Java 当url包含http时，在设置WebViewCore之前不支持Android:removeMessages（int what=107）

我写了一个简单的程序，可以直接将网页加载到web视图中

URL包含http://并且web视图工作得很好，除了这个恼人的107错误之外，大多数ppl认为这是因为您的URL不包含http头

我在网上到处搜索，找不到和我的案子类似的东西

我的XML看起来像：

import android.app.Activity;
import android.app.ProgressDialog;
import android.content.Context;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.LinearLayout;

public class MobileWebView extends Activity{
private WebView myWebView;
final Context context = this;   //set the context to be itself
ProgressDialog progressDialog;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {

    myWebView.setWebViewClient(new MyWebViewClient(){

        }

    SetupNavBar();

    nb.setNavigationBarListener(nbl);

    ll.addView(nb);

//override the override loading method for the webview client
private class MyWebViewClient extends WebViewClient {

    @Override

        } else {
            return false;
        }
    }

}

在我的主课中，我称之为：

final Context context = this;   //set the context to be itself
private void setup(){
    //assign buttons
    Button login = (Button)findViewById(R.id.loginButton);
    Button register = (Button)findViewById(R.id.registerButton);

    //setup onclick for each button
    bindButtonWithVisitWebsite(login, "https://onlinedoctor.lloydspharmacy.com/login");
    bindButtonWithVisitWebsite(register,"https://onlinedoctor.lloydspharmacy.com/register");
}

private void bindButtonWithVisitWebsite(Button b, final String urlName){
    b.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            Bundle bundle = new Bundle();
            bundle.putString("site",urlName);
            Intent intent = new Intent(context, MobileWebView.class);
            intent.putExtras(bundle);
        }
    });
}

这在ICS中对我起了作用。

我也有同样的问题。你有什么发现吗？没有。仍然期待着如何解决这个问题，尽管这个程序在任何情况下都能工作，只是不知道如何利用例外可能重复的Hi Sam：如果你看我的url，它是一个https://，所以它与这个问题有点不同，因为它不能解决我的问题。我也有同样的问题。你修好它成功了吗？你能帮忙吗？谢谢你的回答，但是在我的情况下它也不能修复这个错误：-s

WebSettings settings = webView.getSettings();
settings.setPluginState(PluginState.ON);
