Question

我很想知道。如果存在一种办法,我们就能够回到原先装满负荷的活动,而不必从零头重载其内容。由于我的申请从一个网站下载内容,我不想每次下载内容,而只是明确提到。

Answer 1

http://www.un.org/Depts/DGACM/index_french.htm 活动, 您将在方法<条码>上对该项活动作出说明。

EDIT:

                Intent intent = new Intent(this,SecondActivity.class);
                startActivityForResult(intent, RESULT_OK);

以及

public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (resultCode == RESULT_OK) {
       // When you are back from second Activity you are l以及here ..
       // do what ever you want to, without re Creating the this Activity 
    }
}

Answer 2

活动直到我们完成,或完成。您可使用roid状物的后功能。

Activity.this.dispatchKeyEvent(new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_BACK));

On click of user defined back button . This code will act same as back functionality of device back button.

And yes don not start activity or finish activity or set flag while moving between activities , that can change your result a lot
