按钮回去appliaction [英] Button to go BACK in appliaction

问题描述

我需要code一键返回到主应用程序的活动。

I need to code a button to go BACK to the main application activity.

public void onGotoMainActivity(View View)
    {
         Intent intent = new Intent(View.getContext(), MainActivity.class);
         this.startActivity(intent);
    }

主要活动已启动，并没有被破坏。因此，我不认为这将是一个新的意图也不应该启动活动？应该不是它只是调用的主要活动回焦点？

The Main activity is already started and has not been destroyed. So I don't think this would be a "new" intent nor should it "start activity"? Shouldn't it merely call the main activity back to focus?

推荐答案

您也可以使用此功能。

Intent intent = new Intent();
setResult(RESULT_OK, intent);
finish();
