onKeyDown 대화 상자가 표시되지 않습니다.

내 앱에서 onKeyDown 메서드를 무시하고 사용자 지정 대화 상자를 호출했지만 장치를 실행 중일 때 해당 사용자 지정 대화 상자가 표시되지 않았습니다. 디버거를 사용하여 onKeyDown 메서드가 호출되었지만 대화 상자가 표시되지 않고 앱이 종료되는 것을 확인했습니다. 도와주세요onKeyDown 대화 상자가 표시되지 않습니다.

이 내 onKeyDown 방법,

@Override 
public boolean onKeyDown(int keyCode, KeyEvent event) 
{ 
    if ((keyCode == KeyEvent.KEYCODE_BACK)) 
    { 
     LayoutInflater factory = LayoutInflater.from(FirstScreenActivity.this); 

     View DialogView = factory.inflate(R.layout.exit_dialog, null); 

     final Dialog exit_dialog = new Dialog(FirstScreenActivity.this,R.style.Theme_Dialog); 
     exit_dialog.setContentView(DialogView); 
     exit_dialog.show(); 
     Button btnYes = (Button) exit_dialog.findViewById(R.id.btnYes); 
     btnYes.setOnClickListener(new View.OnClickListener() 
     { 

      @Override 
      public void onClick(View v) 
      { 
       android.os.Process.killProcess(android.os.Process.myPid()); 
      } 
     }); 
     Button btnNo = (Button) exit_dialog.findViewById(R.id.btnNo); 
     btnNo.setOnClickListener(new View.OnClickListener() 
     { 

      @Override 
      public void onClick(View v) 
      { 
       exit_dialog.dismiss(); 
      } 
     }); 
    } 
    return super.onKeyDown(keyCode, event); 
}

또한 로그 캣에서이 오류가.

감사합니다.

Dialog이 표시되면 Activity이 완료됩니다.

이 라인은 Dialog 창을 누설에 이르게 당신은 Dialog 표시되는 시간에 활동을

return super.onKeyDown(keyCode, event);

을 완료 리드.

변경

return false;

otherise overeride onBackpressed()이 논리를 쓰기에이 라인

return super.onKeyDown(keyCode, event);
