Android background image - imageview

I have one activity, and I set imageview element to match parent with one of my background image with dimensions: 1440x2560 . I need to make this image on fullscrean. But whenever I put that image using scaleType="fitXY" I get this: enter image description here

XML layout:

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.backgroundApp.SecondActivity">

    <ImageView
        android:id="@+id/imageView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:srcCompat="@drawable/background"
        android:scaleType="fitXY"/>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">


        <TextView
            android:id="@+id/textView"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="TextView"/>

    </LinearLayout>

</android.support.v4.widget.DrawerLayout>

Activity:

package com.backgroundApp;

import android.graphics.Color;
import android.graphics.drawable.ColorDrawable;
import android.support.v7.app.ActionBar;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

public class SecondActivity extends AppCompatActivity {

    ActionBar actionBar;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_second);

        actionBar = getSupportActionBar();
        actionBar.setBackgroundDrawable(new ColorDrawable(Color.parseColor("#004d40")));
    }
}

use setAdjustViewBounds

setAdjustViewBounds(boolean adjustViewBounds)

Set this to true if you want the ImageView to adjust its bounds to preserve the aspect ratio of its drawable. 

<ImageView
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:adjustViewBounds="true"
    android:scaleType="fitXY"/>

or try to set programatically

 imageView.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT));
 imageView.setScaleType(ImageView.ScaleType.FIT_XY);
 imageView.setAdjustViewBounds(true);

Use adjustViewBounds=true property in ImageView tag like

 <ImageView
    android:id="@+id/imageView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:srcCompat="@drawable/background"
    android:adjustViewBounds="true"
    android:scaleType="fitXY"/>
