can i have a listview and an expandablelistview in the same view

I have several edittexts in my view for taking input for a database query .I'm displaying the query results in a list view below the edittextfields. Because there are 7 edittextfields there is not enough space for the listview. I wanted to put all the edittexts in an expandablelistview.
Problem i'm facing is -only the expandablelistview item is shown -the listview doesnt come up at all --i have #android:id/empty and #android:id/list entries ---but nothing comes up
i can't add the listview into the expandablelistview as that is not allowed + since i need both #android:id/empty and #android:id/list to show query results i need a proper list view.
what are my options --? i could ofcourse display the results in a separate window

If you could show the xml you have right now it would be great but the ideas behind it needs to be something like:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<ExpandableListView
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<ListView
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
Edit:
Okay so i figured out that for this layout to function correctly you need to set dome weight so that the linearlayout understand what size to give each children. Use:
android:layout_weight="1"
in the listview and the expandablelistview (1 in both means thay will divide space between them)

Limit number of rows of listview

I am developing an application that needs to pair with other devices through Bluetooth. I was having trouble in order to show the list of paired devices in correct manner. I had also viewed the example in the android api (Bluetooth Chat), but i was having the same problem.
The list of paired devices are to big and then hides a search button that are at the bottom of the list.
My xml code is very the same of the example:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView android:id="#+id/listpaired_devices"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/title_paired_devices"
android:visibility="gone"
android:background="#666"
android:textColor="#fff"
android:paddingLeft="5dp"
/>
<ListView android:id="#+id/paired_devices"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:stackFromBottom="true"
android:layout_weight="1"
/>
<TextView android:id="#+id/list_new_devices"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/title_other_devices"
android:visibility="gone"
/>
<ListView android:id="#+id/new_devices"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:stackFromBottom="true"
android:layout_weight="2"
/>
<Button android:id="#+id/btscan"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/btscan"
/>
</LinearLayout>
But and i can't show the search button at the bottom.
Here my screen:
My Screen
You could see a bit of the button at the bottom of the dialog window.
It's possible to limit the number of rows shown at the listview ? Can anyone tell me how i can fix this problem

Firstly some points about your code:
layout_weight is only meaningful if an object has no size in a certain dimension, that is you set layout_height or layout_width to 0, so this has no effect on your code.
Setting the height of a ListView to wrap_content is pretty meaningless, and even if it works it's bad practice. Use either 'fill_parent' or a definite height.
The button is hidden because, as per the point above, the ListViews you have created have no predefined size so take up as much space as they can, pushing the button off the screen.
So let's think about what you really have there - it's just a single list with a button at the bottom (yes you may have headers or multiple sources of data in there but we'll get onto that).
The following layout will give you a ListView at the top and a Button at the bottom. The ListView will take up any space not being used by the Button. Notice how the Button is defined before the ListView in the layout - this causes Android to calculate how much height the button takes up before considering the ListView. It then gives the ListView the rest of the height available.
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<Button android:id="#+id/btscan"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:text="#string/btscan"
/>
<ListView android:id="#+id/all_devices"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_above="#id/btscan"
android:stackFromBottom="true"
/>
</RelativeLayout>
So that's the layout. Now lets consider the actual content of your list: you have a header, followed by a list of paired devices, followed by another header and then a list of new devices.
You can create this using a single Adapter - Commonsware provides a very good implementation called MergeAdapter but you could code your own. MergeAdapter doesn't directly let you a view (e.g. for the headers) but thankfully Commonsware also provides the SackOfViewsAdapter which allows you to add views to it, and then you can add the SackOfViewsAdapter to the MergeAdapter.
Here is some pseudo-code which should accomplish what is outlined above.
// This is the adapter we will use for our list with ListView.setAdapter
MergeAdapter listAdapter = new MergeAdapter();
// The first header - you'll need to inflate the actual View (myHeaderView1) from some resource
// using LayoutInflater
List<View> firstHeaderViews = new List<View();
firstHeaderViews.add(myHeaderView1);
SackOfViewsAdapter firstHeaderAdapter = new SackOfViewsAdapter(firstHeaderViews)
// Second header
List<View> secondHeaderViews = new List<View();
secondHeaderViews.add(myHeaderView2);
SackOfViewsAdapter secondHeaderAdapter = new SackOfViewsAdapter(secondHeaderViews);
// Now to add everything to the MergeAdapter
// First goes the first header
listAdapter.addAdapter(firstHeaderAdapter);
// Now your first list
listAdapter.addAdapter(firstListAdapter);
// Now your second header
listAdapter.addAdapter(secondHeaderAdapter);
// Now your second list
listAdapter.addAdapter(secondListAdapter);
// Now set the adapter to the list
myList.setAdapter(listAdapter)
The layout produced should look something like this. Note I extended the list to show how it behaves with a list longer than the screen; the button still remains visible. The red box marks the bounds of the screen.

