Feeding MediaPlayer with dynamic file

Question

Good day, I have a small app, it has one button. Whenever I press the button it makes sound using the MediaPlayer. The issue is that I can't find how to make same mediaplayer to play other sounds,

For example: I have list of 10 sounds, whenever I click on my button it randomly picks number from 1 to 10, afterwards it takes corresponding sound where randomly generated number is the position in the list and plays it.

The problem is what should I feed my MediaPlayer with in the bold area? MediaPlayer mpfn = MediaPlayer.create(getActivity(),R.raw.number1);

I'm new to android, and sorry in advance in case my question hurt your feelings. Thanks in advance.

same as the example, raw folder, they are already present in the project (local) — Stanislav Bondarenko, Jan 21 '17 at 11:06

Assuming the media files are stored in raw folder, you can play the songs in random this way:

First generate random number using Math.random() . Then play the corresponding music, this way:

    Random ran = new Random();
    int x = ran.nextInt(3);
    if(x==0)
    {
        mPlayer = MediaPlayer.create(this,R.raw.fst);
    }
    else if(x==1)
    {
        mPlayer = MediaPlayer.create(this,R.raw.sec);
    }
    else if(x==2)
    {
        mPlayer = MediaPlayer.create(this,R.raw.thd);
    }
    length = 0;
    try{mPlayer.prepare();}catch (Exception e){}

This shows how you can play randomly from 3 media files, the process for 10 files is no different. once its ready, you can play it using : mPlayer.start();

Thank you, I will try that – Stanislav Bondarenko Jan 21 '17 at 11:13
It's working, thank you. I was wondering if there is a way to replace the media file with variable? – Stanislav Bondarenko Jan 21 '17 at 13:20
you mean a variable for `R.raw.thd` ? – OBX Jan 21 '17 at 13:21
Yes, so I would be able to insert there any other file in run-time – Stanislav Bondarenko Jan 21 '17 at 14:02

At last I can answer this question myself. This was very simple to achieve, I've made string-array and stored all my sounds there in my own order. So whenever I got my random number I've been just picking this number and used it as item index in that string array.
