android: How to populate a spinner with a string[] which is a list of installed packages?

Question

 final Intent mainIntent = new Intent(Intent.ACTION_MAIN, null);
    mainIntent.addCategory(Intent.CATEGORY_LAUNCHER);
    final List pkgAppsList = this.getPackageManager().queryIntentActivities( mainIntent, 0);
    final String[] apps = (String[]) pkgAppsList.toArray();
    Spinner appSpinner = (Spinner) findViewById(R.id.spinner1);
    ArrayAdapter<CharSequence> appAdapter = new ArrayAdapter(this, apps, android.R.layout.simple_spinner_item);
    appAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    appSpinner.setAdapter(cloudAdapter);

The previous code is throwing out errors for me in eclipse. I understand how to get the list of installed apps, and I understand how to populate a spinner using the createFromResource method. However I've never attempted to do so in this manner? Anyone able to direct me in the right direction?

Can you post the error here. So we can see what is going wrong? — Flo, Mar 17 '11 at 08:40
I know it's late, but still...There's no ArrayAdapter that accepts a list of objects as its 2nd arg. — Alex Kreimer, Nov 04 '13 at 16:04

Eventough it is late, you should use this constructor of ArrayAdapter instead :

ArrayAdapter<String> appAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, apps);
appAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
appSpinner.setAdapter(appAdapter);

Create a file named arrays.xml inside values folder.

Inside that give:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string-array name="array_name">
        <item>value1</item>
        <item>value2</item>
    </string-array>
</resources>

Then inside your spinner,give:

ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this, R.array.array_name, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_item);
spinner.setAdapter(adapter);

Hope this may work for you.

I am aware of how to do this. I'm trying to populate the spinner with an array created programmatically from the list of installed apps.... — Stev0, Mar 17 '11 at 07:21
