這是我與Android，我能夠做支付和重定向到成功URL成功後付款，而我要完成活動PayuPayment之旅一體化並返回上一個活動與保存共享值與1請幫助我，每次它重定向到成功URl。如何完成actvity一次響應重定向到成功URL中Payu paymentgetway與Android

你面臨的問題？因爲我可以看到，當成功URL獲得時，你已經完成了你的完成代碼。 –

其重定向到Sucess URL和打印Sucess不完 –

因爲你還沒有覆蓋onPageStarted方法，你可以試試這個方法，

@Override 
public void onPageStarted(WebView view, String url, Bitmap favicon) { 
super.onPageStarted(view, url, favicon); 
if (url.equals(SUCCESS_URL)) { 
Toast.makeText(PayUActvity.this, "Success! ", 
Toast.LENGTH_SHORT).show(); 
SharedPreferences prefs = getSharedPreferences(
AppConstants.PAYMENT_SUCESS, Context.MODE_PRIVATE); 
SharedPreferences.Editor editor = prefs.edit(); 
editor.putString(AppConstants.PAYMENT_SUCESS, "1"); 
editor.commit(); 
finish(); 
} else { 
Toast.makeText(PayUActvity.this, "Something Wrong! ", 
Toast.LENGTH_SHORT).show(); 
} 
}

OK等待讓我試試 –

感謝名單的工作對我來說 –

u能請建議我怎麼去trnscation Id或付款ID在Payu？ –

在您的WebViewClient中替代onPageStarted函數，並將成功url與onPageStarted中包含的url進行比較。如果兩個URL都相同，則啓動任何您想要的活動並關閉此活動。

更新：嘗試類似下面的代碼：

@Override 
     public void onPageStarted(WebView view, String url, Bitmap favicon) { 
      super.onPageStarted(view, url, favicon); 
      if (url.equals(SUCCESS_URL) { 
       // finish activity here 
      } else { 
       // handle other urls here. 
      } 
     }
