TextView cutting off content

I have a TextView within a ScrollView all wrapped in a LinearLayout and the end of the TextView is getting cutoff (multiple lines).
This is the XML:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:baselineAligned="false">
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/tv_description"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="8dp"
android:text=""
android:textSize="10dp"
android:layout_weight="1"
android:layout_gravity="fill_vertical" />
</ScrollView>
</LinearLayout>
The TextView is cutting off regardless of whether the pane scrolls or not and it's driving me mad! Any help?!

<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">//try this
if this doesnt solve the problem then:-
also you can try using ScrollView as a parent view.No need of that Linear layout if it just contains a single child(TextView)

Update. I 'fixed' the issue by changing the type of the fragment to work as a RecyclerFragment. Which when the fragment is added to the rest of the structure stops the cut-off!
I've inherited this app mid-development and the hand-over was...finish this app and fix the bugs, so I am finding my way through wearing a blindfold!
Thanks anyway!

Android not able to scroll up

I have a login layout with two EditText and a Button. When I'm typing some text in EditText, as the keyboard open it overlap the some of my layout. I try to scroll up but not able to scroll up layout to be visible. Ｉ'm using Relative Layout to create it. How to solve it?
Thank you.

Place your EditTexts and Button inside a ScrollView. Whatever is inside ScrollView can be scrolled. So your problem will be solved.
Note that ScrollView can host only one child. So you have to place all your Views inside a ViewGroup like LinearLayout or RelativeLayout
Although Julia Zhao's answer is correct, it uses RelativeLayout. If you use RelativeLayout you have to do more work to make your Views appear one below the other. So I suggest you to use LinearLayout with android:orientation="vertical" inside it. It will automatically place one View below the other without any extra effort. So you won't issues like one View overlapping on other.
<?xml version="1.0" encoding="utf-8"?>
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical">
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="UserName"/>
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:hint="Password"/>
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:text="Login"/>
</LinearLayout>
</ScrollView>

Try nesting everything in a ScrollView, hope this helps.
<?xml version="1.0" encoding="utf-8"?>
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
android:id="#id/RLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#000000"
xmlns:android="http://schemas.android.com/apk/res/android"
>
// Your code
</RelativeLayout>
</ScrollView>

Scroll View not work properly with padding

I have a problem in my Activity. The ScrollView doesn't scroll down to the bottom.
Here's my XML layout of the ScrollView:
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/test"
android:paddingRight="#dimen/layoutsPadding"
android:paddingTop="#dimen/layoutsPadding"
android:paddingLeft="#dimen/layoutsPadding"
android:paddingBottom="#dimen/scrollViewLayoutsPadding">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/tab_introduction_background"
android:orientation="vertical"
android:padding="#dimen/layoutsPadding">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/tab_introduction_title"
android:textSize="#dimen/bigFont"></TextView>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="#dimen/gap_titleAndText">
</LinearLayout>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/tab_introduction_description"
android:textSize="#dimen/smallFont"></TextView>
</LinearLayout>
</ScrollView>
What Can I do?

Since removing LinearLayout's padding worked, but you want it to have padding, why not just surround it with another LinearLayout and let only this outer LinearLayout to have a padding. And remove the inner LinearLayout's padding. This is probably not a very good style, but worth a try.
If you want to avoid this, you can also try removing the padding from the LinearLayout and adding a margin to all it's children.
EDIT: Since you really need that padding, adding an empty view at the bottom will definitely solve your problem, but it's not a good solution either:
<View
android:layout_width="fill_parent"
android:layout_height="30dp" />

ScrollView white space at bottom

I'm having an issue with ScrollView which leaves a blank space at the bottom. It is filled with few TextViews and GridViews and should fill the whole RelativeLayout parent.
<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="wrap_content"
tools:context=".showPictures">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView.../>
<GridView.../>
...
</LinearLayout>
</ScrollView>
</RelativeLayout>
Does anybody have an idea what's wrong?

Make your relative layout height match parent, also use android:fillViewPort = "true" in your scroll view
<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"
tools:context=".showPictures">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true">
//...

you can use this code to avoid extra padding on bottom of scroll view:
android:overScrollMode="never"

In my case I had a GridView inside a ScrollView that was causing this issue. It turns out the the layout_gravity in the GridLayout as 'center' was causing this issue.
'center_horizontal' makes more sense for a ScrollView anyway, but I added the ScrollView after the original layout was done (using 'center'), when I saw that the elements were going off-screen on some devices, hence the issue.
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<GridLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal" // having this as android:layout_gravity="center" causes extra space at bottom!
android:columnCount="2">
....

Give weight to every child in the scroll view including linear layout with value 1

Elements get hidden in ScrollView

I have the following:
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:id="#+id/layout_question_types"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="18sp"
android:layout_marginTop="18sp"
android:orientation="horizontal" >
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical" >
<!-- some content -->
</RelativeLayout>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginRight="18sp"
android:gravity="right"
android:orientation="vertical" >
<!-- some more content -->
</RelativeLayout>
</LinearLayout>
</ScrollView>
However, when I turn the phone horizontal to force the scrollbar, the scrollbar appears but the content at the bottom of the screen gets hidden.
Any ideas? There are similar questions on SO but they don't seem to fix the problem. Thanks.

Reason of this are margins and ScrollView parent FrameLayout which has some margin problems. Margins are ignored in measuring and scroll view measure its size without these margins and that is why the bottom part of inner views in ScrollView is not visible.
You can solve it simple wrapping child LinearLayout with another LinearLayout without margins.
