Question

I want to call a listview adapter from another activies after insert record to sqllite db.

I cant call the adapter.notifyDataSetChanged() method. What is the best way to do it.

public void onClick(View v) {
    TextView item_name;
    item_name=(TextView) findViewById(R.id.eItemName);         
    Log.d("Insert: ", "Inserting ..");
    db.add_item(new Item(item_name.getText().toString()), getApplicationContext());

    // I want to call the method HERE!!!! 

    finish();   
}

Answer 1

Just

After finish() Current Activity, Call adapter.notifyDataSetChanged() from onActivityResult()in previous Activity (As I assumes your Listview in this previous Activity).

Also start your Current Activity from Previous Activity using startActivityForResult();

Or if you have reference of List Adapter in this Activity, then using that reference call adapter.notifyDataSetChanged(). (But I think its not a good practice)
