1.Webview有goback
方法,点击后可以保存网页状态。
2.我的布局是一个Linearlayout,它有两个按钮顶部的webview。
每个按钮都匹配一个网址。我还在webView.goBack()
方法
onKeyDown
第一个网址有一个表单,第二个网址没有表单
在点击第二个按钮后,我在第一个网址的表单中写了一些信息 然后,我点击第一个按钮,但是网址重新加载。但是如果我点击后退 表单信息保存。 我想保存那些表单信息,就像我点击后退按钮,它可以保存最后的表单信息
我想在上次保存表单信息,怎么做?
我的代码在这里
private void checkone(String url) {
if (!Netutils.isNetworkAvalible(MyApplication.mcontext)) {
fl.removeAllViews();
webView.loadUrl(url);
webView.setVisibility(View.GONE);
webView.removeAllViews();

fl.addView(mErrorView);
} else {
handler.postDelayed(new Runnable() {
@Override

fl.setVisibility(View.GONE);
webView.setVisibility(View.VISIBLE);
fl.removeAllViews();
}
},1000);
Map extraHeaders = new HashMap();
extraHeaders.put("Referer", "www.emiaoqian.com");
webView.loadUrl(url, extraHeaders);

webView.setWebChromeClient(new ChomeClient(this) {

}
}
@Override

showErrorPage();
}
@Override

fixDirPath();
// webParentView = (LinearLayout) webView.getParent();
}
}
答案 0 :(得分:0)
您可以设置:
[assembly: ExportRenderer(typeof(CustomEntryControl), typeof(MyEntryRenderer))]
namespace MyApp.Droid
{
public class MyEntryRenderer : EntryRenderer
{
protected override void OnElementChanged(ElementChangedEventArgs<Entry> e)
{
base.OnElementChanged(e);
if (Control != null)
{
Control.SetBackgroundColor(global::Android.Graphics.Color.LightGreen);
}
}
}
}
还要保存在指定应用缓存路径:
mWebView.getSettings().setCacheMode(WebSettings.LOAD_DEFAULT); // WebSettings.LOAD_CACHE_ELSE_NETWORK
告诉我结果。
