The constructor Intent(new View.OnClickListener(){}, Class<ButtonStudyActivity>) is undefined

对于错误The constructor Intent(new View.OnClickListener(){}, Class<ButtonStudyActivity>) is undefined解决办法：

首先源码：

[java]

Notification notification = new Notification(R.drawable.ic_launcher,"" + BMI,System.currentTimeMillis() );

PendingIntent contentIndent = PendingIntent.getActivity(this, 0, new Intent(this,MainActivity.class), PendingIntent.FLAG_UPDATE_CURRENT);

notificationManager.notify(0,notification);

或者是

[java]

Intent intent = new Intent(this, ButtonStudyActivity.class);

这里的this，在匿名类中通常是指的是这个匿名类，而不是activity，在indent中需要的是当前activity，所以修改后的代码应该是

[java]

Intent intent = new Intent(MainActivity.this,MainActivity.class)

就可以解决
