Android ListView inside ScrollView not proper

I am sorry, I am new to android xml part. I am setting my listview which is inside scroll view to full screen but its frame is still small. How to resolve it? I have already set both width and height to "match_parent". Can someone help?
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/activity_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.stacktips.speechtotext.MainActivity">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<ListView
android:id="#+id/list"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:listitem="#layout/row" >
</ListView>
</ScrollView>
<LinearLayout
android:id="#+id/btnSpeakContainer"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:background="#f5f5f5"
android:gravity="center_horizontal"
android:orientation="vertical"
android:padding="20dp">
<ImageButton
android:id="#+id/btnSpeak"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#null"
android:padding="16dp"
android:scaleType="fitCenter"
android:src="#mipmap/ic_microphone_2" />
<TextView
android:id="#+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/btnSpeak"
android:layout_margin="10dp"
android:text="#string/hint" />
</LinearLayout>
</RelativeLayout>

Putting the ListView inside a ScrollView means the ListView will not go to its full height. Take out the ScrollView surrounding the ListView and this should work for you :) ListView itself is scrollable.

I want scroll entire area, i don't want scroll on listview, when i put item in listview the area increases and i scroll entire area is possible?

Ok. Since your minimum SDK version is 16, you have 2 solution for your problem.
First is use this library:
https://github.com/PaoloRotolo/ExpandableHeightListView
This library makes you able to expand your ListViews to full height and then only your ScrollView will be scrollable.
Second solution is to use NestedScrollView instead of ScrollView and then use RecyclerView instead of ListView. Then you should only disable nestedScrolling for your RecyclerView.
Both solutions will give you your desire behavior.

You can use multiple type item for listview and simplified your layout to become like this
<?xml version="1.0" encoding="utf-8"?><?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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"
android:paddingBottom="#dimen/padBottom"
android:paddingLeft="#dimen/padLeft"
android:paddingRight="#dimen/padRight"
android:paddingTop="#dimen/padTop"
tools:context="com.example.fra87.eudroid.activity_class.Lista_Eventi"
>
<SearchView

android:layout_width="match_parent"
android:layout_height="50dp"
android:queryHint="Evento"
/>
<EditText
android:id="#+id/editText_nome_evento_composto"
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_below="#+id/cercaEvento"
android:hint="Nome Evento"
android:textSize="22dip"
/>
<View

android:layout_width="match_parent"
android:layout_height="5dp"
android:layout_below="#+id/editText_nome_evento_composto"
android:layout_marginBottom="10dp"
android:layout_marginTop="10dp"
android:background="#android:color/darker_gray"
/>
<ListView
android:id="#+id/listViewEventi"
android:layout_width="match_parent"

Relative Layout inside a ScrollView - Not scrolling

I have a relative layout as child of Scrollview. I already tried a bunch of answers in here but the scroll isn't working.
That's my xml file:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView 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:scrollbars="none"
android:fillViewport="true"
android:background="#drawable/home_bg_branco" >
<RelativeLayout
android:id="#+id/relative_categoria"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<ImageView
android:id="#+id/categoria_placeholder_slider_listview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="-3dp"
android:contentDescription="#string/home_placeholder_slider"
android:src="#drawable/home_placeholder_slider"
android:visibility="visible" />
<ImageSwitcher
android:id="#+id/home_imageswitcher_slider_listview"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_alignBottom="#id/categoria_placeholder_slider_listview"
android:layout_alignLeft="#id/categoria_placeholder_slider_listview"
android:layout_alignRight="#id/categoria_placeholder_slider_listview"
android:layout_alignTop="#id/categoria_placeholder_slider_listview"
android:scaleType="fitXY" />
<ListView
android:id="#+id/listViewCategoria"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/home_imageswitcher_slider_listview"
tools:ignore="NestedScrolling" >
</ListView>
<ImageView
android:id="#+id/categoria_cores_listview"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/categoria_placeholder_slider_listview"
android:layout_alignParentEnd="true"
android:layout_alignParentLeft="true"
android:contentDescription="#string/img_cores"
android:src="#drawable/img_cores" />
<ImageView
android:id="#+id/categoria_destaque_listview"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignStart="#id/categoria_placeholder_slider_listview"
android:contentDescription="#string/img_destaques"
android:src="#drawable/img_destaques" />
</RelativeLayout>
</ScrollView>
Another thing: i disabled the listview scroll to avoid conflicts.
Thanks in advance!

