问题

This code is work but the issue is in ListView each item of ListView is diff so last item of ListView is not display because big height ListView item get this space .

here is 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();

}

Here is screen

回答1:

your function replace by

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();
}

ANS use this

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

on your code

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