35.1 Removing the Redundant Code

Before implementing data binding within the ViewModelDemo app, the power of data binding will be demonstrated by deleting all of the code within the project that will no longer be needed by the end of this chapter.

Launch Android Studio, open the ViewModelDemo project, edit the MainFragment.java file and modify the code as follows:

package com.ebookfrenzy.viewmodeldemo.ui.main;

 

import android.arch.lifecycle.Observer;

import android.arch.lifecycle.ViewModelProviders;

 

import android.os.Bundle;

 

import android.support.annotation.NonNull;

import android.support.annotation.Nullable;

import android.support.v4.app.Fragment;

 

import android.view.LayoutInflater;

import android.view.View;

import android.view.ViewGroup;

import android.widget.Button;

import android.widget.EditText;

import android.widget.TextView;

 

import com.ebookfrenzy.viewmodeldemo.R;
