1：布局使用webview显示
<WebView
android:id="@+id/recy_webview"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
2：代码实现
//图文混合
//要显示的接口数据
String content = data.getContent();
WebSettings settings = recyWebview.getSettings();
settings.setLayoutAlgorithm(WebSettings.LayoutAlgorithm.SINGLE_COLUMN);//把html中的内容放大webview等宽的一列中
settings.setJavaScriptEnabled(true);//支持js
recyWebview.setHorizontalScrollBarEnabled(false);//水平不显示
recyWebview.setVerticalScrollBarEnabled(false);//垂直不显示
String con = "<html><head><style>img{width:100% !important;}</style></head><body style='margin:0;padding:0'>" + content + "</body></html>";
recyWebview.loadDataWithBaseURL("about:blank", con, "text/html", "utf-8", null);
//实现文章中图片点击监听
recyWebview.addJavascriptInterface(new MJavascriptInterface(getActivity()), "imagelistener");
recyWebview.setWebViewClient(new MyWebViewClient());
@Override
protected void onDestroy() {
if (webviewcontent != null) {
//再次打开页面时，若界面没有消亡，会导致进度条不显示并且界面崩溃
webviewcontent.stopLoading();
webviewcontent.onPause();
webviewcontent.clearCache(true);
webviewcontent.clearHistory();
webviewcontent.removeAllViews();
//先结束未结束线程，以免可能会导致空指针异常
webviewcontent.destroy();
webviewcontent = null;
}
super.onDestroy();
}
public class MyWebViewClient extends WebViewClient {
@Override
public void onPageFinished(WebView view, String url) {
view.getSettings().setJavaScriptEnabled(true);
super.onPageFinished(view, url);
addImageClickListener(view);//待网页加载完全后设置图片点击的监听方法
}
@Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
view.getSettings().setJavaScriptEnabled(true);
super.onPageStarted(view, url, favicon);
}

+ " objs[i].οnclick=function() " +
" { "

}
}
