Solving ah: ListView selected item to change the background color, the next roll that have been changed

For example, ListView on my phone screen can display a total of 15 lines, if I select the first line, then the background color of the first line is changed, but the first 16 rows have been changed, solving ah, I change the background code as follows:
private View oldLinearLayout;
listView.setOnItemClickListener (new AdapterView.OnItemClickListener () {
@ Override
public void onItemClick (AdapterView paramAdapterView,
View paramView, int paramInt, long paramLong) {

if (beforeLinearLayout! = null) {
oldLinearLayout.setBackgroundDrawable (null);
}

paramView.setBackgroundColor (Color.GREEN);
oldLinearLayout = paramView;
}
});

Probably thinking:

1. Saved choose the current selection, then notify adapter to refresh the view

2 and then to fill the current View
based on the current selection in getView

 
/ / Adapter in 
public void setSelected (int selected) {
this.selected = selected; 
notifyDataSetChanged (); 
} 


/ / 
 When OnItemClickadapter.setSelected (position);

this.selected what this is, ah, ah, I did not inherit Adapter, nor setSelected this method ah
This is what I wrote:
SimpleAdapter listItemAdapter = new SimpleAdapter (this, listdata, R.layout.list_salesck,
new String [] {"billdate", "state", "zhaiyao", "billname", "userfullname"},
new int [] {R.id.billdate, R.id.textView14, R.id.zhaiyao, R.id.billtype, R.id.userfullname});

listView.setAdapter (listItemAdapter);
listView.setOnItemClickListener (new AdapterView.OnItemClickListener () {
public void onItemClick (AdapterView paramAdapterView,
View paramView, int paramInt, long paramLong) {
if (oldLinearLayout! = null) {
oldLinearLayout.setBackgroundDrawable (null);
}
/ / Set the background color of a member of the Grey
paramView.setBackgroundColor (Color.GRAY);
nowClick = paramInt;
oldLinearLayout = paramView;
}
});

How I should add, ah, beg specific code

1 Use ViewHolder mode initialization function is to avoid duplication of View, of course, a more appropriate approach is to do if the currently selected
within ViewHolder
Judgment, do background replacement,

2. LZ for Adapter adapter class is not very understanding, it is recommended to go to first understand BaseAdapter under this category, the above code in the adapter,

BaseAdapter is a specific instance of a subclass of the class, you should go to achieve this Adapter instance of the class, as a data source to provide data to the layout

I posted some of my code you can refer to solve this problem

 
import java.util.List; 

import android.content.Context; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.BaseAdapter; 
import android.widget.ImageView; 
import android.widget.TextView; 

import com.ishow.funnymap.bean.Menu; 
import com.ishow.funnymap.ui.R; 

public class MenuGridViewAdapter extends BaseAdapter {

private Context context; 
private List  menuGridViewList; 
private int selected; 

public MenuGridViewAdapter (Context context, List  menuGridViewList) {
this.context = context; 
this.menuGridViewList = menuGridViewList; 
} 

/ / Set the current selection state 
public void setSelected (int selected) {
this.selected = selected; 
notifyDataSetChanged (); 
} 

@ Override 
public int getCount () {
return menuGridViewList.size (); 
} 

@ Override 
public Object getItem (int position) {
return menuGridViewList.get (position); 
} 

@ Override 
public long getItemId (int position) {
return 0; 
} 

@ Override 
public View getView (int position, View convertView, ViewGroup parent) {

ViewHolder viewHolder = null; 
if (convertView == null) {
convertView = inflateView (); 
} 
viewHolder = (ViewHolder) convertView.getTag (); 
viewHolder.init (convertView); 
viewHolder.fillFromItem (position, selected == position); 
return convertView; 
} 

private View inflateView () {
LayoutInflater inflater = (LayoutInflater) context 
. GetSystemService (Context.LAYOUT_INFLATER_SERVICE); 
View view = inflater.inflate (R.layout.switch_pull_down_menu_item, null); 
view.setTag (new ViewHolder ()); 
return view; 
} 

class ViewHolder {
ImageView imageView; 
TextView textView; 

public void init (View view) {
imageView = (ImageView) view.findViewById (R.id.menu_ico); 
textView = (TextView) view.findViewById (R.id.menu_description); 
} 

public void fillFromItem (int position, boolean isCurrent) {
if (isCurrent) {
imageView.setBackgroundResource (menuGridViewList.get (position) 
. GetImageResNormal ()); 
} Else {
imageView.setBackgroundResource (menuGridViewList.get (position) 
. GetImageResPressed ()); 
} 
textView.setText (menuGridViewList.get (position) getTextName ().); 
} 

} 
} 

OnItemClick Event

 
menuGridView.setOnItemClickListener (new OnItemClickListener () {

@ Override 
public void onItemClick (AdapterView  parent, View view, 
int position, long id) {
onMenuSelectedListener.onMenuSelected (menuGridViewAdapter 
. GetItem (position)); 
menuGridViewAdapter.setSelected (position); 
/ / Dismiss (); 
} 
});
