javascript - 如何使用 Android 搜索查询(从操作栏中的搜索框)加载最后带有查询的指定 URL？

Question

计算器溢出。我已经花了 13 个小时试图解决这个问题，我觉得自己还没有解决这个问题有点愚蠢。基本上我想要做的是从操作栏的搜索框中提取用户的搜索查询，并将该查询放在我指定的 URL 的末尾，然后将该 URL 加载到我当前的 web View 中。

例子:用户在 www.homepage.tld用户点击搜索框，输入狗。我想将他的查询 (dog) 放在 www.homepage.tld?search=(USER QUERY) 的末尾然后，我想将该 URL 加载到用户当前正在使用的同一 webview 中(基本上就像他单击链接一样)。

这是我当前的代码。它不理解 +QUERY(但我只是把它扔在那里希望它能工作:(

    public boolean onKeyEnter(int keyCode, KeyEvent event) {
        if ((keyCode == KeyEvent.KEYCODE_ENTER) && SearchView.QUERY) {
            webview.loadUrl("http://www.homepage.tld?s="+QUERY);
            return true;
        }

**此 log_tag 从不触发。前两个(0 和 1)在应用加载时触发。

final SearchView.OnQueryTextListener queryTextListener = new SearchView.OnQueryTextListener() {
    @Override
    public boolean onQueryTextChange(String newText) {
        // Do something
        return true;
    }

    @Override
    public boolean onQueryTextSubmit(String query) {
        // You can use the webview here.
        return true;
    }
};

searchView.setOnQueryTextListener(queryTextListener);
