Android更改Image of List的imageview

Question

我想单击列表时更改图像。点击列表中的某个位置，图像将发生变化。另一个列表位置的ImageView图像将是相同的，但我没有成功。

当我选择一个列表项目图像时，视图显示右侧图标图像，当我取消选择此位置时，ImageView显示一个箭头图像。

public View getView(final int position, View convertView, 
     final ViewGroup parent) { 
    // TODO Auto-generated method stub 

    View row = convertView; 
    if (row == null) { 

     LayoutInflater inflater = ((Activity) mContext).getLayoutInflater(); 
     row = inflater.inflate(mLayoutResourceId, parent, false); 

     mHolder = new BusinessHolder(); 

     mHolder.mTxt_STDNAME = (TextView) row 
       .findViewById(R.id.txt_stdName); 

     mHolder.mTxt_STDCOURSE = (TextView) row 
       .findViewById(R.id.txt_stdCourse); 

     mHolder.mTxt_STDYEAR = (TextView) row 
       .findViewById(R.id.txt_stdYear);   

     mHolder.mImageViewSelection = (ImageView) row 
       .findViewById(R.id.img_selection); 

     mHolder.mLin_layout=(LinearLayout)  row.findViewById(R.id.Layout_listText); 


     row.setTag(mHolder); 

    } else { 

     mHolder = (BusinessHolder) row.getTag(); 
    } 

     mHolder.mTxt_STDNAME.setText(FacultyDatabaseHalper.mStudentStudentName.get(position)); 

     mHolder.mTxt_STDCOURSE.setText(FacultyDatabaseHalper.mStudentCourse.get(position)); 

     mHolder.mTxt_STDYEAR.setText(FacultyDatabaseHalper.mStudentYear.get(position)); 


     mHolder.mLin_layout.setOnClickListener(new OnClickListener() { 

      @Override 
      public void onClick(View arg0) { 
       // TODO Auto-generated method stub 

       if(myposition.contains(String.valueOf(position))){ 


        myposition.remove(String.valueOf(position)); 


        mHolder.mImageViewSelection.setImageResource(R.drawable.arrow); 


        }else{ 


        myposition.add(String.valueOf(position)); 




         mHolder.mImageViewSelection.setImageResource(R.drawable.check); 

        } 

        notifyDataSetChanged(); 

      } 
     }); 

    return row; 
    } 

    public class BusinessHolder { 

    TextView mTxt_STDNAME, mTxt_STDYEAR, 
      mTxt_STDCOURSE; 
    ImageView mImageViewSelection; 

    LinearLayout mLin_layout; 

    } 

    }

你需要有听众对listView而不是在视图，这将给你的位置以及

Listview.setOnItemClickListener(new OnItemClickListener() { 
     public void onItemClick(AdapterView<?> parent, View view, 
       int position, long id) { 

     Object o = prestListView.getItemAtPosition(position); 
     prestationEco str=(prestationEco)o;//As you are using Default String Adapter 
     Toast.makeText(getBaseContext(),str.getTitle(),Toast.LENGTH_SHORT).show(); 
     } 
    });
