activity_mai.xml code

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context="xyz.rvconstructions.www.edittextapp.MainActivity">
<EditText android:id="@+id/simpleEditText" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_centerHorizontal="true" android:background="#F2F2F2" android:hint="Enter Your Name Here" android:padding="15dp" android:textColorHint="#000" android:textStyle="bold|italic" android:layout_marginTop="100dp" />

import android.widget.Toast;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final EditText simpleEditText = (EditText) findViewById(R.id.simpleEditText);
Button displayText = (Button) findViewById(R.id.displayText);
displayText.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
if (simpleEditText.getText().toString() != null) {
Toast.makeText(getApplicationContext(), simpleEditText.getText().toString(), Toast.LENGTH_LONG).show(); //display the text that you entered in edit text
