Question

我可以使用TelephonyManager来获取用户的电话接线员，我需要使用此名称来检索从运营商处收到的文本。如何在Android的ContextResolver.query（）方法中使用类似SQL where子句的内容？这是我的代码，用于检索用户收到的所有短信。我需要调整它以检索来自用户电话接线员的消息。

public void fetchSMS() {

    TelephonyManager tMgr = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
    String operator=tMgr.getNetworkOperatorName();
    Uri mSmsinboxQueryUri = Uri.parse("content://sms/inbox");
    String[] cols = new String[]{"_id", "thread_id", "address", "person", "date", "body", "type"};
    Cursor cursor1 = getContentResolver().query(
            mSmsinboxQueryUri,
            cols, null, null, null);
    if (cursor1!=null && cursor1.moveToFirst()) {
        do {
            String address = cursor1.getString(cursor1
                    .getColumnIndex(cols[2]));
            //String address2=(address.split("-"))[1];

                String date = cursor1.getString(cursor1
                        .getColumnIndex(cols[4]));
                String msg = cursor1.getString(cursor1
                        .getColumnIndex(cols[5]));
                String type = cursor1.getString(cursor1
                        .getColumnIndex(cols[6]));

                smsLog.append("\n" + "Address:").append(address).append("\n" + "Date:").append(date).append("\n" + "Message:").append(msg).append("\n" + "Type:").append(type).append("\n\n");
            cursor1.moveToNext();
        }
        while (!cursor1.isAfterLast());
        cursor1.close();
    }
}

<强> SmsBroadcastReceiver.java

这是一个BroadcastReceiver，它接收意图过滤的SMS消息。 onReceive，我们提取SMS消息包并显示Toast消息，并通过将SMS消息添加到SMS收件箱列表来更新UI。当短信到达时，收件箱会自动刷新。

public class SmsBroadcastReceiver extends BroadcastReceiver {

    public static final String SMS_BUNDLE = "pdus";

    public void onReceive(Context context, Intent intent) {
        Bundle intentExtras = intent.getExtras();
        if (intentExtras != null) {
            Object[] sms = (Object[]) intentExtras.get(SMS_BUNDLE);
            String smsMessageStr = "";
            for (int i = 0; i < sms.length; ++i) {
                SmsMessage smsMessage = SmsMessage.createFromPdu((byte[]) sms[i]);

                String smsBody = smsMessage.getMessageBody().toString();
                String address = smsMessage.getOriginatingAddress();

                smsMessageStr += "SMS From: " + address + "\n";
                smsMessageStr += smsBody + "\n";
            }
            Toast.makeText(context, smsMessageStr, Toast.LENGTH_SHORT).show();

            //this will update the UI with message
            SmsActivity inst = SmsActivity.instance();
            inst.updateList(smsMessageStr);
        }
    }
}

<强> SmsActivity.java 这是SMS应用程序的主要Android活动。它充当SMS收件箱。它有一个ListView来显示SMS消息。 onCreate我们从其Uri中读取内部SMS收件箱中的所有消息，并使用ListView显示它们。

public class SmsActivity extends Activity implements OnItemClickListener {

    private static SmsActivity inst;
    ArrayList<String> smsMessagesList = new ArrayList<String>();
    ListView smsListView;
    ArrayAdapter arrayAdapter;

    public static SmsActivity instance() {
        return inst;
    }

    @Override
    public void onStart() {
        super.onStart();
        inst = this;
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_sms);
        smsListView = (ListView) findViewById(R.id.SMSList);
        arrayAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, smsMessagesList);
        smsListView.setAdapter(arrayAdapter);
        smsListView.setOnItemClickListener(this);

        refreshSmsInbox();
    }

    public void refreshSmsInbox() {
        ContentResolver contentResolver = getContentResolver();
        Cursor smsInboxCursor = contentResolver.query(Uri.parse("content://sms/inbox"), null, null, null, null);
        int indexBody = smsInboxCursor.getColumnIndex("body");
        int indexAddress = smsInboxCursor.getColumnIndex("address");
        if (indexBody < 0 || !smsInboxCursor.moveToFirst()) return;
        arrayAdapter.clear();
        do {
            String str = "SMS From: " + smsInboxCursor.getString(indexAddress) +
                    "\n" + smsInboxCursor.getString(indexBody) + "\n";
            arrayAdapter.add(str);
        } while (smsInboxCursor.moveToNext());
    }

    public void updateList(final String smsMessage) {
        arrayAdapter.insert(smsMessage, 0);
        arrayAdapter.notifyDataSetChanged();
    }

    public void onItemClick(AdapterView<?> parent, View view, int pos, long id) {
        try {
            String[] smsMessages = smsMessagesList.get(pos).split("\n");
            String address = smsMessages[0];
            String smsMessage = "";
            for (int i = 1; i < smsMessages.length; ++i) {
                smsMessage += smsMessages[i];
            }

            String smsMessageStr = address + "\n";
            smsMessageStr += smsMessage;
            Toast.makeText(this, smsMessageStr, Toast.LENGTH_SHORT).show();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