You should change layout_height of the RelativeLayout to match_parent:
<RelativeLayout
android:id="#+id/relative_categoria"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
Also remove android:fillViewport="true" from ScrollView.
In my project I have several ScrollViews exactly like this, and they work fine:
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
>
UPDATE
One last thing I can propose is to remove ListView from the ScrollView as it can interfere with layout and scrolling.

Add this line to your onCreate()
getActivity().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE|WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE);

Scroll PullToRefreshScrollview automatically in android

I have a Listview, FrameLayout inside PullToRefreshScrollview. And I'm loading a fragment into framelayout. Data is loading into listview using lazy adapter. I'm able to see the fragment/framelayout while listview is loading. But Scrollview is automatically scrolling to the postion of listview after data is loaded into listview and framelayout is not visible. How can I scroll the scrollview to top? Please help me. Thanks in advance
<?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="match_parent"
android:background="#color/app_bg"
android:orientation="vertical" >
<com.handmark.pulltorefresh.library.PullToRefreshScrollView
xmlns:ptr="http://schemas.android.com/apk/res-auto"
android:id="#+id/ptrScrollView"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_marginBottom="5dp"
android:layout_weight="1"
android:paddingBottom="5dp"

<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<FrameLayout
android:id="#+id/frame"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</FrameLayout>
<com.xxxx.yyyy.CustomListView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/listView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/app_bg"
android:focusable="false" />
<ProgressBar
android:id="#+id/spinner"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:visibility="gone" />
</LinearLayout>
</com.handmark.pulltorefresh.library.PullToRefreshScrollView>
</LinearLayout>

Here is the aproach I took
Lets say you have a reference to the PullToRefreshScrollView like so
PullToRefreshScrollView myRefreshScrollView = (PullToRefreshScrollView)findViewById(R.id. ptrScrollView);
To get the ACTUAL ScrollView object you need to call getRefreshableView() like so
ScrollView myScrollView = myRefreshScrollView.getRefreshableView();
and then scroll this object
myScrollView.scrollTo(0,0);
or
myScrollView.smoothScrollTo(0,0)

There are 2 teps to make it works:
you should set android:smoothScrollbar="true" in layout xml :
<com.handmark.pulltorefresh.library.PullToRefreshListView
android:id="#+id/news_list_listView_main"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#EEE"
android:cacheColorHint="#00000000"
android:divider="#00000000"
android:dividerHeight="5dp"
android:layout_marginTop="2dp"
android:paddingLeft="1dp"
android:paddingRight="1dp"
android:smoothScrollbar="true"/>
and Then,
myRefreshScrollView.getRefreshableView().smoothScrollToPosition(lastScollCount);

RelativeLayout content can not be seen

Like the following layout shows, when the items in list are too much, more than one screen.
I can not see the following LinearLayout content when I drag down.
How to solve this problem?
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ListView
android:id="#+id/list"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</ListView>
<LinearLayout
android:id="#+id/linearLayout1"
android:layout_width="wrap_content"
android:layout_height="100dp"
android:layout_below="#+id/list"
android:layout_centerHorizontal="true"
android:orientation="horizontal" >
<TextView
android:id="#+id/UserIDStatic"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/UserID" />
.
.
.
</LinearLayout>
</RelativeLayout>
Thanks in advance!

change to this
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ListView
android:id="#+id/list"
android:layout_width="match_parent"
android:layout_height="100dp" > <!-- use a definate dimension here -->
</ListView>
<LinearLayout
android:id="#+id/linearLayout1"
android:layout_width="wrap_content"
android:layout_height="100dp"
android:layout_below="#+id/list"
android:layout_centerHorizontal="true"
android:orientation="horizontal" >
<TextView
android:id="#+id/UserIDStatic"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/UserID" />
.
.
.
</LinearLayout>
</RelativeLayout>
or else put both ListView and LinearLayout in ScrollView
or as bellow comment
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:weightSum="1"
android:orientatio="verticle" >
<ListView
android:id="#+id/list"
android:layout_weight="0.5"
android:layout_width="match_parent"
android:layout_height="0dp" >
</ListView>
<LinearLayout
android:id="#+id/linearLayout1"
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight="0.5"
android:orientation="horizontal" >
<TextView
android:id="#+id/UserIDStatic"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/UserID" />
.
.
.
</LinearLayout>
</LinearLayout>

There are two options comes in picture.
Instead of Relative layout Use Vertical Linear layout with appropriate wieght to listview and inner linear layout (eg. 0.7 and 0.3)
Use same Relative layout as above with inner LinearLayout to alignparentbottom = true
and listview above="#innerLinearLayout" linearlayout.
This might solve your problem.
Using specific height for listview might cause different look in UI for different sized screens.
