How to Use Single Text for every Class in a Project Using SHARED PREFERENCE:


Here is my MAIN CLass ie.., LAUNCHER. I am using a textviewand keeping in Sharedpreference as sp object and calling that textview in other class using sp.getSharedpreferenc Method:




package com.babu.sharedpreferencee;
import android.app.Activity;
import android.content.Intent;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;

public class MainActivity extends Activity {

 EditText edt;
 SharedPreferences sp;


 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.share);

  edt=(EditText)findViewById(R.id.edt1);

  Button b=(Button)findViewById(R.id.btn1);
  b.setOnClickListener(new OnClickListener() {

   @Override
   public void onClick(View arg0) {
    // TODO Auto-generated method stub
    String s=edt.getText().toString();

    SharedPreferences sp = getSharedPreferences("prefs", 0);

    SharedPreferences.Editor editor = sp.edit();

    editor.putString("enteredname", s);

    editor.commit();
    
    



    Intent i=new Intent(MainActivity.this,Second.class);
    startActivity(i);



   }
  });




 }



}
