我搜索了一个类似的问题在这里计算器和我没有找到一个解决方案，plase，有人帮我

继承人playerAdapter.java

public class playerAdapter extends ArrayAdapter<Player>{ 
private ArrayList<Player> entries; 
private Activity activity; 

public playerAdapter(Activity a, int textViewResourceId, ArrayList<Player> entries) { 
    super(a, textViewResourceId, entries); 
    this.entries = entries; 
    this.activity = a; 
} 

public static class ViewHolder{ 
    public TextView item1; 
    public TextView item2; 
} 

@Override 
public View getView(int position, View convertView, ViewGroup parent) { 
    View v = convertView; 
    ViewHolder holder; 
    if (v == null) { 
     LayoutInflater vi = 
      (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     v = vi.inflate(R.layout.itemplayer, null); 
     holder = new ViewHolder(); 
     holder.item1 = (TextView) v.findViewById(R.id.nomecharlist); 
     //holder.item2 = (TextView) v.findViewById(R.id.small); 
     v.setTag(holder); 
    } 
    else 
     holder=(ViewHolder)v.getTag(); 

    final Player custom = entries.get(position); 
    if (custom != null) { 
     holder.item1.setText(custom.getNomePlayer()); 
     //holder.item2.setText(custom.getSecond()); 
    } 
    return v; 
} 

}

我不知道代码的确切问题是什么，但我确实知道这太复杂了。尝试这样的：

@Override 
public View getView(int position, View convertView, ViewGroup parent) { 
    if (convertView == null) { 
     LayoutInflater vi = 
      (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     convertView = vi.inflate(R.layout.itemplayer, null); 
    } 
    final Player custom = entries.get(position); 
    if (custom != null) 
     ((TextView) convertView.findViewById(R.id.nomecharlist)).setText(custom.getNomePlayer()); 
    return convertView; 
}
