Android 搜索功能

以下是截图

下面是部分代码：

et_search.addTextChangedListener(new TextWatcher(){

			@Override
			public void beforeTextChanged(CharSequence paramCharSequence,
					int paramInt1, int paramInt2, int paramInt3) {
				// TODO Auto-generated method stub
				Log.d(TAG, "beforeTextChanged");
			}

			@Override
			public void onTextChanged(CharSequence value,
					int paramInt1, int paramInt2, int paramInt3) {
				// TODO Auto-generated method stub
				Log.d(TAG, "onTextChanged");
				Log.w(TAG, "input.text=" + value.toString());
				Message msg = new Message();
				msg.what = MSG_KEY;
				Bundle data = new Bundle();
				data.putString("value", value.toString());
				msg.setData(data);
				handler.sendMessage(msg);			
				
			}

			@Override
			public void afterTextChanged(Editable paramEditable) {
				// TODO Auto-generated method stub
				Log.d(TAG, "afterTextChanged");
			}
			
		});
		SimpleAdapter simpleAdapter = new SimpleAdapter(MainActivity.this, listItems, R.layout.simple_item, new String[]{"image","weather","desc"}, new int[]{R.id.image,R.id.weather,R.id.desc});
		
		listView.setAdapter(simpleAdapter);
		
		handler = new Handler() {
			@Override
			public void handleMessage(Message msg) {
				switch (msg.what) {
				case MSG_KEY:
					refreshListView(msg.getData().get("value").toString());
				}
			}

			//刷新ListView
			private void refreshListView(String value) {
				if (value == null || value.trim().length() == 0){
					//把listItems集合中的名字和布局中的相关信息一一对应
					SimpleAdapter simpleAdapter = new SimpleAdapter(MainActivity.this, listItems, R.layout.simple_item, new String[]{"image","weather","desc"}, new int[]{R.id.image,R.id.weather,R.id.desc});
					
					listView.setAdapter(simpleAdapter);
				}

				
				final List<HashMap<String,Object>> tmplistItems = new ArrayList<HashMap<String,Object>>();
				
				for(int i=0;i<names.length;i++){
					HashMap<String,Object> tmplistItem = new HashMap<String,Object>();
					if(names[i].indexOf(value)>=0){
						tmplistItem.put("image", imageIDs[i]);
						tmplistItem.put("weather", names[i]);
						tmplistItem.put("desc", desc[i]);
						tmplistItems.add(tmplistItem);
					}
				}
					
				SimpleAdapter simpleAdapter = new SimpleAdapter(MainActivity.this, tmplistItems, R.layout.simple_item, new String[]{"image","weather","desc"}, new int[]{R.id.image,R.id.weather,R.id.desc});
				
				listView.setAdapter(simpleAdapter);
				listView.invalidateViews();
			}
				
		};
