improper display of an app on nexus 5 marshmallow devices

Question

i got a very weird type of problem while developing a basic android app. While I've created an app in which the background image of an app is visible to all the devices except nexus devices of android marshmallow. Kindly help me in solving the error. Below is the code and screenshot attached.

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

            android:hint="@string/password"
            android:inputType="textPassword"
            android:textColorHint="#FFF8E5" />

        <Button

    </LinearLayout>


</RelativeLayout>

You are enforcing an image to a relative layout background. The system might not work properly. Why don't you try ImageView and decode Bitmap. — Keshav, Jan 10 '16 at 18:50

Please try to use an ImageView and set it as background.

It means:

Use a RelativeLayout or a FrameLayout and define your ImageView as the first child. The first objects defined are the lowest in the z-order (i.e. they will be "below" the other views).

From: Setting an ImageView to the background Android

To fit it to whole screen device use match_parent or android:scaleType="fitXY"

Your code should look like this:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:background="#000000" >

<ImageView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_alignParentTop="true"
    android:layout_centerHorizontal="true"
    android:layout_marginTop="42dp"
    tools:ignore="ContentDescription" />

//Rest of widgets......
