I don't want to finish() and start the last activity as all the data is shown in that, which will be loaded again if recreated.

推荐答案

基本上你想切换当前背景和previous背景的顺序。要做到这一点，你就可以开始了previous活动，并使用FLAG_ACTIVITY_REORDER_TO_FRONT标志：

Basically you want to switch the order of the current background and the previous background. To do this, you can start the previous activity and use the FLAG_ACTIVITY_REORDER_TO_FRONT flag:

Intent intent = new Intent(this, MyPreviousActivity.class);
intent.setFlags(FLAG_ACTIVITY_REORDER_TO_FRONT);
startActivity(intent);

所以，如果你有任务A，B，C和任务的C调用startActivity（）与活动B，那么B就会被带到活动堆栈的前面，所产生的顺序A，C，B，这是什么你问了。

So if you have tasks A, B, C and task C calls startActivity() with activity B, then B will be brought to the front of the activity stack, with the resulting order A, C, B, which is what you were asking for.
