SharedPreferences pref = getSharedPreferences(MY_ADDRESS, Activity.MODE_PRIVATE);
String name = pref.getString(NAME, "");
String address = pref.getString(ADDRESS, "");
...
TextView tvName = (TextView) findViewById(R.id.name);
tvName.setText(name);
TextView tvAddress = (TextView) findViewById(R.id.address);
tvAddress.setText(address);
...

Editor editor = pref.editor();
name = tvName.getText().toString();
editor.putString(NAME, name);
address = tvAddress.getText().toString();
editor.putString(ADDRESS, address);
...
editor.commit();
