注意:

我不想使用Intent，因为我想拥有Activity01 ，就像我按下Activity02

I do NOT want to use Intent, because I want to have Activity01 as if I pressed the back button from Activity02

请问该怎么做?

推荐答案

为什么不能使用Intent?单击按钮时，您可以使用 FLAG_ACTIVITY_CLEAR_TOP . 如果要保留Activity的原始实例，则可以将此标志与

Why can't you use an Intent? You can use the FLAG_ACTIVITY_CLEAR_TOP when you click the button. If you want to preserve the original instance of the Activity, you can use this flag in conjunction with FLAG_ACTIVITY_SINGLE_TOP.

您是否曾经希望能够按下Activity03中的按钮以返回到Activity02?如果您始终希望它返回到Activity01，则可以在清单中的Activity02上使用android:noHistory="true"，而只需在Activity03上调用finish().

Do you ever want to be able to press a button from Activity03 to go back to Activity02? If you ALWAYS want it to go back to Activity01, you could alternatively use android:noHistory="true" on Activity02 in the manifest and just call finish() on Activity03.
