Basic tutorial on android development—SharedPreferences Reading and Writing

public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
(savedInstanceState);
setContentView(.activity_main);
}
public void onClick(View v) {
switch (()) {
case .button1:
SharedPreferences sp = ("myxml", Context.MODE_PRIVATE);
Editor editor = ();
("name", "nanguabing");
("age", 20);
//Permanent operation to storage device
();
(this, "Write to sp completed", 1).show();
break;
case .button2:
SharedPreferences sp1 = ("myxml", Context.MODE_PRIVATE);
String name = ("name", "nobody");
int age = ("age", 0);
(this, "name=" + name + ",age=" + age, 1).show();
break;
default:
break;
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(.activity_main, menu);
return true;
}
}
