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
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));

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);
