我正在嘗試爲我公司的Web應用程序製作應用程序,並且它運行良好。唯一的問題是我有一些來自不同領域的鏈接,比如Youtube,它會打開一些視頻。與指定爲我的域的域相關的所有其他鏈接都將在Web視圖中打開,並在我的應用中顯示該網站。但Youtube鏈接和其他外部網站鏈接不起作用。Webview並未打開Chrome中不同域名的鏈接Android
如果我回想起來,它應該詢問用戶是否要使用基於鏈接的Chrome或Youtube或Facebook應用程序打開它,但它不起作用。
這裏是我的WebView代碼:
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final WebView myWebView = (WebView) findViewById(R.id.webview);
myWebView.loadUrl("http://www.example.com/");
WebSettings webSettings = myWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
myWebView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
myWebView.getSettings().setSupportMultipleWindows(true);
myWebView.setHorizontalScrollBarEnabled(true);
myWebView.getSettings().setDomStorageEnabled(true); // This will allow access
myWebView.setWebViewClient(new WebViewClient() {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (Uri.parse(url).getHost().startsWith("google.com")) {
view.loadUrl(url);
} else {
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
startActivity(intent);
}
return true;
}
});
myWebView.setDownloadListener(new DownloadListener() {
public void onDownloadStart(String url, String userAgent,
String contentDisposition, String mimetype,
long contentLength) {
DownloadManager.Request request = new DownloadManager.Request(
Uri.parse(url));
final String filename = URLUtil.guessFileName(url, contentDisposition, mimetype);
request.allowScanningByMediaScanner();
request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED); //Notify client once download is completed!
request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, filename);
DownloadManager dm = (DownloadManager) getSystemService(DOWNLOAD_SERVICE);
dm.enqueue(request);
Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT); //This is important!
intent.addCategory(Intent.CATEGORY_OPENABLE); //CATEGORY.OPENABLE
intent.setType("*/*");//any application,any extension
Toast.makeText(getApplicationContext(), "Downloading File", //To notify the Client that the file is being downloaded
Toast.LENGTH_LONG).show();
}
});
}
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
// Check if the key event was the Back button and if there's history
WebView myWebView = (WebView) findViewById(R.id.webview);
if ((keyCode == KeyEvent.KEYCODE_BACK) && myWebView.canGoBack()) {
myWebView.goBack();
return true;
}
// If it wasn't the Back key or there's no web page history, bubble up to the default
// system behavior (probably exit the activity)
return super.onKeyDown(keyCode, event);
}
}
我已經試過一切,但它確實從Web瀏覽器不同的域不開的聯繫。哪裏不對?
它說無法解析符號活動。我不知道要在這裏打什麼活動。 –
只是讓它this.startActivity(intent) – user5434084
這對我工作,謝謝! – JoeYo
