Resize images in GridView on Android

I follow this tutorial to create a GridView:

This line:

imageView.setLayoutParams(new GridView.LayoutParams(85, 85));

Size 85x85 is great for my Wildfire, but on HTC Desire it looks very small. How can I change the image size according to the screen?

I have 2 different layouts, but Gridview hasn't any attribute in the XML files to change the image size.

Similar to willytate's answer, but you're better off creating a dimension value in an xml (for 85dp) and retrieving it like so:

  int size = resources.getDimensionPixelSize(R.dimen.your_dimension);

That way, the width/height will be sized consistently, without you having to worry about much.

You could try to make an adjustment based off the pixel density of the current device you are on.

DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);
switch(metrics.densityDpi){
     case DisplayMetrics.DENSITY_LOW:
                imageView.setLayoutParams(new GridView.LayoutParams(lowVal, lowVal));
                break;
     case DisplayMetrics.DENSITY_MEDIUM:
                imageView.setLayoutParams(new GridView.LayoutParams(medVal, medVal));
                break;
     case DisplayMetrics.DENSITY_HIGH:
                 imageView.setLayoutParams(new GridView.LayoutParams(highVal, highVal));
                 break;
}
