveInfo ri = apps.get(position);            imageView.setImageDrawable(ri.activityInfo.loadIcon(getPackageManager()));            return imageView;        }    }
