我具有其中有打开和关闭的一些额外信息一些标签的布局。其中的一个标记，显示了一个列表视图。但是，而不是显示所有的元素，它仅显示一个接一个带滚动功能。我只是想表明在ListView中的所有项目。

在屏幕的正常状态：

点击标签之后：

这是屏幕的关键XML：

这是适配器的code：

 的ListView列表=（ListView控件）findViewById（R.id.lv_schoolinfo）;ArrayList的＆LT;＆参数GT; PARAMS = l.getSchools（）;ArrayList的＆LT;串GT;学校=新的ArrayList＆LT;串GT;（）;的for（int i = 0; I＆LT; params.size（）;我++）{    schools.add（params.get（ⅰ）.getName（））;}ArrayAdapter＆LT;串GT;适配器=新ArrayAdapter＆LT;串GT;（这一点，android.R.layout.simple_list_item_1，学校）;list.setAdapter（适配器）; 

解决方案

使用这个类公用事业

 公共类工具{    公共静态无效setListViewHeightBasedOnChildren（ListView控件ListView控件）        {            ListAdapter listAdapter = listView.getAdapter（）;            如果（listAdapter == NULL）                {                    返回;                }            INT totalHeight = 0;            INT desiredWidth = MeasureSpec.makeMeasureSpec（listView.getWidth（），MeasureSpec.AT_MOST）;            的for（int i = 0; I＆LT; listAdapter.getCount（）;我++）                {                    查看的listItem = listAdapter.getView（I，空，ListView控件）;                    listItem.measure（desiredWidth，MeasureSpec.UNSPECIFIED）;                    totalHeight + = listItem.getMeasuredHeight（）;                }            ViewGroup.LayoutParams PARAMS = listView.getLayoutParams（）;            params.height = totalHeight +（listView.getDividerHeight（）*（listAdapter.getCount（） -  1））+ 20;            listView.setLayoutParams（PARAMS）;            listView.requestLayout（）;        }} 

和使用这个类里面像这样

  list1.setAdapter（imageAdapteritem）;Utility.setListViewHeightBasedOnChildren（list1的）; 

这将扩大您的列表，以孩子的总数您可以同时查看所有的人：）

I have a layout in which there are some tags that opens and closes some extra information. One of these tags, shows a listview. But instead of showing all the elements, it shows just one by one with scrolling enabled. I just want to show all the items in the listview.

Normal state of the screen:

After clicking on the tag:

This is the critical xml of the screen:

        <TextView
            android:id="@+id/tv_school"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_alignLeft="@+id/tv_basic"
            android:layout_below="@+id/divider3a"
            android:paddingBottom="10dip"
            android:paddingTop="10dip"
            android:text="School Info"
            android:textColor="#5E5E60"
            android:onClick="animationText"
            android:clickable="true" />

        <ImageView
            android:id="@+id/uparrow3"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentRight="true"
            android:layout_below="@+id/divider3a"
            android:layout_above="@+id/divider3b"
            android:layout_marginRight="10dip"
            android:layout_marginTop="10dip"
            android:layout_marginBottom="10dip"
            android:src="@drawable/up"
            android:visibility="invisible" />

        <ImageView
            android:id="@+id/downarrow3"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentRight="true"
            android:layout_below="@+id/divider3a"
            android:layout_above="@+id/divider3b"
            android:layout_marginRight="10dip"
            android:layout_marginTop="10dip"
            android:layout_marginBottom="10dip"
            android:src="@drawable/down" />

        <ImageView
            android:id="@+id/divider3b"
            android:layout_width="match_parent"
            android:layout_height="1dp"
            android:layout_below="@+id/tv_school"
            android:visibility="invisible"
            android:background="@android:color/darker_gray"/>

        <ListView
            android:id="@+id/lv_schoolinfo"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_below="@+id/divider3b"
            android:layout_alignLeft="@+id/tv_basic"
            android:paddingBottom="10dip"
            android:paddingTop="10dip"
            android:paddingRight="10dip"
            android:scrollbars="none"
            android:orientation="vertical"
            android:visibility="invisible" />


        <ImageView
            android:id="@+id/divider4"
            android:layout_width="match_parent"
            android:layout_height="1dp"
            android:layout_below="@+id/tv_school"
            android:background="@android:color/darker_gray"/>

And this is the code of the adapter:

ListView list = (ListView) findViewById(R.id.lv_schoolinfo);
ArrayList<Param> params = l.getSchools();
ArrayList<String> schools = new ArrayList<String>();
for(int i=0; i<params.size(); i++){
    schools.add(params.get(i).getName());
}
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, schools);
list.setAdapter(adapter);

Use this class as utility

public class Utility 
{
    public static void setListViewHeightBasedOnChildren(ListView listView) 
        {
            ListAdapter listAdapter = listView.getAdapter();
            if (listAdapter == null) 
                {
                    return;
                }
            int totalHeight = 0;
            int desiredWidth = MeasureSpec.makeMeasureSpec(listView.getWidth(), MeasureSpec.AT_MOST);
            for (int i = 0; i < listAdapter.getCount(); i++) 
                {
                    View listItem = listAdapter.getView(i, null, listView);
                    listItem.measure(desiredWidth, MeasureSpec.UNSPECIFIED);
                    totalHeight += listItem.getMeasuredHeight();
                }
            ViewGroup.LayoutParams params = listView.getLayoutParams();
            params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1))+20;
            listView.setLayoutParams(params);
            listView.requestLayout();
        }
}

and use this classs like this

list1.setAdapter(imageAdapteritem);
Utility.setListViewHeightBasedOnChildren(list1);

this will expand your list to the total number of childs you can view all of them at same time :)
