Music app

[Kelechi Ekezie]

Ok so I created a music app and I created a Next button and I set the button on touch 

Then I used

function btnNext_OnTouch() {

player.Next()} 

But I got the error player.Next is not a function 

Note that player.Play, player.Pause and player.Stop works fine though.

Well, 'Next' is not a method of the MediaPlayer component. https://symdstools.github.io/Docs/docs/app/CreateMediaPlayer.htm

How would the MediaPlayer know what file to play next? You would likely need to maintain a playlist and upon btnNext_OnTouch:
player.Stop

player.SetFile([the-next-file-in-the-list])

player.Play

Can u give  a sample code regarding how to set the next file in list please

Thanks in advance

Hi,

First you'd need a list of music files

   See https://symdstools.github.io/Docs/docs/app/CreateList.htm

Second create the media player and setfile (first music file in the list) 

  See https://symdstools.github.io/Docs/docs/app/CreateMediaPlayer.htmand 

Third set index to zero

   index = 0

Fourth a button with OnTouch (Next)

   See https://symdstools.github.io/Docs/docs/app/CreateButton.htm

In the OnTouch

   add 1 to index

   if index is greater than list.GetLength then index = 0

   Retrieve from the list GetItemByIndex(index), SetFile on the Media Player

Regards, ah

Would you be kind enough to write this code for me, pls

HI,

Probably the easiest way is to copy a Sample and modify it

Touch the rocket icon in the top-right, scroll down to Audio Player, touch it, then touch the left-bottom  icon, then paste into a new app.

Change Spinner to List

spin = app.AddList( lay,"[No tracks found]" );

player.SetFile( p + "/" + spin.GetItemByIndex(0).title );

After the block of code for the Stop Button add code for a Next Button

//Create 'Next' button.

btnNext = app.CreateButton( "Next", 0.4, 0.1 )

btnNext.SetOnTouch( btnNext_OnTouch )

lay.AddChild( btnNext ) 

        index = 0

After the btnStop functon add 

//Handle 'Next' button.

function btnNext_OnTouch() {

index += 1

if (index >= spin.GetLength() ) index = 0;

alert(p + "/" + spin.GetItemByIndex(index).title)

player.SetFile( p + "/" + spin.GetItemByIndex(index).title );

}

If you have got a lot of music (in the music folder) the screen will be overfull, 
so you could hide the list, or use a scroller.

Hi

Playing the next or previous file requires you to have a basic understanding of javascript arrays.

I created a public project of Music Player which you can read here

Or you can view the code on GitHub here
