Can anyone help me to find out how to add an ImageView as a header to a ListView?
My code is here:
LayoutInflater inflater = (LayoutInflater) getApplicationContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View snapshot = inflater.inflate(R.layout.map_snapshot, null);
ListView channelsList = (ListView) findViewById(R.id.channelsList);
channelsList.addHeaderView(snapshot);
By now it shows nothing.
Try inflating your header view passing the parent (ListView) as parameter:
ListView channelsList = (ListView) findViewById(R.id.channelsList);
View snapshot = inflater.inflate(R.layout.map_snapshot, channelList, false);
Then, just add it to the ListView:
channelsList.addHeaderView(snapshot);
Try:
ListView channelsList = (ListView) findViewById(R.id.channelsList);
LayoutInflater inflater = getLayoutInflater();
ViewGroup header = (ViewGroup)inflater.inflate(R.layout.map_snapshot, channelsList , false);
channelsList .addHeaderView(header, null, false);
In layout map_snapshot,you must be having parent layout as here i have taken Linear Layout likewise take that.
ListView channelsList = (ListView) findViewById(R.id.channelsList);
LinearLayout headerView = (LinearLayout) getLayoutInflater().inflate(R.layout.map_snapshot, null);
listView.addHeaderView(headerView);
if you want to add views in layout:
TextView mUsername=(TextView) headerView.findViewById(R.id.user_name);
You can use CommonsWare MergeAdapter or SectionedListAdapter. With this library you can use any View as Header in your Listview. See this SO question and accepted answer for more information.

I want to add textview dynamically for which I have added the below code.But I am do not see any textview on my activity. I cant add a listview as I am already using recycleview . Any one any error ?
{
LayoutInflater layoutInflater = (LayoutInflater) getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
LinearLayout review_layout = (LinearLayout) rootMovieView.findViewById(R.id.review_comment);
for (ReviewsResult comment : review.getReviewsResults()) {
View view = layoutInflater.inflate(R.layout.layout_movie_comments, review_layout, false);
TextView tvCommentBy = (TextView) view.findViewById(R.id.tv_comment_by);
TextView tvCommentContent = (TextView) view.findViewById(R.id.tv_comment_content);
tvCommentContent.setText(comment.getContent());
tvCommentBy.setText(comment.getAuthor());
review_layout.addView(view);
}
}
You can also try something like this
View myLay; // view that contains you textView
LinearLayout rootlay; //root view in which you want to add
myLay = LayoutInflater.from(this).inflate(R.layout.layout_movie_comments,
null);
TextView tvCommentBy = (TextView) view.findViewById(R.id.tv_comment_by);
TextView tvCommentContent = (TextView) myLay.findViewById(R.id.tv_comment_content);
tvCommentContent.setText(comment.getContent());
tvCommentBy.setText(comment.getAuthor());
rootlay.addView(myLay);
Hope this helps :)
Do below two changes and check weather it is working or not, as nothing else seems to wrong in code.
LayoutInflater inflater = getActivity().getLayoutInflater();
View view = layoutInflater.inflate(R.layout.layout_movie_comments, null);
rootMoviewView is not the rootView it was a recylceView in a rootView .This way the textview is generated in rootView not in recylceView.
I have a listview with an adapter. I want to add a footer and that this footer will be displayed when scrolling the listview. Right now with this code the footerview is displayed when the listview is finished. In the onCreate method of the list i have:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_listado_imagenes_subidas_main);
// load list application
listImagenes = (ListView)findViewById(R.id.lvImages);
LayoutInflater inflater = getLayoutInflater();
ViewGroup footer = (ViewGroup) inflater.inflate(R.layout.footer3buttons, listImagenes,
false);
listImagenes.addFooterView(footer, null, false);
// create new adapter
ImagenesAdapter adapter = new ImagenesAdapter(this, ListadoImagenes());
// set adapter to list view
listImagenes.setAdapter(adapter);
}
Could you please help me with this issue?
Thank you in advanced.
If i understood correctly what you wan't is a "sticky" footer the addFooterView method add a footer after the last view item, for a sticky footer you have to roll your own, or use an external library for it.
try with this one
View footerView = ((LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.footer_layout, null, false);
list.addFooterView(footerView);
I have a View extending google MapView. And a ListView with items. What I need is to put MyMapView as a header to the list view. Help please what to do
Update: When I try to do this:
LayoutInflater inflater = (LayoutInflater)getApplicationContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
ListView list = (ListView) findViewById(R.id.list);
View m = inflater.inflate(R.layout.map, list, false);
list.addHeaderView(m);
I got an error:
MapViews can only be created inside an instances of MapActivity
I think it's because I have removed my xml layout for map into different.xml from my activity
Try this
Create your ListViewHeader.xml first
and do this
ListView lv = getListView(); // Your listView
LayoutInflater inflater = getLayoutInflater();
ViewGroup header = (ViewGroup)inflater.inflate(R.layout.YourHeader, lv, false);
lv.addHeaderView(header, null, false);
take a look on Android: Adding static header to the top of a ListActivity
Try to call
ListView.addHeaderView (View v)
before you set adapter to this ListView
if you are using a custom adapter, in getView() method provide different view at position 0.
if(position==0)
{
//Provide header view
}
else
{
//provide normal row
}
You can do the following to add a view as ListView header in android.
ListView list = (ListView) findViewById(R.id.list);
LayoutInflater inflater = getLayoutInflater();
ViewGroup viewGroup= (ViewGroup)inflater.inflate(R.layout.YourLayoutFile,list, false);
list.addHeaderView(viewGroup, null, false);
I have a requirement that I need to add header to my list view .
Below is my code for achieve the same..
ListView listView;
listView = (ListView) findViewById(R.id.list_view);
//View header = View.inflate(this , R.layout.header, null);
LayoutInflater ll = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View v2 = ll.inflate(R.layout.header, null, false);
listView.addHeaderView(v2);
But "listView.addHeaderView(v2)" this line giving "NullPointerException"
Please let me know what can be done to resolve this issue.
just try this:
listView.addHeaderView(LayoutInflater.from(this).inflate(R.layout.header, null));
instead of :
LayoutInflater ll = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View v2 = ll.inflate(R.layout.header, null, false);
listView.addHeaderView(v2);
I'm reusing the ListView AND the LayoutInflater here for both a header and a footer:
ListView lv = getListView();
LayoutInflater inflater = getLayoutInflater();
View header = (View)inflater.inflate(R.layout.header, lv, false);
lv.addHeaderView(header, null, false);
View footer = (View)inflater.inflate(R.layout.footer, lv, false);
lv.addFooterView(footer, null, false);
I reckon reusing the ListView is perfectly sensible, but I'm not so sure about the LayoutInflater. Am I flirting with disaster here, or is this okay?
Please refer to : http://developer.android.com/reference/android/widget/ListView.html#getFooterViewsCount()
Returns the number of footer views in the list. Footer views are
special views at the bottom of the list that should not be recycled
during a layout.
So yeah... I don't think you are doing anything wrong.
