我需要使用活动堆叠吗？

Question

我这里有个问题，我不知道为什么会这样。

activity A - login
activity B - list
activity C - profile

1. I have an activity A, B and C.
2. From activity A, I can open activity B.
3. From activity B, i can open activity C.
4. When I press the back from activity C, it goes back to activity A and I want it to be in activity B. 

片段来自 activity C:

@Override
    public void onBackPressed() {
        // TODO Auto-generated method stub
        super.onBackPressed();
    }

片段来自 activity B:

@Override
        public void onItemClick(AdapterView<?> parent, View view,
                int position, long id) {
            // TODO Auto-generated method stub
            Log.d("Clicked item id", " "+ id); 
            Intent i = new Intent(getApplicationContext(), ChildProfile.class);
            startActivity(i);
            finish();
            }

片段来自 activity A:

 Intent i = new Intent(getApplicationContext(),Children.class);
                      startActivity(i);
                      finish();

Answer 1

当你打开 Activity C 你正在完成 Activity B

所以只需从 Activity B class 代码中删除 finish()。当你调用 Intent

Answer 2

加入Activity C

@Override
    public void onBackPressed() {
        // TODO Auto-generated method stub  
           Intent i = new Intent(C.this, B.class);
            startActivity(i);
          super.onBackPressed();
            }

或删除 Activity B

中的 finish();
