Show all Items in ListView in Android

I have started building an app with two ListView's under each other.
Now i put an ScrollView over it, because the amout of itmes might get very big and therefore i want the whole layout to be scrollable and not the lists itself. But my solution dosent work!
btw: i dont want to replace my ListViews with a LinearLayout or so because then all my adapters are gone.
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
style="#style/Heading"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="ListView1" />
<Space
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1" />
<Button
style="#style/ButtonStyle.SpinnerAddButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:drawableRight="#drawable/ic_add_black_24dp"
android:onClick="addToList1" />
</LinearLayout>
<ListView
android:id="#+id/listView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="#dimen/marginLeft"
android:layout_marginRight="#dimen/marginLeft" />
<!--Second list-->
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
style="#style/Heading"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="ListView2" />
<Space
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1" />
<Button
style="#style/ButtonStyle.SpinnerAddButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:drawableRight="#drawable/ic_add_black_24dp"
android:onClick="addToList2" />
</LinearLayout>
<ListView
android:id="#+id/listView2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="#dimen/marginLeft"
android:layout_marginRight="#dimen/marginLeft" />
</LinearLayout>
</ScrollView>
My Layout now shows all the ListViews under each other but only one Item per ListView and you can then scroll through this Lists.

You should should use one listview and just have different viewtypes.
#Override
public int getItemViewType(int position) {
return isFirstItem(position) ? TYPE_ITEMA : TYPE_ITEMB;
}
#Override
public int getViewTypeCount() {
return 2;
}

Textview at the bottom of listview does not appear as listview adds more items?

In my first screen shot you can see expended listview at top and textview placed at below next to expended listview.
But if you look at my second screen shot, as the listview adds more items textview place at the bottom does not appear.
My layout code is :
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="#+id/form_view"
>
<LinearLayout
android:id="#+id/relativeLayout1"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<Spinner
android:layout_height="wrap_content"
android:layout_width="0dip"
android:layout_weight="2"
android:id="#+id/spinnerSemester" />
<Button
android:id="#+id/graph_button"
android:layout_width="0dip"
android:layout_weight="0.7"
android:layout_height="wrap_content"
android:text="Chart" />
</LinearLayout>
<ExpandableListView
android:id="#+id/lv_attendance"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_weight="1"
android:cacheColorHint="#00000000"
>
</ExpandableListView>
<TextView
android:id="#+id/TV_note"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/lv_attendance"
android:paddingLeft="10dp"
android:text="[NOTE : The data displayed here is for advance information only. Please check with the college office/department concerned for the final and certified data. In case of discrepancies, the data maintained in the college records will be deemed to be the final one.]"
android:layout_marginTop="10px"
android:textSize="13sp" />
</LinearLayout>
Thanks,

Try as below...
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/form_view"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<LinearLayout
android:id="#+id/relativeLayout1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<Spinner
android:id="#+id/spinnerSemester"
android:layout_width="0dip"
android:layout_height="wrap_content"
android:layout_weight="2" />
<Button
android:id="#+id/graph_button"
android:layout_width="0dip"
android:layout_height="wrap_content"
android:layout_weight="0.7"
android:text="Chart" />
</LinearLayout>
<ExpandableListView
android:id="#+id/lv_attendance"
android:layout_width="match_parent"
android:layout_height="0dip"
android:layout_weight="1"
android:cacheColorHint="#00000000" >
</ExpandableListView>
<TextView
android:id="#+id/TV_note"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="10dip"
android:paddingLeft="10dp"
android:text="[NOTE : The data displayed here is for advance information only. Please check with the college office/department concerned for the final and certified data. In case of discrepancies, the data maintained in the college records will be deemed to be the final one.]"
android:textSize="13sp" />
</LinearLayout>

consider specifyig android:layout_weight to the views, also encasing that text view in a framelayout or linearlayout
Gods, I hate layout...

Dont use android:layout_below="#+id/lv_attendance", its creating problem, use alignParentBottom instead.

Android, LinearLayout won't scroll

I am relatively new to android programing. Can anybody tell me why my ScrollView won't scroll?
My activity has implemented OnGestureListener for getting some touch information. But, I tried to disable onGestureListener and it still won't work.
It works outside of the SlidingDrawer. Is it possible to get it work inside of the SlidingDrawer?
I solved it by giving to ScrollView ID and then put that ID in SlidingDrawer android:content="#+id/content".
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

give some value to scrollView's width and height and try like this
<ScrollView
android:id="#id/content"
android:layout_width="300dp"
android:layout_height="300dp"
android:layout_centerHorizontal="true"
android:layout_marginTop="15dp">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
</LinearLayout>
</ScrollView>
please change scrollview id like this:
android:id="#id/content"
please change handle button id like this:
android:id="#id/handle"

The containers (hierarchical parents) of the ScrollView have the following attribute set this way: android:layout_height="match_parent", which forces them to limit their content to the height of the activity (screen).
For your ScrollView to work, try to get the ScrollView to a higher hierarchical level, so that won't be constrained by its parent.

