如何使用ViewModel将TextView的输入更新为EditText？

implementation 'androidx.lifecycle:lifecycle-viewmodel:2.4.0'

import androidx.lifecycle.MutableLiveData;
import androidx.lifecycle.ViewModel;

public class TextViewViewModel extends ViewModel {
    private MutableLiveData<String> textLiveData = new MutableLiveData<>();

    public void updateText(String newText) {
        textLiveData.setValue(newText);
    }

    public MutableLiveData<String> getTextLiveData() {
        return textLiveData;
    }
}

TextViewViewModel viewModel = new ViewModelProvider(this).get(TextViewViewModel.class);

<LinearLayout 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">

    <EditText
        android:id="@+id/editText"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="Enter text" />

    <TextView
        android:id="@+id/textView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="@{viewModel.textLiveData}" />

</LinearLayout>

EditText editText = findViewById(R.id.editText);
TextView textView = findViewById(R.id.textView);

editText.addTextChangedListener(new TextWatcher() {
    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {
    }

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

    @Override
    public void afterTextChanged(Editable s) {
    }
});

viewModel.getTextLiveData().observe(this, newText -> {
    textView.setText(newText);
});
