朋友你好我有项目点击听众问题上的ListView Android中...我的code告诉我项目的正确位置，但不正确的名称我需要帮助...即时通讯在Android的新...

下面是我的code

 公共无效的ListView（）{            ListView控件=（ListView控件）findViewById（R.id.list_View）;            最终的String [] [] =预测{{Food.NewDishInfo.DISH_CALORIE，Food.NewDishInfo.DISH_FAT}};            最后弦乐选择= Food.NewDishInfo.DISH_NAME +怎么样？            的String [] = selection_args新的String [] {dish_name};            最后ArrayAdapter＆LT;串GT;适配器=新ArrayAdapter＆LT;串GT;（这一点，R.layout.row_layout，selection_args）;            listView.setAdapter（适配器）;            listView.setOnItemClickListener（            新AdapterView.OnItemClickListener（）{                @覆盖                    公共无效onItemClick（适配器视图＆LT;＆GT;适配器视图，视图观点，INT I，长L）{                    字符串selection_args =您选择了+                            将String.valueOf（adapterView.getItemAtPosition（I））;                    Toast.makeText（DataListActivity.this，位置：+ I + selection_args，Toast.LENGTH_LONG）.show（）;                }            }）;        } 

这是我的名单适配器code .....

解决方案

使用code

  listView.setOnItemClickListener（新AdapterView.OnItemClickListener（）{        @覆盖        公共无效onItemClick（适配器视图＆LT;＆GT;母公司，观景，                                INT位置，长的id）{            Toast.makeText（getApplicationContext（），                    这道菜的名字是：+ dataprovider.getName（），Toast.LENGTH_SHORT）.show（）; 

可能会有所帮助。

Hello friends I have problem in item click listener on ListView in android... My code tells me right position of item but not right name I need help... Im new in android...

Here is my code

public void listView(){

            listView = (ListView)findViewById(R.id.list_View);
            final String[][] projections = {{Food.NewDishInfo.DISH_CALORIE, Food.NewDishInfo.DISH_FAT}};
            final String selection = Food.NewDishInfo.DISH_NAME+" LIKE ?";
            String[] selection_args = new String[]{"dish_name"};
            final ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,R.layout.row_layout,selection_args);
            listView.setAdapter(adapter);
            listView.setOnItemClickListener(
            new AdapterView.OnItemClickListener(){
                @Override
                    public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {

                    String selection_args = "You selected " +
                            String.valueOf(adapterView.getItemAtPosition(i));

                    Toast.makeText(DataListActivity.this,"position : " + i +selection_args, Toast.LENGTH_LONG).show();

                }
            });
        }

This is my list adapter code.....

public class ListDataAdapter extends ArrayAdapter {
    List list = new ArrayList();
    public ListDataAdapter(Context context, int resource) {

        super(context, resource);
    }
    static class LayoutHandler{
        TextView name,calorie,fat;
    }

    @Override
    public void add(Object object) {
        super.add(object);
        list.add(object);

    }

    @Override
    public int getCount() {
        return list.size();
    }

    @Override
    public Object getItem(int position) {
        return list.get(position);
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View row = convertView;
        LayoutHandler layoutHandler;
        if (row == null)
        {
            LayoutInflater layoutInflater = (LayoutInflater)this.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            row = layoutInflater.inflate(R.layout.row_layout,parent,false);
            layoutHandler = new LayoutHandler();
            layoutHandler.name = (TextView)row.findViewById(R.id.text_dish_name);
            layoutHandler.calorie = (TextView)row.findViewById(R.id.text_dish_calorie);
            layoutHandler.fat = (TextView)row.findViewById(R.id.text_dish_fat);
            row.setTag(layoutHandler);
        }
        else
        {
            layoutHandler = (LayoutHandler) row.getTag();

        }
        DataProvider dataProvider = (DataProvider)this.getItem(position);
        layoutHandler.name.setText(dataProvider.getName());
        layoutHandler.calorie.setText(dataProvider.getCalorie());
        layoutHandler.fat.setText(dataProvider.getFat());


        return row;
    }
}
