Adjust Pan not working properly

Question

I am having an edittext in my app. I am using adjustPan to shift layout accordingly when keyboard opens. But when keyboard opens it does shift the layout but it still cuts the edittext and does not shift completely . I also tried adding layout to scrollview and adding padding bottom but it didn't helped. I also tried adjustResize but that also didn't worked. Here is the screen shot of both cases

Here is the manifest file(only this activity

<activity android:name=".activity.ActivityRegister"
        android:windowSoftInputMode="adjustResize|adjustPan"/>

And layout file

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/bg">
<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="wrap_content"
    android:paddingBottom="50dp"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.socialninjaz.doorstep.MainActivity"
