如何获得所选multichoice列表视图中的数据。我有多个选择列表视图。我要存储在字符串数组列表视图中选择的项目。任何人都可以指导我如何存储在字符串数组列表视图中选择的项目。

  SparseBooleanArray selectedItems = lv.getCheckedItemPositions（）;
INT ID1 = lv.getCheckedItemPosition（）;
Toast.makeText（getApplicationContext（），+ ID1，Toast.LENGTH_SHORT）.show（）;

的for（int i = 0; I＆LT; lv_arr.length;我++）{
    如果（selectedItems.get（i））的{
        的String []的GetString =（字符串）lv.getAdapter（）的getItem（
            selectedItems.keyAt（ⅰ））;
        的System.out.println（+的GetString））;
    }
}
 

解决方案

嘿，我已经使用的字符串保存所有的检查项目从list..See的code如下：

 进口android.app.Activity;
进口android.os.Bundle;
进口android.util.Log;
进口android.util.SparseBooleanArray;
进口android.view.View;
进口android.widget.AdapterView;
进口android.widget.AdapterView.OnItemClickListener;
进口android.widget.ArrayAdapter;
进口android.widget.ListView;



公共类ViewsActivity扩展活动
{

    私人的ListView LVIEW;
    私人字符串lv_items [] = {机器人，iPhone，黑莓，
            AndroidPeople，J2ME，列表视图，ArrayAdapter，列表项，
            我们，英国，印度};
    私人字符串my_sel_items;

    @覆盖
    公共无效的onCreate（包冰柱）{
        super.onCreate（冰柱）;
        的setContentView（R.layout.main）;
        my_sel_items =新的String（）;

        LVIEW =（ListView控件）findViewById（R.id.ListView01）;

        lView.setAdapter（新ArrayAdapter＆LT;字符串＆GT;（这一点，
                android.R.layout.simple_list_item_multiple_choice，lv_items））;
        lView.setChoiceMode（ListView.CHOICE_MODE_MULTIPLE）;

        lView.setOnItemClickListener（新OnItemClickListener（）{

            公共无效onItemClick（适配器视图为arg0，查看ARG1，INT ARG2，长ARG3）
            {
                //名单列表=新的ArrayList（）;
                my_sel_items =新的String（选定项目）;
                SparseBooleanArray一个= lView.getCheckedItemPositions（）;

                的for（int i = 0; I＆LT; lv_items.length;我++）
                {
                    如果（a.valueAt（i））的
                    {
                     / *
                        长VAL = lView.getAdapter（）getItemId（a.keyAt（ⅰ））。;
                        Log.v（迈德特，指数=+ val.toString（）
                             +项的值=+ lView.getAdapter（）的getItem（I））。
                        list.add（lView.getAdapter（）getItemId（（a.keyAt（ⅰ））））;
                     * /

                        my_sel_items = my_sel_items +，
                            +（字符串）lView.getAdapter（）的getItem（i）中。;
                    }
                }
                Log.v（价值观，my_sel_items）;

How to get selected multichoice list view data. i have a listview with multiple choice. and i want to store selected item of listview in string array. can anyone guide me how to store selected item of listview in string array.

SparseBooleanArray selectedItems = lv.getCheckedItemPositions();          
int id1 = lv.getCheckedItemPosition();        
Toast.makeText(getApplicationContext(), "" + id1, Toast.LENGTH_SHORT).show();

for (int i = 0; i < lv_arr.length; i++) {
    if (selectedItems.get(i)) {
        String[] getstring = (String) lv.getAdapter().getItem(
            selectedItems.keyAt(i));
        System.out.println(""+getstring));
    }
}

Hey I have used String for saving all checked items from the list..See the code below:

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.util.SparseBooleanArray;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.ListView;



public class ViewsActivity extends Activity

    private ListView lView;
    private String lv_items[] = { "Android", "iPhone", "BlackBerry",
            "AndroidPeople", "J2ME", "Listview", "ArrayAdapter", "ListItem",
            "Us", "UK", "India" };
    private String my_sel_items;

    @Override
    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        setContentView(R.layout.main);
        my_sel_items=new String();

        lView = (ListView) findViewById(R.id.ListView01);

        lView.setAdapter(new ArrayAdapter<String>(this,
                android.R.layout.simple_list_item_multiple_choice, lv_items));
        lView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);

        lView.setOnItemClickListener(new OnItemClickListener() {

            public void onItemClick(AdapterView arg0, View arg1, int arg2,long arg3)
            {
                //List list = new ArrayList();
                my_sel_items=new String("Selected Items");
                SparseBooleanArray a = lView.getCheckedItemPositions();

                for(int i = 0; i < lv_items.length ; i++)
                {
                    if (a.valueAt(i))
                    {
                     /*
                        Long val = lView.getAdapter().getItemId(a.keyAt(i));
                        Log.v("MyData", "index=" + val.toString()
                             + "item value="+lView.getAdapter().getItem(i));
                        list.add(lView.getAdapter().getItemId((a.keyAt(i))));
                     */

                        my_sel_items = my_sel_items + "," 
                            + (String) lView.getAdapter().getItem(i);
                    }
                }
                Log.v("values",my_sel_items);
            }
        });
    }
