Android-------ListView列表中擷取EditText輸入的值

標籤：main   fill   listener   create   擷取   app   start   技術分享   text   

最近項目的購物車中用列表中包含了留言功能, 需要擷取EditText輸入的內容，當購買多件商品時，就有點棘手了。

經過查資料解決了這個功能，並寫了一個案例；

   ：

    

 可以在商品資料用一個欄位來管理留言資料，這樣就可以方便的操作了。

 代碼：

 

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) {        }    }}
