嗨在我的应用程序中检查电子邮件ID和电话号码的验证，但它没有验证两者，只是将其保存到数据库中。 我想查看电子邮件ID和电话号码，如果它们都正确我想要进行下一个流程 任何人都可以帮助我
ContactUs.java
public class ContactUs extends Activity
{
EditText fname1,lname1,mobile1,altmob1,email1,comment1;
String data="";
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.contactus);
fname1=(EditText) findViewById(R.id.fname);
lname1=(EditText) findViewById(R.id.lname);
mobile1=(EditText) findViewById(R.id.mobile);
altmob1=(EditText) findViewById(R.id.altno);
email1=(EditText) findViewById(R.id.email);
comment1=(EditText) findViewById(R.id.coment);
Button Send = (Button) findViewById(R.id.Send);
Send.setOnClickListener(new OnClickListener() {
public void onClick(View v)
{
String fname = fname1.getText().toString();
String lname = lname1.getText().toString();
String mobile = mobile1.getText().toString();
String altmob = altmob1.getText().toString();
String email = email1.getText().toString();
String comment = comment1.getText().toString();
if(fname.equals(""))
{
fname1.setError( "Please Enter First Name" );
}
else if(lname.equals(""))
{
lname1.setError( "Please Enter Last Name" );
}
else if(mobile.equals(""))
{
mobile1.setError( "Please Enter Mobile No." );
isValidMobile(mobile);
}
else if(altmob.equals(""))
{
altmob1.setError( "Please Enter Altenative Mobile No." );
}
else if(email.equals(""))
{
email1.setError( "Please Enter EmailId" );
isValidMail(email);
}
else if(comment.equals(""))
{
comment1.setError( "Please Enter Your Comments here" );
}
else
{
try{
String queryString ="fname="+ fname

data = DatabaseUtility.executeQueryPhp("Contactform",queryString);
fname1.setText("");

mobile1.setText("");
altmob1.setText("");
email1.setText("");
comment1.setText("");
Toast.makeText(

}
private boolean isValidMail(String email)

return check;
}
private boolean isValidMobile(String mobile)
{
boolean check;
if(mobile.length() < 6 || mobile.length() > 13)
{
check = false;
mobile1.setError("Not Valid Number");
}
else
{

有包含属性电子邮件的edittext框
机器人：的inputType = “textEmailAddress”
代码
else if(mobile.equals(""))
{
mobile1.setError( "Please Enter Mobile No." );
isValidMobile(mobile);
}
检查电子邮件是否为空，然后转到isValidMobile
所以使用
else if(mobile.equals(""))
{
mobile1.setError( "Please Enter Mobile No." );
}
else if(!isValidMobile(mobile)){
// do somting
}
和电子邮件类似

请尝试检查电子邮件：
public final static boolean isValidEmail(CharSequence target) {
if (target == null) {
return false;
} else {
return android.util.Patterns.EMAIL_ADDRESS.matcher(target).matches();
}
}
电话号码检查：
public final static boolean isValidPhone(CharSequence target) {
if (target == null) {
return false;
} else {
return android.util.Patterns.PHONE.matcher(target).matches();
}
}
请使用as：
更新您的代码 public class ContactUs extends Activity {
EditText fname1, lname1, mobile1, altmob1, email1, comment1;
String data = "";
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

email1 = (EditText) findViewById(R.id.email);
comment1 = (EditText) findViewById(R.id.coment);
Button Send = (Button) findViewById(R.id.Send);
Send.setOnClickListener(new OnClickListener() {

String comment = comment1.getText().toString().trim();
if (fname.length() != 0) {
if (lname.length() != 0) {
if (mobile.length() != 0 && isValidMobile(mobile)) {
if (altmob.length() != 0 && isValidMobile(altmob)) {
if (email.length() != 0 && isValidMail(email)) {
if (comment.length() != 0) {
try {
String queryString = "fname="
+ fname + "&lname=" + lname

您正在运行有效的电子邮件检查，但忽略了结果。只要您输入一些文本，保存的调用就会起作用。
如果合并了有效检查方法的返回值，则可以在这些调用返回false时停止保存。
e.g。
if(mobile.equals(""))
{
mobile1.setError( "Please Enter Mobile No." );
}
else if(!isValidMobile(mobile))
{
mobile1.setError("Not Valid Number");
}
