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
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);
}
其他回答
//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);
}
}
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*/
}
试试这个OmegaIntentBuilder
OmegaIntentBuilder.from(context)
.web("Your url here")
.createIntentHandler()
.failToast("You don't have app for open urls")
.startActivity();
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);
Intent getWebPage = new Intent(Intent.ACTION_VIEW, Uri.parse(MyLink));
startActivity(getWebPage);
