I am learning about Data binding, I tried 3 times now, and I did exactly as the tutorial but I keep getting the error "error: cannot find symbol class ActivityMainBindingImpl" when I run the app,
It generates a java file with the ActivityMainBindingImpl, should be any problem in my SDK?
Main :
private ActivityMainBinding activityMainBinding;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
activityMainBinding = DataBindingUtil.setContentView(this,R.layout.activity_main);
activityMainBinding.setPerson(getCurrentPerson());
}
public Person getCurrentPerson(){
Person person = new Person();
person.setName("lance");
person.setLastName("claudio");
return person;
}
Model :
public class Person {
private String name;
public Person(String name, String lastName) {
this.name = name;
this.lastName = lastName;
}
public Person() {
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
private String lastName;
}

No matter if I clean and rebuild or Invalidate Caches, I can't compile.
You are using an import instead of a variable:
This:
<import alias="user" type="com.dubhe.room.entity.User" />
should be this:
<variable name="user" type="com.dubhe.room.entity.User" />
So, I'm trying to create an onclick listener on a button using databinding using this tutorial.
databinding tutorial so as far as when I keep the onclick inside my activity_main.xml layout the button click works. But I want to send my data to an include_main_layout.xml but it tells me I have the error..

my error is the following lines..
error: cannot find symbol class ActivityMainBindingImpl
I tried cleaning the project and rebuilding from the ground base but still no luck. What is it that I'm doing wrong?
Problem is here.
android:onClick="#{(v)->handlers.onFabClicked()}"
it should be android:onClick="#{handlers.onFabClicked()}" simple.
If you want to pass view parameter from xml then your onClick methos should be like below.
android:onClick="#{(v)->handlers.onFabClicked(v)}"
This is the First time i am using Data Binding ,and from Couple of Hours i am having above error. There is Sufficient question related to same Question but Not able to Solve this issue.

I am not able to solve this issue.How can this issue be solved??
There are lots of things incorrect in your implementation.
Your model class should extend BaseObservable.
Your getters should be #Bindable
Your setters should call notifyPropertyChanged(..)
In your xml, you are saying that "user" is a example.com.test.MainActivity, while I think it is a User?
User mainActivityPresenter = new User(sMan,sMan); is also very weird. Call a User "user" and a Presenter "xxxPresenter". Don't call a User "presenter" if you want to write clear code.
... these are some things I see at a glance, there's probably more. Please read the documentation completely first, it will make your implementation a lot easier:
https://developer.android.com/topic/libraries/data-binding/index.html
Its the Simple and Silly Error i have Done this Time.
Solved with Changing the MainActivity to User
<data>
<variable
name="user"
type="example.com.test.User" />
<import type="android.view.View" />
</data>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
android:id="#+id/firstName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#{user.firstName}" />
<TextView
android:id="#+id/lastName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#{user.lastName}" />
</LinearLayout>
I read more links about this problem, but i dont know whats exactly problem of my project. i set dataBinding as true on build.gradle, below code is my application build.gradle file content

I recently started developing on an android application which uses databinding. My problem now is that I can't run the app because of this error:
Error:(10) Error parsing XML: duplicate attribute
The error occurs in every file using databinding (I am using fragments). I googled for like 3 hours now and I can't find the solution.

inflater, R.layout.fragment_tests, container, false);
View view = binding.getRoot();
binding.setDeadline(stViewModel);
return view;
}
}
And the xml file where the error occurs (debug\layout\fragment_tests.xml). layout_width and layout_height are marked as error:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent" android:tag="layout/fragment_tests_0" xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context="layout.tests">

android:layout_height="match_parent"
android:id="#+id/list_tests"
android:tag="binding_1" />
</LinearLayout>
I really hope someone can help me out.
EDIT: Here the STViewModel class:
public class STViewModel extends BaseObservable {
private ObservableArrayList<Deadline> m_deadline = new ObservableArrayList<>();
#Bindable
public ObservableArrayList<Deadline> getDeadline(){
return m_deadline;
}
public void setDeadline(ObservableArrayList<Deadline> value){
m_deadline = value;
notifyPropertyChanged(BR.deadline);
}
}
I've just found out what the solution is. I just had to delete layout_width and layout_height from the <layout> definition.
<layout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
tools:context="layout.tests">
instead of
<layout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="layout.tests">
Make sure that xmlns:android isn't automatically added to both <layout> and your actual layout ViewGroup:
<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android">
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
...>
</android.support.v4.widget.DrawerLayout>
</layout>
Remove xmlns:android from either place.
Remove the lines
android:layout_width="match_parent"
android:layout_height="match_parent"
under your layout tag in xml. It will result in build error.
i was using "xmlns" attrinute two time that is why was receiving error.
<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/offwhite">
Fixed with below code
<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<android.support.constraint.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/offwhite">
Its got solved by removing all attributes from <layout> fields, i.e by keeping it like
<layout>
<data>
<variable
name=""
type="" />
</data>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
</LinearLayout>
</layout>
You should define
android:orientation
property to LinearLayout.
Your LinearLayout should be like this,
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:tag="layout/fragment_tests_0"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="layout.tests">
<ListView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/list_tests"
android:tag="binding_1" />
</LinearLayout>
