  • You can use shared preferences to save toggle current status(true/false) on destroy of acticity 1. And read those preferences when you come to activity again. – Brijesh Kumar Jan 11 '17 at 06:26
  • But if i use Shared preference the value will be remain after killing the application.i want first time all are on that's why i can't use.@brijeshkumar – Vikash Kumar Jan 11 '17 at 06:30
  • If u want first time all ON, set default value true in shared preferences while reading shared preferences. – Brijesh Kumar Jan 11 '17 at 06:36

This is a very general Scenario in Android UI flow: One way could be saving toggle state in Shared preferences as explained here:

You can save the toggle state in onPause() of Activity in Shared preferences and restore the saved values in onResume() of the Activity

you can transfer infomation from activity1 to activity2 by using intent and bundle

-------------------Activity1---------------click

Intent intent = new Intent(this, Activity2.class); 
intent.putExtra("Text", mText); 
intent.putExtra("TextColor", mTextColor); 
intent.putExtra("TextSize", mTextSize); 
intent.putExtra("TextBold", mTextBold); 

startActivity(intent);

-----------------------------Activity2--------------oncreate

Bundle extras = getIntent().getExtras(); 
mText = extras.getString("Text"); 
mTextColor = extras.getInt("TextColor"); 
mTextSize = extras.getFloat("TextSize"); 
mTextBold = extras.getBoolean("TextBold");

in your app, getBoolean is ok
