프래그먼트 다이얼로그를 생성하고
그안에 있는 텍스트뷰를 상황에따라 바꾸고 싶어 아래와 같이 코드를 구성하였습니다.
package com.zettamedia.kivi.FragmentDialog;

public static final int THREE_EXTEND_TYPE = 0x0003;
private Button mConfirmButton, mCancleButton, mExtendButton1;
private TextView mTitleTextView, mDescriptionTextView, mSubDescriptionTextView;
private int mType;
private OnDialogFragmentCommonClickListener mCommonClickListener;
public DialogFragmentCommon(int buttonType) {
this.mType = buttonType;
}
@Override
public void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater,
@Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
// TODO Auto-generated method stub
getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE);
getDialog().getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
//getDialog().getWindow().clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND); //화면어두워지게 하는거 막는 로직
View view = inflater.inflate(R.layout.dialog_fragment_common, container);
mTitleTextView = (TextView)view.findViewById(R.id.dialog_common_title_textView);
mDescriptionTextView = (TextView)view.findViewById(R.id.dialog_common_description_textView);
mSubDescriptionTextView = (TextView)view.findViewById(R.id.dialog_common_subDescription_textView);
mConfirmButton = (Button)view.findViewById(R.id.dialog_common_Button1);
mCancleButton = (Button)view.findViewById(R.id.dialog_common_Button2);
mExtendButton1 = (Button)view.findViewById(R.id.dialog_common_Button3);
switch(mType) {
case NONE_TYPE :
mConfirmButton.setVisibility(View.GONE);

break;

mConfirmButton.setVisibility(View.GONE);
mExtendButton1.setVisibility(View.GONE);
break;
case THREE_EXTEND_TYPE :
mConfirmButton.setVisibility(View.VISIBLE);
mCancleButton.setVisibility(View.VISIBLE);
mExtendButton1.setVisibility(View.VISIBLE);
break;
}
return view;
}
@Override
public void onActivityCreated(Bundle arg0) {
// TODO Auto-generated method stub
super.onActivityCreated(arg0);
mConfirmButton.setVisibility(View.VISIBLE);
mConfirmButton.setText("확인");
mTitleTextView.setText("기본 텍스트");
mDescriptionTextView.setText("기본 텍스트");
mConfirmButton.setOnClickListener(onClickListener);
mCancleButton.setOnClickListener(onClickListener);
mExtendButton1.setOnClickListener(onClickListener);
}
View.OnClickListener onClickListener = new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
if(mCommonClickListener != null) {
mCommonClickListener.onDialogFragmentCommonClickListener(v);
}else {
Log.i("CommonDialog Listener", "Listener is null");
}
}
};
//문제의 부분
public void setTitle(String title) {
this.mTitleTextView.setText(title);
}
public void setDescription(String desc) {
this.mDescriptionTextView.setText(desc);
this.mSubDescriptionTextView.setVisibility(View.GONE);
}
public void setSubDescription(String subDesc) {
this.mSubDescriptionTextView.setText(subDesc);
this.mSubDescriptionTextView.setVisibility(View.VISIBLE);
}
public void setOnCommonClickListener(OnDialogFragmentCommonClickListener listener) {
this.mCommonClickListener = listener;
}
}
위와 같이 공통다이얼로그프래그먼트 클래스를 만들었고
외부에서 경우에따라 텍스트뷰 몇개를 바꾸려고 하였습니다.
alertDialog.setTitle("알림");
alertDialog.setDescription("한번에 최대 100개까지 선택 가능합니다.");
alertDialog.show(fm, "contents_limit_selected_dialog");
사용할때 위와같이 사용하였는데 널포인터익셉션이 걸려버리네요ㅠㅠ
제가 뭘 잘못한걸까요?
