Inner List in Android

I have a problem with lists.
I want to implement a scrollable big list, each element of which contains a text on the left side and a NON-scrollable inner list on the right side. (for example: the name of the flat and the list of its inhabitants names)
Both lists should be filled from the cursors and contain an informatio about them: I want to have an oppurtunitz to get all cursos fields when I click an element of the inner list.
As far as I understood I's not possible to solve it with two ListViews. ExpandableListView does not pass me because I do not want to expand the first list, I want to have the inner list always visible.
Do you have any ideas how can I realize it?

Try using a ListView for your big list, and an empty LinearLayout in each item. You fill the LinearLayout of each item programmatically in the big list adapters getView(..) method, where int position is the item number.
See also: android nested listview
Edit: Or use an ExpandableListView, which items you expand programmatically without animation with expandGroup(int position, boolean animate). Prevent collapsing by setting an ExpandableListView.OnGroupCollapseListener, in which you expand the group again. (seems a bit hacky)

Android create mosaic in row item adapter recyclerview

I want to create item adapter with a mosaic view include multiple images.
I found some libs: AndroidMosaicLayout,
QuiltViewLibrary.
But these show on the main view. In my case, I want to show images on the item adapter recyclerview.
It's same the row on facebook row new feed.
Any help, thanks.

You cam do it using the library AndroidMosaicLayout. In the layout used for the adapter of the RecyclerView just add the view of AndroidMosiacLayout and inside the recyclerview adapter, just inflate the layout resources and access the AndroidMosiacLayout normally by assigning the required layout pattern and data. At the end the AndroidMosiacLayout it is just a NestedScrollView, so you can use it the same way you use any other view or view group.

Alternate for a listview with single row

I have a ImageView with a TextView and Button. I have it currently in a custom list view, but I noticed now that I don't need to show more as one element (object). So I actually don't need a Listview to show the row (list entry). How can I show the list entry without a Listview?

You can put the elements of your custom listview item into a Layout, e.g. LinearLayout and simply add it to your activity's layout where you needed it.
You can set an OnClickListener for that layout, so user can click the whole thing.

I think you should use ListActivity. Then you can set up empty view for list. Here some tutorial: ListActivity and ListView Tips.
Also you can implement that logic with Recycler view by yourself or use library.
Here is solution from stackoverflow

Android listview with horizontal lines when empty

I have a Listview in my Android app, and I want there to be some horizontal lines when the list is empty to indicate to the user that this is a List. I know that there is the setEmptyView method on ListView, but I'm not sure what to put in that view if I want there to be list rows with horizontal lines. How would I accomplish this?

Having a bunch of horizontal lines for an empty list is an iOS convention. If you want your app to fit in with Android better you should set something else. Perhaps notify the user there was an error or that there are no items in the list. You can add this right to your layout.xml file if you're using a ListActivity. All you need to do is create a view and give it the id #android:id/empty.

put the listView in a FrameLayout and add another view in that Frame.
if you having any item in the list hide its (visiblity="gone") and show the other view.
OR
change your adapter to return multi ViewType
in your adapter if you have no item return other type of view

android set adapter to linear layout

I am trying to put a list view in a scroll view which is not possible as I found in several similar questions.
I have a quite large menu to be placed above list view, which completely hides the list view on small screens, so I need a scroll view which is not possible. I read that I should use a linear layout instead of list view to solve this problem. But not sure how to setup up an adapter on linearlayout. I am using a lazy adapter for image loading in the list view.
Code:
LinearLayout list=(LinearLayout)findViewById(R.id.listActivities);
adapter=new LazyAdapter(this, activityList);
list.setAdapter(adapter);

As I understand from your question there is a single view that you wonna put at the top of your list view. Try to use ListView.addHeaderView(View v) for that purpose. See android API documentation for more info.

You can add a view as header to the list view, which will solve your problem, it will place the view in the list view but on the top of list items.
listview.addHeaderView(yourview)

you can add HorizontalScrollView in your listview header where in HorizontalScrollView you can add linearlayout & horizontal menus in it
or
other option is to have one simple button in header of listview say action & clicking on that open new dialog with list of menus (actions) etc...
