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] 

new Intent(MainActivity.this,MainActivity.class)
