android-如何强制listView的高度为大小,以便每一行都可见？

我嵌套了listView.如何强制将listView的高度设置为大小,以使每一行都可见？
ListView嵌套在ScrollView内,所以滚动不适用于ListView,因此我需要使所有项目在嵌套在ScrollView的ListView内可见(上面还有下面的东西).

解决方法:

计算listView的高度

public static void setListViewHeightBasedOnChildren(ListView listView) {
    ListAdapter listAdapter = listView.getAdapter();
    if (listAdapter == null) {
        // pre-condition
        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));
    listView.setLayoutParams(params);
    listView.requestLayout();
}

将listview对象传递给此方法.

 setListViewHeightBasedOnChildren(listView)
