Wenn ich auf Schaltfläche Textview in Listview, geändert letzte Zeile oder eine andere Zeile Textview ändern

Question

ich habe costum Listview wie folgt aus:

Row1 Button1(-) TextView Button2(+)

Row2 Button1(-) TextView Button2(+)

Row3 Button1(-) TextView Button2(+)

Row4 Button1(-) TextView Button2(+)

Row5 Button1(-) TextView Button2(+)

Wenn ich versuche setOnClickListener in getView für jede Button, änderte eine andere Zeile TextView.

i Row Klicken 2/Button2(+), so TextView Must ++ (1 bis 2) oder Klicken Sie auf Zeile 2/Button1(-), TextView Must -- (2: 1) Aber TextView in Reihe geändert 5--- oder ++.

Dies ist mein Adapter

public class adap_Mive extends BaseAdapter { 

Context contextt; 

private LayoutInflater myInflater; 
public List<dm_Mive> list; 

public adap_Mive(Context context) { 
    myInflater = LayoutInflater.from(context); 
    contextt = context; 
} 

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

@Override 
public Object getItem(int position) { 
    return null; 
} 

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

public void setData(List<dm_Mive> list) { 
    this.list = list; 
} 

public void clearData() { 
    // clear the data 
    list.clear(); 
} 

Holder holder = null; 

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

    if (convertView == null) {

    String Image_Name = null; 

    String pic[] = profpic.split("/");

    File picDir = new File(extStore, "Froot"); 
    File file = new File(picDir, Image_Name); 

    String ProfPic = file.toString();
