推荐答案

是的，你可以覆盖后退按钮

Yes you can override that back button

public void onBackPressed() {

 Intent start = new Intent(currentclassname.this,which activity u want.class);
    startActivity(start);
    finishActivity(0);
 }

通过这个你可以在任何活动而移动。这是非常容易和简单的方式

By this you can move on any activity. This is very easy and simple way
