核心代码：

// ListView的单击事件
		imgListView.setOnItemClickListener(new OnItemClickListener() {
			public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
					long arg3) {
				// 加载图片预览
				BitmapFactory.Options options = new BitmapFactory.Options();
				options.inSampleSize = 2;
				bitmap = BitmapFactory.decodeFile(pathsList.get(arg2), options);
				preImage.setImageBitmap(bitmap);

				// String msg = "";
				// for (int i = 0; i < isSelected.size(); i++) {
				// if (isSelected.get(i) == true) {
				// msg = msg + pathsList.get(i) + "第" + i + "张" + "\n";
				// }
				// }
				//
				// ShowMsg.showToast(getApplicationContext(), handler, msg);

				/******* 直接点击ListView设置checkbox ********/
				// ViewHolder vHollder = (ViewHolder) arg1.getTag();
				// 在每次获取点击的item时将对于的checkbox状态改变，同时修改map的值。
				// vHollder.checkBox.toggle();// 反转当前视图的选中状态
				// 点击预览
				// String text = "";
				// String select_id = "";
				// if (vHollder.checkBox.isChecked() == true) {
				// isSelect[arg2] = true;
				//
				// } else {
				// isSelect[arg2] = false;
				// }
				//
				// for (int i = 0; i < isSelect.length; i++) {
				// if (isSelect[i]) { // 如果该选项被选中
				// text = text + pathsList.get(i) + "第" + i + "张" + "\n";
				// select_id = select_id + i + ";";
				// Toast.makeText(getApplicationContext(),
				// "选中了：\n" + text, 5000).show();
				// }
				// }
				// hasSelect = select_id;
				// ListPicAdapter.isSelected.put(arg2, vHollder.checkBox
				// .isChecked());

			}

apt-get install yum
./configure -prefix=/usr/local
sudo apt-get --reinstall install ttf-dustin khangman kdeedu kde

ln -s /usr/local/lib/libevent-2.0.so.5 /lib/libevent-2.0.so.5

./memcached -d -m 64 -p 11211 -l 127.0.0.1 -u nobody -c 1024

     memcache 的安装会报没有编译器所以应该首先安装gcc

  gcc的安装方法为 sudo apt-get  install  build-essential

   然后在安装memcache安装之前要先安装libevent

  下载地址为

wget http://www.monkey.org/~provos/libevent-2.0.10-stable.tar.gz

下载后使用wget http://www.monkey.org/~provos/libevent-2.0.13-stable.tar.gz
tar xzvf  libevent-2.0.13-stable.tar.gz
./configure
make
make install安装Memcached

wget http://memcached.googlecode.com/files/memcached-1.4.7.tar.gz
tar xvzf memcached-1.4.7.tar.gz
cd memcached-1.4.7
./configure --prefix=/usr/local/memcached/
make
make install
方式安装即可。
