That’s because a long is 64 bits and an int is 32 bits, not to mention you’re going from floating-point to integer. To go from long to int, you’re going to have to discard some information, and the compiler can’t/won’t do that automatically. You’re going to have to explicitly say so through a cast: Alternatively, you can use java.util.Random:
The ANSI escape sequences you’re looking for are the Select Graphic Rendition subset. All of these have the form where XXX is a series of semicolon-separated parameters. To say, make text red, bold, and underlined (we’ll discuss many other options below) in C you might write: In C++ you’d use In Python3 you’d use and in Bash … Read more
You should use: You can use various functions from the Color class to get the same effect of course. Color.parseColor (Manual) (like LEX uses)text.setTextColor(Color.parseColor(“#FFFFFF”)); Color.rgb and Color.argb (Manual rgb) (Manual argb) (like Ganapathy uses)holder.text.setTextColor(Color.rgb(200,0,0)); holder.text.setTextColor(Color.argb(0,200,0,0)); And of course, if you want to define your color in an XML file, you can do this:<color name=”errorColor”>#f00</color> because the getColor() function is deprecated1, you need to use it like … Read more
You can use filters with -webkit-filter and filter: Filters are relatively new to browsers but supported in over 90% of browsers according to the following CanIUse table: https://caniuse.com/#feat=css-filters You can change an image to grayscale, sepia and lot more (look at the example). So you can now change the color of a PNG file with filters. Source
The color plugin is only 4kb so much cheaper than the UI library. Of course you’ll want to use a decent version of the plugin and not some buggy old thing which doesn’t handle Safari and crashes when the transitions are too fast. Since a minified version isn’t supplied you might like test various compressors and make your own min version. … Read more
Add the same color of the background to the paragraph and then invert with CSS:
The last parameter to the rgba() function is the “alpha” or “opacity” parameter. If you set it to 0 it will mean “completely transparent”, and the first three parameters (the red, green, and blue channels) won’t matter because you won’t be able to see the color anyway. With that in mind, I would choose rgba(0, 0, 0, 0) because: it’s less typing, it keeps a … Read more
New approach (inspired by @Kamil-Kiełczewski solution)Takes degree, percentage, percentage and returns css hex color: Example: Original version: (still OK, just longer) Takes degree, percentage, percentage and returns css hex color: Example:
Transparency is controlled by the alpha channel (AA in #AARRGGBB). Maximal value (255 dec, FF hex) means fully opaque. Minimum value (0 dec, 00 hex) means fully transparent. Values in between are semi-transparent, i.e. the color is mixed with the background color. To get a fully transparent color set the alpha to zero. RR, GG and BB are irrelevant in this case … Read more
