如何计算不同高度的ListItem ListView的高度在android系统？ [英] how to calculate listview height of different height listitem in android?

问题描述

这code是工作，但问题是ListView控件ListView中的每个产品的ListView不显示，因为大的高度ListView项获得这个空间的差异让最后一个项目。

这里是code：

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();

}

这里是屏幕

请帮我如何获得每个单元的列表视图的高度，并计算出的ListView heght？
在此先感谢..

推荐答案

你的函数由

公共静态无效getTotalHeightofListView（ListView控件ListView控件）{

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();

}
