活动未开始;另一项活动正在开始

我面临一个非常奇怪的问题。我正在尝试启动一项活动，但不是那样，另一项活动正在开放。我正在尝试打开RegActivity，我确实在mainfiest中指定了它并且还使它成为Launcher活动但是当我运行应用程序时“MainActivity”正在调用。 MainActivity甚至不是Launcher或Default活动。我清理了项目，重建了它。但是，仍然没有任何作用。我被卡住了。我浪费了我的一整天，没有任何帮助我。请帮助伙计!!! 停止低估它。如果你不知道答案，那就离开吧。

请告诉我这里有什么问题？我找不到任何东西。

答案 0 :(得分：1)

你的onCreate（）

中的代码怎么样？ 
if(preferenceHelper.getIsLogin()){
            Intent intent = new Intent(RegActivity.this,MainActivity.class);
            intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK);
            startActivity(intent);
            this.finish();
        }

如果preferenceHelper.getIsLogin()为真，您将无法看到您的RegActivity，因为它会立即启动MainActivity。
