Re: [android-developers] Re: I have problem working with SHARED PREFERENCES, I think is project specific... i used the same before without errors but now get error

[lselwd]

 my problem solved but another problem arises:
used:
  // public constructor
   public CannonView(Context context, AttributeSet attrs)
   {
  super(context, attrs); // call super's constructor
  *activity = (Activity) context; *
.
..
SharedPreferences prefs = *activity.*getSharedPreferences("top5", 
MODE_PRIVATE);

well if i have (same app) an activity and a Canvas like:
*public class CannonView extends SurfaceView *
*   implements SurfaceHolder.Callback*
*{*
+
*public class CannonGame extends Activity*
*{*
And want record user name played what to do ... I use shared pref 
in CannonView to record 5 top scores... when used get username dialog 
success but in 
   public void onCreate(Bundle savedInstanceState)  // Activity
   {
  super.onCreate(savedInstanceState); // call super's onCreate method
  setContentView(R.layout.main); // inflate the layout
  //userName = insertUser() ; ///  line 104
  // get the CannonView
  cannonView = (CannonView) findViewById(R.id.cannonView);
  
  //cannonView.asignVars(userName);//insertUser()
  cannonView.userName=insertUser() ;

user is not recorded like non pass from Activity class (Main) to non 
Activity class(canvas)... well is it because execution moved to canvas or 
insertUser() may malfunction(thie latter not think so hence toast of user 
name show works), well?

[Jayu Sagar]

Try this piece of code


Isn't there a getContext() method for SurfaceView?

getContext().getSharedPreference();

[android-developers] Re: I have problem working with SHARED PREFERENCES, I think is project specific... i used the same before without errors but now get error

[Seshu]

Hi,
 If u r creating sharedpreferences in our activity class means
then it wont show any error other wise if u r creating shared
preferences in other java class then it ll shows errors.
in that case u need to pass the context or activity object.

this is the sample code

public class SharedPrefEx {

public void saveData(Context context, String value) {
SharedPreferences prefs = 
context.getSharedPreferences("MyPrefs",
Context.MODE_PRIVATE);
SharedPreferences.Editor editor = prefs.edit();
editor.putString("One", value);
editor.commit();
}
}

u can call this method by creating object in our activity class i.e.
SharedPrefEx  sharedPrefs = new SharedPrefs();
sharedPrefs.saveData("Seshu");

[lselwd]

In a Canvas game if we have a class like:
*public class CannonView extends SurfaceView *
*   implements SurfaceHolder.Callback*
*{*
how transfer from this a var value to this
*public class CannonGame extends Activity*
*{*
without using static vars?
