ScrollView not Working in my relativelayout - android

I followed someone example on having a relative layout with a scrollview. I did exactly it and my page still won't scroll. Am I missing out something? Or must I change it to a linear layout to make it work? Still new to Android Studio here.
Any help will be much appreciated. Randomly adding words so I can post this.

We can able to scroll the view only when the items in the scroll view exits the visibility. I check your code it happens for your layout too. For checking add few more item in that scroll view, It will start scroll
And one more thing instead of setting some constant value set android:layout_height="wrap_content"


This should work:
<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="mapp.com.sg.receiptscanner.Info">
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content">


always use this
android:layout_width="match_parent"
android:layout_height="wrap_content"
for scrollview and its only child.

Adjusting Widgets in a Layout

Hey I have a ScrollView which allow users to input their credentials in the EditTexts inside. But there's one problem, one of the TextViews prior to its EditText consist of a Spinner but I do not know how to make that Spinner and the TextView side by side. Any help will be appreciated, thanks!:)

Try this,
<?xml version="1.0" encoding="utf-8"?>

Use Linear Layout after Edittext3 as:

Can someone help me ? I am wondering if it's even possible to have only a part of the screen scrollable

Try this approach:
Step 1
Use a LinearLayout as your root element to enable you to use layout_weightattribute;
Step 2
Inside your layout, you can split it into 3 parts each with a layout_weight of .3
For example:
<LinearLayout
...
orientation="vertical"
... >
<LinearLayout
layout_weight=".3"
layout_width="match_parent"
layout_height="0dp" />
<ScrollView
layout_weight=".3"
layout_width="match_parent"
layout_height="0dp" />
<LinearLayout
layout_weight=".3"
layout_width="match_parent"
layout_height="0dp" />
</LinearLayout> !-- end of root layout here
I said .3 just in case you want to have the sections occupy the same size of the window; but you can set them to whatever you want according to your needs.
I hope this helps.
Note A ScrollView only accepts ONE child element!
Good luck!

Could anyone help me find the reason as to why this won't scroll? Inside the relative layout I have textViews, spinners and editTexts. I'm pretty new to android and xml so I have no idea why it's not scrolling.
Edit: here is the full layout as requested.

Based on your code you don't need the parent linear layout. Try to delete it and use the scrollView as parent. And also remove the orientation and scrollbars attributes to the relativeLayout, you don't need them.

Android SDK: RelativeLayout - Button WILL NOT center horizontally, even with Layout_CenterHorizontal=true

I really hope somebody can help me here because I am going to start pulling my hair out if this keeps doing what it's doing.
I'm trying to design a layout and I want all of my stuff to be centered. So far, everything is. However, the Save button I created will not center itself for the life of it. It consistently aligns its left edge with the center of the screen, rather than the center of the button itself.
Below is a screenshot of my simple design and the xml behind it... Any help will be GREATLY appreciated!

And when I tried to add the following after defining RelativeLayout and before closing RelativeLayout, it broke the app immediately when I run it.
<ScrollView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
...........
</ScrollView>
How can I make it scrollable?

Your app crashes because ScrollView can host only one direct child.
Direct from official documentation:
Layout container for a view hierarchy that can be scrolled by the
user, allowing it to be larger than the physical display. A ScrollView
is a FrameLayout, meaning you should place one child in it containing
the entire contents to scroll; this child may itself be a layout
manager with a complex hierarchy of objects. A child that is often
used is a LinearLayout in a vertical orientation, presenting a
vertical array of top-level items that the user can scroll through.
Look this http://developer.android.com/reference/android/widget/ScrollView.html.
To solve your xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

Hope help you

I think you must enclose your relative layout in your scrollview ( before defining and after closing ) .
EDIT : You must also enclose your relative layout in Liner Layout
ex :
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/scroll"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
android:stackFromBottom="true"
android:transcriptMode="alwaysScroll" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/background"
android:paddingBottom="16dp"
android:paddingLeft="16dp"
android:paddingRight="16dp"
android:paddingTop="16dp"
android:textDirection="anyRtl"
tools:context=".AddDiscountActivity" >
</RelativeLayout>
</LinearLayout>
</SrcollView>
