Almost all applications have login fucntionality and when we try to create new project we either copy paste the code from other project and add validation for username/password. I have created this library which will validate the fields using 2-3 lines of code. You just need to pass the EditText instance of username and password to LoginBuilder class.
Step to add this import library in your project.
Add this in your root build.gradle at the end of repositories:
step 1
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}
Step 2
dependencies {
implementation 'com.github.vinayakmestri:validotor:0.1.1'
}
Now lets go coding
Your login.xml file would be like
<EditText
android:id="@+id/username"
android:layout_width="match_parent"
android:layout_height="50dp" />
<EditText
android:id="@+id/password"
android:layout_width="match_parent"
android:layout_height="50dp"
android:inputType="textPassword" />
<Button
android:id="@+id/loginButton"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:onClick="onClick"
android:text="Login" />
Add below code in your LoginActivity.java in Onlclick event on Login button
@OnClick({R.id.loginButton})
void onClick(View view) {
// parameters username and password are the EditText intsance.
LoginBuilder loginBuilder = LoginBuilder.getInstance().setPasswordField(password).setUsernameField(username)
.addPasswordValidations(new ValidationBuilder().add(new TextLengthValidator(5,"Short length")).add(new EmptyValidator("Empty password")))
.addUserNameValidations(new ValidationBuilder().add(new EmailValidator("Wrong email")).add(new EmptyValidator("Empty username"))).build();
loginAuthBuilder.setCallBack(new ValidationCallBack() {
@Override
public void onSuccess(String username, String password) {
Toast.makeText(A.this,username+ " "+password,Toast.LENGTH_SHORT).show();
}
@Override
public void onError(int id, String errorCode) {
Toast.makeText(A.this,""+errorCode,Toast.LENGTH_SHORT).show();
}
}).login();
}
