android: WebView, отображать содержимое html из папки с ресурсами

Question

Помогите мне. Я пытался отобразить мою html-страницу в Android. Но это показывает ошибку.

Мой код в XML,

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

Как и в Java;

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"); 
} 

}

Но, в то время как запустить приложение ... он показывает много ошибок следующим образом;

Answer 1

Ваше право. Этот код работает для меня, когда я проверил. Лучше, вы снова выполните Debug с этим кодом, заменив этот ниже код. (NO MORE МОДИФИКАЦИИ)

ВАШ JAVA FILE:

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"); 
    } 
} 

ВАШ XML КОД:

<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> 

Answer 2

У меня также была такая же проблема, поэтому я скопировал этот файл из актива в SDCard. он решил мою проблему. взглянуть на класс AssetManager один раз, если это возможно

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); 
     } 
    } 
}
