推荐答案

我不知道你的意思是通过最小化的东西。如果你想隐藏您的应用程序和present你可以使用下面的意图主屏幕上的用户。

I'm not sure what you mean by minimize. If you want to hide your app and present the user with the homescreen you can use the following intent.

Intent startMain = new Intent(Intent.ACTION_MAIN);
startMain.addCategory(Intent.CATEGORY_HOME);
startMain.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(startMain);

虽然Home键是绰绰有余的，如果用户想隐藏你的应用程序

Although the Home button is more than sufficient if a user wants to hide your app
