{ 

    ...

    mToast = Toast.makeText(this, "null", Toast.LENGTH_SHORT); 

    ...

}

 

 

mToast 사용.

Func()

{

    mToast.setText(“show this text”); 

    mToast.show(); 

}

 

 

// 다른 클래스 ..모듈등에서 사용하기 편하게 유틸리티 클래스 생성후 사용해도 무방하다.

 



class appGlobalUtil 

{ 

    public static Toast mToast; 

 

    public  toast_message(  message)

    {

        mToast.setText(message); 

        mToast.show(); 

    }
