Disable Android home button

Question

I'm implementing lock screen apps, user required to key in passcode and unlock the device for some duration.

I test in Samsung Note 3 and xiaomi redmi 1.

All the physical buttons in Note 3 has been locked, but somehow I cannot disable xiaomi redmi 1's home button. **The home button will run onPause event.

I used the code couldn't show the button in logcat.

@Override
    public boolean dispatchKeyEvent(KeyEvent event) {
        Log.d("button", String.valueOf(event.getKeyCode()));
        return true;
    }

I've try to use onPause and run my apps again, but it respond slow.

@Override
public void onPause() {
    super.onPause();.
    Intent intent = new Intent(LockScreenActivity.this, SettingActivity.class);
    startActivity(intent);
}

Try this overridden method

@Override
public void onAttachedToWindow() {
    this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD);
    super.onAttachedToWindow();
}


but it's not a good practice to disable home button.
