Question

是否可以从非活动类创建通知？如果是这样，怎么样？

Answer 1

将上下文传递给类，然后正常创建

Answer 2

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


}

其他班级

class B{

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

Answer 3

正如上面提到的subspider，将上下文传递给类，你会没事的：

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
       */
    }
}
