先说一句：MIUI请放弃治疗！这里给个传送门：

识别短信验证码并提取还是挺常见的一个需求。所要解决的问题主要有：

1、如何监听

2、如何提取短信中的验证码

3、监听多次调用问题

直接看下面代码吧，很明了。需要注意的点有就是onChange会多次调用。其实打Log就看的出了，收到一条短信会调用两次onChange，Log结果如下：

mUri===content://sms/raw/20

mUri===content://sms/inbox/20

安卓7.0以上系统，点击标记为已读，也会调用一次

mUri===content://sms

收到一条短信都是uri后面都会有确定的一个数字，对应数据库的_id，比如上面的20

public static class SMSCodeObserver extends ContentObserver {

private Activity mActivity;

private static final String TAG = "SMSCodeObserver";

private SMSCodeListener mSMSCodeListener;

private Uri mUri;

public void setSMSCodeListener(SMSCodeListener SMSCodeListener) {

mSMSCodeListener = SMSCodeListener;

}

public interface SMSCodeListener {

void onResult(String code);

}

public SMSCodeObserver(Handler handler, Activity activity) {

super(handler);

mActivity = activity;

}

public void register() {

mActivity.getContentResolver().registerContentObserver(

Uri.parse("content://sms/"), true, this);

}

public void unRegister() {

mActivity.getContentResolver().unregisterContentObserver(this);

}

@Override

public void onChange(boolean selfChange, Uri uri) {

super.onChange(selfChange, uri);

if (uri == null) {

mUri = Uri.parse("content://sms/inbox");

} else {

mUri = uri;

}

if (mUri.toString().contains("content://sms/raw") || mUri.toString().equals("content://sms")) {

return;

}

LogUtils.d(TAG, "mUri===" + mUri.toString());

AndPermission.with(mActivity)

.permission(Manifest.permission.READ_SMS)

.requestCode(100)

.callback(this)

.rationale(new RationaleListener() {

@Override

public void showRequestPermissionRationale(int requestCode, Rationale rationale) {

AndPermission.rationaleDialog(mActivity, rationale)

.show();

}

})

.start();

}

@PermissionYes(100)

@SuppressWarnings("unused")

private void getPermissionYes(List grantedPermissions) {

handleSMS();

}

@PermissionNo(100)

@SuppressWarnings("unused")

private void getPermissionNo(List deniedPermissions) {

if (AndPermission.hasPermission(mActivity, Manifest.permission.READ_SMS)) {

handleSMS();

} else {

AndPermission.defaultSettingDialog(mActivity)

.show();

}

}

private void handleSMS() {

/* 按照日期倒序排序 */

Cursor cursor = mActivity.getContentResolver().query(mUri, null, null, null, "date desc");

if (cursor != null) {

if (cursor.moveToFirst()) {//游标移动到first位置

/* 发件人的号码 */

String address = cursor.getString(cursor.getColumnIndex("address"));

/* 短信内容 */

String body = cursor.getString(cursor.getColumnIndex("body"));

LogUtils.d(TAG, "address:" + address + ",body:" + body);

if (!body.contains("验证码")) {

return;

}

/* 利用正则提取验证码(根据实际情况修改) */

String code = getSMSCode(body);

if (code != null) {

if (mSMSCodeListener != null) {

mSMSCodeListener.onResult(code);

}

LogUtils.d(TAG, "code:" + code);

}

}

cursor.close();

}

}

private static String getSMSCode(String msg) {

/*提取正则表达式，需按需修改*/

Pattern p = Pattern.compile("(?

Matcher m = p.matcher(msg);

if (m.find()) {

LogUtils.d(TAG, m.group());

return m.group(0);

}

return null;

}

}
