使用Android studio编写读取NT3H2211芯片数据的程序

由于NT3H2211芯片是NFC芯片，因此需要使用相关的NFC API来读取芯片数据。以下是一个简单的Android Studio程序，可以读取NT3H2211芯片的NDEF数据：

1. 在build.gradle文件中添加以下依赖项：

dependencies {
    ...
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    implementation 'com.android.support:support-v4:28.0.0'
    implementation 'com.android.support:design:28.0.0'
    implementation 'com.android.support:cardview-v7:28.0.0'

    implementation 'com.android.support:support-core-ui:28.0.0'
    implementation 'com.android.support:support-core-utils:28.0.0'

    implementation 'com.android.support:support-annotations:28.0.0'
    implementation 'com.android.support:support-compat:28.0.0'
    implementation 'com.android.support:support-media-compat:28.0.0'
    implementation 'com.android.support:support-core-ui:28.0.0'
    implementation 'com.android.support:support-core-utils:28.0.0'
    implementation 'com.android.support:support-fragment:28.0.0'

    implementation 'com.android.support:customtabs:28.0.0'

    implementation 'com.android.support:support-vector-drawable:28.0.0'

    implementation 'com.google.android.material:material:1.1.0-alpha10'

    implementation 'com.android.support:multidex:1.0.3'

    implementation 'com.google.android.gms:play-services-nfc:17.0.0'

    ...
}

2. 在AndroidManifest.xml文件中添加以下权限：

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

3. 在MainActivity.java中添加以下代码：

public class MainActivity extends AppCompatActivity {

    private TextView mTextView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mTextView = findViewById(R.id.text_view);

        // 检查设备是否支持NFC
        NfcManager nfcManager = (NfcManager) getSystemService(Context.NFC_SERVICE);
        NfcAdapter nfcAdapter = nfcManager.getDefaultAdapter();
        if (nfcAdapter == null) {
            mTextView.setText("该设备不支持NFC！");
            return;
        }

        // 检查NFC是否启用
        if (!nfcAdapter.isEnabled()) {
            mTextView.setText("请启用NFC功能！");
            return;
        }

        // 设置NFC过滤器
        IntentFilter[] intentFilters = new IntentFilter[]{
                new IntentFilter(NfcAdapter.ACTION_NDEF_DISCOVERED),
                new IntentFilter(NfcAdapter.ACTION_TAG_DISCOVERED),
                new IntentFilter(NfcAdapter.ACTION_TECH_DISCOVERED)
        };
        String[][] techLists = new String[][]{
                new String[]{Ndef.class.getName()},
                new String[]{MifareClassic.class.getName()},
                new String[]{MifareUltralight.class.getName()},
                new String[]{NfcA.class.getName()},
                new String[]{NfcB.class.getName()},
                new String[]{NfcF.class.getName()},
                new String[]{NfcV.class.getName()}
        };
        nfcAdapter.enableForegroundDispatch(this, PendingIntent.getActivity(
                getApplicationContext(), 0, new Intent(getApplicationContext(), getClass()), 0),
                intentFilters, techLists);
    }

    @Override
    protected void onResume() {
        super.onResume();

        // 读取NFC标签数据
        Intent intent = getIntent();
        if (NfcAdapter.ACTION_NDEF_DISCOVERED.equals(intent.getAction())) {
            Parcelable[] rawMessages = intent.getParcelableArrayExtra(NfcAdapter.EXTRA_NDEF_MESSAGES);
            if (rawMessages != null) {
                NdefMessage[] messages = new NdefMessage[rawMessages.length];
                for (int i = 0; i < rawMessages.length; i++) {
                    messages[i] = (NdefMessage) rawMessages[i];
                }
                byte[] payload = messages[0].getRecords()[0].getPayload();
                String text = new String(payload);
                mTextView.setText(text);
            } else {
                mTextView.setText("该NFC标签没有NDEF数据！");
            }
        } else {
            mTextView.setText("请将NFC标签靠近设备！");
        }
    }
}

4. 在activity_main.xml中添加一个TextView：

<TextView
    android:id="@+id/text_view"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="请将NFC标签靠近设备！"
    android:textSize="20sp"
    android:textStyle="bold"
    android:layout_marginTop="32dp"
    android:gravity="center"/>

这个程序将在设备检测到NT3H2211芯片时读取芯片中的NDEF数据并在TextView中显示。请注意，您需要将NT3H2211芯片放在设备的NFC天线附近，以确保芯片得到读取。
