安卓通过广播自动回填短信验证码

每次我们注册一个什么软件的账号时一般都是需要输入

验证码的，然后验证码需要通过短信的接收才可以看得到

那么问题来了。短信接收到，我们可以直接将验证码填入

需要填入的输入框里面去。

接下来贴代码时刻

声明部分

private BroadcastReceiver smsReceiver;// 定义一个广播接收器private IntentFilter filter2;//private EditText editCaptcha;// 短信自动填入框private String strContent; // 验证码内容private String patternCoder = "(?<!\\d)\\d{4,10}(?!\\d)";// 验证短信内容

代码实现部分

private Handler handler = new Handler() {public void handleMessage(android.os.Message msg) {editCaptcha.setText(strContent);};};@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);editCaptcha = (EditText) findViewById(R.id.login_editcaptcha);filter2 = new IntentFilter();// 创建意图过滤器filter2.addAction("android.provider.Telephony.SMS_RECEIVED");// 创建意图动作filter2.setPriority(Integer.MAX_VALUE);// 设置等级最大smsReceiver = new BroadcastReceiver() {@Overridepublic void onReceive(Context context, Intent intent) {Object[] objs = (Object[]) intent.getExtras().get("pdus");// 获取收到的消息for (Object obj : objs) {byte[] pdu = (byte[]) obj;SmsMessage sms = SmsMessage.createFromPdu(pdu);// 短信的内容String message = sms.getMessageBody();// 获取手机短信的内容Log.d("logo", "message " + message);// 短息的手机号。。+86开头？String from = sms.getOriginatingAddress();// 获取手机号码Toast.makeText(getApplicationContext(), "from: " + from,Toast.LENGTH_LONG).show();Log.d("logo", "from " + from);if (!TextUtils.isEmpty(from)) {// 判断号码是否为空String code = patternCode(message);if (!TextUtils.isEmpty(code)) {strContent = code;handler.sendEmptyMessage(1);}}}}};registerReceiver(smsReceiver, filter2);// 注册广播监听器}@Overrideprotected void onDestroy() {super.onDestroy();// 解除自动输入的广播unregisterReceiver(smsReceiver);}/** * 匹配短信中间的6个数字（验证码等） * * @param patternContent * @return */private String patternCode(String patternContent) {if (TextUtils.isEmpty(patternContent)) {return null;}Pattern p = Pattern.compile(patternCoder);Matcher matcher = p.matcher(patternContent);if (matcher.find()) {return matcher.group();}return null;}

另外重要的是我们要给我们的程序清单文件给个权限

<!-- 短信接收权限 --> <uses-permission android:name="android.permission.RECEIVE_SMS"> </uses-permission>

那么我们的软件就可以自动回填数据了!!!
