我正在使用 webview 在 android 上加载数据。它加载得很好，但是当我触摸 webview 时，它会使应用程序崩溃并显示以下错误消息。我在 android 4.2 中遇到了这个问题，你们能告诉我为什么会这样吗.

我正在通过愚蠢的代码加载 webview

<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="match_parent"
  android:layout_height="match_parent">
    <WebView android:id="@+id/webView1" android:layout_width="match_parent" android:layout_height="match_parent"></WebView>
</LinearLayout>

这是代码，

WebView w=(WebView)findViewById(R.id.webView1);
w.loadDataWithBaseURL("http://www.mobilea.pcma.org/mobile/xml/sisap.asp?sid="+str+"&pn=AboutUs", Hold,"text/html", "utf-8",null);

异常详情：

尝试使用 loadUrl

WebView w=(WebView)findViewById(R.id.webView1);
w.loadUrl("http://www.mobilea.pcma.org/mobile/xml/sisap.asp?sid="+str+"&pn=AboutUs");

试试这个 webview 的代码。它适用于所有版本的android。将您使用的所有图像文件复制并粘贴到项目的“res”文件夹中的所有“drawable”文件夹中。一切顺利..

MainActivity.java:



package com.example.yourappname;

import android.app.Activity;
import android.app.AlertDialog;
import android.content.DialogInterface;
import android.content.Intent;
import android.content.res.Configuration;
import android.graphics.Bitmap;
import android.net.Uri;
import android.os.Bundle;
import android.view.KeyEvent;
import android.view.View;
import android.webkit.ValueCallback;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.webkit.WebChromeClient;
import android.widget.Button;
import android.widget.EditText;

public class MainActivity extends Activity {

WebView web;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    web = (WebView) findViewById(R.id.webView1);
    web = new WebView(this);  
    web.getSettings().setJavaScriptEnabled(true);
  
     //change the url below to the url you need
  
    web.loadUrl("http://www.xyxyxyxyxyxy.com");
    web.setWebViewClient(new myWebClient());
    web.setWebChromeClient(new WebChromeClient());
    setContentView(web);
}



public class myWebClient extends WebViewClient
{
    @Override
    public void onPageStarted(WebView view, String url, Bitmap favicon) {
        // TODO Auto-generated method stub
        super.onPageStarted(view, url, favicon);
    }

    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        // TODO Auto-generated method stub

        view.loadUrl(url);
        return true;

    }
    
    @Override
    public void onPageFinished(WebView view, String url) {
        // TODO Auto-generated method stub
        super.onPageFinished(view, url);

        
    }
}

//flip screen not loading again
@Override
public void onConfigurationChanged(Configuration newConfig){        
  super.onConfigurationChanged(newConfig);
}



@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if(event.getAction() == KeyEvent.ACTION_DOWN){
        switch(keyCode)
        {
        case KeyEvent.KEYCODE_BACK:
            if(web.canGoBack()){
             	web.goBack();
             }
            else
            {
            	backButtonHandler();
            }
            return true;
        }

     }
     return super.onKeyDown(keyCode, event);
 }
public void backButtonHandler() {
		AlertDialog.Builder alertDialog = new AlertDialog.Builder(
				MainActivity.this);
		
	
		// Setting Dialog Title
	   // Setting Dialog Message
      // You can delete the next 2 lines if you wish
		
		alertDialog.setTitle("");
		alertDialog.setIcon(R.drawable.dialog_icon);
		alertDialog.setMessage("Exit Now?");
		
	     // Setting Icon to Dialog
		// Setting Positive "Yes" Button
		
		alertDialog.setPositiveButton("Exit",
				new DialogInterface.OnClickListener() {
					public void onClick(DialogInterface dialog, int which) {
						finish();
					}
		});
		
	// Setting Negative "NO" Button
		
		alertDialog.setNegativeButton("No",
				new DialogInterface.OnClickListener() {
					public void onClick(DialogInterface dialog, int which) {
						// Write your code here to invoke NO event
						dialog.cancel();
					}
				});
	// Showing Alert Message
		alertDialog.show();
}