You can limit the number of rows shown at the list view, but not sure if that will really help you in what you want to achieve, because you're hiding information from the user that might be important to him. You can limit the number of rows by limiting the number of items you pass to the listview adapter, or you can set the visibility to 'gone' in the getView method when the list view reaches a certain position (you can check the 'position' parameter of getView()).
However, I would suggest you use only one list view (add a separator for the 'new/other devices' title into the view for a list item, but hide it by default, and then, as already suggested by suri, use headers and footers for the listview (to place the scan button).

TextView and ListView in a LinearLayout

I searched for similar questions but didn't get the proper answer, so posting it as a new question.
Can a LinearLayout have two TextViews and one list view? I learn that listview can be used to display array elements only if the class extends ListActivity. The Class in my app extends Activity and uses listView.
I am trying to build an RSS Reader based on IBM tutorial. On running the project I am getting parsed text in both the Text views but ListView is not displaying. I can post the code and Logcat if required.

Linear Layout can have any number of children.
ListActivity is an Activity that Android have added for convenience when dealing with activities comprised of list.
You can use ListView on a regular Activity and just implement an adapter that will populate the list items with data from your model.
Android has some ready-made adapters that can be used for simple use-cases.
of course if you need a more complicated beahviour you can extend them.
Have a look on BaseAdapter, ArrayAdapter and CursorAdapter to get a better understanding of how to use adapters.

You can have a ListView in any activity, using a ListActivity just makes your life easier (usually). See here for details.

You can have a Linear layout with different views and list view inside for example:
?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="#drawable/background_new_search_activity_1">
<TextView
android:id="#+id/list_item_amount_text"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
<ListView
android:id="#android:id/list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:cacheColorHint="#00000000"/>
</LinearLayout>
And yes you can use the ListViewin all the activities, it is not necessary to extend ListActivity

Make sure the orientation of the ListView is set to vertical. Otherwise, it will try to display all items side by side, and those that fall outside the available view area won't be visible.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"> <!-- << orientation setting here -->

Android: what is the best way to show a TextView in case if no item in a ListView?

I need to show a list of items, the items are read from a database, and it is possible there is no item, in this case, I just want to show a TextView saying "there is no item", I think I could implement this by using relative layout, both list and text are in center of parent, they are displayed alternatively, but is there any way better than this?
Thanks!

Adding to Aleadam , Bill Mote
You may call at any time AdapterView.setEmptyView(View v) on an AdapterView object to attach a view you would like to use as the empty view.
The snippet is as follows:
empty = (TextView)findViewById(R.id.empty1);
list = (ListView)findViewById(R.id.list1);
list.setEmptyView(empty);
Make sure you keep the ListView and TextView inside the same parent.
For detailed description please refer this

If you're using a ListActivity, that is the default behavior. If not, then you can set the ListView visibility to GONE and a TextView visibility to VISIBLE.

Aleadam is right. Here's an example XML in support of his answer:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
<ListView
android:id="#+id/android:list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
<TextView
android:id="#id/android:empty"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:textColor="#drawable/red"
android:gravity="center_vertical|center_horizontal"
android:textStyle="bold"
android:text="#string/error_no_groups"
/>
</LinearLayout>

The first tutorial on the Android developer website explains how to do this:
http://developer.android.com/resources/tutorials/notepad/notepad-ex1.html
(Look under Step 4)
Snippet:
The ListView and TextView can be thought as two alternative views, only one of which will be displayed at once. ListView will be used when there are notes to be shown, while the TextView (which has a default value of "No Notes Yet!" defined as a string resource in res/values/strings.xml) will be displayed if there aren't any notes to display.
The View with the empty id is used automatically when the ListAdapter has no data for the ListView. The ListAdapter knows to look for this name by default. Alternatively, you could change the default empty view by using setEmptyView(View) on the ListView.

Clicking on the entire row of Android ListView

I have Created a ListView and set a background image.Everything goes fine except I am unable to click on the right side of the row of ListView.Can anybody help me this.
Below is the xml file...
<ListView
android:layout_width="wrap_content"
android:id="#+id/JSONListView"
android:layout_height="wrap_content"
android:background="#drawable/listbg"
android:focusable="false"
android:cacheColorHint="#00000000"
android:visibility="visible" >
</ListView>
And I am not using any View.

Use the attribute
android:layout_width="match_parent"
and set click listener for items.

I guess you have created your custom adapter. If so, just go to the getView() method of that custom adapter and on the holder instance of that portion of listitem add a onCLickListener.

Provide more info. XML layout, etc.
Im guessing there is a view there or it is not filling the entire width but difficult to say.
