详解AndroidWebView加载html片段-创新互联

这里我先简单描述一下需求：服务器返回的是html页面的一部分带有标签的内容。

解决的思路是：将服务器返回的内容片段拼凑成一个完整的页面。

下面直接上核心代码：

这里是WebView一些配置

WebSettings settings = webView.getSettings();
settings.setJavaScriptEnabled(true);
settings.setDomStorageEnabled(true);
settings.setUseWideViewPort(true);
settings.setLoadWithOverviewMode(true);
webView.setWebViewClient(new MyWebViewClient(activity));
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {     
 settings.setLayoutAlgorithm(WebSettings.LayoutAlgorithm.TEXT_AUTOSIZING);
} else {
 settings.setLayoutAlgorithm(WebSettings.LayoutAlgorithm.NORMAL);
}
webView.loadData(getHtmlData(item.content), "text/html;charset=utf-8","utf-8");
private String getHtmlData(String bodyHTML) {
    String head = "" +
        " " +
        "" +
        "";
    return "" + head + "" + bodyHTML + "";
  }

static class MyWebViewClient extends WebViewClient{
    private WaitingDialog dialog;
    private Activity activity;
    public MyWebViewClient(Activity activity){
      dialog = new WaitingDialog(activity);
      this.activity = activity;
    }

    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
      LogUtil.e(url);
      view.loadUrl(url);
      return true;
    }

    @Override
    public void onPageStarted(WebView view, String url, Bitmap favicon) {
      super.onPageStarted(view, url, favicon);
      if(!activity.isFinishing()) dialog.show();
    }

    @Override
    public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {
      handler.proceed();
      super.onReceivedSslError(view, handler, error);
    }

    @Override
    public void onPageFinished(WebView view, String url) {
      super.onPageFinished(view, url);
      if(!activity.isFinishing()) dialog.dismiss();
    }
