WebView 出现问题，卡在加载中答案

【问题标题】：Problem with WebView, gets stuck in loadingWebView 出现问题，卡在加载中
【发布时间】：2020-05-23 06:28:40
【问题描述】：

我遇到了一个问题，我的页面卡在加载页面中，只是那个页面，我认为是因为它没有启用 javascript，然后添加它并添加了一堆其他代码，我可能不会需要，但它被丢弃了。

知道这会是什么问题吗？

import android.content.pm.ActivityInfo;
import android.os.Build;
import android.os.Bundle;

import com.google.android.material.floatingactionbutton.FloatingActionButton;
import com.google.android.material.snackbar.Snackbar;

import androidx.appcompat.app.AppCompatActivity;
import androidx.appcompat.widget.Toolbar;

import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

//Obtain the WebSettings object//
    WebSettings webSettings = browser.getSettings();

    browser.setWebChromeClient(new WebChromeClient() {
        public void onGeolocationPermissionsShowPrompt(String origin, GeolocationPermissions.Callback callback) {
            // callback.invoke(String origin, boolean allow, boolean remember);
            callback.invoke(origin, true, false);
                                   }

                               });



browser.getSettings().setUseWideViewPort(true);
        browser.getSettings().setLoadWithOverviewMode(true);
        browser.getSettings().setDomStorageEnabled(true);
        browser.clearView();
        browser.setHorizontalScrollBarEnabled(false);
        browser.getSettings().setAppCacheEnabled(true);
        browser.getSettings().setDatabaseEnabled(true);
        if (Build.VERSION.SDK_INT < Build.VERSION_CODES.KITKAT) {
            browser.getSettings().setDatabasePath("/data/data/" + this.getPackageName() + "/databases/");
        }
        browser.setVerticalScrollBarEnabled(false);
        browser.getSettings().setBuiltInZoomControls(true);
        browser.getSettings().setDisplayZoomControls(false);
        browser.getSettings().setAllowFileAccess(true);
        browser.getSettings().setPluginState(WebSettings.PluginState.OFF);
        browser.setScrollbarFadingEnabled(false);
        browser.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);
        browser.getSettings().setDefaultZoom(WebSettings.ZoomDensity.FAR);
        browser.setWebViewClient(new WebViewClient());
        browser.getSettings().setRenderPriority(WebSettings.RenderPriority.HIGH);
        browser.setInitialScale(1);


    browser.loadUrl("https://s167-es.ogame.gameforge.com/game/index.php?page=ingame&component=overview");
    Toast.makeText(this, "Loading... Wait, please...",
            Toast.LENGTH_LONG).show();
    browser.setWebViewClient(new WebViewClient() {
        // evita que los enlaces se abran fuera nuestra app en el navegador de android
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            return false;
        }

    });
}

}

然后在普通浏览器中应该会打开一个带有游戏的新标签页，它也使用 javascript 以防万一它很重要。

这是上一张图片中的源代码视图：（在 google chrome 中，但我的观点是，您可能会找到一些可以帮助您确定我在 webview 中是否缺少某些代码的东西什么的。

标签： javascript php android android-studio webview

【解决方案1】：

我认为问题与使用 JavaScript 完全动态创建的 URL 上的内容有关（如您在 HTML 源代码中所见），并且您尚未在 WebSettings 中启用 JavaScript。

还有其他一些事情正在发生使您的代码难以阅读。

你有这行：

WebSettings webSettings = browser.getSettings();

但是你这样做：

browser.getSettings().setUseWideViewPort(true);

可以写成：

webSettings.setUseWideViewPort(true);

至于这个问题，我相信下面这行可以解决加载问题：

webSettings.setJavaScriptEnabled(true);

就个人而言，我还会包括：

webSettings.setLoadsImagesAutomatically(true);

【讨论】：

嘿，谢谢你的建议。关于这个问题，它仍然有同样的问题。是的，我相信就像你说的那样，如果你的意思是它在“点击正确的”之前通过一些 URL 重定向你。我认为问题在于大厅，因为您无法像以前那样直接登录游戏。游戏让你登录，然后即使你已经登录游戏，你也会被重定向到大厅，然后你需要按 PLAY 或“Jugar”才能转到我最初想去的链接。
我刚刚意识到它卡在这个链接中：lobby.ogame.gameforge.com/es_ES/loading 您实际上可以在链接中看到它就像一个循环，而它确实加载了它必须去的真实网络。但是问题在于它在加载后没有正确重定向，或者实际上并没有真正加载网站，所以它可能无法重定向。我认为它必须是这两个选项之一。
