我只想在单击按钮时阅读NFC

Question

我遵循此link来从标签中读取NFC，但我成功了，但是问题是，我只想在单击按钮时才读取NFC。因此，在新的Intent中，我做到了

@Override
protected void onNewIntent(Intent intent) {
    /**
     * This method gets called, when a new Intent gets associated with the current activity instance.
     * Instead of creating a new activity, onNewIntent will be called. For more information have a look
     * at the documentation.
     *
     * In our case this method gets called, when the user attaches a Tag to the device.
     */
    readTag.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            bottomNavigationItemNFC.setVisibility(View.VISIBLE);
            handleIntent(intent);
        }
    });

}

但是在单击按钮之前，它仍在读取NFC标签。

这是我的首次发帖问题，如有任何错误，请原谅。谢谢