Last two items of a fragments Listview not showing when a footer is present

Good day, I have an Activity which contains 4 fragments. The Activity has a footer which I use to switch between these fragment views. Now in one of my fragments, i have some widgets and the last widget is a ListView. The trouble am having is, the last 2 entries in the Listview are not displaying correctly! they are obscured by the footer. I have set my LayoutParameters for both the width and height of the Listview to FILL_PARENT. but its not working. Any idea how i can solve this? Thanks in advance.
My Layout is :
for the fragment:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"

<ListView
android:id="#android:id/list"
android:layout_width="fill_parent"

</RelativeLayout>
and for the Activity i have this:
<
?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<FrameLayout
android:id="#+id/fragment_container_id"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</FrameLayout>
<include layout="#layout/footer"></include>"
</RelativeLayout>
i replace the fragments with in the framelayout of the Activity

What Layout are you using in your Fragment, this surely won't happen if you use RelativeLayout and set above attribute to your ListView like this :
Try to add this into FrameLayout in your Activity layout.
android:layout_above="#+id/footer"

List is taking too much space and EditText with buttons can't be viewed

I want to have a ListView, followed by a EdiText, folowed by 2 buttons like:
ListView <NEWLINE>
EditText <NEWLINE>
Button1 Button2 <NEWLINE>
I have the code and if the list is small everything goes well. However, if the list has many elements it will take all the space and I won't be able to see the EditText or the buttons.
I have trimmed it down to the part where the problem starts:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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/in"
android:layout_below="#id/button_contacts"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:stackFromBottom="true"
android:transcriptMode="alwaysScroll"
android:layout_weight="1.0"
/>
<EditText
android:id="#+id/entry"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#android:drawable/editbox_background"
android:layout_below="#id/in" />
<Button
android:id="#+id/Convert"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_below="#id/entry"
android:layout_alignParentRight="true"
android:layout_marginLeft="10dip"
android:text="Convert" />
<Button
android:id="#+id/sendSMS"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_toLeftOf="#id/Convert"
android:layout_alignTop="#id/Convert"
android:text="Send" />
</RelativeLayout>
How can I solve this?

the below code works for me and i hope it will work for you too...
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
style="#style/MainLinearLayout">"
<TableLayout android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
style="#style/MainTableLayoutStyle">
<ListView android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#android:id/list"
android:layout_weight="1"
android:cacheColorHint="#color/transparent"
>
</ListView>
<TableRow>
<EditText
android:id="#+id/entry"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#android:drawable/editbox_background"
android:layout_below="#id/in" />
</TableRow>
<TableRow >
<Button android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/button1"
android:text="button1"
android:layout_gravity="left"
android:layout_weight="1"
/>
<Button android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/button1"
android:text="button2"
android:layout_gravity="right"
android:layout_weight="1"
/>
</TableRow>
</TableLayout>
</LinearLayout>

Because in ListView you use android:layout_weight="1.0" so, it took all space. you should add 1 layout to wrap your Text,Buttom etc. and add this android:layout_weight="2.0" or 3.0 (it's up to you) Try.
P.S. If it still not work For Try change all android:layout_height="fill_parent" To android:layout_height="wrap_content"
<ListView android:id="#+id/in"
android:layout_below="#id/button_contacts"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:stackFromBottom="true"
android:transcriptMode="alwaysScroll"
android:layout_weight="1.0"
/>
<Relativelaout
android:id="#+id/bottomcontrol"
android:layout_below="#id/in"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="2.0">
<EditText
android:id="#+id/entry"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#android:drawable/editbox_background"
/>
<Button
android:id="#+id/Convert"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_below="#id/entry"
android:layout_alignParentRight="true"
android:layout_marginLeft="10dip"
android:text="Convert" />
<Button
android:id="#+id/sendSMS"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_toLeftOf="#id/Convert"
android:layout_alignTop="#id/Convert"
android:text="Send" />
</RelativeLayout>

You need to give your listview a fixed height.
<ListView android:id="#+id/in"
android:layout_below="#id/button_contacts"
android:layout_width="fill_parent"
android:layout_height="100dp"
android:stackFromBottom="true"
android:transcriptMode="alwaysScroll"
android:layout_weight="1.0"
/>
Another choice is to set the height programmatically in the code. If you do this you need to do in the Activity's onWindowFocused() method. You can then programmatically set it to say half your screen.
Private LinearLayout llfullscreen;//llfullscreen is the viewgroup
//that stretches the whole screen
Private ListView lv;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
llfullscreen = findViewById(R.id.bottomcontrol)
}
#Override
public void onWindowFocusChanged(boolean hasFocus) {
super.onWindowFocusChanged(hasFocus);
if(hasFocus && llfullscreen!=null){
int layoutHeight = llfullscreen.getHeight();
ViewGroup.LayoutParams params = lv.getLayoutParams();
params.height = lv/2; //Set to half the screens size
this.lv.setLayoutParams(params);
this.lv.invalidate();
}
}
