我想要添加6个标签和6个网页浏览
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (url.startsWith("tel:")) {
Intent intent = new Intent(Intent.ACTION_DIAL,
Uri.parse(url));
startActivity(intent);
}else if(url.startsWith("http:") || url.startsWith("https:")) {
view.loadUrl(url);
}
return true;
}
仅针对我的MainActivity.java中的标签6来处理tel：链接如何使其与我的代码一起使用？

我的tab6也用这个
从资产加载一个html文件 if (tab6 != null) {
tab6.setWebViewClient(new WebViewClient());
tab6.loadUrl("file:///android_asset/tab5.html");
}
答案 0 :(得分：0)
我认为你只需要这样做：
if (tab6 != null) {
tab6.setWebViewClient(new WebViewClient() {
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (url.startsWith("tel:")) {
Intent intent = new Intent(Intent.ACTION_DIAL,
Uri.parse(url));
startActivity(intent);
return false;
}
return true;
}
});
tab6.loadUrl("file:///android_asset/tab5.html");
}
请注意不再调用view.loadUrl（'...'）; ＆lt; - 如果你在shouldOverrideURLLoading中返回true，它会将url加载到WebView中。
