Back without press "back" button

Question

In AActivity, when button1 is press, then call BActivity.

Button b1= (Button)findViewById(R.id.button1);
b1.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent();
intent.setClass(AActivity.this, BActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);
}
});

In BActivity, I want that when button2 is press, then recall AActivity.

Button b2= (Button)findViewById(R.id.button2);
b2.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
//How to do?
}
});

I want back without press "back" button on keyboard. And replace with button in layout. How should I do?

When call back to AActivity, is it possible to run the onCreate() method?

Only you have to finish the activity by calling finish() method

Sample code

Button b2= (Button)findViewById(R.id.button2);
b2.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
finish();
}
});

I don't think it's good way to deal with onBackPress. It just suitable for Activity Stack,not all,like Fragment!In this case you should use – Albert.Qing Mar 22 '12 at 09:00

`FragmentManager ft = getSupportFragmentManager();` `ft.popBackStackImmediate();` – Albert.Qing Mar 22 '12 at 09:06

You'll get the "Back" button functionality by this simple code :) As the back button on the phone is just finishing the current activity causing previous activity on the activity stack to start again.

Button b2= (Button)findViewById(R.id.button2);
b2.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
finish();
}
});

In the onClick() method of button2, you could just put

finish();

or you could specify a new Intent with AActivity.class as the target.

Button b2 = (Button) findViewById(R.id.button2);
b2.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        Intent intent = new Intent();
        intent.setClass(BActivity.this, AActivity.class);
        intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        startActivity(intent);
    }
});

I think you should override onKeyDown() method to enable the back button functionality. Override back button to act like home button link will help you to achieve this.
