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
实现这一点的常见方法是使用以下代码：
String url = "http://www.stackoverflow.com";
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(url));
startActivity(i);
可以更改为短代码版本。。。
Intent intent = new Intent(Intent.ACTION_VIEW).setData(Uri.parse("http://www.stackoverflow.com"));
startActivity(intent);
or :
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.stackoverflow.com"));
startActivity(intent);
最短！：
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.stackoverflow.com")));
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*/
}
//OnClick侦听器
@Override
public void onClick(View v) {
String webUrl = news.getNewsURL();
if(webUrl!="")
Utils.intentWebURL(mContext, webUrl);
}
//你的Util方法
public static void intentWebURL(Context context, String url) {
if (!url.startsWith("http://") && !url.startsWith("https://")) {
url = "http://" + url;
}
boolean flag = isURL(url);
if (flag) {
Intent browserIntent = new Intent(Intent.ACTION_VIEW,
Uri.parse(url));
context.startActivity(browserIntent);
}
}
在Android 11中打开URL链接的新的更好方法。
try {
val intent = Intent(ACTION_VIEW, Uri.parse(url)).apply {
// The URL should either launch directly in a non-browser app
// (if it’s the default), or in the disambiguation dialog
addCategory(CATEGORY_BROWSABLE)
flags = FLAG_ACTIVITY_NEW_TASK or FLAG_ACTIVITY_REQUIRE_NON_BROWSER or
FLAG_ACTIVITY_REQUIRE_DEFAULT
}
startActivity(intent)
} catch (e: ActivityNotFoundException) {
// Only browser apps are available, or a browser is the default app for this intent
// This code executes in one of the following cases:
// 1. Only browser apps can handle the intent.
// 2. The user has set a browser app as the default app.
// 3. The user hasn't set any app as the default for handling this URL.
openInCustomTabs(url)
}

我检查了每一个答案，但哪个应用程序具有用户想要使用的相同URL的深度链接？
今天我得到了这个案例，答案是browserContent.setPackage（“browser_package_name”）；
例如：
Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.google.com"));
browserIntent.setPackage("com.android.chrome"); // Whatever browser you are using
startActivity(browserIntent);
