ScrollView not Working in my relativelayout

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.

Centering text within editText Android

I have a linearlayout with a textview, and edittext. How do I center the text within edittext. It appears to be drawn to the bottom as shown below.I want it to be consistent with the baseline similar to that of the textview to its left.
The layout code is as below:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="25dp"
android:layout_marginTop="20dp"
android:orientation="horizontal"
>
<TextView
android:layout_width="75dp"
android:layout_height="30dp"
android:ems="10"
android:textAlignment="center"
android:text="NAME"
android:textColor="#FFFFFF"
android:textSize="16sp"
android:singleLine="true"
android:id="#+id/tv_name"
android:background="#drawable/orange_left_rounded_corner"
/>
<EditText
android:layout_width="125dp"
android:layout_height="30dp"
android:ems="10"
android:layout_marginTop="10dp"
android:textAlignment="center"
android:text=""
android:layout_gravity="right"
android:gravity="center_horizontal"
android:textColor="#000000"
android:textSize="16sp"
android:singleLine="true"
android:id="#+id/et_name"
android:background="#drawable/orange_right_rounded_corner"
/>
</LinearLayout>

Use android:gravity="center" to have the input be centered

Just do that
<LinearLayout
android:layout_width="match_parent"
android:layout_height="25dp"
android:layout_marginTop="20dp"
android:orientation="horizontal"
>
<TextView
android:layout_width="75dp"
android:layout_height="30dp"
android:ems="10"
android:textAlignment="center"
android:text="NAME"
android:textColor="#FFFFFF"
android:textSize="16sp"
android:singleLine="true"
android:id="#+id/tv_name"
android:background="#drawable/orange_left_rounded_corner"
android:gravity="center_vertical"
/>
<EditText
android:layout_width="125dp"
android:layout_height="30dp"
android:ems="10"
android:layout_marginTop="10dp"
android:textAlignment="center"
android:text=""
android:layout_gravity="right"
android:gravity="center_horizontal"
android:textColor="#000000"
android:textSize="16sp"
android:singleLine="true"
android:id="#+id/et_name"
android:background="#drawable/orange_right_rounded_corner"
/>

Try with this code
<?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="wrap_content"
android:layout_marginTop="20dp"
android:gravity="center_vertical"
android:orientation="horizontal">
<TextView
android:id="#+id/tv_name"
android:layout_width="75dp"
android:layout_height="30dp"
android:background="#drawable/orange_left_rounded_corner"
android:ems="10"
android:gravity="center_vertical"
android:singleLine="true"
android:text="NAME"
android:textAlignment="center"
android:textColor="#FFFFFF"
android:textSize="16sp" />
<EditText
android:id="#+id/et_name"
android:layout_width="125dp"
android:layout_height="30dp"
android:layout_gravity="right"
android:layout_marginTop="10dp"
android:background="#drawable/orange_right_rounded_corner"
android:ems="10"
android:gravity="center_horizontal"
android:singleLine="true"
android:text=""
android:textAlignment="center"
android:textColor="#000000"
android:textSize="16sp" />

I have 5 horizontal linear layout is there. I aligned three edittext in a single linear layout. And I applied the weight field property 1 for all the editext. But in 1st and 3rd linear layout working perfectly with the property. Others are not working properly.

Then 4th line one addition linear layout available inside the horizontal layout, with one edittext and one imageview. It is also not fixing properly with weight property. I put layout code below.

If it won't work means, will the table layout give solution for this?
If I reduce the text inside the hint then also it was working fine in 2nd line. If I provide space for keeping same text length in with other edittext field which contains low text also not worked.

All your EditText should have:
android:layout_width="0dp"
And all LinearLayout should have:
android:weightsum="3"

Spaces are appearing on the right and left side of a Scroll View android?

I am developing an android application. On the preview the view is presanting the way I have set it but when I run it on a device I am seeing spaces on it right and left side.
Screen shots are attached for the better understanding of the problem.
Below is the code of my layout.

The problem (most probably) lies in the top level XML. I assume you posted only the content.xml which is included my activity_main.xml, because I can't see the Floating Action Button.
I guess you used the build-in generator to create layouts for you and edited the content.xml one. The paddings are defined inside the activity_main.xml one. Delete them and you are good to go.

Remove layout android:layout_margin="5dp" in Email Id EditText
<EditText
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:inputType="textEmailAddress"
android:ems="10"
android:id="#+id/emailIdEditText"
android:layout_gravity="center_vertical"
android:singleLine="true"
android:layout_weight="1"
android:background="#drawable/edittext"

I inserted long text in Edit Text view increase its size in Android

I am working on an Android application in which I am using edit text. When I put long text in it, it increase the size of the edit text. I having already given "wrap_content" on width and limit the number of lines and 'ems' but it won't work.
When I put long text or short text it increases or decreases the size of edit text. I have post the XML code and snapshot of my problem.
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:layout_weight="1"
android:orientation="vertical" >
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<TextView
android:id="#+id/fname"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text=" First Name:"
android:textColor="#color/Black"
android:textSize="12sp" />
<EditText
android:id="#+id/fnametxt"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#color/Beige"
android:enabled="false"
android:lines="1"
android:ems="15"
android:maxLines="1"
android:scrollHorizontally="true"
android:singleLine="true"
android:text="ufyufgiuhjlkh"
android:textColor="#color/Black"
android:textSize="12sp" />
</LinearLayout>

Just fix the width size of textview :
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<TextView
android:id="#+id/fname"
android:layout_width="100dp"
android:layout_height="wrap_content"
android:text=" First Name:"
android:textColor="#color/Black"
android:textSize="12sp" />
<EditText
android:id="#+id/fnametxt"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#color/Beige"
android:enabled="false"
android:lines="1"
android:ems="15"
android:maxLines="1"
android:scrollHorizontally="true"
android:singleLine="true"
android:text="ufyufgiuhjlkh"
android:textColor="#color/Black"
android:textSize="12sp" />
</LinearLayout>

Use Below Code it Works fine:
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:orientation="vertical" >
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<TextView
android:id="#+id/fname"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text=" First Name:"
android:textColor="#color/Black"
android:textSize="12sp"
android:singleLine="true"/>
<EditText
android:id="#+id/fnametxt"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#color/Beige"
android:enabled="false"
android:lines="1"
android:ems="15"
android:maxLines="1"
android:scrollHorizontally="true"
android:singleLine="true"
android:text="ufyufgiuhjlkh"
android:textColor="#color/Black"
android:textSize="12sp" />
</LinearLayout>

try this..
by giving width it makes design compatibility complex
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:layout_gravity="bottom"
android:orientation="vertical" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:weightSum="4" >
<TextView
android:id="#+id/fname"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:text=" First Name:"
android:textColor="#android:color/black"
android:textSize="12sp"
android:layout_weight="1" />
<EditText
android:id="#+id/fnametxt"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:background="#android:color/black"
android:layout_weight="3"
android:ems="15"
android:enabled="false"
android:lines="1"
android:maxLines="1"
android:scrollHorizontally="true"
android:singleLine="true"
android:text="ufyufgiuhjlkh"
android:textColor="#android:color/black"
android:textSize="12sp" />
</LinearLayout>
</LinearLayout>
