我想在webview完全加载时显示吐司。但吐司永远不会出现,我不知道为什么......我的代码是:
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();
}
});
}
}

第二次调用setWebViewClient()
会覆盖第一次。
只创建一个WebViewClient
个实例,并在同一个类中包含两个覆盖,并且只调用setWebViewClient
一次。然后加载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");

@mportuesisf 是 100% 正确的,还要注意在回调中你调用了错误的 webview 的 onPageFinished。如果您使用客户端有多个 webview,这可能是相关的。我会修复:
super.onPageFinished(mWebView, url);
到
super.onPageFinished(view, url);
