如果向上/向下滚动，带EditText的Android ListView在编辑值中丢失

有这么多类似的问题，但没有一个涵盖我的情况。 我有一个带有EditText的ListView，它处于编辑阶段。 如果我滚动列表，使“编辑中”行消失，我将丢失输入值

当用户从一行移动到另一行时，我已经在使用OnFocusChangeListener“存储”更改的值，但当编辑行离开视图时，不会触发此事件

这是我的实际代码：

public enum FieldType {
    UNDEFINED, TITLE, EDIT, CHECK;
}

public enum EditType {
    INTEGER, FLOAT
}

private abstract class BaseField {
    public FieldType type = FieldType.UNDEFINED;
}       

private class TitleField extends BaseField {
    public int titleID;

    public TitleField(int titleID) {
        this.type = FieldType.TITLE;
        this.titleID = titleID;
    }
}

private class EditField extends BaseField {
    public String code;
    public int captionID;
    public String value;
    public String unit;
    public String decimal;
    public String minimum;
    public String maximum;

    public EditField(String code, int captionID, String value, String unit, String decimal, String minimum, String maximum) {
        this.type = FieldType.EDIT;
        this.code = code;
        this.captionID = captionID;
        this.value = value;
        this.unit = unit;
        this.decimal = decimal;
        this.minimum = minimum;
        this.maximum = maximum;
    }
}

private class CheckField extends BaseField {
    public String code;
    public int captionID;
    public boolean value;
    public String unit;

    public CheckField(String code, int captionID, boolean value, String unit) {
        this.type = FieldType.CHECK;
        this.code = code;
        this.captionID = captionID;
        this.value = value;
        this.unit = unit;
    }
}

private class TitleFieldViewHolder {
    public TextView textTitle = null;
}

private class EditFieldViewHolder {
    public TextView textCode = null;
    public TextView textCaption = null;
    public EditText editValue = null;
    public TextView textUnit = null;
}

private class CheckFieldViewHolder {
    public TextView textCode = null;
    public TextView textCaption = null;
    public CheckBox checkValue = null;
    public TextView textUnit = null;
}

您必须为每一行设置唯一的标记并使用thatShayan，您的意思是我必须为earch EDIT row创建一个新的convertView和editHolder？我不明白你的句子。谢谢你的支持。。。如果可以帮助我把整个项目推到这个链接
