我有一个编辑文本,我想在我的 Editttext 中编写电子邮件验证这是一个xml代码
I have one edittext and I would to to write email validation in my Editttext this is a xml code
<EditText
android:id="@+id/mail"
android:layout_width="match_parent"
android:layout_height="48dp"
android:layout_alignLeft="@+id/phone"
android:layout_below="@+id/phone"
android:layout_marginRight="33dp"
android:layout_marginTop="10dp"
android:background="@drawable/edit_background"
android:ems="10"
android:hint="E-Mail"
android:inputType="textEmailAddress"
android:paddingLeft="20dp"
android:textColor="#7e7e7e"
android:textColorHint="#7e7e7e" >
</EditText>
这是一个java代码
emailInput = mail.getText().toString().trim();
emailPattern = "^[_A-Za-z0-9-]+(\.[_A-Za-z0-9-]+)*@[A-Za-z0-9]+(\.[A-Za-z0-9]+)*(\.[A-Za-z]{2,})$";
if (emailInput.matches(emailPattern)) {
Toast.makeText(getActivity(), "valid email address", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(getActivity(), "Invalid email address", Toast.LENGTH_SHORT).show();
mail.setBackgroundResource(R.drawable.edit_red_line);
}
我无法验证.Toast 消息始终是无效的电子邮件地址".我做错了什么?
I can't validation. The toast message is always "Invalid email address". What am I doing wrong?
为什么不用:
public final static boolean isValidEmail(CharSequence target) {
return !TextUtils.isEmpty(target) && android.util.Patterns.EMAIL_ADDRESS.matcher(target).matches();
}
