你可以通过在AndroidManifest.xml文件中的相关<activity>条目中将android:noHistory属性设置为“true”来实现这一点。例如:

<activity
    android:name=".AnyActivity"
    android:noHistory="true" />

if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            super.finishAndRemoveTask();
        }
        else {
            super.finish();
        }

是的，看看Intent.FLAG_ACTIVITY_NO_HISTORY。

居然没有人提到这个优雅的解决方案，真是不可思议。这应该是公认的答案。

SplashActivity -> AuthActivity -> DashActivity

if (!sessionManager.isLoggedIn()) {
    Intent intent = new Intent(context, AuthActivity.class);
    intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
    context.startActivity(intent);
    finish();
} else {
   Intent intent = new Intent(context, DashActivity.class);
   context.startActivity(intent);
    finish();
}

这里的关键是使用intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);为中介活动。一旦中间的链接断开，DashActivity将位于堆栈的第一个和最后一个。

android:noHistory="true"是一个糟糕的解决方案，因为它会在依赖Activity作为回调时引起问题，例如onActivityResult。这是推荐的解决方案，应该被接受。

I know I'm late on this (it's been two years since the question was asked) but I accomplished this by intercepting the back button press. Rather than checking for specific activities, I just look at the count and if it's less than 3 it simply sends the app to the back (pausing the app and returning the user to whatever was running before launch). I check for less than three because I only have one intro screen. Also, I check the count because my app allows the user to navigate back to the home screen through the menu, so this allows them to back up through other screens like normal if there are activities other than the intro screen on the stack.

//We want the home screen to behave like the bottom of the activity stack so we do not return to the initial screen
//unless the application has been killed. Users can toggle the session mode with a menu item at all other times.
@Override
public void onBackPressed() {
    //Check the activity stack and see if it's more than two deep (initial screen and home screen)
    //If it's more than two deep, then let the app proccess the press
    ActivityManager am = (ActivityManager)this.getSystemService(Activity.ACTIVITY_SERVICE);
    List<RunningTaskInfo> tasks = am.getRunningTasks(3); //3 because we have to give it something. This is an arbitrary number
    int activityCount = tasks.get(0).numActivities;

    if (activityCount < 3)
    {
        moveTaskToBack(true);
    }
    else
    {
        super.onBackPressed();
    }
}

在清单中，您可以添加:

android:noHistory="true"

<activity
android:name=".ActivityName"
android:noHistory="true" />

你也可以打电话

finish()

在调用startActivity(..)
