android - 从 assets 文件夹加载本地 html 文件的问题

Question

我正在尝试从列表视图项目单击的资产文件夹中加载 html 文件。问题是，点击它会显示干净的页面，检查 html 文件。这是一段代码。

public static ListView listview;
    public static ArrayList<String> interviews;
    public static ArrayAdapter<String> adapter;
    public WebView myWebView;

    @Override
    protected void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_kochergin);
        listview = (ListView) findViewById(R.id.mainListView);
        myWebView = (WebView)findViewById(R.id.webview);
    //  myWebView = new WebView(this);
        listview.setBackgroundColor(Color.BLACK);
        listview.setCacheColorHint(Color.BLACK);

        String[] interviewlist = new String[] {"Interview1", "Interview2","Interview3","Interview4","Interview5","Interview6"};  
        ArrayList<String> interviews = new ArrayList<String>();
        interviews.addAll( Arrays.asList(interviewlist) );


        ArrayAdapter <String> adapter = new ArrayAdapter<String>(this, R.layout.simplerow, R.id.rowTextView, interviews);
        listview.setAdapter(adapter);
        Collections.sort(interviews);


    listview.setOnItemClickListener(new OnItemClickListener() 
    {
        @Override
        public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) 
        {

            setContentView(R.layout.webview);

        //  myWebView.setVisibility(View.VISIBLE);
           //   myWebView.getSettings().setJavaScriptEnabled(true);
            myWebView.loadUrl("file:///android_asset/2.html");
        }
    });

我做错了什么？

Answer 1

您正在加载其中的 URL，myWebView而R.layout.activity_kochergin不是R.layout.webview您设置为 Activity 的内容视图的 URL onItemClick。

所以删除setContentView(R.layout.webview);from onItemClick，它会工作。

更新

更改setOnItemClickListener为： -

listview.setOnItemClickListener(new OnItemClickListener() 
    {
        @Override
        public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) 
        {

            setContentView(R.layout.webview);
            myWebView = (WebView)findViewById(R.id.webview);
            myWebView.loadUrl("file:///android_asset/2.html");
        }
    });
