问题描述

我想给敬酒时的WebView是完全加载。但是,敬酒从不露面,我不知道why..here是我的code:

 公共类WebViewSignUp延伸活动{

    的WebView mWebView;

    @覆盖
    公共无效的onCreate(包savedInstanceState){
        super.onCreate(savedInstanceState);
        的setContentView(R.layout.webviewsignup);

        mWebView =(web视图)findViewById(R.id.webview);
        mWebView.getSettings()setJavaScriptEnabled(真)。

        ((TextView中)findViewById(R.id.home))。setOnClickListener(新OnClickListener(){
            公共无效的onClick(视图v){
                完();
            }
         });

    mWebView.setWebViewClient(新WebViewClient(){
        @覆盖
        公共无效onPageFinished(web视图查看,字符串URL){
             super.onPageFinished(mWebView,URL);

            Toast.makeText(getApplicationContext(),完成!,Toast.LENGTH_SHORT).show();
        }
    });
    mWebView.loadUrl(http://pabebbe.com/m/register);

    mWebView.setWebViewClient(新WebViewClient(){
       公共无效onReceivedError(web视图来看,INT错误code,字符串描述,字符串failingUrl){
         Toast.makeText(getApplicationContext(),哦,不!+描述,Toast.LENGTH_SHORT).show();
       }
       });
    }
}
 

解决方案

要在第二个电话 setWebViewClient()被覆盖的第一个。

创建了 WebViewClient 既覆盖在同一个类只有一个实例,并调用 setWebViewClient 只有一次。然后加载web视图:

  mWebView.setWebViewClient(新WebViewClient(){
    @覆盖
    公共无效onPageFinished(web视图查看,字符串URL){
        super.onPageFinished(mWebView,URL);
        Toast.makeText(getApplicationContext(),完成!,Toast.LENGTH_SHORT).show();
    }

    @覆盖
    公共无效onReceivedError(web视图来看,INT错误code,字符串描述,字符串failingUrl){
        Toast.makeText(getApplicationContext(),哦,不!+描述,Toast.LENGTH_SHORT).show();
    }
});
mWebView.loadUrl(http://pabebbe.com/m/register);
 

I want to show a toast when the webview is totally loaded. But the toast never show up, i don't know why..here is my code:

public class WebViewSignUp extends Activity{

    WebView mWebView;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.webviewsignup);

        mWebView = (WebView) findViewById(R.id.webview);
        mWebView.getSettings().setJavaScriptEnabled(true);

        ((TextView)findViewById(R.id.home)).setOnClickListener(new OnClickListener(){
            public void onClick(View v) {
                finish();
            }
         });

    mWebView.setWebViewClient(new WebViewClient() {
        @Override
        public void onPageFinished(WebView view, String url) {
             super.onPageFinished(mWebView, url);

            Toast.makeText(getApplicationContext(), "Done!", Toast.LENGTH_SHORT).show();
        }
    });
    mWebView.loadUrl("http://pabebbe.com/m/register");

    mWebView.setWebViewClient(new WebViewClient() {
       public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
         Toast.makeText(getApplicationContext(), "Oh no! " + description, Toast.LENGTH_SHORT).show();
       }
       });
    }
}
解决方案

The second call to setWebViewClient() is overwriting the first.

Create only a single instance of WebViewClient with both overrides in the same class, and call setWebViewClient only once. Then load the Webview:

mWebView.setWebViewClient(new WebViewClient() {
    @Override
    public void onPageFinished(WebView view, String url) {
        super.onPageFinished(mWebView, url);
        Toast.makeText(getApplicationContext(), "Done!", Toast.LENGTH_SHORT).show();
    }

    @Override
    public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
        Toast.makeText(getApplicationContext(), "Oh no! " + description, Toast.LENGTH_SHORT).show();
    }
});
mWebView.loadUrl("http://pabebbe.com/m/register");
