TextView加载显示
添加依赖
implementation 'com.zzhoujay.richtext:richtext:3.0.8'implementation 'com.zzhoujay:html:1.0.2'
调用
/*** 加载Html** @param html*/protected void loadHtml(String html, TextView textContent) {try {RichText.fromHtml(html).into(textContent);} catch (Exception e) {e.printStackTrace();}}
WebView加载显示
1、封装webview
public class LollipopFixedWebView extends WebView {public LollipopFixedWebView(Context context) {super(getFixedContext(context));}public LollipopFixedWebView(Context context, AttributeSet attrs) {super(getFixedContext(context), attrs);}public LollipopFixedWebView(Context context, AttributeSet attrs, int defStyleAttr) {super(getFixedContext(context), attrs, defStyleAttr);}@TargetApi(Build.VERSION_CODES.LOLLIPOP)public LollipopFixedWebView(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {super(getFixedContext(context), attrs, defStyleAttr, defStyleRes);}public LollipopFixedWebView(Context context, AttributeSet attrs, int defStyleAttr, boolean privateBrowsing) {super(getFixedContext(context), attrs, defStyleAttr, privateBrowsing);}public static Context getFixedContext(Context context) {if (Build.VERSION.SDK_INT >= 21 && Build.VERSION.SDK_INT < 23) // Android Lollipop 5.0 & 5.1return context.createConfigurationContext(new Configuration());return context;}}
2、引用
<cn.dlc.bangbang.electricbicycle.util.views.LollipopFixedWebViewandroid:id="@+id/webView"android:layout_width="match_parent"android:layout_height="wrap_content"></cn.dlc.bangbang.electricbicycle.util.views.LollipopFixedWebView>
3、java代码实现
方法一
String topss="<html><head><meta charset=\"\"UTF-8\"\"><meta name=\"\"viewport\"\" content=\"\"width=device-width, initial-scale=1.0,user-scalable=no\"\"><meta http-equiv=\"\"X-UA-Compatible\"\" content=\"\"ie=edge\"\"></head><body><style>img{width:100%%!important;height:auto!important;}p{font-size:14px;}</style>";LgqLogutil.e("lll000ll=== "+content);String endss="</body></html>";
方法二
String js = "<script type=\"text/javascript\">"+"var imgs = document.getElementsByTagName('img');" + // 找到img标签"for(var i = 0; i<imgs.length; i++){" + // 逐个改变"imgs[i].style.width = '100%';" + // 宽度改为100%"imgs[i].style.height = 'auto';" +"}" +"</script>";
webView.loadData((data.getProjectDescription()+js).replace("&zoom=640w",""), "text/html;charset=utf-8", null);
webView.loadData((ss+js).replace("&zoom=640w",""), "text/html;charset=utf-8", null);
public void initfte(String ss){WebSettings settings = webView.getSettings();// 设置WebView支持JavaScriptsettings.setJavaScriptEnabled(true);//支持自动适配settings.setUseWideViewPort(true);settings.setLoadWithOverviewMode(true);settings.setSupportZoom(false); //支持放大缩小settings.setBuiltInZoomControls(false); //显示缩放按钮settings.setBlockNetworkImage(true);// 把图片加载放在最后来加载渲染settings.setAllowFileAccess(true); // 允许访问文件settings.setSaveFormData(true);settings.setGeolocationEnabled(true);settings.setDomStorageEnabled(true);settings.setJavaScriptCanOpenWindowsAutomatically(true);/// 支持通过JS打开新窗口settings.setLayoutAlgorithm(WebSettings.LayoutAlgorithm.NARROW_COLUMNS);settings.setLayoutAlgorithm(WebSettings.LayoutAlgorithm.SINGLE_COLUMN);//设置不让其跳转浏览器webView.setWebViewClient(new WebViewClient() {@Overridepublic boolean shouldOverrideUrlLoading(WebView view, String url) {return false;}});// 添加客户端支持webView.setWebChromeClient(new WebChromeClient());// mWebView.loadUrl(TEXTURL);//不加这个图片显示不出来if (Build.VERSION.SDK_INT > Build.VERSION_CODES.LOLLIPOP) {webView.getSettings().setMixedContentMode(WebSettings.MIXED_CONTENT_ALWAYS_ALLOW);}webView.getSettings().setBlockNetworkImage(false);//允许cookie 不然有的网站无法登陆CookieManager mCookieManager = CookieManager.getInstance();mCookieManager.setAcceptCookie(true);mCookieManager.setAcceptThirdPartyCookies(webView, true);webView.loadDataWithBaseURL(null,ss, "text/html" , "utf-8", null);//加载html数据// webView.loadUrl(URL);}
