一、android listView的每一个item布局高度不一样

1.获取listView的宽度

2.给item的measure设置参数是listView的宽度就可以获取到真正每一个item的高度

public void setListViewHeightBasedOnChildren(ListView listView1) {

BaseAdapter listAdapter = (BaseAdapter) listView1.getAdapter();

if (listAdapter == null) {

return;

}

int totalHeight = 0;

//获取listView的宽度

ViewGroup.LayoutParams params = listView1.getLayoutParams();

int  listViewWidth  = getActivity().getWindowManager().getDefaultDisplay().getWidth();

int widthSpec = View.MeasureSpec.makeMeasureSpec(listViewWidth, View.MeasureSpec.AT_MOST);

for (int i = 0; i < listAdapter.getCount(); i++) {

View listItem = listAdapter.getView(i, null, listView1);

//给item的measure设置参数是listView的宽度就可以获取到真正每一个item的高度

listItem.measure(widthSpec, 0);

totalHeight += listItem.getMeasuredHeight();

}

params.height = totalHeight

+ (listView1.getDividerHeight() * (listAdapter.getCount() + 1));

listView1.setLayoutParams(params);

}
