1、申請權限

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

API>23動態申請權限

private static final String[] authBaseArr = {//申請類型Manifest.permission.RECEIVE_SMS,Manifest.permission.READ_SMS, }; private static final int authBaseRequestCode = 1; private boolean hasBasePhoneAuth() {PackageManager pm = getPackageManager();for (String auth : authBaseArr) {if (pm.checkPermission(auth, getPackageName()) != PackageManager.PERMISSION_GRANTED) {return false;}}return true; }private void initNavi() {// 申請權限if (android.os.Build.VERSION.SDK_INT >= 23) {if (!hasBasePhoneAuth()) {this.requestPermissions(authBaseArr, authBaseRequestCode);return;}} }

2、自定義ContentObserver

/*** 作者：created by meixi* 郵箱：1085220040@qq.com* 日期：2019/12/11 17:37*/ public class SmsObserver extends ContentObserver {private Context mContext;private Handler mHandler;private int mReceivedCode = 1;public SmsObserver(Context context, Handler handler, int received_code) {super(handler);mContext = context;mHandler = handler;mReceivedCode = received_code;}@Overridepublic void onChange(boolean selfChange, Uri uri) {super.onChange(selfChange, uri);String code = "";if (uri.toString().equals("content://sms/raw")) {return;}Uri inboxUri = Uri.parse("content://sms/inbox");final String[] projection = new String[]{"address", "body"};Cursor c = mContext.getContentResolver().query(inboxUri, projection, "read=?", new String[]{"0"}, "date desc"); // Cursor c = mContext.getContentResolver().query(inboxUri, null, null, null, "date desc");if (c != null) {if (c.moveToFirst()) {String address = c.getString(c.getColumnIndex("address"));String body = c.getString(c.getColumnIndex("body"));LgqLogutil.e("發件人為：" + address + "》》》》短信內容為：" + body);Pattern pattern = Pattern.compile("(\\d{4,6})");Matcher matcher = pattern.matcher(body);if (matcher.find()) {code = matcher.group(0);LgqLogutil.e("驗證碼》》》" + code);ClipboardManager cmb = (ClipboardManager) mContext.getSystemService(Context.CLIPBOARD_SERVICE);cmb.setText(code);mHandler.obtainMessage(mReceivedCode, code).sendToTarget();}}c.close();}} }

3、activity實現代碼

private Handler mHandler = new Handler() {@Overridepublic void handleMessage(Message msg) {if (msg.what == 1) {String code = (String) msg.obj;Log.e("lgq","短信===="+code); // mEtUserVerificationCode.setText(code);//填充}}}; SmsObserver mObserver = new SmsObserver(this, mHandler, 1);Uri uri = Uri.parse("content://sms"); getContentResolver().registerContentObserver(uri, true, mObserver);

附：獲取首條短信

String code = "";// Uri inboxUri = Uri.parse("content://sms/inbox");Uri inboxUri = Uri.parse("content://sms");Cursor c = getContentResolver().query(inboxUri, null, null, null, "");if (c != null) {if (c.moveToFirst()) { // if (c.moveToNext()) {String address = c.getString(c.getColumnIndex("address"));String body = c.getString(c.getColumnIndex("body"));LgqLogutil.i("main發件人為：" + address + "》》》》短信內容為：" + body);Pattern pattern = Pattern.compile("(\\d{4,6})");Matcher matcher = pattern.matcher(body);if (matcher.find()) {code = matcher.group(0);LgqLogutil.e("main驗證碼》》》" + code);ClipboardManager cmb = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);cmb.setText(code);mHandler.obtainMessage(mReceivedCode, code).sendToTarget();}}c.close();}

注：有這個防護標志的，會獲取失敗
