Email validation only if field is non empty
This code works for username and mobile no according to my choice but it does not work for email validation. Note I want to check email only it is nonempty.How to check validation for email only this field is nonempty.**Remember I know the logics But how to put the logics in this code because ** I have tried several logics but in email edit text does nothing.
public class Login extends BaseActivity {
JSONObject jsonobject;
JSONArray jsonarray;
private ProgressDialog dialog;
ArrayList<String> arealist;
//ArrayList<GetterSetter> area;
public static final String PREFS_NAME = "MyPrefsFile";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
Button login = (Button) findViewById(R.id.button_register);
login.setOnClickListener(new View.OnClickListener()
{
@Override
public void onClick(View v) {
EditText user = (EditText) findViewById(R.id.editText_enter_name);
EditText mobile = (EditText) findViewById(R.id.editText_mobNo);
EditText email = (EditText) findViewById(R.id.editText_email);
// Check The Validity of empty fields
boolean Resp = validate(new EditText[]{user,mobile});
// Check The Validity of emailID
boolean e_valid = isEmailValid(email.getText());
// Check The Validity of Mobile Numbers
boolean mobile_valid = isMobValid(mobile.getText());
if (Resp && mobile_valid && e_valid) {
PostJson();
} else {
Toast.makeText(Login.this, "Field incorrect..!!!",
Toast.LENGTH_SHORT).show();
}
if (Resp) {
String pass = mobile.getText().toString();

for validating email id use Android's default Email mathcher.
android.util.Patterns.EMAIL_ADDRESS.matcher(your data).matches();
For Example.
if (etMail.getText().toString().trim().equals("")) {
Toast.makeText(getApplicationContext(),
"Please enter your e-mail id", Toast.LENGTH_SHORT)
.show();
} else if (!android.util.Patterns.EMAIL_ADDRESS.matcher(
etMail.getText().toString().trim()).matches()) {
Toast.makeText(getApplicationContext(),
"Please enter valid e-mail id", Toast.LENGTH_SHORT)
.show();
}else{
// Do your stuff
}
EDIT :
if (user.getText().toString().trim().equals("")) {
Toast.makeText(getApplicationContext(),
"Please enter username", Toast.LENGTH_SHORT)
.show();
} else if (mobile.getText().toString().trim().equals("")) {
Toast.makeText(getApplicationContext(),
"Please enter your mobile number", Toast.LENGTH_SHORT)
.show();
} else if (mobile.getText().length() < 10) {
Toast.makeText(getApplicationContext(),
"Please enter valid mobile number", Toast.LENGTH_SHORT)
.show();
} else if (!etMail.getText().toString().trim().equals("")) {
if (!android.util.Patterns.EMAIL_ADDRESS.matcher(
etMail.getText().toString().trim()).matches()) {
Toast.makeText(getApplicationContext(),
"Please enter valid e-mail id", Toast.LENGTH_SHORT)
.show();
}
}else{
// Do your stuff
}
Happy Coding..

You need to check this :
if (email.getText().toString().equalsIgnoreCase("")) {
// email is empty
} else {
//email is not empty
}
