MainActivity

extends

AppCompatActivity

{

public

content;

@Override

void

onCreate(Bundle

savedInstanceState)

{

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

if

(this.checkSelfPermission(Manifest.permission.READ_SMS)

!=

PackageManager.PERMISSION_GRANTED)

{

//申请READ_SMS权限

ActivityCompat.requestPermissions(this,new

String[]{Manifest.permission.READ_SMS},

1);

}

mText

=

(TextView)

findViewById(R.id.text);

content

=

new

SmsContent(new

Handler(),this);

//注册短信变化监听

this.getContentResolver().registerContentObserver(Uri.parse("content://sms/"),

true,

content);

}

@Override

protected

void

onDestroy()

{

super.onDestroy();

this.getContentResolver().unregisterContentObserver(content);

}

@Override

public

void

onRequestPermissionsResult(int

requestCode,

@NonNull

String[]

permissions,

@NonNull

int[]

grantResults)

{

super.onRequestPermissionsResult(requestCode,

permissions,

doNext(requestCode,grantResults);

}

if

(requestCode

==

{

if

(grantResults[0]

==

PackageManager.PERMISSION_GRANTED)

}

else

}

}

}

}SmsContentclass

extends

{

private

Cursor

cursor

=

null;

private

Context

context;

public

SmsContent(Handler

handler,Context

context)

{

super(handler);

this.context

=

context;

}

@Override

public

void

onChange(boolean

selfChange)

{

super.onChange(selfChange);

Log.i("SMSTest","Begin");

//读取收件箱中指定号码的短信

//

cursor

=

context.getContentResolver().query(Uri.parse("content://sms/inbox"),

new

String[]{"_id",

"address",

"read",

"body"},

//

"

address=?

and

read=?",

new

String[]{"10086",

"0"},

"_id

desc");//按id排序，如果按date排序的话，修改手机时间后，读取的短信就不准了

cursor

=

context.getContentResolver().query(Uri.parse("content://sms/inbox"),

new

String[]{"_id",

"address",

"read",

"body"},

null,

null,

"_id

desc");

Log.i("SMSTest","cursor.isBeforeFirst():

"

+

cursor.isBeforeFirst()

+

"

cursor.getCount():

"

+

cursor.getCount());

if

(cursor

!=

null

&&

cursor.getCount()

>

0)

{

cursor.moveToFirst();

int

smsbodyColumn

=

cursor.getColumnIndex("body");

String

smsBody

=

cursor.getString(smsbodyColumn);

Log.i("SMSTest","smsBody

=

"

+

smsBody);

MainActivity.mText.setText(getDynamicPassword(smsBody));

}

//在用managedQuery的时候，不能主动调用close()方法，

否则在Android

4.0+的系统上，

会发生崩溃

if(Build.VERSION.SDK_INT

<

14)

{

cursor.close();

}

}

public

static

String

getDynamicPassword(String

str)

{

Pattern

continuousNumberPattern

=

Ppile("[0-9\\.]+");

Matcher

m

=

continuousNumberPattern.matcher(str);

String

dynamicPassword

=

"";

while(m.find()){

if(m.group().length()

==

6)

{

System.out.print(m.group());

dynamicPassword

=

m.group();

}

}

return

dynamicPassword;

}

}上述方法未读短信多了之后会同时上传2条验证码信息，可以根据cursor.getCount()来控制下。。。下面第二种方法在oppor9s上不见效果。。各位使用的小伙伴注意哦public
