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) {
}
}
}
