Populate Android Listview with data extracted from a database

I am a newbie to Android programming.I want to use data inputted into an SQLite database to populate an Android Listview. However, Android keeps highlighting the SimpleCursorAdapter below as error. Can anyone help?

try this create one method in your adapter like this
public ArrayList<Data_Model> getArray() {
return arrayList;
}
now on your button click just call this method
upload.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
ArrayList<Data_Model> arrayList= adapter.getArray();
}
});
ask me in case of any query

Getting data from BaseAdapter in Service class

I have a BaseAdapter class using ViewHolders to display a list of checked apps. I store the checked apps with SharedPreferences so the apps that are checked stay checked. What I am trying to achieve is getting the checked apps in my Service Class as ideally store it in an arraylist or something of the sort.
The problem is that the keys are what I used to the get the values are in the BaseAdapter class too and I can't get it from the service class so I had to recreate the methods for getting the list of packages and iterating through with a for loop.
I also cannot checked if the holder checkbox is checked in my Service class since that is done in my BaseAdapter class.
Despite passing the context in BaseAdapter and using getApplicationContext with SharedPreferences I cannot get the list of checked apps in the service class. I am not sure where to turn now. I have tried everything from messing around with static variables, trying everything with getting the context from the BaseAdapter class etc.
Here is my Adapter Class (I have commented where I get the apps which are checked):

Ultimately, I can just tryna get the job done for getting a list of checked apps in my service class. So no matter what whenever I have the service running I have the list of checked apps. Whenever the app opens, re opens, restarts or does whatever, etc.
Help is appreciated. Let me know if there is anything else I can add.

I ended up creating a new database in my SharedPreferences to store only checked apps.

Inside your DataBaseHandler.java , Make the following change
public List<Shakhes> getAllShakhes() {
List<Shakhes> shakhess = null;
Cursor c = database.rawQuery("SELECT * FROM TBL_MAHRIE",null);
//Cursor c = database.query("TBL_MAHRIE", new String[] { "ID", "COL_SAL", "COL_NERKH" }, null, null, null, null, null);
shakhess = new ArrayList<Shakhes>();
if (c.moveToFirst()) {
do {
Shakhes p = new Shakhes();
p.setId((int) c.getLong(c.getColumnIndex("ID")));
p.setSal(c.getString(c.getColumnIndex("COL_SAL")));
p.setNerkh(c.getString(c.getColumnIndex("COL_NERKH")));
shakhess.add(p);
} while (c.moveToNext());
return shakhess;
}
return shakhess;
}
}
code the line Shakhes p = new Shakhes(); inside do-while loop. Otherwise it will overwrite the old one, and the same will be added in arraylist.
