I am try to get image from my server using bitmap . It's work fine, image hight resolution, but i see it in the middle of my imageView. Image view has full container width. There code of layout:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ImageView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/background"
        android:layout_alignParentTop="true"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:background="@drawable/android_bg" />

    <ImageButton
        android:layout_width="160dp"
        android:layout_height="40dp"
        android:id="@+id/imageButton"
        android:layout_centerVertical="true"
        android:layout_centerHorizontal="true"
        android:background="@drawable/login_button"
        />

    <ImageButton
        android:layout_width="160dp"
        android:layout_height="40dp"
        android:id="@+id/imageButton2"
        android:layout_marginTop="44dp"
        android:background="@drawable/registration_button"
        android:layout_below="@+id/imageButton"
        android:layout_alignLeft="@+id/imageButton"
        android:layout_alignStart="@+id/imageButton" />

    <TextView
        android:layout_width="160dp"
        android:layout_height="wrap_content"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:text="Bentornato"
        android:id="@+id/textView2"
        android:gravity="center"
        android:layout_above="@+id/imageButton"
        android:layout_alignLeft="@+id/imageButton"
        android:layout_alignStart="@+id/imageButton"
        android:layout_marginBottom="42dp" />

    <ImageView
        android:layout_width="match_parent"
        android:layout_height="125dp"
        android:id="@+id/home_logo"


        />
</RelativeLayout>

So my imageView has id home_logo and has width match_parent. What can i do wrong?

您也可以通过将图像设置为imageview背景来做到这一点

     imageview.setBackgroundResource(R.drawable.your_image);
