1. HttpUrl类（管理Url地址）
/**
* Created by liy on 2017-01-11.
*/
public class HttpUrl {
public String defaultIP = "192.168.10.111:8080";//出厂IP地址
public String publicIP="";//当前设置的IP地址
private Settings settings;
private Activity activity;
public String publicUrl="";
/****************************************所有的网络地址*******************************************************/
public String loginUrl = "";
public String logoutUrl = "";
private static HttpUrl httpUrl;
public static HttpUrl getHttpUrl(){
if(httpUrl==null){
httpUrl = new HttpUrl();
}
return httpUrl;
}
private HttpUrl(){
settings = Settings.getInstance(activity);
if (settings.getIP()!=""){
publicIP=settings.getIP();
}else{
publicIP = defaultIP;
settings.setIP(publicIP);//解决首次不显示默认IP
}
/*publicUrl="http://"+publicIP+":8080/jkpms";*/
publicUrl="http://"+publicIP+"/jkpms";
setAllUrl(publicUrl);
}
public void refleshIP(){
settings = Settings.getInstance(activity);
if (settings.getIP()!=""){
publicIP=settings.getIP();
}else{
publicIP = defaultIP;
settings.setIP(publicIP);
}
/*publicUrl="http://"+publicIP+":8080/jkpms";*/
publicUrl="http://"+publicIP+"/jkpms";
setAllUrl(publicUrl);
}
private void setAllUrl(String publicUrl){
loginUrl = publicUrl+"//pmsAppMy/UserLogin.do";
logoutUrl = publicUrl+"//pmsAppMy/logOutByUserId.do";
}
}
备注：无参构造函数和刷新IP的函数代码此时一样，可根据需求进行对应的修改
2. Settings类（SharedPreferences管理）
/**
* Created by liy on 2016-12-12.
*/
public class Settings {
private static final String PREFERENCE = "settings";
private SharedPreferences sharedPreferences;
private static final String SETIP="set_IP";//上次设置的IP
/**
* 单例模式
*/
private static Settings preferences;
private Settings(Context context){
sharedPreferences=context.getSharedPreferences(PREFERENCE,Context.MODE_PRIVATE);
}
public static Settings getInstance(Context context){
if(preferences==null){
preferences=new Settings(context);
}
return preferences;
}
/**
* 修改IP和Port
*/
public synchronized void setIP(String urlIP){
SharedPreferences.Editor editor=sharedPreferences.edit();
editor.putString(SETIP,urlIP);
editor.commit();
}
public synchronized String getIP(){
return sharedPreferences.getString(SETIP,"");
}
}
3. SystemSettingActivity
public class SystemSettingActivity extends FragmentActivity {
private static final String TAG=SystemSettingActivity.class.getName();
private Button submit;//IP确定
private EditText IP_content1;//IP第1个字段输入框
private EditText IP_content2;//IP第2个字段输入框
private EditText IP_content3;//IP第3个字段输入框
private EditText IP_content4;//IP第4个字段输入框
private EditText port_number;//端口号
private Settings settings;//设置
private Button IP_settings;//IP还原
