Answer 1

1）您应首先检查您使用的变量是否存在

2）同时在public class PayPalWebViewActivity extends AppCompatActivity { WebView webView; String urls,intent_value,paypalId,paymentStatus,cancelPayment,currencyCode,country,cmd,title,language, fn,ln,city,st,zp,add1,add2,bookig_id,pck_id,pck_title,user_id,total,postData; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_pay_pal_web_view); webView = (WebView) findViewById(R.id.webView_paypal); paypalId = "info@guideturbo.com"; paymentStatus = "http://www.guideturbo.com/payments/payment_status"; cancelPayment = "http://www.guideturbo.com/payments/payment_status"; currencyCode = "USD"; country = "USA"; cmd = "_xclick"; title = "Ms"; language = "EN"; try { if (getIntent().getExtras() != null) { bookig_id = getIntent().getStringExtra("booking_id"); pck_id = getIntent().getStringExtra("package_id"); pck_title = getIntent().getStringExtra("title"); total = getIntent().getStringExtra("total"); fn = getIntent().getStringExtra("fn"); ln = getIntent().getStringExtra("ln"); city = getIntent().getStringExtra("city"); st = getIntent().getStringExtra("state"); add1 = getIntent().getStringExtra("add1"); add2 = getIntent().getStringExtra("add2"); zp = getIntent().getStringExtra("zp"); user_id = getIntent().getStringExtra("user_id"); } total = total.replace("$",""); urls = "https://www.paypal.com/cgi-bin/webscr?"+"business="+paypalId +"&"+"return="+paymentStatus +"&"+"cancel_return="+cancelPayment +"&" +"language="+language +"&"+"title="+title +"&"+"first_name="+fn +"&"+"last_name="+ln +"&"+"country="+country +"&" +"cmd="+cmd +"&"+"amount="+total +"&"+"custom="+bookig_id +"&"+"item_name="+pck_title +"&"+"package_id="+pck_id +"&" +"user_id="+user_id +"&"+"currency_code="+currencyCode +"&"+"address1="+add1 +"&"+"address2="+add2 +"&"+"city="+city +"&" +"state="+st +"&"+"zip="+zp; }catch (Exception e){ e.printStackTrace(); } webView.getSettings().setJavaScriptEnabled(true); WebSettings settings = webView.getSettings(); settings.setDomStorageEnabled(true); webView.getSettings().setBuiltInZoomControls(true); webView.getSettings().setDisplayZoomControls(false); webView.setWebViewClient(new MyWebViewClient()); webView.loadUrl(urls); } private class MyWebViewClient extends WebViewClient { @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { /*view.loadUrl(url); return true;*/ if(url.contains(urls)){ //do something view.loadUrl(urls); } return true; } } }

中传递$sqli

mysqli_error();

为什么代码中没有deal_price更新？
