</LinearLayout>

这是我的适配器

   @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View v = convertView;
        viewHolder vh = null;

        if(v == null){

            vh = new viewHolder();
            LayoutInflater vi = (LayoutInflater)getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            v = vi.inflate(R.layout.schedual_listview,null);
            v.setBackgroundResource(R.drawable.custom_middle_listview);

            vh.wrapper = (LinearLayout) v.findViewById(R.id.wrapper);
            vh.imgDay = (ImageView) v.findViewById(R.id.imgDay);
            vh.customView = (CustomView_Schedule) v.findViewById(R.id.view);
            vh.txtTime1 = (TextView) v.findViewById(R.id.txtTime1);
            vh.txtTime2 = (TextView) v.findViewById(R.id.txtTime2);
            vh.txtTime3 = (TextView) v.findViewById(R.id.txtTime3);
            vh.txtTime4 = (TextView) v.findViewById(R.id.txtTime4);
            vh.txtTime5 = (TextView) v.findViewById(R.id.txtTime5);
            vh.txtSubject1 = (TextView) v.findViewById(R.id.txtSubject1);
            vh.txtSubject2 = (TextView) v.findViewById(R.id.txtSubject2);
            vh.txtSubject3 = (TextView) v.findViewById(R.id.txtSubject3);
            vh.txtSubject4 = (TextView) v.findViewById(R.id.txtSubject4);
            vh.txtSubject5 = (TextView) v.findViewById(R.id.txtSubject5);


            v.setTag(vh);

        }else{
            vh = (viewHolder)v.getTag();
        }

        Schedule_lvItem schedule_lvItem = scheduleLvItems.get(position);

        vh.imgDay.setImageResource(schedule_lvItem.getDay());
        vh.customView.setSubjectData(schedule_lvItem.getSubjectData());
        vh.txtTime1.setText("09:00");
        vh.txtTime2.setText("10:30");
        vh.txtTime3.setText("12:00");
        vh.txtTime4.setText("13:30");
        vh.txtTime5.setText("15:00");
        vh.txtSubject1.setText("ENGLISH IV");
        vh.txtSubject2.setText("MACRO");
        vh.txtSubject3.setText("STRATEGIC TECHNOLOGY MANAGEMENT");
        vh.txtSubject4.setText("DATA COMMUNICATION");
        vh.txtSubject5.setText("OBJECT ORIENTED PROGRAMMING");

        AbsListView.LayoutParams layoutParams = new AbsListView.LayoutParams(
                AbsListView.LayoutParams.FILL_PARENT,
                schedule_lvItem.getCurrentHeight()
        );
        vh.wrapper.setLayoutParams(layoutParams);

        schedule_lvItem.setWrapper(vh.wrapper);

        v.setTag(vh);

        return v;
    }

    public class viewHolder{
        LinearLayout wrapper;
        ImageView imgDay;
        CustomView_Schedule customView;
        TextView txtTime1;
        TextView txtTime2;
        TextView txtTime3;
        TextView txtTime4;
        TextView txtTime5;
        TextView txtSubject1;
        TextView txtSubject2;
        TextView txtSubject3;
        TextView txtSubject4;
        TextView txtSubject5;
    }

第一个LinearLayout在屏幕上可见，而其他不在

注意::这适用于ListView的单行项目

我目前正在使用幻灯片动画创建可扩展的ListView。

此布局将包含展开效果之前和之后的作用。

我做错了什么？ PLZ建议。

由于FILL_PARENT：

，您的第一个linearlayout正在从其父级获取完整空间

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              xmlns:custom="http://schemas.android.com/apk/res/com.prototype.auinsight.schedual_listview"
              android:layout_width="fill_parent"
              android:layout_height="wrap_content"
              android:orientation="vertical"
              android:id="@+id/wrapper">

    <LinearLayout
            android:orientation="horizontal"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent">  <===  here

将其替换为：android:layout_height="wrap_content"应解决您的问题。

使用带有heith的父级wrap_content和高度为fill_parent的子级具有不可预测的结果，因为两者都依赖于它们的大小。

顺便说一下，“FILL_PARENT”已被弃用，它已被重命名为“MATCH_PARENT”。
