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

当前回答

试试看:

Uri uri = Uri.parse("https://www.google.com");
startActivity(new Intent(Intent.ACTION_VIEW, uri));

或者如果您希望在活动中打开web浏览器,请执行以下操作:

WebView webView = (WebView) findViewById(R.id.webView1);
WebSettings settings = webview.getSettings();
settings.setJavaScriptEnabled(true);
webView.loadUrl(URL);

如果您想在浏览器中使用缩放控制,则可以使用:

settings.setSupportZoom(true);
settings.setBuiltInZoomControls(true);

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));

所以我找了很长时间,因为所有其他答案都是打开该链接的默认应用程序,而不是默认浏览器,这就是我想要的。

我终于做到了:

// gathering the default browser
final Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://"));
final ResolveInfo resolveInfo = context.getPackageManager()
    .resolveActivity(intent, PackageManager.MATCH_DEFAULT_ONLY);
String defaultBrowserPackageName = resolveInfo.activityInfo.packageName;


final Intent intent2 = new Intent(Intent.ACTION_VIEW);
intent2.setData(Uri.parse(url));

if (!defaultBrowserPackageName.equals("android")) {
    // android = no default browser is set 
    // (android < 6 or fresh browser install or simply no default set)
    // if it's the case (not in this block), it will just use normal way.
    intent2.setPackage(defaultBrowserPackageName);
}

context.startActivity(intent2);

顺便说一句,你可以注意到context.whatever,因为我已经将它用于静态util方法,如果你在一个活动中这样做,它是不需要的。

如果您想以非编程方式对XML执行此操作,可以在TextView上使用:

android:autoLink="web"
android:linksClickable="true"

来自Anko库方法

fun Context.browse(url: String, newTask: Boolean = false): Boolean {
    try {
        val intent = Intent(Intent.ACTION_VIEW)
        intent.data = Uri.parse(url)
        if (newTask) {
            intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
        }
        startActivity(intent)
        return true
    } catch (e: ActivityNotFoundException) {
        e.printStackTrace()
        return false
    }
}
