Android NFC-无法检测标签

未调用onNewIntent（Intent-Intent）方法

我正在尝试的代码是

public class NfcTagDetector extends Activity{

private NfcAdapter mNfcAdapter;
private PendingIntent pendingIntent;
private IntentFilter[] intentFiltersArray;


@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.detect_tag);
    pendingIntent = PendingIntent.getActivity(
            this, 0, new Intent(this, getClass()).addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP), 0);
    mNfcAdapter = NfcAdapter.getDefaultAdapter(this);
    IntentFilter discovery=new IntentFilter(NfcAdapter.ACTION_TAG_DISCOVERED);
    IntentFilter ndefDetected = new IntentFilter(NfcAdapter.ACTION_NDEF_DISCOVERED);        
    IntentFilter techDetected = new IntentFilter(NfcAdapter.ACTION_TECH_DISCOVERED);

    // Intent filters for writing to a tag
    intentFiltersArray = new IntentFilter[] { discovery,ndefDetected,techDetected };
}

public void onPause() {
    super.onPause();
    mNfcAdapter.disableForegroundDispatch(this);
}

public void onResume() {
    super.onResume();
    mNfcAdapter.enableForegroundDispatch(this, pendingIntent, intentFiltersArray, null);
}

@Override
protected void onNewIntent(Intent intent) {
    // TODO Auto-generated method stub
    super.onNewIntent(intent);
    Log.e("TAP", "onNewIntent");
}

}

和AndroidManifest.xml

<activity android:name="com.example.detect.NfcTagDetector" >
        <intent-filter>
            <action android:name="android.nfc.action.TECH_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>

nfc_tech_filter.xml文件为

<resources xmlns:xliff="urn:oasis:names:tc:xliff:document:1.2">
<tech-list>
    <tech>android.nfc.tech.IsoDep</tech>

请帮助……

技术列表需要一个标签来匹配列表中的所有项目。这在你的清单上是不可能的。最好尝试：

<resources xmlns:xliff="urn:oasis:names:tc:xliff:document:1.2">
<tech-list>
    <tech>android.nfc.tech.NfcA</tech>
</tech-list>
<tech-list>
    <tech>android.nfc.tech.NfcB</tech>
</tech-list>
<tech-list>
    <tech>android.nfc.tech.NfcF</tech>
</tech-list>
<tech-list>
    <tech>android.nfc.tech.NfcV</tech>
</tech-list>
<tech-list>
    <tech>android.nfc.tech.Ndef</tech>

您要检测哪种类型的标签？我想问题可能在于你的“花生”是的，你是对的，你知道。。问题出在我的设备上。我在试三星S II，它的NFC有缺陷。。现在我试过Nexus，一切都正常了是的，你说得对。。最大的问题是，我在一个有缺陷的支持NFC的设备上测试代码。。谢谢nyways NFC的家伙+1.谢谢你的帮助。。
