Set the OK Button to have an OnClickListener

public void onCreate(Bundle savedInstanceState) {
View okButton = findViewById(R.id.okButtonImg); //assume you are using custom img for OK
okButton.setOnClickListener(okButtonListener);
}

In the Click Listener invoke an Intent. In the Intent you can pass information using "putExtra"

        private OnClickListener okButtonListener = new OnClickListener() {

            public void onClick(View v) {
            Intent secondPageIntent = new Intent(getBaseContext(), SecondPage.class);
            secondPageIntent.putExtra("PASSVALUE","ANY  STRING HERE");
            startActivity(secondPageIntent);

            }
     };

In the second page use getExtras("PASSVALUE") to retrieve data that you passed

Answer-1)

For that you need to pass the value in intent and that value you get in another activity.

Intent i = new Intent(YourCurrentActivity.this,YourCallingActivity.this);
i.putExtra("key", YourValueToPassAnotherActivity);
startActivity(i);

Now you can get this value in your calling activity using bundle.

Bundle b = getIntent().getExtras();
b.getString("key");

Answer-2)

For that you need to create custom title bar. This might help you
