下划线写完不能显示，而且软件开始一直闪退，请问怎么解决

跟着写到这里的时候，line显示不出来。重新启动app后开始打不开，一直闪退，显示XXXmusicDemo keeps stopping或者 XXXmusicDemo has stopped。重启和清除缓存都不行。

这是logcat：

    <View style="@style/line" />
 view中的“V”是大写的V
 亲测改完之后可以运行

             public void run() {
//                Log.e("WelcomeActivity", "当前线程为："+ Thread.currentThread());
//                toMain();
                toLogin();
            }
        }, 3000);

    你的闪退是不是welcomeActivity里面的toMain忘了注释掉了，我的就是，找了好半天
