最近项目的购物车中用列表中包含了留言功能, 需要获取EditText输入的内容，当购买多件商品时，就有点棘手了。

经过查资料解决了这个功能，并写了一个案例；

   效果图：

 可以在商品数据用一个字段来管理留言数据，这样就可以方便的操作了。

 代码：

public class MainActivity extends AppCompatActivity {
ListView listView;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    initView();
}

private void initView(){
    listView=(ListView)findViewById(R.id.listview);
    listView.setAdapter(new ListAdapter(this));
}
public void saveEditData(int position, String str) {
    Toast.makeText(this,str+"----"+position,Toast.LENGTH_LONG).show();
}

}

Adapter

public class ListAdapter extends BaseAdapter {
Context context;
LayoutInflater inflater;
String[] strings=new String[]{"商品1","商品2","商品3"};
public ListAdapter(Context context) {
    this.inflater=LayoutInflater.from(context);
    this.context=context;
}

@Override
public int getCount() {
    return 3;
}

@Override
public Object getItem(int position) {
    return strings[position];
}

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

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    ViewHolder holder;
    if (null == convertView){
        convertView = inflater.inflate(R.layout.item_multiple_confirm,null);
        holder =new ViewHolder(convertView,position);
        convertView.setTag(holder);
    }else {
        holder = (ViewHolder) convertView.getTag();
    }
    holder.tv_name.setText(getItem(position).toString());
    return convertView;
}

class ViewHolder{
    TextView tv_name;
    EditText editText;
    public ViewHolder(View view,int pisition){
        tv_name = (TextView) view.findViewById(R.id.fill_order_name);
        editText= (EditText) view.findViewById(R.id.fill_order_ltext);
        editText.setTag(pisition);//存tag值
        editText.addTextChangedListener(new TextSwitcher(this));
    }
}

class TextSwitcher implements TextWatcher {
    private ViewHolder mHolder;

    public TextSwitcher(ViewHolder mHolder) {
        this.mHolder = mHolder;
    }

    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {

    }

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {
        int position = (int) mHolder.editText.getTag();//取tag值
        ((MainActivity)context).saveEditData(position, s.toString());
    }

    @Override
    public void afterTextChanged(Editable s) {

    }
}

}

代码是写的比较简单
