send data from page1 to page2 and save it

Question

I just want to know how to use SharedPrefreneces to pass data from page1 to page2 and save the data in page2.

I tried this code:

In page 1:

String strSource = source1.getText().toString();
SharedPreferences sharedPreferences = getSharedPreferences(FileName,Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPreferences.edit();
editor.putString("sourceText",strSource);
editor.commit();

Page 2:

SharedPreferences sharedPreferences = getSharedPreferences(FileName,Context.MODE_PRIVATE);
String defaultValue = "DefaultValue";
String sourceText = sharedPreferences.getString("sourceText",defaultValue);
source1.setText(sourceText);

Pref save data. If you uninstall your app or clear pref then it's clear. you don't want to pass one screen to other screen. you just save and use in all screen — Joker, Sep 04 '19 at 13:11

If you want to pass data from page1 to page2 then it is possible via intent.

Example: In Kotlin

    val intent =Intent(this,Page2Activity::class.java)
    intent.putExtra("key","data")
    startActivity(intent)

@HamzaDev Then save it when you got it back from intent. – Mahdi-Malv Sep 04 '19 at 14:04
String data = getIntent().getSerializableExtra("key"); – Auxano Services Sep 05 '19 at 04:46
