的Android的WebView不渲染HTML內容正確

我完全不知道這是否是做了正確的方式，但只要我正在顯示啓動畫面作爲web視圖加載，當web視圖加載完成，我顯示的WebView 。的Android的WebView不渲染HTML內容正確

但WebView中的HTML內容沒有被正確地渲染。它在我的Android手機的內置瀏覽器以及我擁有的其他所有設備上正確顯示內容。所以這個問題僅限於這個應用程序。

MainActivity.java

package dk.zerone.vuc; 

import android.net.ConnectivityManager; 
import android.net.NetworkInfo; 
import android.os.Bundle; 
import android.app.Activity; 
import android.app.AlertDialog; 
import android.content.Context; 
import android.content.DialogInterface; 
import android.graphics.Color; 
import android.util.Log; 
import android.view.Menu; 
import android.view.View; 
import android.webkit.WebView; 
import android.webkit.WebViewClient; 

public class MainActivity extends Activity { 

public final boolean networkCheck() { 
    ConnectivityManager connec = (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE); 

    if (connec.getNetworkInfo(0).getState() == NetworkInfo.State.CONNECTED || 
    connec.getNetworkInfo(0).getState() == NetworkInfo.State.CONNECTING || 
    connec.getNetworkInfo(1).getState() == NetworkInfo.State.CONNECTING || 
    connec.getNetworkInfo(1).getState() == NetworkInfo.State.CONNECTED) { 
     return true; 
    } else if (connec.getNetworkInfo(0).getState() == NetworkInfo.State.DISCONNECTED || connec.getNetworkInfo(1).getState() == NetworkInfo.State.DISCONNECTED ) { 
     return false; 
    } 
    return false; 
} 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    /* Splash screen */ 
    setContentView(R.layout.splash); 

    if(networkCheck()) { 

     String url = "http://mobil.vucfyn.dk/mobil"; 

     final WebView webview; 
     webview = new WebView(MainActivity.this); 
     webview.loadUrl(url); 

     webview.setWebViewClient(new WebViewClient() { 
      @Override 
      public boolean shouldOverrideUrlLoading(WebView view, String url) { 
       //view.loadUrl(url); 
       return false; 
      } 

      @Override 
      public void onPageFinished(WebView view, String url) { 
       super.onPageFinished(view, url); 
       setContentView(webview); 

      } 
     }); 

    } else { 
     AlertDialog alertDialog = new AlertDialog.Builder(MainActivity.this).create(); 
     alertDialog.setTitle("Fejl"); 
     alertDialog.setMessage("Ingen forbindelse til internettet"); 

     alertDialog.setButton("OK", new DialogInterface.OnClickListener() { 
      public void onClick(DialogInterface dialog, int which) { 

      } 
     }); 
     alertDialog.show(); 
    } 
    } 

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    getMenuInflater().inflate(R.menu.activity_main, menu); 
    return true; 
    } 
}

logcat的輸出：

你使用webview.loadUrl（url）兩次的任何原因？ –

不，不是，只是試圖找出問題所在。我已經updatet上面的代碼，我已經commentet了'使用loadURL（URL）''中shouldOverrideUrlLoading（）'web視圖仍然無法正確顯示HTML內容。任何幫助是極大的讚賞。 :) – user1599309

如果網站的JavaScript你缺少這一行：

webView.getSettings().setJavaScriptEnabled(true);

如果你的目標是高於2.3 .3嘗試在你的清單文件中添加這個。

android:hardwareAccelerated="true"

非常感謝你，我不知道默認情況下沒有啓用JavaScript。 – user1599309

歡迎您。人們往往會忘記它，假設它在android中默認啓用。 –
