Edittext cursor resetting to left after Android Data Binding update

I am trying out the new Android Data Binding library (1.0-rc1) and I have made a User object with three String fields (name, email, and age) and linked them to 3 EditTexts in my layout.

On the first field (name) I placed a TextWatcher. Everything seems to work well. I prevented the notifyPropertyChanged loop in the name field by checking to see if the text is different before allowing it to call setName.

The problem is, every time I type in the name field, the cursor resets to the left of the EditText after each character. I googled around for a solution but most fix suggestions for a cursor issue say to grab a reference to the EditText and adjust the cursor position manually. But I'd like to avoid doing that since I then need to findViewByID to the EditText and the point of Data Binding was to try to avoid doing that. Thank you for your help.

My layout looks like this:

<layout>

<data>
    <variable name="user" type="com.carlpoole.databindingstest.User"/>
</data>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:bind="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
    android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivity">

    <EditText
        android:layout_width="200dp"
        android:layout_height="wrap_content"
        android:id="@+id/name"
        android:text="@{user.name}"
        bind:addTextChangedListener="@{user.nameChanged}"
        />

    <EditText
        android:layout_width="200dp"
        android:layout_height="wrap_content"
        android:id="@+id/email"
        android:layout_below="@+id/name"
        android:text="@{user.email}"/>

    <EditText
        android:layout_width="200dp"
        android:layout_height="wrap_content"
        android:id="@+id/age"
        android:layout_below="@+id/email"
        android:text="@{user.age}"/>

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/age"
        android:text="@{user.name}"/>

</RelativeLayout>

My user object looks like this:

import android.databinding.BaseObservable;
import android.databinding.Bindable;
import android.text.Editable;
import android.text.TextWatcher;

public class User extends BaseObservable {

    private String name;
    private String email;
    private String age;

    public User(String name, String email, String age) {
        this.name = name;
        this.email = email;
        this.age = age;
    }

    public User(){};

    @Bindable
    public String getName() {
        return name;
    }

    @Bindable
    public String getEmail() {
        return email;
    }

    @Bindable
    public String getAge() {
        return age;
    }

    public final TextWatcher nameChanged = new TextWatcher() {
        @Override
        public void afterTextChanged(Editable s) {
            if(!s.toString().equalsIgnoreCase(name))
                setName(s.toString());
        }

        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {}

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {}
    };

    public void setName(String name) {
        this.name = name;
        notifyPropertyChanged(com.carlpoole.databindingstest.BR.name);
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public void setAge(String age) {
        this.age = age;
    }
}

My activity looks like this

import android.databinding.DataBindingUtil;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import com.carlpoole.databindingstest.databinding.ActivityMainBinding;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        ActivityMainBinding binding = DataBindingUtil.setContentView(this, R.layout.activity_main);
        User user = new User("Carl Poole", "mail@carlpoole.com", "26");
        binding.setUser(user);

    }
}

Your best bet here is to use a custom @BindingAdapter which will already have a reference to the EditText. That way you can avoid re-binding if the text in the EditText matches your model, which will resolve your cursor issue.

First, change android:text="@{user.name}" to bind:binding="@{user.name}". Then, add this static method anywhere in your project. We keep all of them in a class called BindingAdapters.java. By the way, starting in RC2 you can create non-static binding adapter methods, but that probably isn't your biggest concern right now.

@BindingAdapter("binding")
public static void bindEditText(EditText editText, CharSequence value) {
  if (!editText.getText().toString().equals(value.toString())) {
    editText.setText(value);
  }
}
