我正在使用导航滑块菜单制作应用程序。我之前没有用过它，所以我无法弄清楚问题。我使用了http://developer.android.com/training/implementing-navigation/nav-drawer.html给出的导航菜单代码。但我没有使用碎片。相反，我正在使用个人活动。这是主要活动。

答案 0 :(得分：1)
在最后调用的onCreate（..）方法中：
selectItem(0);
在您的selectItem（int position）方法中，您将启动Main活动：
case 0:
i= new Intent(this,Main.class)
break;
.....
startActivity(i);
所以不知何故，你创造了一个无限循环，这就是为什么你的手机抱怨很多工作。

每当你看到这个时，请认为问题是你在UI线程中做了很多工作（你应该使用Handler / Asynctask / Thread）或者在这种情况下你有一个无限循环。
