嘿，我也有类似的问题。我想显示一个列表视图，不滚动，我发现操纵参数工作，但效率低，会在不同的设备上表现不同。因此，这是我的一段调度代码，它实际上非常有效地完成了这个任务。

db = new dbhelper(this);

 cursor = db.dbCursor();
int count = cursor.getCount();
if (count > 0)
{    
LinearLayout linearLayout = (LinearLayout) findViewById(R.id.layoutId);
startManagingCursor(YOUR_CURSOR);

YOUR_ADAPTER(**or SimpleCursorAdapter **) adapter = new YOUR_ADAPTER(this,
    R.layout.itemLayout, cursor, arrayOrWhatever, R.id.textViewId,
    this.getApplication());

int i;
for (i = 0; i < count; i++){
  View listItem = adapter.getView(i,null,null);
  linearLayout.addView(listItem);
   }
}

注意:如果你使用这个，notifyDataSetChanged();将不会像预期的那样工作，因为视图将不会被重绘。 如果你需要变通，就这么做

adapter.registerDataSetObserver(new DataSetObserver() {

            @Override
            public void onChanged() {
                super.onChanged();
                removeAndRedrawViews();

            }

        });

下面是我的计算列表视图总高度的代码版本。这个对我很有用:

   public static void setListViewHeightBasedOnChildren(ListView listView) {
    ListAdapter listAdapter = listView.getAdapter();
    if (listAdapter == null || listAdapter.getCount() < 2) {
        // pre-condition
        return;
    }

    int totalHeight = 0;
    int widthMeasureSpec = View.MeasureSpec.makeMeasureSpec(BCTDApp.getDisplaySize().width, View.MeasureSpec.AT_MOST);
    int heightMeasureSpec = View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED);
    ViewGroup.LayoutParams lp = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);

    for (int i = 0; i < listAdapter.getCount(); i++) {
        View listItem = listAdapter.getView(i, null, listView);
        if (listItem instanceof ViewGroup) listItem.setLayoutParams(lp);
        listItem.measure(widthMeasureSpec, heightMeasureSpec);
        totalHeight += listItem.getMeasuredHeight();
    }

    totalHeight += listView.getPaddingTop() + listView.getPaddingBottom();
    totalHeight += (listView.getDividerHeight() * (listAdapter.getCount() - 1));
    ViewGroup.LayoutParams params = listView.getLayoutParams();
    params.height = totalHeight;
    listView.setLayoutParams(params);
    listView.requestLayout();
}

这是我的解决方案。我对Android平台相当陌生，我确信这有点笨拙，特别是在直接调用.measure和设置LayoutParams的部分。直接使用Height属性，但它是有效的。

你所要做的就是调用Utility.setListViewHeightBasedOnChildren(yourListView)，它将被调整大小，以完全适应其项目的高度。

public class Utility {
    public static void setListViewHeightBasedOnChildren(ListView listView) {
        ListAdapter listAdapter = listView.getAdapter();
        if (listAdapter == null) {
            // pre-condition
            return;
        }

        int totalHeight = listView.getPaddingTop() + listView.getPaddingBottom();

        for (int i = 0; i < listAdapter.getCount(); i++) {
            View listItem = listAdapter.getView(i, null, listView);
            if (listItem instanceof ViewGroup) {
                listItem.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
             }

             listItem.measure(0, 0);
             totalHeight += listItem.getMeasuredHeight();
        }

        ViewGroup.LayoutParams params = listView.getLayoutParams();
        params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));
        listView.setLayoutParams(params);
    }
}

这是DougW、Good Guy Greg和Paul的答案组合。我发现当尝试使用自定义列表视图适配器和非标准列表项时，这都是需要的，否则列表视图会导致应用程序崩溃(也会导致Nex的答案崩溃):

public void setListViewHeightBasedOnChildren(ListView listView) {
        ListAdapter listAdapter = listView.getAdapter();
        if (listAdapter == null) {
            return;
        }

        int totalHeight = listView.getPaddingTop() + listView.getPaddingBottom();
        for (int i = 0; i < listAdapter.getCount(); i++) {
            View listItem = listAdapter.getView(i, null, listView);
            if (listItem instanceof ViewGroup)
                listItem.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
            listItem.measure(0, 0);
            totalHeight += listItem.getMeasuredHeight();
        }

        ViewGroup.LayoutParams params = listView.getLayoutParams();
        params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));
        listView.setLayoutParams(params);
    }

以下是对@djunod的回答的小修改，我需要使它完美地工作:

public static void setListViewHeightBasedOnChildren(ListView listView)
{
    ListAdapter listAdapter = listView.getAdapter();
    if(listAdapter == null) return;
    if(listAdapter.getCount() <= 1) return;

    int desiredWidth = MeasureSpec.makeMeasureSpec(listView.getWidth(), MeasureSpec.AT_MOST);
    int totalHeight = 0;
    View view = null;
    for(int i = 0; i < listAdapter.getCount(); i++)
    {
        view = listAdapter.getView(i, view, listView);
        view.measure(desiredWidth, MeasureSpec.UNSPECIFIED);
        totalHeight += view.getMeasuredHeight();
    }
    ViewGroup.LayoutParams params = listView.getLayoutParams();
    params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));
    listView.setLayoutParams(params);
    listView.requestLayout();
}

你不应该把ListView放到ScrollView中因为ListView已经是一个ScrollView了。这就像把一个ScrollView放到一个ScrollView中。

你想要完成什么?
