如何从内置web浏览器而不是应用程序中的代码打开URL？
我试过了：
try {
Intent myIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(download_link));
startActivity(myIntent);
} catch (ActivityNotFoundException e) {
Toast.makeText(this, "No application can handle this request."
+ " Please install a webbrowser", Toast.LENGTH_LONG).show();
e.printStackTrace();
}
但我有个例外：
No activity found to handle Intent{action=android.intent.action.VIEW data =www.google.com

如果您想向用户显示一个带有所有浏览器列表的对话框，以便他可以选择首选项，下面是示例代码：
private static final String HTTPS = "https://";
private static final String HTTP = "http://";
public static void openBrowser(final Context context, String url) {
if (!url.startsWith(HTTP) && !url.startsWith(HTTPS)) {
url = HTTP + url;
}
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
context.startActivity(Intent.createChooser(intent, "Choose browser"));// Choose browser is arbitrary :)
}
其他回答
dataWebView.setWebViewClient(new VbLinksWebClient() {
@Override
public void onPageFinished(WebView webView, String url) {
super.onPageFinished(webView, url);
}
});
public class VbLinksWebClient extends WebViewClient
{
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
view.getContext().startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(url.trim())));
return true;
}
}
Chrome自定义选项卡现在可用：
第一步是将自定义选项卡支持库添加到build.gradle文件中：
dependencies {
...
compile 'com.android.support:customtabs:24.2.0'
}
然后，要打开chrome自定义选项卡：
String url = "https://www.google.pt/";
CustomTabsIntent.Builder builder = new CustomTabsIntent.Builder();
CustomTabsIntent customTabsIntent = builder.build();
customTabsIntent.launchUrl(this, Uri.parse(url));
有关详细信息：https://developer.chrome.com/multidevice/android/customtabs
我认为这是最好的
openBrowser(context, "http://www.google.com")
将以下代码放入全局类
public static void openBrowser(Context context, String url) {
if (!url.startsWith("http://") && !url.startsWith("https://"))
url = "http://" + url;
Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
context.startActivity(browserIntent);
}
简单和最佳实践
方法1：
String intentUrl="www.google.com";
Intent webIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(intentUrl));
if(webIntent.resolveActivity(getPackageManager())!=null){
startActivity(webIntent);
}else{
/*show Error Toast
or
Open play store to download browser*/
}
方法2：
try{
String intentUrl="www.google.com";
Intent webIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(intentUrl));
startActivity(webIntent);
}catch (ActivityNotFoundException e){
/*show Error Toast
or
Open play store to download browser*/
}
MarkB的反应是正确的。在我的例子中，我使用的是Xamarin，与C#和Xamarin一起使用的代码是：
var uri = Android.Net.Uri.Parse ("http://www.xamarin.com");
var intent = new Intent (Intent.ActionView, uri);
StartActivity (intent);
