Override Home button in Android

Hello guys, there is a good news for all. Now I found the solution to override the home button in Android application.

public class DisableHardButton extends Activity {
 TextView mTextView;
 ToggleButton mToggleButton;
 boolean isLock=false;

 @Override
 public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.main);
  mTextView=(TextView) findViewById(R.id.tvInfo);
  mToggleButton=(ToggleButton) findViewById(R.id.btnLock);

  mToggleButton.setOnCheckedChangeListener(new OnCheckedChangeListener() {

   @Override
   public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
    isLock=isChecked;
    onAttachedToWindow();
   }
  });
 }

 @Override
 public boolean dispatchKeyEvent(KeyEvent event) {

  if ( (event.getKeyCode() == KeyEvent.KEYCODE_HOME) && isLock) {
   mTextView.setText("KEYCODE_HOME");
   return true;
   
  } else {
   return super.dispatchKeyEvent(event);
  }
   
 }
 @Override
 public boolean onKeyDown(int keyCode, KeyEvent event) {

  if( (keyCode==KeyEvent.KEYCODE_BACK) && isLock) {
   mTextView.setText("KEYCODE_BACK");
   return true;
 
  }else {
   return super.onKeyDown(keyCode, event);
  }
 }
 
 @Override
 public void onAttachedToWindow() {  
  System.out.println("Onactivity attached :"+isLock);
  
  if(isLock) {   
   this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD);     
   super.onAttachedToWindow();
  
  }else {
   this.getWindow().setType(WindowManager.LayoutParams.TYPE_APPLICATION);     
   super.onAttachedToWindow();
  }
 }
}

This is layout file main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/tvInfo"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="Hi! This is the testing of override home button" />

    <ToggleButton
        android:id="@+id/btnLock"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textOff="UnLocked"
        android:textOn="Locked" />

</LinearLayout>
