推荐答案

你可以这样做：

说活动A是要推出仅在第一次活动，和b活动，该系统将在第一时间后启动的活动。

Say Activity A is the activity that you want to launch only the first time, and activity B the activity that the system will launch after the first time.

在你舱单，把b活动作为你的发射活动。然后活动的OnCreate或更好OnResume内b将以下内容：

In you manifest put Activity B as your launcher activity. Then inside the oncreate or better OnResume of activity B put the following:

    @Override
protected void onResume() {
    super.onResume();

       if(firstLaunch()){
           startActivity(new Intent(this, A.class));
           finish();
       }else{
         //Do your normal stuff
       }

    }


    private boolean firstLaunch(){
         SharedPreferences prefs = getSharedPreferences(
            "Preferences",
            Context.MODE_PRIVATE);
         return prefs.getBoolean("firstLaunch",false);
    }

然后在你的一个活动，一定要在你的preferences设置一个标志，表明您的应用程序已经运行超过一次。所以某处活性的把这样的：

Then on your A activity be sure to set a flag on your preferences to indicate that your application has run more than once. So somewhere inside activity A put this:

   private void setFirsLaunchFlag(){
         SharedPreferences prefs = getSharedPreferences(
            "Preferences",
            Context.MODE_PRIVATE);
         SharedPreferences.Editor edit = prefs.edit();
         edit.putBoolean("firstLaunch",true);
         edit.commit();
   }
