从非活动类创建通知

Question

是否可以从非活动类创建通知？如果是这样，怎么样？

Answer 1

通过上下文中的类，然后创建它通常

Answer 2

class A extends Activity{ 
//required stuff go here 
new B().createDialog(A.this); 


} 

其他类

class B{ 

public void createDialog(Context context){ 
//create your dialog or notification here 
} 
} 

Answer 3

正如subspider上面所说的，通过上下文到类，你会被罚款：

public class DoSomethingClass { 

    //Here's a context 
    private Context _CONTEXT; 

    //Construct that sets the context 
    public DoSomethingClass(Context c) { 
     this._CONTEXT = c; 
    } 

    public void createNotification() { 

     /* 
      Create the notification as usual, just make sure you alter the following lines: 

      Intent notificationIntent = new Intent(this, MyClass.class); 
      Context context = this.getApplicationContext(); 

      ^Make sure you alter this into this._CONTEXT above 
     */ 
    } 
}
