                android:inputType="textPassword" />
        </LinearLayout>

        <LinearLayout
            android:orientation="horizontal"
            android:layout_width="match_parent"
            android:layout_height="wrap_content">

            <TextView
                android:id="@+id/lblRetypePassword"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="@string/RetypePassword"
                android:textAppearance="?android:attr/textAppearanceMedium" />

            <EditText
                android:id="@+id/txtRetypePassword"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:ems="10"
                android:inputType="textPassword" />
        </LinearLayout>

        <Button
            android:id="@+id/btnChangePassword"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:onClick="changePassword"
            android:text="Change Password" />

        <ListView
            android:id="@+id/lstUsers"
            android:layout_width="340dp"
            android:layout_height="wrap_content" />
    </LinearLayout>
</ScrollView>

And Here's the expecting output:

The expected output is : I have some items in lstUsers and there wouldn't be enough space for displaying all the users, so I would like to add a scrollview to the Layout to let users scroll down.

But the problem is: the scrollview doesn't wrap any controls at all, the outcome is:

As you can see, the scrollview is unable to wrap the lstUser

Is there anything wrong with the layout file?

Yes, the whole layout is not scrolling – User2012384 Dec 14 '15 at 05:23 — User2012384, Dec 14 '15 at 05:23

I don't think you are allowed to put a listview in a scrollview. Listview implements its own scroller so it doesn't like being in a scrollview. Take a look at this link

How can I put a ListView into a ScrollView without it collapsing?

Scrollview and Listview do not work well with each other.

What I would suggest u is to make 'lstUsers' Listview the main content of the layout file.

Create a separate layout file with the views that are above the listview.

Then inflate this layout file and add it as a header view to the listview.
