Question

我一直在寻找这个问题的答案大约4个小时而且很痛苦，到目前为止，我已经遇到了多个关于如何摆脱实际错误的修复，我已经阅读了以前的近两整页海报LNK2019＆amp; LNK1120错误，我仍然不明白修复程序到目前为止如何工作，我没有包括任何外部库。我试图找到我正在寻找的东西，但说实话我不明白我在寻找什么，因为我没有实现外部API或任何类型的东西，好吧，我不相信，这是我的朋友代码，所以我不知道他实现了什么，请帮助，也是，这里也是源代码。

错误LNK2019未解析的外部符号“void __cdecl displaySpace（int，class＆gt; std :: basic_string，class std :: allocator＆gt;，bool，char）“（？displaySpace @@ YAXHV？$ basic_string @ DU？ $ char_traits @ D @ std @@ V？$ allocator @ D @ 2 @@ std @@ _ ND @ Z）在函数_main中引用

（它也说它在第1行）

您在函数原型（和调用站点）之间存在不匹配：

@Bind(R.id.webView)
WebView webView;
private String iteamRichText;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_web_view);
    ButterKnife.bind(this);
    final Intent mIntent = getIntent();
    iteamRichText = mIntent.getExtras().getString(getResources().getString(R.string.putkey_iteam_richText));
    webView.setWebViewClient(new MyBrowser());

   // webView.getSettings().setLoadsImagesAutomatically(true);

    webView.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
    webView.getSettings().setBuiltInZoomControls(true);
    webView.getSettings().setLoadWithOverviewMode(true);
   // webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
    webView.getSettings().setJavaScriptEnabled(true);
    webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(false);
    webView.getSettings().setSupportMultipleWindows(false);
    webView.getSettings().setUseWideViewPort(false);
    webView.setScrollbarFadingEnabled(true);

    webView.setFocusableInTouchMode(false);
    webView.setFocusable(false);
    webView.loadData(iteamRichText, "text/html", "UTF-8");
}

private class MyBrowser extends WebViewClient {
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        //view.loadData(iteamRichText, "text/html", "UTF-8");
        view.loadUrl(url);
        Log.e("process", "" + url);

        if(url.startsWith("http") && (url.contains(".jpg") || url.contains(".png") || url.contains(".jpeg") || url.contains(".gif")))
        {
            Intent mIntent = new Intent(WebViewActivity.this, FullScreenImgActivity.class);
            mIntent.putExtra(getResources().getString(R.string.putkey_webViewfullImagePath), url);
            startActivity(mIntent);
        }
        return true;
    }

}

和实际的功能定义：

void displaySpace(int wordLength, string userWord, bool correctGuess, char guessChar);

这就是编译器无法找到匹配函数的原因。
