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 = "<head>" +
"<meta name=\"viewport\" content=\"width=device-width, initial-scale=1.0, user-scalable=no\"> " +
"<style>html{padding:15px;} body{word-wrap:break-word;font-size:13px;padding:0px;margin:0px} p{padding:0px;margin:0px;font-size:13px;color:#222222;line-height:1.3;} img{padding:0px,margin:0px;max-width:100%; width:auto; height:auto;}</style>" +
"</head>";
return "<html>" + head + "<body>" + bodyHTML + "</body></html>";
}
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();
}
笔者在Nexus6 7.0上面测试偶尔出现，html内容无法加载出来，显示一片空白，开启硬件加速后完美解决。
在上面WebView设置的部分加上如下代码
if (webView.isHardwareAccelerated()) webView.setLayerType(View.LAYER_TYPE_HARDWARE,null);
怎么样简单吧，如果有点帮助，帮忙点个赞O(∩_∩)O谢谢！
