Question

I have following class with a constructor :

public class TestAdapter {

    protected static final String TAG = "DataAdapter";

    private final Context mContext;
    private  SQLiteDatabase mDb;
    private  DatabaseHandler mDbHelper;

//  private static SQLiteDatabase mDb2;
//  private static DatabaseHandler mDbHelper2;


    public TestAdapter(Context context) {
        this.mContext = context;
        mDbHelper = new DatabaseHandler(mContext);
    }

In this very class I have a setFlag() method which I need to call from following method –

@Override
        protected void onPostExecute(String result) {
            // tv.setText(result);
            Log.e("result", result);
            if (Integer.parseInt(result) == 1) {
                flagValue = 1;
                Log.e("my","flag value set");
                //TestAdapter t =new TestAdapter();
                //setFlag()



            }

the commented part is where I need to call that method but I don’t know how to create object of the “TestAdapter” class. If I make setFlag() static in that class, then other instances being used in that method will not work because they are not static. F1 F1 F1

EDIT: I am given to understand that context exist for an activity but this class in which I need to create the object is not an activity..its just a java class which has methods to sync local database with server database.

First declare in your Activity first declare on top Context context = null;

Then in onCreate context = this;.

Now you can use your method like:

TestAdapter t = new TestAdapter(context); t.setFlag();
