我已经实现了一个自定义SimpleCursorAdapter，以便将图像和文本插入到 myListView中，但是当用户滚动时图像会四处移动。我怎样才能让他们留在原地？这是我的代码（为简单起见，我将其剥离）：

 final class mySimpleCursorAdapter extends SimpleCursorAdapter {

public mySimpleCursorAdapter(Context context, int layout, Cursor cur,
        String[] from, int[] to) {
   super(context, layout, cur, from, to);
   mContext = context;
   mLayoutInflater = LayoutInflater.from(context); 
 }

@Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
    View v = mLayoutInflater.inflate(R.layout.row, parent, false);
    return v;
}


@Override
public void bindView(View v, Context context, Cursor c) {

        ImageView bar11 = (ImageView) v.findViewById(R.id.bar);
        ImageView bar12 = (ImageView) v.findViewById(R.id.bar2);
           ImageView bar13 = (ImageView) v.findViewById(R.id.bar3);
        TextView sign = (TextView) v.findViewById(R.id.text3);                        
               sign.setText(currency);

            if (someValue == 0){
                bar11.setVisibility(View.GONE);
            }

          if (someValue == 1){
                bar12.setVisibility(View.VISIBLE);
            }        

          if (someValue == 2){
                bar13.setVisibility(View.VISIBLE);
            }   

   }
 }

行.xml

  <?xml version="1.0" encoding="utf-8"?>

 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

  android:layout_width="fill_parent"

  android:layout_height="wrap_content">

 <ImageView 
  android:id="@+id/bar"

  android:layout_width="fill_parent"

  android:layout_height="65dp"

  android:background="@drawable/greenbar"/>

    <ImageView 
  android:id="@+id/bar2"

  android:layout_width="fill_parent"

  android:layout_height="65dp"

  android:background="@drawable/two"/>

    <ImageView 
  android:id="@+id/bar3"

  android:layout_width="fill_parent"

  android:layout_height="65dp"

  android:background="@drawable/two"/>


 <TextView

  android:id="@+id/text3"

  android:layout_width="wrap_content"

  android:layout_height="fill_parent"

  android:layout_alignParentRight="true"

  android:layout_centerVertical="true"/>

 </RelativeLayout>

列表.xml

  <?xml version="1.0" encoding="utf-8"?>
 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" 
android:id="@+id/expense"
android:background="@drawable/expensebackgroundblue">


<ListView
    android:id="@+id/contentlist"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="#00000000" 
    android:cacheColorHint="#00000000" >
</ListView>

 </RelativeLayout>

问题正在发生，因为视图回收您需要做些什么来将视图可见性设置为可见或像这样消失

@Override
public void bindView(View v, Context context, Cursor c) {

    ImageView bar11 = (ImageView) v.findViewById(R.id.bar);
    ImageView bar12 = (ImageView) v.findViewById(R.id.bar2);
       ImageView bar13 = (ImageView) v.findViewById(R.id.bar3);
    TextView sign = (TextView) v.findViewById(R.id.text3);                        
           sign.setText(currency);

        if (someValue == 0){
            bar11.setVisibility(View.GONE);
        }else
        {
            bar11.setVisibility(View.VISIBLE);
        }

        if (someValue == 1){
            bar12.setVisibility(View.VISIBLE);
        }else
        {
            bar12.setVisibility(View.GONE);
         }        

      if (someValue == 2){
            bar13.setVisibility(View.VISIBLE);
        }else
        {
             bar13.setVisibility(View.GONE);
        }
}
