listview在搜索后受到干扰。 （数据显示在底部）

Question

搜索后从本地数据库获取数据。我得到了这个观点。

try{                
            DatabaseHandler db=new DatabaseHandler(getApplicationContext());
            retailers=new ArrayList<HashMap<String, String>>();             
            String str=str_search[0];
            retailers=db.getRetailers(str);

        }catch(Exception e){
            Log.d("Exception",e.toString());
        }          

        // Keys used in Hashmap 
        String[] from = {"id","shop_name","address"};

        // Ids of views in listview_layout
        int[] to = {R.id.id,R.id.shopname,R.id.address};

        // Instantiating an adapter to store each items
        // R.layout.listview_layout defines the layout of each item         

        ListAdapter adapter = new SimpleAdapter(RetailersListActivity.this,retailers, R.layout.retailer_list_item, from, to);  

        return adapter;

这个问题与listview或某些coading问题有关

plz help !!!

我认为在您的xml文件中，您将ListView设置在底部布局上方，因此请尝试按照以下方式设置xml布局：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    //here your search layout should be android:layout_alignParentTop="true"

     <ListView
            android:id="@+id/attendanceList"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_below="@+id/your_search_layout"
            android:layout_above="@+id/your_bottom_layout" >
     </ListView>

    //here your bottom layout should be android:layout_alignParentBottom="true"

</RelativeLayout>

希望这种情况可以帮助你...
