Is there any way to sort a listview of installed packages?

Erel · Jul 20, 2011

Add the items to a List and then sort the list with List.Sort.
If you also have an icon then you can use a Map together with the list. First sort the list and then for each item get the icon from the Map.

Yes I do have an icon. Do you have an example of how this is done?

Erel · Jul 21, 2011

Create a map and a list.
Add all the packages names to the list.
Add all the names and icons to the map.
Sort the list.
Go over all the items (names) in the list and grab the icon from the map.

If it doesn't work for you then please post your code.

I was able to get the labels and sort them but as far as creating the map and then creating a relationship no go.

B4X:

Sub PopulateList
Dim packages, packagessort As List
Dim bt(500) As BitmapDrawable
listview1.Visible = True
Dim map1 As Map
packages = pm.GetInstalledPackages
packagessort.Initialize
For i = 0 To packages.Size - 1
    packagessort.Add(pm.GetApplicationLabel(packages.Get(i)))
Next 
packagessort.Sort(True)
For i = 0 To packagessort.Size - 1
    'bt(i) = pm.GetApplicationIcon(packages.get(i))
    'listview1.AddTwoLinesAndBitmap2(pm.GetApplicationLabel(packages.Get(i)),"",bt(i).Bitmap,packages.Get(i))
    listview1.AddSingleLine(packagessort.Get(i))
Next
map1.Initialize
Dim items As String
Dim icns As BitmapDrawable
For i = 0 To packages.Size - 1 
    items = packages.Get(i)
    bt(i) = pm.GetApplicationIcon(packages.get(i))
    Map1.put(packages.Get(i),Items(0))
    Map1.put(bt(i).Bitmap)
Next

End Sub

Look at the order of things Erel gave you:

Create a map and a list
Add all the packages names to the list.
Add all the names and icons to the map.
Sort the list.
Go over all the items (names) in the list and grab the icon from the map.

Not:

Create a map and a list.
Add all the packages names to the list.
Sort the list.
Add all the names and icons to the map.

that you appear to have done.

What I was trying to do was do them separately and then combine them. So what I did was create the list of package labels and then sorted them. That worked. I know that the idea is to use the index of the packages before sort to link the list and the map together but I couldn't get the map part to work.

You have missed

Go over all the items (names) in the list and grab the icon from the map.

B4X:

    Map1.put(packages.Get(i),Items(0))
    Map1..put(bt(i).Bitmap)

is wrong, have a look at the help for maps and how to add a key/value pair.

Also it is the package label not the name that needs to be the map key

I could write the code for you but I think you will learn more if you investigate how to do things yourself.
