You are not retrieving data from sharedpreferences modify code like this:

 sharedpreferences = getSharedPreferences(MyPREFERENCES, Context.MODE_PRIVATE);  
     SharedPreferences.Editor editor = sharedpreferences.edit();

    e1 = (EditText)findViewById(R.id.editText);
    e2 = (EditText)findViewById(R.id.editText2);

    String homewifi = sharedpreferences.getString(HOMEWIFI, "");
    String officeWifi = sharedpreferences.getString(OFFICEWIFI, "");

    e1.setText(homewifi);
    e2.setText(officeWifi);


        b1 = (Button)findViewById(R.id.button3);

       Context.MODE_PRIVATE);

        b1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                String homewifi  = e1.getText().toString();
                String officewifi  = e2.getText().toString();



                editor.putString(HOMEWIFI, homewifi);
                editor.putString(OFFICEWIFI, officewifi);
                editor.commit();
                Toast.makeText(MainActivity.this,"Thanks",Toast.LENGTH_SHORT).show();

            }
        });

String homewifi = e1.getText().toString(); – faisal iqbal Jun 09 '16 at 05:49
homewifi how to write it in brace where is ranksol? – faisal iqbal Jun 09 '16 at 05:50
@MasoomBacha It means you have save value as Ranksol and when you retrieve from sharedpreferences you have to set in editText as "Ranskol" ( with " quotes ) , right ? – Suhas Bachewar Jun 09 '16 at 05:52
no no Ranksol is manual string value i want to set string value which i get from edittext – faisal iqbal Jun 09 '16 at 05:54
e1.getText().toString(); this is save string as whatever you put inside the editText so you don't have to take care of that . while retrieve it will give result as previously saved both are completely same as previously saved – Suhas Bachewar Jun 09 '16 at 05:58
can i also save spinner in shareprefrence – faisal iqbal Jun 09 '16 at 06:00

when activity open again data not show in EditText.

Need to get data from SharedPreferences and call setText method of EditText's to show it when starting Activity Again.like:

....
e2 = (EditText)findViewById(R.id.editText2);
b1 = (Button)findViewById(R.id.button3);
sharedpreferences = getSharedPreferences(MyPREFERENCES, Context.MODE_PRIVATE);
if (sharedpreferences.contains(HOMEWIFI)) {
   String strHomeWifi = settings.getString(HOMEWIFI, "default value");
   e1.setText(strHomeWifi); 
}else if (sharedpreferences.contains(OFFICEWIFI)) {
   String strofficewifi = settings.getString(OFFICEWIFI, "default value");
   e2.setText(strofficewifi); 
}
...

@MasoomBacha: no check my answer . do it before `b1.setOnClickListener(new View.OnClickListener() {` line in your code – ρяσѕρєя K Jun 09 '16 at 05:20
e1.setText(strHomeWifi); here what is the str – faisal iqbal Jun 09 '16 at 05:23
@MasoomBacha: whole code is `String strHomeWifi = settings.getString(HOMEWIFI, "default value"); e1.setText(strHomeWifi);` – ρяσѕρєя K Jun 09 '16 at 05:29
@MasoomBacha: is there any issue in that line? – ρяσѕρєя K Jun 09 '16 at 05:29

I guess you forgot to set string from your SharedPreferences to both the edittext,

after saving it from edit text to sharedpreferences.

like

 e1 = (EditText)findViewById(R.id.editText);
            e2 = (EditText)findViewById(R.id.editText2);
            b1 = (Button)findViewById(R.id.button3);

            sharedpreferences = getSharedPreferences(MyPREFERENCES, Context.MODE_PRIVATE);

            if(!TextUtils.isEmpty(sharedpreferences.getString(HOMEWIFI))){
                e1.setText(sharedpreferences.getString(HOMEWIFI));
            }
            if(!TextUtils.isEmpty(sharedpreferences.getString(OFFICEWIFI))){
                e1.setText(sharedpreferences.getString(OFFICEWIFI));
            }

            b1.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    String homewifi  = e1.getText().toString();
                    String officewifi  = e2.getText().toString();

                    SharedPreferences.Editor editor = sharedpreferences.edit();

                    editor.putString(HOMEWIFI, homewifi);
                    editor.putString(OFFICEWIFI, officewifi);
                    editor.commit();
                    Toast.makeText(MainActivity.this,"Thanks",Toast.LENGTH_SHORT).show();

                }
            });
