java - Playing musics with ImageButton android -

i have list of music (.mp3) want played imagebutton , want play each sound id

first, have database has field _id. then, tried

 final string ambil = kata.get(3) 

for retrieving _id query used. then, used

speaker.settag(ambil); 

speaker imagebutton want tag each button _id make sound different each other.

then, ordered of sound file have this

int names[] = {r.raw.a,r.raw.a,r.raw.c}; 

finally, want create mediaplayer this

mediaplayer mp = mediaplayer.create(lazyadapter.this, r.raw.names[ambil]); 

is algorithm right ?

for now, give hint how done in simple way. can create array raw resources:

 int names[] = new int {r.raw.a,r.raw.b,r.raw.c}; 

don´t make string array have done it, not work. use example above , create mediaplayer this:

 mediaplayer mp = mediaplayer.create(lazyadapter.this, names[0]); 

edit

from example above, see wrong things.

first, can´t pass string identify number of array. did this:

     final string ambil = kata.get(3) 

and trying resource mediaplayer like:

     mediaplayer mp = mediaplayer.create(lazyadapter.this, r.raw.names[ambil]); 

there pass string resource names[] ---> r.raw.names[ambil]]; don´t write r.raw.names[], write names[].

also, have pass integer value array like:

      names[0] 

the question is, integer database, id, value? explanation, if write names[0], means first value of array (because arrays starts 0). in case, refer resource r.raw.a . if want refer second song, have write names[1].

i don´t know how have database implemented , in way give _id. sure give _id in way, not higher number of resources. if create autoincrement id, not work in case, when value higher number of songs.
