Question

In an given Android activity, I would like to start a new activity for the user at some point. Once they leave the first activity and arrive at the second, the first activity is hidden..

Now my question is

I want to bring back the first activity (i dont want to create a new instance of the first activity but to bring back the already existing instance of the first activity) when a button is clicked in the second activity …

thanks 🙂

Answer 1

so simple. integrate the below code in your second activity

Button b = (Button)findViewById(yourbuttonid here);
b.setOnClickListener(new View.onClickListener(){
    public void onClick(View v){
        finish();
    }
});

This will work
