Android get R.raw from variable
i have some sounds in a raw folder on my app. And sometimes i need to play a sound, but i don't know exactly which is.
String actualSound = "hit" playSound(mediaPlayer, R.Raw.actualSound));
I want to play the R.raw.hit but i don't know how to do that.
You can obtain the numeric ID of your raw resource using
Resources.getIdentifier() and then use it in your play function:
Resources res = context.getResources(); int soundId = res.getIdentifier(actualSound, "raw", context.getPackageName()); playSound(mediaPlayer, soundId);
Note that generally, you shouldn't do this. It is more efficient to access resources by numeric identifier (i.e.
R-qualified constant). This would especially matter if you were to do the above every time you want to play sound in a game. It is better to use a mapping of sound names (or better yet: enum values) to resource identifiers or even pre-loaded sound samples.
