我有一個webview需要打開一個特定的鏈接。當我點擊該鏈接時，它會將我重定向到另一個鏈接......我的問題是我可以打開第一個鏈接，但第二個鏈接不會被調用...請幫助我！Android WebView不加載自動重定向url
這裏是我的代碼：
public class OnlinePayment extends AppCompatActivity {
WebView online_payment_activity_web_view;
String url;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.online_payment_activity);
Bundle extras = getIntent().getExtras();
url = extras.getString("redirect_url");
final ProgressDialog pd = ProgressDialog.show(OnlinePayment.this, "", "Redirecting...", true);
Log.e("Here redirect first", url);
online_payment_activity_web_view=(WebView) findViewById(R.id.online_payment_web_view);
online_payment_activity_web_view.getSettings().setJavaScriptEnabled(true);
online_payment_activity_web_view.getSettings().setSupportZoom(true);
online_payment_activity_web_view.getSettings().setBuiltInZoomControls(true);
online_payment_activity_web_view.getSettings().setDisplayZoomControls(false);
online_payment_activity_web_view.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
online_payment_activity_web_view.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
online_payment_activity_web_view.setWebChromeClient(new WebChromeClient());
online_payment_activity_web_view.getSettings().setLoadWithOverviewMode(true);
online_payment_activity_web_view.getSettings().setUseWideViewPort(true);
online_payment_activity_web_view.setWebViewClient(new WebViewClient() {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
return false;
}
/**
* Notify the host application that an SSL error occurred while loading a
* resource. The host application must call either handler.cancel() or
* handler.proceed(). Note that the decision may be retained for use in
* response to future SSL errors. The default behavior is to cancel the
* load.
*
* @param view The WebView that is initiating the callback.
