The title is the question. I have saved a string value in the shared preference and i was able to access it in that class. Now i want to access it from a another method of another class. Tried some ways but didn't work.
The class that saves string inside shared preference:
Class trying to retrieve the username that was previously save in shared preference:
public class testSharedPrefernce extends Activity{
TextView tv;
@Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.lo);
tv = (TextView)findViewById(R.id.textView1);
SharedPreferences myPrefs = this.getSharedPreferences("myPrefs", MODE_WORLD_READABLE);
String name = myPrefs.getString("NAME", "YourName");
tv.setText(name);
}
}
Just make a constructor of that class which accepts the context.As example:
class Abc
{
Context contaxt;
public Abc(Context context)
{
this.context = context;
}
}
..........
..........
// now use this context to SharedPref..
SharedPreferences sp = PreferenceManager.getDefaultSharedPreferences(context);
Use below code for get preferences.
SharedPreferences myPrefs = this.getSharedPreferences("myPrefs", MODE_WORLD_READABLE);
boolean cbvalue = myPrefs.getBoolean("CHECKBOX", false);
String name = myPrefs.getString("NAME", "YourName");
String paswrd =myPrefs.getString("PASSWORD", "123");
Use below code for save preferences.
SharedPreferences myPrefs = this.getSharedPreferences("myPrefs", MODE_WORLD_READABLE);
SharedPreferences.Editor prefsEditor = myPrefs.edit();
prefsEditor.putString("NAME", "Dipak");
prefsEditor.putString("PASSWORD", "Dipak123");
prefsEditor.commit();
