Android Question how to stop particular mediaplayer while using multiple instances

[mkvidyashankar]

Hi

I am using multiple instances of Media player to play different combination of mediafiles. I would like to stop play of one particular audio file. How to do that?

 

[Erel]

Dim MediaPlayers As Map = CreateMap("song1": mp1, "song2": mp2)
'...
Dim mp As MediaPlayer = MediaPlayers.Get("song2")
mp.Stop

Thanks for the reply

I tried using the same

Dim index As Int = clv2.GetItemFromView(Sender)
    Dim idd As Int =clv2.GetValue(index)
    Dim mp As MediaPlayer=MediaPlayers.Get(idd)
    If mp.IsPlaying Then mp.Stop

but I am getting this error

** Service (starter) Create **
** Service (starter) Start **
** Activity (main) Create, isFirst = true **
** Activity (main) Resume **
Error occurred on line: 276 (Main)

Where is the code that adds the MediaPlayers to the map?

 

[mkvidyashankar]

hi
here is the code

ub CheckBox1_CheckedChange(Checked As Boolean)
    Dim index As Int = clv2.GetItemFromView(Sender)
    Dim idd As Int =clv2.GetValue(index)
    Dim cursor1 As Cursor
   
        cursor1= sql1.ExecQuery("SELECT * FROM table1 WHERE ID = " & idd )
        For i = 0 To cursor1.RowCount-1
            cursor1.Position=i
            'ID=cursor1.GetInt2(0)
            scheme= cursor1.GetString2(1)
            imagepath=cursor1.GetString2(2)
            desription=cursor1.GetString2(3)
            sound1=cursor1.GetString2(4)
            MediaPlayers.put(idd,sound1)
        Next
        cursor1.Close
       
    If checkbox1.Checked  Then
       
        spsample.Initialize
        If spsample.IsPlaying Then spsample.Stop
        spsample.Load(File.DirAssets,sound1)
        spsample.Play
    Else
        Dim mp As MediaPlayer=MediaPlayers.Get(sound1)
        If mp.IsPlaying Then mp.Stop
    End If
End Sub

 

[Erel]

sound1 is a string not a MediaPlayer.

Thanks, I changed and it works

Sorry some confusion, it is not working.

ub ChkBx_CheckedChange(Checked As Boolean)
    'Dim index As Int = clv2.GetItemFromView(Sender)
    Dim pnl As Panel = lst.FindPanelContaining(Sender)
    'Dim checkbox1 As CheckBox = pnl.GetView(2)
    Dim idd As Int =pnl.Tag
    Dim cursor1 As Cursor
   
        cursor1= sql1.ExecQuery("SELECT * FROM table1 WHERE ID = " & idd )
        For i = 0 To cursor1.RowCount-1
            cursor1.Position=i
            'ID=cursor1.GetInt2(0)
            scheme= cursor1.GetString2(1)
            imagepath=cursor1.GetString2(2)
            desription=cursor1.GetString2(3)
            sound1=cursor1.GetString2(4)
            MediaPlayers.put(idd,sound1)
        Next
        cursor1.Close
       
    If Checked  Then
        spsample.Initialize
        If spsample.IsPlaying Then spsample.Stop
        spsample.Load(File.DirAssets,sound1)
        spsample.Play
    End If   
    If Checked=False Then
        Dim mp As MediaPlayer=MediaPlayers.Get(idd)
        mp.Stop
    End If

still i dnt understand mp.stop(last line).

getting this error
java.lang.RuntimeException: Method: Stop not found in: java.lang.String


mp is assigned as string
how to stop the mediaplayer which is assigned in the previous line.

Sorry some confusion, it is not working.

You are NOT storing Mediaplayers in your list as said in #6
Your list contains STRINGS.
A String does not have a Stop method
