帮我。我试图在 android 中显示我的 html 页面。但它显示错误。

我在xml中的代码，

    <WebView
    android:id="@+id/webview"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:scrollbars="vertical" />

就像在java中一样；

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    WebView wv;  
    wv = (WebView) findViewById(R.id.webview);  
    wv.loadUrl("file:///android_asset/chapter1.html");  
}

}

但是，在运行应用程序时......它显示了很多错误，如下所示；

你的权利。当我检查时，此代码对我有用。更好的是，您再次使用此代码进行调试，方法是替换下面的代码。（没有更多的修改）

您的 JAVA 文件：

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.webkit.WebView;

public class Webview extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_webview);
        WebView wv;  
        wv = (WebView) findViewById(R.id.webview);  
        wv.loadUrl("file:///android_asset/chapter1.html");  
    }   
}

您的 XML 代码：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".Webview" >

<WebView android:layout_width="match_parent" 
  android:layout_height="match_parent" 
  android:id="@+id/webview">
 </WebView>

</RelativeLayout>

我也遇到了同样的问题，所以我将该文件从资产复制到了 SD 卡。它解决了我的问题。如果可能的话，看一下 AssetManager 类

private void copyAssets() {
    AssetManager assetManager = getAssets();
    String[] files = null;
    try {
        files = assetManager.list("");
    } catch (IOException e) {
        Log.e("tag", "Failed to get asset file list.", e);
    }
    for (String filename : files) {
        InputStream in = null;
        OutputStream out = null;
        try {
            in = assetManager.open(filename);
            File f = new File(Controller.getController()
                    .getApplicationBasePath() + "/Document_Directory");
            if (f.exists()) {
                out = new FileOutputStream(Controller.getController()
                        .getApplicationBasePath()
                        + "/Document_Directory/"
                        + filename);

                copyFile(in, out);
                in.close();
                in = null;
                out.flush();
                out.close();
                out = null;
            } else {
                f.mkdir();
                copyAssets();
            }
        } catch (IOException e) {
            Log.e("tag", "Failed to copy asset file: " + filename, e);
        }
    }
}
