Question

Okay, first off, i started (trying) to learn Java about 2 days ago.
im trying to make an application that lists all installed applications (activityInfo.loadLabel)
and i want to launch the application on item click (activityInfo.packageName)
i have these stored in a list of AppItems

class AppItem{
    String _appname;
    public String getAppname(){return _appname;};
    public void setAppname(String value){_appname = value;};
    String _app;
    public String getApp(){ return _app; };
    public void setApp(String value){_app = value; };
}

I can add an array of strings to my listview just fine.
but how do i add 2 different values to the same row (so to speak) in a listview – in Java.
please tell me if you dont understand my question – and il’l try to elaborate best possible

here is my code:

ArrayList<AppItem> apps;
    @Override
protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);


        final Intent mainIntent = new Intent(Intent.ACTION_MAIN, null);
        mainIntent.addCategory(Intent.CATEGORY_LAUNCHER);
        final List<ResolveInfo> pkgAppsList = getPackageManager().queryIntentActivities(mainIntent, 0);
        AppItem appItem = new AppItem();
        for (ResolveInfo applicationInfo : pkgAppsList) {
            appItem._appname = (String) applicationInfo.activityInfo.loadLabel(getPackageManager());
            appItem._app= applicationInfo.activityInfo.packageName;
            apps.add(appItem);
        }

        ArrayAdapter<AppItem> adapter = new ArrayAdapter<AppItem>(this,android.R.layout.simple_list_item_1,apps);

        ListView listView = new ListView(this);     
        listView.setAdapter(adapter);
         setContentView(listView);

         listView.setOnItemClickListener(new OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position,
                    long id) {
                String item = ((TextView)view).getText().toString();            
                Toast.makeText(getBaseContext(), item, Toast.LENGTH_LONG).show();

            }
        });

    }
class AppItem{
    String _appname;
    public String getAppname(){return _appname;};
    public void setAppname(String value){_appname = value;};
    String _app;
    public String getApp(){ return _app; };
    public void setApp(String value){_app = value; };
}

or
is there an alternative to using

Intent LaunchIntent = getPackageManager().getLaunchIntentForPackage("com.package.address");
startActivity(LaunchIntent);

would i be able to start an application via its label name?

Answer 1

Your ArrayAdapter displays the content of AppItem.toString() in the layout you give it.

You can override toString() to display the label:

public void toString() {
    return _appName;
}

in the onItemClick, you can get the item by calling

AppItem item = (AppItem) parent.getItemAtPosition(position);

or, given that appItem is accessible (either final or a field of your activity rather than a local variable to the method)

apps.get(position);

You can then have the package and call the activity :

Intent intent = getPackageManager().getLaunchIntentForPackage(item.getAapp());
