如何在android中计算不同高度listitem的listview高度？

Question

此代码有效，但问题是在ListView中，ListView的每个项目都是差异，因此不显示ListView的最后一项，因为大高度ListView项目获得此空间。

这是代码：

public static void setListViewHeightBasedOnChildren(ListView listView,DownloadAdapter adapter,LinearLayout layDownloads) {

ListAdapter mAdapter = adapter;

    int totalHeight = 0,h=0;
    int listWidth=listView.getMeasuredWidth();

    for (int i = 0; i < mAdapter.getCount(); i++) {
        View mView = mAdapter.getView(i, null, listView);

    mView.measure(
                MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED),
                MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
        h=mView.getMeasuredHeight();
        totalHeight += mView.getMeasuredHeight();

    }

    ViewGroup.LayoutParams params = listView.getLayoutParams();
    params.height = totalHeight
            + (listView.getDividerHeight() * (mAdapter.getCount() - 1))+h;
    listView.setLayoutParams(params);
    listView.requestLayout();

}

这是屏幕

请帮助我如何获得每个单元格列表视图的高度并计算listview的高度？ 提前致谢..

您的功能替换为

public static void getTotalHeightofListView(ListView listView) {

    ListAdapter mAdapter = listView.getAdapter();

    int totalHeight = 0;
    int listWidth = listView.getMeasuredWidth();

    for (int i = 0; i < mAdapter.getCount(); i++) {
        View mView = mAdapter.getView(i, null, listView);

        mView.measure(MeasureSpec.makeMeasureSpec(listWidth, MeasureSpec.EXACTLY),
                MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));

        totalHeight += mView.getMeasuredHeight();
        Log.w("HEIGHT" + i, String.valueOf(totalHeight));

    }

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

<强> ANS 使用这个

mView.measure（MeasureSpec.makeMeasureSpec（listWidth，MeasureSpec.EXACTLY），MeasureSpec.makeMeasureSpec（0，MeasureSpec.UNSPECIFIED））;

代码

mView.measure（MeasureSpec.makeMeasureSpec（0，MeasureSpec.UNSPECIFIED），MeasureSpec.makeMeasureSpec（0，MeasureSpec.UNSPECIFIED））;
