当你打电话给你写的家庭活动时
Intent intent = new Intent(getApplicationContext(), Home.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);
其他明智的用途，你使用finish（）;在哪里使用
System.exit(1);
完成申请
答案 1 :(得分：0)
您可以在活动代码
中的清单文件中尝试此nohistory属性android:noHistory="true"
<activity
android:name=".Homeactivity"
android:label=""
android:noHistory="true">
</activity>
<强>（或）
然后onbackpress函数指定以下命令
Intent a = new Intent(Intent.ACTION_MAIN);
a.addCategory(Intent.CATEGORY_HOME);
a.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
a.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(a);
finish();
<强>（或）
如果您非常需要退出，请使用System.exit(0)但强烈不推荐，并且通常会说您有应用程序的架构问题。
