* 1.自定义监听类*
/**
* 短信**，用于自动填充验证码
*/
public class SMSContentObserver extends ContentObserver {
public final String SMS_URI_INBOX = "content://sms/inbox";//收信箱
private Activity activity = null;
private String smsContent = "";//验证码
private EditText verifyText = null;//验证码编辑框
private String SMS_ADDRESS_PRNUMBER = "10690329013589";//短息发送提供商
private String smsID = "";
//短信观察者 收到一条短信时 onchange方法会执行两次，所以比较短信id，如果一致则不处理
public SMSContentObserver(Activity activity, Handler handler, EditText verifyText) {
super(handler);
this.activity = activity;
this.verifyText = verifyText;
}
@Override
public void onChange(boolean selfChange) {
super.onChange(selfChange);
Cursor cursor = null;// 光标
// 读取收件箱中指定号码的短信
cursor = activity.getContentResolver().query(Uri.parse(SMS_URI_INBOX),
new String[]{"_id", "address", "body", "read"}, //要读取的属性
"address=? and read=?", //查询条件是什么
new String[]{SMS_ADDRESS_PRNUMBER, "0"},//查询条件赋值
"date desc");//排序
if (cursor != null) {
cursor.moveToFirst();
if (cursor.moveToFirst()) {
//比较和上次接收到短信的ID是否相等
if (!smsID.equals(cursor.getString(cursor.getColumnIndex("_id")))) {
String smsbody = cursor.getString(cursor.getColumnIndex("body"));
//用正则表达式匹配验证码
Pattern pattern = Pattern.compile("[0-9]{6}");
Matcher matcher = pattern.matcher(smsbody);
if (matcher.find()) {//匹配到6位的验证码
smsContent = matcher.group();
if (verifyText != null && null != smsContent && !"".equals(smsContent)) {
verifyText.requestFocus();//获取焦点
verifyText.setText(smsContent);//设置文本
verifyText.setSelection(smsContent.length());//设置光标位置
}
}
smsID = cursor.getString(cursor.getColumnIndex("_id"));
}
}
}
}
} 2.在登录页面事件化监听类
Java代码
//实例化短信**
SMSContentObserver mObserver = new SMSContentObserver(getActivity(), new Handler(), mEt_auth_code);
// 注册短信变化监听
mContext.getContentResolver().registerContentObserver(Uri.parse("content://sms/"), true, mObserver); > 3.声明读取短信权限
<uses-permission android:name="android.permission.RECEIVE_SMS" />
<uses-permission android:name="android.permission.READ_SMS" />
<uses-permission android:name="android.permission.WRITE_SMS" /> 4.为了防止内存泄漏，记得注销监听
Java代码
@Override
public void onDestroy() {
super.onDestroy();
//注销短信监听
mContext.getContentResolver().unregisterContentObserver(mObserver);
}
小结：
去短信库获取短信比较不容易被拦截
