Question

我在android中集成html。我创建了一个Web视图，但我无法加载本地html页面。令人惊讶的是，网页视图正在加载'http：google.com'，而不是我的本地html文件。我已经尝试了几乎所有可能的SO链接。错误消息是“无法加载网页”

WebView view  =  (WebView) findViewById(R.id.webView1);
    view.loadUrl("file:///assets/www/trialhtml.html");![enter image description here][1]

Answer 1

创建你的html并将它放到assets文件夹，然后你需要这样的

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    WebView webView = new WebView(this);
    webView.loadUrl("file:///android_asset/test.html");
    setContentView(webView);
}

这是结果 enter image description here

Answer 2

尝试以下代码： -

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    String myURL = "file:///android_asset/index.html";
    WebView view  =  (WebView) findViewById(R.id.webView1);

    /*By default Javascript is turned off,
     * it can be enabled by this line.
     */
    view.getSettings().setJavaScriptEnabled(true);
    view.setWebViewClient(new WebViewClient());

    view.loadUrl(myURL);

}

检查您的文件是否存在，您也可以清理项目并重建它。

尝试使用此代码：

this.webview = (WebView)findViewById(R.string.webview);

    WebSettings settings = webview.getSettings();
    settings.setJavaScriptEnabled(true);
    webview.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);

    final AlertDialog alertDialog = new AlertDialog.Builder(this).create();

    progressBar = ProgressDialog.show(Main.this, "WebView Example", "Loading...");

    webview.setWebViewClient(new WebViewClient() {
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            Log.i(TAG, "Processing webview url click...");
            view.loadUrl(url);
            return true;
        }

        public void onPageFinished(WebView view, String url) {
            Log.i(TAG, "Finished loading URL: " +url);
            if (progressBar.isShowing()) {
                progressBar.dismiss();
            }
        }

        public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
            Log.e(TAG, "Error: " + description);
            Toast.makeText(activity, "Oh no! " + description, Toast.LENGTH_SHORT).show();
            alertDialog.setTitle("Error");
            alertDialog.setMessage(description);
            alertDialog.setButton("OK", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int which) {
                    return;
                }
            });
            alertDialog.show();
        }
    });
    webview.loadUrl("http://www.google.com");

Answer 4

将.html文件粘贴到项目文件夹的assets文件夹中。并在布局文件夹中使用fol代码

创建一个xml文件

WebView  xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/webview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>

在活动中添加fol代码

setContentView(R.layout.my);
WebView mWebView = null;
mWebView = (WebView) findViewById(R.id.webview);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.loadUrl("file:///android_asset/www/trialhtml.html"); //new.html is html file na

Web视图未在android中加载本地html文件
