從非活動類創建通知

Question

是否可以從非活動類創建通知？ 如果是這樣，怎么辦？

Answer 1

將上下文傳遞給類，然后正常創建它

Answer 2

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


} 

其他班級

class B{

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

Answer 3

正如上面的子蜘蛛所說，將上下文傳遞給類，您會沒事的：

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
       */
    }
}
