Android - 模拟主页点击

Question

我知道在活动中调用finish()会产生与用户单击Back按钮相同的结果; Home按钮有类似的东西吗？(想要在某些动作后自动显示主屏幕).

编辑:另外,我会赞赏菜单和搜索按钮.

谢谢!

Answer 1

你可以简单地使用Intent:

Intent i = new Intent(Intent.ACTION_MAIN);
i.addCategory(Intent.CATEGORY_HOME);
startActivity(i);

Answer 2

家:

Intent showOptions = new Intent(Intent.ACTION_MAIN);
showOptions.addCategory(Intent.CATEGORY_HOME);
startActivity(showOptions);

菜单:

openOptionsMenu();
// this won't work from onCreate
// if anyone has idea how it would work
// please post it as response

Answer 3

startActivity(new Intent(Intent.ACTION_MAIN).addCategory(Intent.CATEGORY_HOME));
