Is there a better way to refresh WebView?
提问by cdg
Ok. I have looked EVERYWHERE and my little brain just can't understand a better way to refresh an activity. Any suggestions that I can understand would be great. :)
好的。我已经四处看了看，我的小脑袋无法理解刷新活动的更好方法。任何我能理解的建议都会很棒。:)
Here is the java code:
这是Java代码：
package com.dge.dges;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.webkit.WebView;
import android.widget.Button;
public class dgeActivity extends Activity {
WebView mWebView;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mWebView = (WebView) findViewById(R.id.webview);
mWebView.getSettings();
mWebView.loadUrl("http://www.websitehere.php");
Button newButton = (Button)findViewById(R.id.new_button);
newButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent intent = new Intent(dgeActivity.this, dgeActivity.class);
startActivity(intent);
}
});
}
}
And here is the main.xml
这是 main.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/RelativeLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#000000"
>
<WebView
android:id="@+id/webview"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:scrollbars="none"
/>
<Button
android:id="@+id/new_button"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:text="Refresh"
/>
</RelativeLayout>
I don't like the idea of just re-stacking activity after activity. There has to be an easier way to refresh the webview. Please help. :)
我不喜欢在活动后重新堆叠活动的想法。必须有一种更简单的方法来刷新 webview。请帮忙。:)

You could call an mWebView.reload();That's what it does
你可以打电话给mWebView.reload();这就是它的作用

1) In case you want to reload the same URL:
1) 如果您想重新加载相同的 URL：
mWebView.loadUrl("http://www.websitehere.php");
so the full code would be
所以完整的代码将是
newButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
dgeActivity.this.mWebView.loadUrl("http://www.websitehere.php");
}});
2) You can also call mWebView.reload()but be aware this reposts a page if the request was POST, so only works correctly with GET.
2）您也可以调用，mWebView.reload()但请注意，如果请求是 POST，则会重新发布页面，因此只能与 GET 一起正常工作。

The best solution is to just do webView.loadUrl( "javascript:window.location.reload( true )" );. This should work on all versions and doesn't introduce new history entries.
最好的解决办法就是做webView.loadUrl( "javascript:window.location.reload( true )" );。这应该适用于所有版本，并且不会引入新的历史条目。

This worked for me.
这对我有用。
just put under onCreate metode
只需放在 onCreate 方法下
Button button = (Button) findViewById(R.id.reload_btn);
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
web.loadUrl( "javascript:window.location.reload( true )" );
}
});
This is the code that can reload a website in a webView
这是可以在 webView 中重新加载网站的代码
web.loadUrl( "javascript:window.location.reload( true )" );

Refreshing current webview's URL is not a common usage.
I used this in such a scenario: When user goes to another activity and user come back to webview's activity I reload current URL like this:
刷新当前 webview 的 URL 不是一个常见的用法。
我在这样的场景中使用了它：当用户转到另一个活动并且用户回到 webview 的活动时，我重新加载当前的 URL，如下所示：
public class MyWebviewActivity extends Activity {
WebView mWebView;
....
....
....
@Override
public void onRestart() {
String url = mWebView.getUrl();
String postData = MyUtility.getOptionsDataForPOSTURL(mContext);
mWebView.postUrl(url, EncodingUtils.getBytes(postData, "BASE64"));
}
}
You can also use WebView's reload()function. But note that if you loaded the webview with postUrl(), then mWebView.reload();doesn't work. This also works
您也可以使用 WebView 的reload()功能。但请注意，如果您使用 加载了 webview postUrl()，则mWebView.reload();不起作用。这也有效
String webUrl = webView.getUrl();
mWebView.loadUrl(webUrl);

Why not to try this?
为什么不试试这个？
Swift code to call inside class:
在类内部调用的 Swift 代码：
self.mainFrame.reload()
or external call
或外线电话
myWebV.mainFrame.reload()

Yes for some reason WebView.reload() causes a crash if it failed to load before (something to do with the way it handles history). This is the code I use to refresh my webview. I store the current url in self.url
是的，如果之前无法加载 WebView.reload() 会导致崩溃（与它处理历史的方式有关）。这是我用来刷新我的 webview 的代码。我将当前网址存储在self.url
# 1: Pause timeout and page loading
self.timeout.pause()
sleep(1)
# 2: Check for internet connection (Really lazy way)
while self.page().networkAccessManager().networkAccessible() == QNetworkAccessManager.NotAccessible: sleep(2)
# 3:Try again
if self.url == self.page().mainFrame().url():
self.page().action(QWebPage.Reload)
self.timeout.resume(60)
else:
self.page().action(QWebPage.Stop)
self.page().mainFrame().load(self.url)
self.timeout.resume(30)
return False
