문제는 "지정된 자식에 이미 부모가 있으므로 먼저 해당 자식의 부모에 대해 removeView()를 호출해야합니다."

Question

늙어서 물어 봤기 때문에 죄송합니다. 하지만 모든 샘플을 시도했지만 모두 작동하지 않았습니다.

protected void onInitializeView() { 
    super.onInitializeView(); 
    // header text 
    TextView tvHeader = (TextView) findViewById(R.id.tvHeader); 
    tvHeader.setSelected(true); 
    tvHeader.setText(DataLocator.INSTANT.getCurrentCategory().getTitle()); 
    // set title 
    TextView tvTitle = (TextView) findViewById(R.id.tvTitle); 
    tvTitle.setText(article.getTitle()); 
    TextView tvDatetime = (TextView) findViewById(R.id.tvDatetime); 
    tvDatetime.setText(article.getDistributionDate()); 
    TextView tvShortContent = (TextView) findViewById(R.id.tvShortContent); 
    tvShortContent.setText(article.getShortContent()); 
    // setting web view 
    webView = (WebView) findViewById(R.id.webview); 
    webView.getSettings().setBuiltInZoomControls(true); 
    webView.getSettings().setJavaScriptEnabled(true); 
    webView.getSettings().setPluginsEnabled(true); 
    webView.setWebViewClient(new WebViewClient() { 
     @Override 
     public boolean shouldOverrideUrlLoading(WebView view, String url) { 
      OSUtil.gotoURL(getActivity(), url); 
      return true; 
     } 
    }); 
    webView.getSettings() 
      .setUserAgentString(
        "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/534.36 (KHTML, like Gecko) Chrome/13.0.766.0 Safari/534.36"); 

    webView.getSettings().setAllowFileAccess(true); 
    webView.getSettings().setLayoutAlgorithm(LayoutAlgorithm.SINGLE_COLUMN); 
    // get view 
    layoutReload = findViewById(R.id.layoutReload); 
    progressBar = findViewById(R.id.layoutProgress); 
    findViewById(R.id.btnShare).setOnClickListener(this); 
    findViewById(R.id.btnReload).setOnClickListener(this); 
    findViewById(R.id.btnBack).setOnClickListener(this); 
    loadContentArticle(); 
}

와 앱이 두 번째 시간을 볼 만들 때
그것은

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
     Bundle savedInstanceState) { 
    view = LayoutInflater.from(getActivity()).inflate(getContentView(), null, false); 
    onInitializeView(); 
    return view; 
} 

@Override 
public void onDestroyView() { 
    super.onDestroyView(); 
    if (view != null) { 
     ViewGroup parentViewGroup = (ViewGroup) view.getParent();

Answer 1

사용 removeAllViewsInLayout(); 대신 removeAllViews()

@Override 
public void onDestroyView() { 
    super.onDestroyView(); 
    if (view != null) { 
     ViewGroup parentViewGroup = (ViewGroup) view.getParent(); 
     if (parentViewGroup != null) { 
      parentViewGroup.removeAllViewsInLayout();; 
     } 
    } 
} 

내가하지 않도록 onDestroyView은()이 호출해야하는 유일한 장소입니다. 그러나보기를 parentViewGroup에 추가하기 전에 런타임 예외를 피하기 위해 parentViewGroup.removeAllViewsInLayout();;으로 전화하는 것이 좋습니다.
