Wrong total height of ListView when TextView hasn't got single line

I have got a small issue in my code... The problem is that I need to add height of each ListView item (cause I have got it in ScrollView and I don't want to have got double scroll places...).
This is my code which allows me to do that:
public static void getListViewSize(ListView myListView) {
ListAdapter myListAdapter = myListView.getAdapter();
if (myListAdapter == null) {
//do nothing return null
return;
}
//set listAdapter in loop for getting final size
int totalHeight = 0;
for (int size = 0; size < myListAdapter.getCount(); size++) {
View listItem = myListAdapter.getView(size, null, myListView);
listItem.measure(0, 0);
totalHeight += listItem.getMeasuredHeight();
totalHeight += listItem.getPaddingTop() + listItem.getPaddingBottom();
}
//setting listview item in adapter
ViewGroup.LayoutParams params = myListView.getLayoutParams();
params.height = totalHeight + (myListView.getDividerHeight() * (myListAdapter.getCount() - 1));
myListView.setLayoutParams(params);
// print height of adapter on log
Log.i("height of listItem:", String.valueOf(totalHeight));
}
And I call this function here:
final ReceivedAttachementsListArrayAdapter adapter = new ReceivedAttachementsListArrayAdapter(getActivity(), attachements);
mReceivedAttachementsListView.setAdapter(adapter);
ViewHelper.getListViewSize(mReceivedAttachementsListView);
When my TextView is 1 line length or 3 line length, totalHeight of ListView items still gives me the same result.
Any idea to improve my method?

How to set listview height inside scrollview properly?

I used listview inside scrollview and used this code to update listview height:
// method to expand the height of listview
public void updateListViewHeight(ListView list) {
CustomeAdapter myListAdapter = (CustomeAdapter) list.getAdapter();
if (myListAdapter == null) {
return;
}
// get listview height
int totalHeight = 0;
// int adapterCount = myListAdapter.getCount();
for (int size = 0; size < Math.max(shoutsList.size(), postsList.size()); size++) {
View listItem = myListAdapter.getView(size, null, list);
listItem.measure(0, 0);
totalHeight += listItem.getMeasuredHeight();
}
// Change Height of ListView
ViewGroup.LayoutParams params = list.getLayoutParams();
params.height = totalHeight
+ (list.getDividerHeight() * (shoutsList.size() - 1));
list.setLayoutParams(params);
}
The problem is that I request new data from server when the user scroll down, but when I update listview height it auto scroll and request data automatically

Textview text in multiline, Listview in Scrollview

I am using a listview in scrollview. I am able to show the list in listview in Scrollview using below method.
public static void setListViewHeightBasedOnChildren(ListView myListView) {
ListAdapter myListAdapter = myListView.getAdapter();
if (myListAdapter == null) {
// do nothing return null
return;
}
// set listAdapter in loop for getting final size
int totalHeight = 0;
for (int size = 0; size < myListAdapter.getCount(); size++) {
View listItem = myListAdapter.getView(size, null, myListView);
listItem.measure(0, 0);
totalHeight += listItem.getMeasuredHeight();
}
// setting listview item in adapter
ViewGroup.LayoutParams params = myListView.getLayoutParams();
params.height = totalHeight
+ (myListView.getDividerHeight() * (myListAdapter.getCount() - 1));
myListView.setLayoutParams(params);
// print height of adapter on log
Log.i("height of listItem:", String.valueOf(totalHeight));
}
There is a textview in listview and the textview's text is too long and it comes in 3 or 4 lines. In that case, the listview is not showing all items.

Stop scrolling at the end of gridview item

i put gridview inside scrollview using Helper class
public class Helper {
public static void getListViewSize(GridView myListView) {
ListAdapter myListAdapter = myListView.getAdapter();
if (myListAdapter == null) {
// do nothing return null
return;
}
// set listAdapter in loop for getting final size
int totalHeight = 0;
for (int size = 0; size < myListAdapter.getCount(); size++) {
View listItem = myListAdapter.getView(size, null, myListView);
listItem.measure(0, 0);
totalHeight += listItem.getMeasuredHeight();
}
// setting listview item in adapter
ViewGroup.LayoutParams params = myListView.getLayoutParams();
params.height = totalHeight
+ (myListView.getHeight() * (myListAdapter.getCount() - 1));
myListView.setLayoutParams(params);
// print height of adapter on log
Log.e("height of listItem:", String.valueOf(totalHeight));
}
}
And use this class as
adapter = new RSSReaderGridAdapter(context, mostLatestItems);
gridView.setAdapter(adapter);
Helper.getListViewSize(gridView);
It works fine..but when i scroll page scrolling not stops at last item of gridview...it keep scrolling..

Maybe the ScrollView is scrolled . If want to scroll GridView,you should override "onInterceptTouchEvent".

Focus on the first record of listview

I have a code for a listview inside a scrollview. The works ok. But when the app is started the focus is always placed in the first record of the listview.
my schema is:
radiobutton
Google maps
listview
if I do not put a scrollview the listview is very small
I put the code that does it:
public class Helper {
public static void getListViewSize(ListView myListView) {
ListAdapter myListAdapter = myListView.getAdapter();
if (myListAdapter == null) {
return;
}
//set listAdapter in loop for getting final size
int totalHeight = 0;
for (int size = 0; size < myListAdapter.getCount(); size++) {
View listItem = myListAdapter.getView(size, null, myListView);
listItem.measure(0, 0);
totalHeight += listItem.getMeasuredHeight();
}
//setting listview item in adapter
ViewGroup.LayoutParams params = myListView.getLayoutParams();
params.height = totalHeight + (myListView.getDividerHeight() * (myListAdapter.getCount() - 1));
myListView.setLayoutParams(params);
// print height of adapter on log
Log.i("height of listItem:", String.valueOf(totalHeight));
}
}

You can Override isEnabled(int position) method in your Adapter and return false so the focus will no longer in listview Item.
#Override
public boolean isEnabled(int position) {
return false;
}
