我有 6 个标签和 6 个 webviews 我想添加这个
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;
}
仅适用于我的 MainActivity.java 中的选项卡 6 来处理电话：链接如何使它与我的代码一起使用？
