android - 如何在 onitemclick 的 webview 中加载 HTML 文件

Question

我有超过 100 个 html 文件，我希望每个文件在 ListView 中的行点击打开，每个 html 文件应该在 webview 中打开，我试过这段代码但是这不起作用，只有 webview 在行点击打开， html 文件未显示。

 package com.Example.apk;



import android.app.Activity;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.webkit.WebViewClient;

public class WebView extends Activity {

public class WebViewActivity extends Activity {
    WebView web;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_webview);
        web = (WebView) findViewById(R.id.webview1);
        web.setWebViewClient(new myWebClient());
        web.getSettings().setJavaScriptEnabled(true);
        int pos = getIntent().getIntExtra("key",0);
        if(pos==0)
        {
        web.loadUrl("file:///android_asset/work.html");
        }
        else if(pos==1)
        {
        web.loadUrl("file:///android_asset/work1.html");
        }  
        else if(pos==2)
        {
        web.loadUrl("file:///android_asset/work2.html");
        } 
        else if(pos==3)
        {
        web.loadUrl("file:///android_asset/work3.html");
        }  
      // similarly for 4 and 5 and so on.
    }

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

        }
    }
}
}

Answer 1

将位置传递给下一个 Activity

list1.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
            int position, long id) {
Intent myIntent = new Intent(MainActivtiy.this,WebViewActivity.class);
myIntent.putExtra("key",position);
startActivity(myIntent);
}
});   

然后在WebViewActivity即activity_webview)

public class WebViewActivity extends Activity {
WebView web;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_webview);
    web = (WebView) findViewById(R.id.webview1);
    web.setWebViewClient(new myWebClient());
    web.getSettings().setJavaScriptEnabled(true);
    int pos = getIntent().getIntExtra("key",0);
    if(pos==0)
    {
    web.loadUrl("file:///android_asset/work.html");
    }
    else if(pos==1)
    {
    web.loadUrl("file:///android_asset/work1.html");
    }  
    else if(pos==2)
    {
    web.loadUrl("file:///android_asset/work2.html");
    } 
    else if(pos==3)
    {
    web.loadUrl("file:///android_asset/work3.html");
    }  
   ...// similarly for 4 and 5 and so on.
}

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

    }
}

WebViewActivity 的 xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >

<WebView
    android:id="@+id/webView1"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

</LinearLayout>

在 list 文件中为 WebViewActivity 创建一个条目。
