Checking empty textEdit

问题

I'm trying to program a simple register application, the user have to fill some fields, where some of them are obligatory. So, I need to check if the user write the info there. I'm doing this:

    for(RequireFields r : RequireFields.values()){
        if(boolValue()){
            switch (r.getField()) {
                case "name":
                    System.out.println("Name");
                    break;
                case "surname":
                    System.out.println("Surname");
                    break;
                case "pass":
                    System.out.println("Pass");
                    break;
                case "email":
                    System.out.println("Email");
                    break;
                case "street":
                    System.out.println("Street");
                    break;
                case "city":
                    System.out.println("City");
                    break;
                case "zip":
                    System.out.println("Zip");
                    break;
            }
        }
    }

Where boolValue() return the status of TextUtils.isEmpty(Field), but this part I don't know how to do it, RequireFileds for now is an enum:

public enum RequireFields {
    NAME("name",1),
    SURNAME("surname",2),
    EMAIL("email",3),
    PASS("pass",4),
    CITY("city",5),
    STREET("street",6),
    ZIP("zip",7);

    private final String field;
    private final int position;

    RequireFields(String field, int position) {
        this.field = field;
        this.position = position;
    }

    public String getField() {
        return field;
    }

    public int getPosition() {
        return position;
    }

}

I put a number with the name, so I can use an iterate for. Any ideas or a easy way to do this?

PD: This is the code for two fields that I used on other app:

    ssid.setError(null);
    pass.setError(null);

    String SSID = ssid.getText().toString();
    String PASS = pass.getText().toString();

    boolean cancel = false;
    View focusView = null;

    if (TextUtils.isEmpty(PASS) && !openWifi) {
        pass.setError(getString(R.string.error_field_pass));
        focusView = pass;
        cancel = true;
    }

    if (TextUtils.isEmpty(SSID)) {
        ssid.setError(getString(R.string.error_field_ssid));
        focusView = ssid;
        cancel = true;
    }

I do this for checking empty EditText...

if (editTextName.getText().toString().equalsIgnoreCase("")) 
{
      // show message/toast for empty name
} 
else if (editTextSurname.getText().toString().equalsIgnoreCase("")) 
{
     // show message/toast for empty Surname
} 
else if (editTextEmail.getText().toString().equalsIgnoreCase(""))  
{
     // show message/toast for empty Email
}
else 
{
     // If above all conditions are false means all fields are not empty so put your action here 
}

Hope this help..

I am not catch what you want. Below is what I had used

add below code to your requireFields

    private static final SparseArray< RequireFields > _map=new SparseArray< RequireFields >();
static {
    for (RequireFields cmd: RequireFields.values())
    {
        _map.put(cmd.position,cmd);
    }
}
public static RequireFields valueOf(int value) { 
  RequireFields field = _map.get(value);
  if (field==null) {
    Log.d("RequireFields","RequireFields position "+value+" not found");
  }
  return field; 
  }

then you can use switch like

switch(RequireFields.valueOf(value){
    case NAME:
        .......    // your handler
        break;
    case SURNAME:
        ....
}

Hope this help
