Back button works like home

Question

Is it possible to change this code:

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if (keyCode == KeyEvent.KEYCODE_BACK) {

    }
    return super.onKeyDown(keyCode, event);
}

so that when I click on back button it works like a home button?

Answer 1

try this,

@Override
    public void onBackPressed() {
        Intent backtoHome = new Intent(Intent.ACTION_MAIN);
        backtoHome.addCategory(Intent.CATEGORY_HOME);
        backtoHome.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        startActivity(backtoHome);
    }

Adding this to your Activity, will make it look like your app is responding to a Home Button Click event

   moveTaskToBack(true);
}

And also see this

Answer 3

@Override
public void onBackPressed()
    //super.onBackPressed();
    NavUtils.navigateUpFromSameTask(this);
}

If something doesn't work like expected try it with uncommented

    super.onBackPressed();
