    @Override
    public void onClick(View v) {
        Intent intentToFinish = new Intent(WizardThree.this, FinishActivity.class);
        //重点是下面这一句
        intentToFinish.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
        intentToFinish.putExtra("setting", setting);
        startActivity(intentToFinish);
