Question

well there are 3 activities say Act1, Act2 and Act3.

in Act1 there are three buttons say But1, But2 and But3.

if we click any of the 3 three buttons it will end up showing Act2.

in Act2 there is only one button say Done.

my problem is when i click on the button Done in Act2 i should get the information about the button which is clicked in Act1 to show Act2 in a TextView in Act3.

i think i have made it clear..

i just need to know how to pass the information of the button click in Act1 to Act3

should i use bundles or something else? pls help me out with the logic and if possible a sample code? 🙂

You can use SharedPreferences to store which button was pressed.

   SharedPreferences appSharedPrefs = PreferenceManager.getDefaultSharedPreferences(this.getApplicationContext());
                Editor prefsEditor = appSharedPrefs.edit();

    Button b1 = (Button) findViewById(R.id.button1);
    b1.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    // TODO Auto-generated method stub
                prefsEditor.putString("buttonPressed", "Button1");
                prefsEditor.commit();

                }
            });

    Button b2 = (Button) findViewById(R.id.button2);
    b2.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    // TODO Auto-generated method stub
                prefsEditor.putString("buttonPressed", "Button2");
                prefsEditor.commit();

                }
            });

    Button b3 = (Button) findViewById(R.id.button3);
    b3.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    // TODO Auto-generated method stub
                prefsEditor.putString("buttonPressed", "Button3");
                prefsEditor.commit();

                }
            });

And in the Activity in which you want to fetch which button was pressed:

SharedPreferences appSharedPrefs = PreferenceManager.getDefaultSharedPreferences(this.getApplicationContext());
String whichButton = appSharedPrefs.getString("buttonPressed", "");
if(whichButton.equals("Button1")
 //do something
if(whichButton.equals("Button2")
 //do something
if(whichButton.equals("Button3")
 //do something
