getActivity() where it is defined?

Question

I\'m very new to android and I\'m following this example.

The code says we need to do these steps to get an dialog box:

AlertDialog.Builder builder =         


        

Answer 1

// 1. Instantiate an AlertDialog.Builder with its constructor

AlertDialog.Builder builder = new AlertDialog.Builder(yourActivityName.this);

// 2. Chain together various setter methods to set the dialog characteristics

builder.setMessage(R.string.dialog_message).setTitle(R.string.dialog_title);

// 3. Get the AlertDialog from create()

AlertDialog dialog = builder.create();

// 4. Show the AlertDialog

dialog.show();
