Java 将OnClickListener添加到多项选择列表视图

我的应用程序有一个可选择多个元素的多选列表视图。我已经创建了一个SparseBooleanArray来存储是否单击了不同的元素，但是我不确定如何实现OnClickListener

public class ListOfMajors extends Activity {

    public static boolean aerospace, agricultural, biomed, chem, civil, computer, electrical, physics, environment, industrial, materials, mechanical;
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);


        setContentView(R.layout.majorslist);
        ListView mylist = (ListView) findViewById(R.id.majorslist);
        String[] list={"Aerospace Engineering","Agricultural Engineering","Biomedical Engineering","Chemical Engineering","Civil Engineering",
                        "Computer Engineering","Electrical Engineering","Engineering Physics","Environmental Engineering","Industrial Engineering",
                        "Materials Engineering","Mechanical Engineering"};
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(ListOfMajors.this,android.R.layout.simple_list_item_multiple_choice,list);
        mylist.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
        mylist.setAdapter(adapter);

        SparseBooleanArray checkedItems = mylist.getCheckedItemPositions();
        if (checkedItems!= null){
            for(int i=0; i<checkedItems.size();i++){
                if(checkedItems.valueAt(0)){
                    aerospace = true;
                }
                if(checkedItems.valueAt(1)){
                    agricultural = true;
                }
                if(checkedItems.valueAt(2)){
                    biomed = true;
                }
                if(checkedItems.valueAt(3)){
                    chem = true;
                }
                if(checkedItems.valueAt(4)){
                    civil = true;
                }
                if(checkedItems.valueAt(5)){
                    computer = true;
                }
                if(checkedItems.valueAt(6)){
                    electrical = true;
                }
                if(checkedItems.valueAt(7)){
                    physics = true;
                }
                if(checkedItems.valueAt(8)){
                    environment = true;
                }
                if(checkedItems.valueAt(9)){
                    industrial = true;
                }
                if(checkedItems.valueAt(10)){
                    materials = true;
                }
                if(checkedItems.valueAt(11)){
                    mechanical = true;
                }
            }
        }

    }


}

公共类ListOfMajors扩展活动{
公共航空航天、农业、生物医学、化学、民用、计算机、电气、物理、环境、工业、材料、机械；
创建时的公共void（Bundle savedInstanceState）{
super.onCreate（savedInstanceState）；
setContentView（R.layout.MajorList）；
ListView mylist=（ListView）findViewById（R.id.MajorList）；
字符串[]列表={“航空航天工程”、“农业工程”、“生物医学工程”、“化学工程”、“土木工程”，
“计算机工程”、“电气工程”、“工程物理”、“环境工程”、“工业工程”，
“材料工程”、“机械工程”}；
ArrayAdapter=新的ArrayAdapter（ListOfMajors.this，android.R.layout.simple\u list\u item\u多项选择，list）；
mylist.setChoiceMode（ListView.CHOICE\u MODE\u MULTIPLE）；
mylist.setAdapter（适配器）；
SparseBooleanArray checkedItems=mylist.getCheckedItemPositions（）；
if（checkedItems！=null）{
for（int i=0；i请删除如下可怕的for循环：-）

boolean[]mItemState；
创建时的公共void（Bundle savedInstanceState）{
super.onCreate（savedInstanceState）；
setContentView（R.layout.MajorList）；
ListView mylist=（ListView）findViewById（R.id.MajorList）；
最终字符串[]列表={“航空航天工程”、“农业工程”，
“生物医学工程”、“化学工程”、“土木工程”，
“计算机工程”、“电气工程”、“工程物理”，
“环境工程”、“工业工程”，
“材料工程”、“机械工程”}；
mItemState=新布尔值[list.length]
ArrayAdapter=新的ArrayAdapter（ListOfMajors.this，android.R.layout.simple\u list\u item\u多项选择，list）；
mylist.setChoiceMode（ListView.CHOICE\u MODE\u MULTIPLE）；
myList.setOnItemClickListener（新的AdapterView.OnItemClickListener（）{
@凌驾
public void onItemClick（AdapterView父对象、视图、整型位置、长id）{
//切换状态
mItemState[位置]=！mItemState[位置]；
if（斜接状态[位置]）
Log.d（“已选择onItemClick”、“Major”+列表[位置]+”）；
其他的
Log.d（“已取消选择主菜单“+列表[位置]+”）；
}
});
mylist.setAdapter（适配器）；
}

基本上，所有专业都设置为特定索引（从0开始），其选中状态保存在mItemState数组中。每次单击列表中的项目时，状态都会切换

boolean[] mItemState;

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);


    setContentView(R.layout.majorslist);
    ListView mylist = (ListView) findViewById(R.id.majorslist);
    final String[] list={"Aerospace Engineering","Agricultural Engineering",
            "Biomedical Engineering","Chemical Engineering","Civil Engineering",
            "Computer Engineering","Electrical Engineering","Engineering Physics", 
            "Environmental Engineering","Industrial Engineering",
            "Materials Engineering","Mechanical Engineering"};
    mItemState = new boolean[list.length]
    ArrayAdapter<String> adapter = new ArrayAdapter<String>(ListOfMajors.this,android.R.layout.simple_list_item_multiple_choice,list);
    mylist.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);

    myList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            // Toggle the state
            mItemState[position] = !mItemState[position];
            if (mItemState[position])
                Log.d("onItemClick","Major " + list[position] + " has been selected");
            else
                Log.d("onItemClick","Major " + list[position] + " has been deselected");
        }
    });

    mylist.setAdapter(adapter); 
}
