Usage

From source file:Main.java

public static float getAttributeDimension(final Context context, final Resources.Theme theme, final int resId) {
    final TypedValue typedValue = new TypedValue(); // create a new typed value to received the resolved attribute
    // value//from  w w  w  .j a va  2  s.  c o m
    final DisplayMetrics displayMetrics = context.getResources().getDisplayMetrics();
    if (!theme.resolveAttribute(resId, typedValue, true)) // if we can't resolve the value
    {
        throw new Resources.NotFoundException("Resource ID #0x" + Integer.toHexString(resId));
    }
    if (typedValue.type != TypedValue.TYPE_DIMENSION) // if the value isn't of the correct type
    {
        throw new Resources.NotFoundException("Resource ID #0x" + Integer.toHexString(resId) + " type #0x"
                + Integer.toHexString(typedValue.type) + " is not valid");
    }
    return typedValue.getDimension(displayMetrics); // return the value of the attribute in terms of the display
