    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    root = (LinearLayout) findViewById(R.id.ll_linear_layout);
    ll = (LinearLayout) findViewById(R.id.ll);
    mEditText1 = (EditText) findViewById(R.id.et1);
    mEditText2 = (EditText) findViewById(R.id.et2);
    mEditText3 = (EditText) findViewById(R.id.et3);
    mEditText4 = (EditText) findViewById(R.id.et4);

    mEditText3.setOnFocusChangeListener(mLayoutExtract);
    mEditText4.setOnFocusChangeListener(mListener4);


    mScrollView = new ScrollView(this);

View.OnFocusChangeListener mListener1 = new View.OnFocusChangeListener() {
    @Override
    public void onFocusChange(View view, boolean b) {
        if (b) {

        } else {

        }

};
View.OnFocusChangeListener mListener2 = new View.OnFocusChangeListener() {

Try this

<?xml version="1.0" encoding="utf-8"?>
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:id="@+id/ll_linear_layout"
xmlns:android="http://schemas.android.com/apk/res/android">
<EditText
    android:layout_marginTop="200dp"
    android:id="@+id/et1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:hint="first name"/>
<EditText
    android:id="@+id/et2"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:hint="second name"/>
<EditText
    android:id="@+id/et3"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:hint="second name"/>
    <LinearLayout
        android:id="@+id/ll"
        android:orientation="vertical"
        android:layout_width="match_parent"
        android:layout_height="300dp"
        android:visibility="gone">
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textSize="75dp"
            android:textColor="#000000"
            android:text="Hidable text"/>
    </LinearLayout>
<EditText
    android:id="@+id/et4"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
