Android可绘制对象的大小无法缩放

Question

Alright, this seems like it can be a very confusing question but I'm going to try anyway.

I am developing an application right now, and the only thing that you should know is that there are two drawables in this application.

Both drawables have the same exact width. There is a background drawable that obviously goes in the background of the XML. And then theres an ImageView of a simple line. This line is a drawable aswell.

On some devices/emulators, the line is not the full width of its resolution. Despite the fact that both drawables have the same exact width. And both are viewed in the same portrait mode.

Is there any fix to this? Basically this line moves upwards and represents something important, but I can't have it be a different size than the background. I really don't fully understand why the background with a width of 600, and a line with a width of 600 isn't the same size on some devices. Despite putting both drawables in the Drawable folder, and not one for the different resolutions. I currently do not have any screenshots, I will make some if need be, but I hope someone knows why this problem is bugging me and if I am doing something wrong. Can I perhaps tell the application that its resolution must be 800x600, so that all devices that are capable of showing that many pixels, will do so? If this is possible, how do I do this? I hope someone is able to help a newbie out :)

XML:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/root"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/background"
    android:gravity="top"
    android:orientation="vertical" >

    <ImageView
        android:id="@+id/imageView1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="-60dp"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true"
        android:layout_gravity="center_horizontal"
        android:src="@drawable/line" />  

</RelativeLayout>

尝试将imageview的scaleType设置为fitXY。

    android:scaleType="fitXY"
