Programmatically set height on LayoutParams as density-independent pixels

Question

Is there any way to set the height/width of a LayoutParams as density-independent pixels (dp)? It looks like the height/width, when set programmatically, are in pixels and n

Answer 1

The answered solution didn't work for me, the height of the view was still off. I ended up with this, which works well:

protected int dp2px(int dp){
    final float scale = getResources().getDisplayMetrics().density;
    return (int) (dp * scale + 0.5f);
}

And if you want the other way round, pixels to dp ...

protected float px2dp(float px){
    DisplayMetrics metrics = Resources.getSystem().getDisplayMetrics();
    float dp = px / (metrics.densityDpi / 160f);
    return Math.round(dp);
}
