create a New Activity extends xyz.leohan.androidnfclib.NfcActivity,implement onNfcTouch() method.Then do other things in an Activit as usual

public class MyActivity extends NfcActivity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);    }    @Override    protected void onNfcTouch() {        //this method will called when a NFC tag touched the phone and can be analysed        //we can get NFC tag id here;    }}

write these in your AndroidManifest.xml.
android:launchMode="singleTask" and the intent-filter is necessary

       <activity            android:name=".yourActivityName"            android:configChanges="keyboardHidden|orientation|screenSize"            android:launchMode="singleTask">            <intent-filter>                <action android:name="android.nfc.action.NDEF_DISCOVERED" />                <category android:name="android.intent.category.DEFAULT" />                <data android:mimeType="*/*" />            </intent-filter>        </activity>
