Question

Why can I not pass this as Context in following code?
I am getting error

The constructor DataManager(new View.OnClickListener(){}) is undefined

I am new to android programming, so sorry if question is weird!!

Any help would be great.

    btn.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {
            // TODO Auto-generated method stub

            Log.d("vkx", "clk insert");
String qq="insert into users(id,name,password) values ('6','usrs','passs')";
            DataManager dm=new DataManager(this);
            dm.SqliteExecutenonquery(qq);

            Log.d("vkx", "clk insert done");
        }
    });

I have my DataManger class

        public DataManager(Context cont) {
    super(cont, DBname, null, DBver);
}
    ....

So what you are doing is when instantiating DataManager, You are not passing a context as a paramater but actually your instance of OnClickListener.

DataManager dm=new DataManager(YOUR_CLASS_NAME.this);

YOUR_CLASS_NAME should be the Activity class name. ie

class MyClass extends Activity{

  public onCreate(Bundle savedInstanceState){
    Button btn = new Button();
    btn.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View arg0) {
           DataManager dm=new DataManager(MyClass.this);

        }
    });

  }
}

Give this a try and let me know how it goes
