Question

我有一个列表视图，如果值为0，则附加图像，如果不是1。值0和1派生自SQLdatabase

我无法理解为什么第一行总是显示图像，如果它被标记为1，xml文本只有一个ImageView和textView，所以我不发送给你

  public class CustomViewAdapter extends CursorAdapter {

 public final int VIEW_TYPE_STARS=0;
 public final int VIEWTYPE_NORMAL=1;

public static class ViewHolder{
  public final  ImageView iv;
  public final  TextView tv;

    public ViewHolder(View view){
        iv = (ImageView) view.findViewById(R.id.urgent_finger);
        tv = (TextView) view.findViewById(R.id.text_v1);


    }
}



public CustomViewAdapter(Context context,Cursor c, int flag){
    super( context, c, flag);



}
@Override
public View newView(Context context, Cursor cursor, ViewGroup parent)   {

  int viewType = getItemViewType(cursor.getPosition());

    int layoutId=-1;
      layoutId = R.layout.textview_pretty_cool2_layout;




   View view= LayoutInflater.from(context).inflate(layoutId, parent, false);
 ViewHolder viewHolder = new ViewHolder(view);
 view.setTag(viewHolder);
   return view;



}

@Override
public void bindView(View view, Context context, Cursor cursor) {
ViewHolder viewHolder= (ViewHolder) view.getTag();

    String isCheckedMaybe = cursor.getString(cursor.getColumnIndexOrThrow(UcanContract.Tasks.COLUMN_URGENCY));
    Integer toString = Integer.parseInt(isCheckedMaybe);

     if(toString==0){
       viewHolder.iv.setImageResource(R.drawable.edit_undo);
        String tasksText = cursor.getString(cursor.getColumnIndexOrThrow(UcanContract.Tasks.COLUMN_TASKS));
        viewHolder.tv.setText(tasksText);

    }else if (toString == 1){
        String tasksText = cursor.getString(cursor.getColumnIndexOrThrow(UcanContract.Tasks.COLUMN_TASKS));
        viewHolder.tv.setText(tasksText);
    }

}
 }

Answer 1

设置Visisbility＆amp;的ImageView {GES} {G} {当你需要它时，你将它设置为TextView并且它会对你有用

customerAdapter的第一行不起作用
