應用中通常會涉及到讀取短信，下面通過自動獲取短信驗證碼演示了如何在應用中讀取短信。

權限

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

通過廣播監聽短信

注意：這種方式只有在新接收到消息的時候才會執行代碼，并不會讀取收件箱中已讀或未讀的消息。

class SmsReceiver extends BroadcastReceiver {private OnSmsCatchListener mCallback;private String mPhoneNumber;private String mFilterRegex;public void setCallback(OnSmsCatchListener<String> callback) {this.mCallback = callback;}@Overridepublic void onReceive(Context context, Intent intent) {final Bundle bundle = intent.getExtras();try {if (bundle != null) {final Object[] pdusObj = (Object[]) bundle.get("pdus");for (int i = 0; i < pdusObj.length; i++) {SmsMessage currentMessage = getIncomingMessage(pdusObj[i], bundle);String phoneNumber = currentMessage.getDisplayOriginatingAddress();if (mPhoneNumber != null && !mPhoneNumber.equals(phoneNumber)) {return;}String message = currentMessage.getDisplayMessageBody();if (mFilterRegex != null && !message.matches(mFilterRegex)) {return;}if (mCallback != null) {mCallback.onSmsCatch(message);}}}} catch (Exception e) {}}private SmsMessage getIncomingMessage(Object aObject, Bundle bundle) {SmsMessage currentSMS;if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {String format = bundle.getString("format");currentSMS = SmsMessage.createFromPdu((byte[]) aObject, format);} else {currentSMS = SmsMessage.createFromPdu((byte[]) aObject);}return currentSMS;}public void setPhoneNumber(String phoneNumber) {this.mPhoneNumber = phoneNumber;}public void setFilterRegex(String regex) {this.mFilterRegex = regex;}public interface OnSmsCatchListener {void onSmsCatch(String message);} }

接下來注冊廣播：

SmsReceiver receiver = new SmsReceiver(); receiver.setCallback(onSmsCatchListener); receiver.setPhoneNumber(phoneNumber); receiver.setFilterRegex(regex); IntentFilter filter = new IntentFilter(); filter.addAction("android.provider.Telephony.SMS_RECEIVED"); activity.registerReceiver(receiver, filter);

最后在onStop/onDestroy中取消注冊：activity.unregisterReceiver(receiver)。

注意：系統這個廣播是有序廣播，當其他應用程序先獲取到了這個廣播再傳遞給你，如果廣播在其他應用程序中被注銷了就接收不到了。通過設置priority的數值，其實有時是不管用的，現在在一些定制的系統或是有安全軟件的情況下，短信往往都會被截取并注銷掉廣播監聽。

通過ContentObserver監聽短信

注意：這種方式可以獲取手機上所有的短信，包括已讀未讀的短信

public class SmsObserver extends ContentObserver {private OnSmsCatchListener mCatchListener;private String mPhoneNumberFilter;private String mSmsCatchRegex;private WeakReference<Activity> mActivityRef;public void setCallback(OnSmsCatchListener listener) {this.mCatchListener = listener;}public SmsObserver(Activity activity, Handler handler) {super(handler);mActivityRef = new WeakReference<Activity>(activity);}@Overridepublic void onChange(boolean selfChange) {super.onChange(selfChange);if (null == mCatchListener || null == mActivityRef.get()) {return;}Cursor cursor = null;try {final Uri uri = Uri.parse("content://sms/");final String[] projection = new String[]{"address", "body"};cursor = mActivityRef.get().getContentResolver().query(uri, projection, "read=?", new String[]{"0"}, "date desc");if (cursor.moveToFirst()) {do {final String address = cursor.getString(cursor.getColumnIndex("address"));if (!TextUtils.isEmpty(mPhoneNumberFilter) && !mPhoneNumberFilter.equals(address)) {Pattern p = Pattern.compile(mPhoneNumberFilter);Matcher m = p.matcher(address);if (!m.matches()) {return;}}final String message = cursor.getString(cursor.getColumnIndex("body"));if (!TextUtils.isEmpty(mSmsCatchRegex)) {Pattern p = Pattern.compile(mSmsCatchRegex);Matcher m = p.matcher(message);if (m.find()) {mCatchListener.onSmsCatch(m.group(0));return;}}} while (cursor.moveToNext());}} catch (Exception e) {} finally {if (cursor != null) {cursor.close();}}}/*** 手機號碼過濾** @param filter 手機號或者手機號正則表達式*/public void setPhoneNumberFilter(String filter) {this.mPhoneNumberFilter = filter;}public void setSmsCatchRegex(String regex) {this.mSmsCatchRegex = regex;} }

然后通過getContentResolver().registerContentObserver(Uri.parse(“content://sms/”), true, mSmsObserver)注冊監聽。

最后通過getContentResolver().unregisterContentObserver(mSmsObserver)注銷監聽。
