Android实现搜索,EditText+ListView(超简单)

网上有很多实现搜索框的解决方案,我写的这个原理也很简单,对搜索框进行监听,然后利用adapter.notifyDataSetChanged()对listview进行实时刷新.

下图是我想达到的效果

首先我们先构造ListView

private ListView listView;
    private List<Map<String,Object>> personalList =new ArrayList<Map<String, Object>>();
    private List<Map<String, Object>> listItems = new ArrayList<Map<String, Object>>();
    private EditText editText;
    private SimpleAdapter adapter;

@Override
    public void InitView() {
      
        List<ShopClient> shopClient = DataSupport.findAll(ShopClient.class);
    
        for (ShopClient shopClient1 : shopClient) {
            Map<String,Object> map=new HashMap<String,Object>();
            map.put("name",shopClient1.getClient_name());
            map.put("number",shopClient1.getClient_phone());
            personalList.add(map);
        }
    }
    
    @Override
    public void InitData() {
         adapter = new SimpleAdapter(getActivity(),personalList,R.layout.list_call_client,
                new String[]{
      "name","number"},new int[]{R.id.Text_client_name,R.id.Text_client_number});
        listView = (ListView)this.getView().findViewById(R.id.newhome_listview_client);
        listView.setAdapter(adapter);
    
    }

现在达到了显示的效果,接下来就是对搜索框的一个监听

editText.addTextChangedListener(new TextWatcher() {
        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            // TODO Auto-generated method stub String name = s.toString();
            changeClient(name);
    
        }
    
        @Override
        public void beforeTextChanged(CharSequence s, int start, int count,
                                      int after) {
            // TODO Auto-generated method stub }
    
        @Override
        public void afterTextChanged(Editable s) {
            // TODO Auto-generated method stub }
    });

看一下  changeClient() 方法:

public void changeClient(String name){
        listItems.clear();
        List<ShopClient> shopClient = DataSupport.where("client_name like ?", "%" + name + "%").find(ShopClient.class);
        for (ShopClient shopClient1 : shopClient) {
            Map<String, Object> map = new HashMap<String, Object>();
            map.put("name", shopClient1.getClient_name());
            map.put("number", shopClient1.getClient_phone());
            listItems.add(map);
        }
        personalList.clear();
        personalList.addAll(listItems);
        adapter.notifyDataSetChanged();
    }
