如何从多选列表视图中选择项目 [英] How to get Selected items from Multi Select List View

问题描述

我使用一个数组适配器和本时添加的String数组列表，该列表是多选，我怎样才能获得列表项的值，点击？

I am using an array adapter and to this am adding an array list of string s , the list is multi select , How can i get the values of list items clicked ?

my_contacts_list.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
ArrayAdapter<String> adapter=new ArrayAdapter<String>(this, android.R.layout.simple_list_item_multiple_choice,conts_list);
  my_contacts_list.setAdapter(adapter);

我试图做到这一点，

I was trying to do this ,

SparseBooleanArray positions = my_contacts_list.getCheckedItemPositions();
  int size=positions.size();
  int i=0;
  while(i <= size){
   conts_list.get(positions.get(i));
   i++;
  }

但position.get（i）是一个数组列表，如何检索选定的项目呢？

But position.get(i) is an array list , how to retrieve the selected items then ?

推荐答案

SparseBooleanArray.get返回一个布尔值，但我相信你需要检查它的每一个位置的列表，如：

SparseBooleanArray.get returns a boolean, but I believe you need to check it for each position in your list, e.g.

int len = listView.getCount();
SparseBooleanArray checked = listView.getCheckedItemPositions();
for (int i = 0; i < len; i++)
 if (checked.get(i)) {
  String item = cont_list.get(i);
  /* do whatever you want with the checked item */
 }
