Question

我正在使用Android Studio并设计如下布局。但是，我的ListView lv_comics仅显示1个项目的足够空间。我试图将layout_height设置为fill_parent，但它仍然不起作用。但是，当我将layout_height设置为特定大小时，它可以，但是当我切换到另一个屏幕大小时，这不是很好。有人可以帮帮我吗？

<android.support.v4.widget.SwipeRefreshLayout
xmlns:android="http://schemas.android.com/apk/res/android"

尝试这个动态计算高度

public static void setListViewHeight(ListView listView) {
    ListAdapter listAdapter = listView.getAdapter();
    if (listAdapter == null) {
        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);
        if (i == 0) {
            view.setLayoutParams(new ViewGroup.LayoutParams(desiredWidth, LayoutParams.WRAP_CONTENT));
        }
        view.measure(desiredWidth, MeasureSpec.AT_MOST);
        totalHeight += view.getMeasuredHeight();
    }
    ViewGroup.LayoutParams params = listView.getLayoutParams();
    params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));
    listView.setLayoutParams(params);
    listView.requestLayout();
}

Android - ListView的高度恰好适合1个ListView项目
