标签：android

本次介绍 AndroidManifest 中注册方式。

1、添加NFC权限

<uses-permission android:name="android.permission.NFC" />

2、在Activity中添加事件

<activity
	android:name=".MainActivity"
	android:configChanges="keyboardHidden|orientation"
	android:launchMode="singleTask"
	android:screenOrientation="portrait">
	<intent-filter>
	    <action android:name="android.intent.action.MAIN" />
	    <category android:name="android.intent.category.DEFAULT" />
	</intent-filter>
	<intent-filter>
            <action android:name="android.nfc.action.TAG_DISCOVERED" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
	<meta-data
	    android:name="android.nfc.action.TECH_DISCOVERED"
	    android:resource="@xml/nfc_tech_filter" />
</activity>

3、创建 nfc_tech_filter.xml 文件内容，xml保存路径在 res/xml/ 下

<?xml version="1.0" encoding="utf-8"?>
<resources xmlns:xliff="urn:oasis:names:tc:xliff:document:1.2" >
    <tech-list>
        <tech>android.nfc.tech.MifareClassic</tech>
    </tech-list>
    <tech-list>
        <tech>android.nfc.tech.MifareUltralight</tech>
    </tech-list>
    <tech-list>
        <tech>android.nfc.tech.NfcA</tech>
    </tech-list>
    <tech-list>
        <tech>android.nfc.tech.NfcF</tech>
    </tech-list>
    <tech-list>
        <tech>android.nfc.tech.Ndef</tech>
    </tech-list>
    <tech-list>
        <tech>android.nfc.tech.NfcV</tech>
    </tech-list>
    <tech-list>
        <tech>android.nfc.tech.NfcB</tech>
    </tech-list>
    <tech-list>
        <tech>android.nfc.tech.NdefFormatable</tech>
    </tech-list>
    <tech-list>
        <tech>android.nfc.tech.IsoDep</tech>
    </tech-list>
</resources>
