Iam試圖進行登錄活動 我遇到了問題。我的二傳手不工作，我不知道爲什麼？ 我有3班。安裝員不工作
1日一個是數據與服務器數據和getter和setter
public class Data{
String addressesURL = "/DataSnap/rest/TServerMethods1/LookupCustomers";
String articlesURL = "/DataSnap/rest/TServerMethods1/LookupArticle";
String invoicesURL = "/DataSnap/rest/TServerMethods1/LookupInvoice";
String invoicesDetailsURL = "/DataSnap/rest/TServerMethods1/LookupInvoicePos";
String invoicesDetailsAddressesURL = "/DataSnap/rest/TServerMethods1/LookupInvoiceAddress";
String ordersURL = "/DataSnap/rest/TServerMethods1/LookupOrders";
String ordersDetailsURL = "/DataSnap/rest/TServerMethods1/LookupOrdersPos";
String ordersDetailsAddressesURL = "/DataSnap/rest/TServerMethods1/LookupOrdersAddress";
public String serverURL;
//String serverURL = "http://10.10.10.75:8081";
String username = "admin";
String password = "admin";
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getAddressesURL() {
return addressesURL;
}
public void setAddressesURL(String addressesURL) {
this.addressesURL = addressesURL;
}
public String getArticlesURL() {
return articlesURL;
}
public void setArticlesURL(String articlesURL) {
this.articlesURL = articlesURL;
}
public String getInvoicesURL() {
return invoicesURL;
}
public void setInvoicesURL(String invoicesURL) {
this.invoicesURL = invoicesURL;
}
public String getInvoicesDetailsURL() {
return invoicesDetailsURL;
}
public void setInvoicesDetailsURL(String invoicesDetailsURL) {
this.invoicesDetailsURL = invoicesDetailsURL;
}
public String getInvoicesDetailsAddressesURL() {
return invoicesDetailsAddressesURL;
}
public void setInvoicesDetailsAddressesURL(String invoicesDetailsAddressesURL) {
this.invoicesDetailsAddressesURL = invoicesDetailsAddressesURL;
}
public String getOrdersURL() {
return ordersURL;
}
public void setOrdersURL(String ordersURL) {
this.ordersURL = ordersURL;
}
public String getOrdersDetailsURL() {
return ordersDetailsURL;
}
public void setOrdersDetailsURL(String ordersDetailsURL) {
this.ordersDetailsURL = ordersDetailsURL;
}
public String getOrdersDetailsAddressesURL() {
return ordersDetailsAddressesURL;
}
public void setOrdersDetailsAddressesURL(String ordersDetailsAddressesURL) {
this.ordersDetailsAddressesURL = ordersDetailsAddressesURL;
}
public String getServerURL() {
return serverURL;
}
public void setServerURL(String serverURL) {
this.serverURL = serverURL;
}}
：第二個是我開始我的登錄活動
public class Settings extends AppCompatActivity {
//declarations
//Edittext fields for username , server, password & port information
EditText edtIpurl, edtPort, edtUsername, edtPassword;
//Textviews that can be clicked
TextView databaseDel, databaseRef, magnumgmbh, contact, support;
//imagebuttons for bottom menu
ImageButton contacts, articles, invoices, orders;
//string for server URL
//String sURL = "http://";
Thread newSettingsThread;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_settings);
setTitle("Settings");
newSettingsThread = new Thread(){
public void run(){
runOnUiThread(new Runnable() {
@Override
public void run() {
String serverURL = "http://rest.magnumgmbh.de";
//edtIpurl = (EditText)findViewById(R.id.edtIpurl);
Data newD = new Data();
newD.setServerURL(serverURL);
}
});
}
};
newSettingsThread.start();
//start activitys if bottom buttons clicked
contacts = (ImageButton) findViewById(R.id.contacts);
//articles activity start
contacts.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//start activity addresses
Intent startAddresses = new Intent(Settings.this, Addresses.class);
startActivity(startAddresses);
}
});
}}
和下一個就是我試圖讓我的新serverURL
public class Address extends AppCompatActivity{
Thread newAddressThread;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_addresses);
//set activity name
setTitle("Addresses");
//new thread for network operations
newAddressesThread = new Thread() {
public void run() {
//make text from json
jsonText = new StringBuilder();
try {
String str;
Data newData = new Data();
//json dates url
String addressesURL = newData.getAddressesURL();
String serverUrl = newData.getServerURL();
String username = newData.getUsername();
String password = newData.getPassword();
URL url = new URL(serverUrl + addressesURL);
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
//String encoded = Base64.encode("admin:admin");
String encoded = Base64.encodeToString((username+":"+password).getBytes("UTF-8"), Base64.NO_WRAP);
urlConnection.setRequestProperty("Authorization", "Basic " + encoded);
//check http status code
try {
int statusCode = urlConnection.getResponseCode();
System.out.println(statusCode);
} catch (IOException e) {
}
BufferedReader in = new BufferedReader(new InputStreamReader(urlConnection.getInputStream()));
while ((str = in.readLine()) != null) {
jsonText.append(str);
}
//cast stringbuilder to string
addressesJsonStr = jsonText.toString();
//close IOstream
in.close();
} catch (MalformedURLException e1) {
System.out.println(e1.getMessage());
} catch (IOException e) {
System.out.println(e.getMessage());
}
}
};
//start thread
newAddressesThread.start();
}}
Hier在serverURL中的第三個我得到空，它讓我豁免「Protocol not found: null/DataSnap/rest/TServerMethods1/LookupCustomers「這是我的問題。 我錯了什麼？
兩個不同的對象。您將該值設置爲一個，然後嘗試從另一箇中讀取。這就像你在一個貼子上註明了一個地址，然後你離開那個貼子，它回到原地並回家。在家裏，你再拿一個貼子，並期待地址在那裏寫上... – Fildor
