[哎，真难]

autotext看看呗

[展翼翔宇]

是做页面的搜索内容吗

http://www.trinea.cn/android/android-searchview-and-search-tips-impl/ 搜索可以参考下这个。

问题已解决，核心

引用 3 楼 u012740751 的回复:

mEdtSearch.addTextChangedListener(new TextWatcher() { @Override public void onTextChanged(CharSequence s, int start, int before, int count) { filterData(s.toString()); } @Override public void beforeTextChanged(CharSequence s, int start, int count, int after) { } @Override public void afterTextChanged(Editable s) { } }); private void filterData(String filterStr) { List<House> changeDatas = new ArrayList<House>(); if (TextUtils.isEmpty(filterStr)) { changeDatas = mList; } else { changeDatas.clear(); for (House house : mList) { String name = house.getName(); String address = house.getAddressStreet(); if (name.indexOf(filterStr.toString()) != -1 || address.indexOf(filterStr.toString()) != -1) { changeDatas.add(house); } } } mAdapterHouse.updata(changeDatas); } 给你个例子。。。大概就死这样。。。根据搜索的内容，在你的list中找出相应的显示出来

谢谢，你的这个很有参考意义；我的实现方法更简单，用的是内部类； 代码如下，供后来者参考

			public void onTextChanged(CharSequence c, int start, int before, int count){
				//在适配器是用内部方法getfilter()筛选数据
				if (c != null && (c.toString()).trim().length() != 0&&adapter!=null){
				adapter.getFilter().filter(c);
				adapter.notifyDataSetChanged();
				}
				
			}
			public void beforeTextChanged(CharSequence c, int start, int before, int count){
				 // TODO Auto-generated method stub
	               //这是文本框改变之前会执行的动作
			}
			public void afterTextChanged(Editable c){
				 // TODO Auto-generated method stub
	               /**这是文本框改变之后 会执行的动作
	                 * 因为我们要做的就是，在文本框改变的同时，我们的listview的数据也进行相应的变动，并且如一的显示在界面上。
	                 * 所以这里我们就需要加上数据的修改的动作了。
	                 */
	               if(c.length() == 0){
	            	   mServers=ServerLab.get(getActivity()).getServers();
	  				 adapter=new ServerInfoAdapter(mServers);
	  				 mListView.setAdapter(adapter);
	                     ivDeleteText.setVisibility(View.GONE);//当文本框为空时，则叉叉消失
	               }
	               else {
	                     ivDeleteText.setVisibility(View.VISIBLE);//当文本框不为空时，出现叉叉
	                    // myhandler.post(eChanged);
	               }			
			}
		});

我这边有个后台管理系统要做页面，也是有搜索功能，支持模糊搜索，然后是点击搜索按钮会出现后台所有游戏，每个游戏都能点击进入到数据展现的页面，应该怎么做
