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

Question

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.

<LinearLayout
    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="------"
    >

Answer 1

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.

Answer 2

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"
  android:paddingLeft="4dp" />
