Question

我有一个自定义列表视图，其中包含3个textview和5个imageview（星号）。前两个textview是可见的，第三个是不可见的。我从服务器获取数据并将其放入listview无论多少。

我想要什么

如果我点击任何一个星（1或2或3或4或5）我想从textview获取隐藏的id。点击后，星形图像视图会更改图像。假设我点击第三颗星然后将评定3颗星，其他将被评为未评级。

我做了什么

现在我可以从服务器获取数据并将其放入listview但是假设我点击任何项目的星号，然后最后一个项目的星星改变他们的图像而不是点击的项目。它从隐藏的textview中获取最后一个id。

这是我的代码。

public class MyArrayAdapter extends ArrayAdapter<Student> {
StudentWrapper StudentWrapper = null;
Context context;
int layoutResourceId;
Student student;
ArrayList<Student> students = new ArrayList<Student>();

 public MyArrayAdapter(Context context, int layoutResourceId,ArrayList<Student> studs)   {
    super(context, layoutResourceId, studs);
    this.layoutResourceId = layoutResourceId;
    this.context = context;
    this.students = studs;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    View item = convertView;



    if (item == null) {
        LayoutInflater inflater = ((Activity) context).getLayoutInflater();
        item = inflater.inflate(layoutResourceId, parent, false);
        StudentWrapper = new StudentWrapper();
        StudentWrapper.menuname = (TextView) item.findViewById(R.id.title);
        StudentWrapper.hotelname = (TextView) item.findViewById(R.id.artist);   
        StudentWrapper.menuid = (TextView) item.findViewById(R.id.tvhotelid);   
        StudentWrapper.firstStar = (ImageView)item.findViewById(R.id.hotelListFirstStar);
        StudentWrapper.secondStar = (ImageView)item.findViewById(R.id.hotelListSecondStar);
        StudentWrapper.thirdStar = (ImageView)item.findViewById(R.id.hotelListThirdStar);
        StudentWrapper.fourthStar = (ImageView)item.findViewById(R.id.hotelListFourthStar);
        StudentWrapper.fifthStar = (ImageView)item.findViewById(R.id.hotelListFifthStar);
        StudentWrapper.firstStar.setFocusable(false);
        StudentWrapper.secondStar.setFocusable(false);
        StudentWrapper.thirdStar.setFocusable(false);
        StudentWrapper.fourthStar.setFocusable(false);
        StudentWrapper.fifthStar.setFocusable(false);
        item.setTag(StudentWrapper);
    } else {
        StudentWrapper = (StudentWrapper) item.getTag();
    }

    student = students.get(position);
    StudentWrapper.menuname.setText(student.getMenuName());
    StudentWrapper.hotelname.setText(student.gethotenName());
    StudentWrapper.menuid.setText(String.valueOf(student.getMenuId()));

    StudentWrapper.fifthStar.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            Toast.makeText(context, "Edit", Toast.LENGTH_LONG).show();
            StudentWrapper.firstStar.setImageResource(R.drawable.rated);
            StudentWrapper.secondStar.setImageResource(R.drawable.rated);
            StudentWrapper.thirdStar.setImageResource(R.drawable.rated);
            StudentWrapper.fourthStar.setImageResource(R.drawable.rated);
            StudentWrapper.fifthStar.setImageResource(R.drawable.rated);
        }
    });

    StudentWrapper.secondStar.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            StudentWrapper.firstStar.setImageResource(R.drawable.rated);
            StudentWrapper.secondStar.setImageResource(R.drawable.rated);
            StudentWrapper.thirdStar.setImageResource(R.drawable.unrated);
            StudentWrapper.fourthStar.setImageResource(R.drawable.unrated);
            StudentWrapper.fifthStar.setImageResource(R.drawable.unrated);
            Toast.makeText(context, "Delete"+student.getMenuId(), Toast.LENGTH_LONG).show();
        }
    });
    StudentWrapper.firstStar.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            StudentWrapper.firstStar.setImageResource(R.drawable.rated);
            StudentWrapper.secondStar.setImageResource(R.drawable.unrated);
            StudentWrapper.thirdStar.setImageResource(R.drawable.unrated);
            StudentWrapper.fourthStar.setImageResource(R.drawable.unrated);
            StudentWrapper.fifthStar.setImageResource(R.drawable.unrated);
            Toast.makeText(context, "Delete"+student.getMenuId(), Toast.LENGTH_LONG).show();
        }
    });
    StudentWrapper.fourthStar.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
                 StudentWrapper.firstStar.setImageResource(R.drawable.rated);
            StudentWrapper.secondStar.setImageResource(R.drawable.rated);
            StudentWrapper.thirdStar.setImageResource(R.drawable.rated);
            StudentWrapper.fourthStar.setImageResource(R.drawable.rated);
            StudentWrapper.fifthStar.setImageResource(R.drawable.unrated);
            Toast.makeText(context, "Delete"+student.getMenuId(), Toast.LENGTH_LONG).show();
        }
    });
    StudentWrapper.thirdStar.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
                   StudentWrapper.firstStar.setImageResource(R.drawable.rated);
            StudentWrapper.secondStar.setImageResource(R.drawable.rated);
            StudentWrapper.thirdStar.setImageResource(R.drawable.rated);
            StudentWrapper.fourthStar.setImageResource(R.drawable.unrated);
            StudentWrapper.fifthStar.setImageResource(R.drawable.unrated);
            Toast.makeText(context, "Delete"+student.getMenuId(), Toast.LENGTH_LONG).show();
        }
    });

    return item;

}

static class StudentWrapper {
    TextView menuid;
    TextView menuname;
    TextView hotelname;
    ImageView firstStar;
    ImageView secondStar;
    ImageView thirdStar;
    ImageView fourthStar;
    ImageView fifthStar;
}

}

如果我点击任何项目中的任何星星，那么它会反映最后一项。我想更改该项目的imageview，并希望从该项目的textview获取文本请给我任何提示或参考

我在listview存在的Activity中执行此操作，而不是在customadapter中。

    adapterListview = new ListArrayAdapter(this, items);
    this.listview.setAdapter(adapterListview);

    listview.setOnItemClickListener(new OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> parent, View view,
                int position, long id) {

            // global variable
            idItem = (int) id;

            switch (idItem) {

            case 0:
               // set your text and image for this item
            break;

            case 1:
               // set your text and image for this item

            break;

            case 2:
               // set your text and image for this item

            break;

            case 3:
               // set your text and image for this item

            break;
         }
       }
     });

id = 0是第一颗星，id = 1是第二颗星，依此类推......

可能是你的ListView正在接受触摸事件，并且正在转移到每个孩子。因此所有的星星都被突出显示

onClick上的ListView和ListItem行为
