推荐答案

我觉得要覆盖的home键的点击操作。您可以覆盖在你的活动像这样的这种功能。

I think you want to override the click operation of home button. You can override this functionality like this in your activity.

        @Override
        public boolean onOptionsItemSelected(MenuItem item) {
                switch (item.getItemId()) {
                case android.R.id.home:
                       Toast.makeText(getApplicationContext(),"Back button clicked", Toast.LENGTH_SHORT).show(); 
                    break;
                }
                return true;
        }
