ImageView fills parent's width OR height, but maintains aspect ratio

Question

I have a square image (though this problem also applies to rectangular images). I want to display the image as large as possible, stretching them if necessary, to fill thei

Did you try to adjust it programmaticaly? I think it works really well if you calculate the height of your TextViews and adjust the height and width of the image based on this.

private void adjustImageView()
{
    //Get the display dimensions
    DisplayMetrics metrics = new DisplayMetrics();
    getWindowManager().getDefaultDisplay().getMetrics(metrics);

    //TextView name
    TextView name = (TextView) findViewById(R.id.name);
    name.setText("your name text goes here");
    name.measure(0, 0);

    //name TextView height
    int nameH = name.getMeasuredHeight();

    //TextView name2
    TextView name2 = (TextView) findViewById(R.id.name2);
    name2.setText("your name2 text goes here");
    name2.measure(0, 0);

    //name2 TextView height
    int name2H = name2.getMeasuredHeight();

    //Original image
    Bitmap imageOriginal = BitmapFactory.decodeResource(getResources(), R.drawable.image);

    //Width/Height ratio of your image
    float imageOriginalWidthHeightRatio = (float) imageOriginal.getWidth() / (float) imageOriginal.getHeight();

    //Calculate the new width and height of the image to display 
    int imageToShowHeight = metrics.heightPixels - nameH - name2H;
    int imageToShowWidth = (int) (imageOriginalWidthHeightRatio * imageToShowHeight);

    //Adjust the image width and height if bigger than screen
    if(imageToShowWidth > metrics.widthPixels)
    {
        imageToShowWidth = metrics.widthPixels;
        imageToShowHeight = (int) (imageToShowWidth / imageOriginalWidthHeightRatio);
    }

    //Create the new image to be shown using the new dimensions 
    Bitmap imageToShow = Bitmap.createScaledBitmap(imageOriginal, imageToShowWidth, imageToShowHeight, true);

    //Show the image in the ImageView
    ImageView image = (ImageView) findViewById(R.id.image);
    image.setImageBitmap(imageToShow);
}
