What is causing the ImageView resizing error?

Question

Android

I want to make the width and height of the ImageView change depending on the screen resolution (0.8 * display_width and display_height * 0.8), and I found this way for this, but when the application starts, it immediately dies, how to fix it?

<code lang="java">
ImageView spaceadventure = (ImageView)  findViewById(R.id.imageView);
        float density = getApplicationContext().getResources().getDisplayMetrics().density;
        spaceadventure.setLayoutParams(new AbsListView.LayoutParams((int) (density * 1), (int) (density * 1)));
