Question

我通过url从服务器数据库获取所有的manunames我使用base adapter将所有menunames附加到editext自定义listview中。现在我将Edittext更改的值转换为列表数组。现在我想要存储edittext所有值，无论他是否更改了menunames.Eg：x，yz ...来自数据库的menunames附加到editext现在我将menuname更改为b并且在editext.now中我想要[x，bc ..]在arraylist中的vaules，但现在我得到了b，c

          this is my code
            public View getView(int position, View convertView, ViewGroup parent) {
    ViewHolder holder;


    if (convertView == null) {
        holder = new ViewHolder();
        convertView = inflater.inflate(R.layout.editmainmenulist, null);
        holder.caption = (EditText) convertView
                .findViewById(R.id.editmaimenu);
        holder.caption1=(ImageView) convertView.findViewById(R.id.menuimage);
        convertView.setTag(holder);
    } else {
        holder = (ViewHolder) convertView.getTag();
    }
    //Fill EditText with the value you have in data source
    holder.caption.setText(itemnames[position]);//here only i append database menunames
    holder.caption.setId(position);
    holder.caption1.setImageBitmap(bmps[position]);

    //we need to update adapter once we finish with editing
    holder.caption.setOnFocusChangeListener(new OnFocusChangeListener() {
        public void onFocusChange(View v, boolean hasFocus) {
            if (!hasFocus){
                final int position = v.getId();
                final EditText Caption = (EditText) v;
                itemnames[position] = Caption.getText().toString();

                arr.add(Caption.getText().toString());//here only i think problem..please see any body can tell what i have mistake has been done


            }
        }    
    });     

    return convertView;
}
      }

           class ViewHolder {
EditText caption;
ImageView caption1;
      }

    class ListItem {
String caption;
     }

我想知道editext值是否发生变化的所有edittext值。为了更新purpous。我以前可以买到所有的名字。我希望将旧的游戏名称更新为新的游戏名称

将TextChangedListener添加到EditText

中的getView()

<强>代码：

holder.caption.addTextChangedListener(new TextWatcher()
{           
  @Override
   public void onTextChanged(CharSequence s, int start, int before, int count)
    {
     // TODO Auto-generated method stub         
    }           
    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after)
    {
     // TODO Auto-generated method stub
     }
    @Override
    public void afterTextChanged(Editable s)
    {
    // TODO Auto-generated method stub
    String data =  holder.caption.getText().toString().trim();
    }
});

现在可以根据需要从edittext获取数据，onTextChanged，beforeTextChanged或afterTextChanged ..
