How to fix ListView inside ScrollView?

I need to put a ListView inside ScrollBar. I know there is other question about this theme but the answers are very complex and bad.
The ListView doesn't show all its elements, only the first one.
The main structure of my relevant code:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
....MORE ELEMENTS....
<ListView
android:layout_width="match_parent"
android:layout_height="wrap_content"
></ListView>
</LinearLayout>
</ScrollView>
</RelativeLayout>

Put your ListView in a separate LinearLayout parent or you can add it in a separate .xml file according to your choice and add
android:fillViewport="true"
in your scrollview, like this
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fillViewport="true">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<!....MORE ELEMENTS....>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<ListView
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</LinearLayout>
</LinearLayout>
</ScrollView>

Android: How to Display included layout and listview in one view together?

I would like to ask how can i display included layout and listview positioned under the included in onde view.
Layout:
<android.support.v4.widget.SwipeRefreshLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/swipeContainer"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".activity.TransactionsActivity">
<include
android:layout_width="fill_parent"
android:layout_height="10dp"
android:layout_alignParentTop="true"
layout="#layout/preloader" />
<ListView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/list"
/>
</android.support.v4.widget.SwipeRefreshLayout>
In the preview is displayed only the included layout, but lisview below is not displayed.
Many thanks for any advice.

Since SwipeRefreshLayout accept only one child. Wrap it inside LinearLayout or RelativeLayout.
<android.support.v4.widget.SwipeRefreshLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/swipeContainer"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".activity.TransactionsActivity">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<include
layout="#layout/preloader"
android:layout_width="fill_parent"
android:layout_height="10dp"
android:layout_alignParentTop="true" />
<ListView
android:id="#+id/list"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
Best Of Luck.

the RecyclerView I am injecting does not appear?

Here is my xml file:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:baselineAligned="false"

<!-- Framelayout to display Fragments -->
<FrameLayout

</LinearLayout>
<android.support.v7.widget.RecyclerView
android:id="#+id/RecyclerView"
android:layout_width="320dp"
android:layout_height="match_parent"
android:layout_gravity="left"
android:background="#ffffff"
android:scrollbars="vertical">
</android.support.v7.widget.RecyclerView>
</android.support.v4.widget.DrawerLayout>
</RelativeLayout>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1">
<android.support.v7.widget.RecyclerView
android:id="#+id/threadRecyclerView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scrollbars="vertical" />
</RelativeLayout>
</LinearLayout>
The main reason I did this design was to try to display the
<android.support.v7.widget.RecyclerView
android:id="#+id/threadRecyclerView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scrollbars="vertical" />
properly. However, when it is not being displayed at all. Before adding the two relativelayouts, I have one relative layout and the recyclerview did display, but it match_parent for every item of the list and was not able to fix it. How can I display my view properly?

The problem probably has to do with the layout_height="wrap_content" on your RecyclerView. You need to use setAutoMeasureEnabled(true) for wrap_content to work properly with a RecyclerView.
Here's an example:
RecyclerView threadRecyclerView = (RecyclerView)findViewById(R.id.threadRecyclerView);
threadRecyclerView.getLayoutManager().setAutoMeasureEnabled(true);
And your your XML should look something like this:
<android.support.v7.widget.RecyclerView
android:id="#+id/threadRecyclerView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:scrollbars="vertical"
app:layoutManager="LinearLayoutManager"/>
Hope that helps. :)
Note that setAutoMeasureEnabled only works properly for Android Support Library +23.2

How to get Toolbar to overlay sibling layout (z-ordering)

For the life of me, I cannot get this Toolbar to layout on top (note: not above, but on top of) its sibling LinearLayout. The only way I can get the Toolbar to overlay its sibling is by specifying the Toolbar's elevation to be > 0, but this doesn't work for pre-5.0.
I am using a parent FrameLayout, and the child Toolbar is located after its sibling LinearLayout in the XML. What am I missing? Even the Android Studio preview pane shows the Toolbar on top of the LinearLayout
<?xml version="1.0" encoding="utf-8"?>

</FrameLayout>

Turns out I had a fragment committing the linear layout over the main activity, which already contained it. Oops!

That's because of FrameLayout.
If you want to use FrameLayout, the views will not relate each other.
So all you need to do is ...
set "height of toolbar" to MarginTop of LinearLayout.
Hope, it will help.
