android actionbar searchview搜索提示

使用listview作为搜索提示显示容器,这里需要几个东西

1：searchview文字改变事件时后台查询然后填充到listview并显示出来

[java]  view plain  copy

1. MenuItem searchItem = menu.findItem(R.id.action_search);    
2.         SearchView searchView = (SearchView) searchItem.getActionView();      
3.           
4.         searchView.setOnQueryTextListener(new OnQueryTextListener () //搜索时会触发这个事件搜索即可  
5.         {  
6.   
7.             public boolean onQueryTextSubmit(String query) {  
8.                 // TODO Auto-generated method stub  
9.                 return false;  
10.             }  
11.   
12.             public boolean onQueryTextChange(String newText) {  
13.                 if(newText!="")  
14.                  {  
15.                     listView.setVisibility(0);  
16.                     Object[] names = new Object[]{newText,"cz0","aj","xd","jl","mm"};  
17.                     listView.setAdapter(new ArrayAdapter<Object>(getActivity().getApplicationContext(),  
18.                             android.R.layout.simple_expandable_list_item_1, names));                   
19.                  }  
20.                 return false;  
21.             }     
22.         });  

2:当listview触摸时隐藏掉输入键盘,不然控件会很少

[java]  view plain  copy

1. listView.setOnTouchListener(new OnTouchListener(){  
2.             public boolean onTouch(View v, MotionEvent event) {  
3.                 // TODO Auto-generated method stub  
4.                   
5.                 ((InputMethodManager)getActivity().getSystemService(Context.INPUT_METHOD_SERVICE)).  
6.                 hideSoftInputFromWindow(getActivity().getCurrentFocus().getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);  
7.                 return false;  
8.             }  
9.         });  

3:当searchview搜索完毕时隐藏掉listview

[java]  view plain  copy

1. searchItem.setOnActionExpandListener(new android.view.MenuItem.OnActionExpandListener() {  
2.   
3.             public boolean onMenuItemActionExpand(MenuItem item) {  
4.                 // TODO Auto-generated method stub  
5.                 return true;  
6.             }  
7.   
8.             public boolean onMenuItemActionCollapse(MenuItem item) {  
9.                 // TODO Auto-generated method stub  
10.                 listView.setVisibility(8);  
11.                 return true;  
12.             }              
13.         });
