1、首先我们要写一个广播接收器，当我们的手机收到短信时，系统会自动发送一个广播，我们只需要接收到这条广播就可以了
2、在广播里面，我们重写的onReceive（）方法，通过里面的Intent写到的Bundle就可以拿到短信的内容，
3、清单文件里面我们必须要添加权限，否则无法接收到。
4、为了防止我们的广播接收不到，我们自己写的广播接收器的权限必须要大，以防万一，我设置了1000。
下面上代码，里面的注释也比较详细..
<?xml version="." encoding="utf-"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.fanlei.cutnotedemo" >
//接收短信
<uses-permission android:name="android.permission.RECEIVE_SMS"/>
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<!-- action:name = 的名称是固定的 -->
<receiver android:name=".NoteReceiver">
<intent-filter android:priority="">
<action android:name="android.provider.Telephony.SMS_RECEIVED"/>
</intent-filter>
</receiver>
<activity
android:name=".MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
写一个类，继承BroadcastReceiver
Android--获取短信的内容，截取短信
package com.example.fanlei.cutnotedemo;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsMessage;
import android.widget.Toast;
import java.text.SimpleDateFormat;
import java.util.Date;
/**
* 广播接收器
*/
public class NoteReceiver extends BroadcastReceiver {
private static final String SMS_RECEIVED_ACTION = "android.provider.Telephony.SMS_RECEIVED";
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
//判断广播消息
if (action.equals(SMS_RECEIVED_ACTION)){
Bundle bundle = intent.getExtras();
//如果不为空
if (bundle != null){
//将pdus里面的内容转化成Object[]数组
Object pdusData[] = (Object[]) bundle.get("pdus");
//解析短信
SmsMessage[] msg = new SmsMessage[pdusData.length];
for (int i = ;i < msg.length;i++){
byte pdus[] = (byte[]) pdusData[i];
msg[i] = SmsMessage.createFromPdu(pdus);
}
StringBuffer content = new StringBuffer();//获取短信内容
StringBuffer phoneNumber = new StringBuffer();//获取地址
StringBuffer receiveData = new StringBuffer();//获取时间
//分析短信具体参数
for (SmsMessage temp : msg){
content.append(temp.getMessageBody());
phoneNumber.append(temp.getOriginatingAddress());
receiveData.append(new SimpleDateFormat("yyyy-MM-dd hh:mm:ss.SSS")
.format(new Date(temp.getTimestampMillis())));
}
/**
* 这里还可以进行好多操作，比如我们根据手机号进行拦截（取消广播继续传播）等等
*/
Toast.makeText(context,phoneNumber.toString()+content+receiveData, Toast.LENGTH_LONG).show();//短信内容
}
}
}
}
ps：android获取短信所有内容
public class GetMessageInfo {
List<MessageInfo> list;
Context context;
MessageInfo messageInfo;
public GetMessageInfo(Context context) {
list = new ArrayList<MessageInfo>();
this.context = context;
}
// --------------------------------收到的短息信息----------------------------------
public List<MessageInfo> getSmsInfos() {
final String SMS_URI_INBOX = "content://sms/inbox";// 收信箱
try {
ContentResolver cr = context.getContentResolver();
String[] projection = new String[] { "_id", "address", "person","body", "date", "type" };
Uri uri = Uri.parse(SMS_URI_INBOX);
Cursor cursor = cr.query(uri, projection, null, null, "date desc");
while (cursor.moveToNext()) {
messageInfo = new MessageInfo();
// -----------------------信息----------------
int nameColumn = cursor.getColumnIndex("person");// 联系人姓名列表序号
int phoneNumberColumn = cursor.getColumnIndex("address");// 手机号
int smsbodyColumn = cursor.getColumnIndex("body");// 短信内容
int dateColumn = cursor.getColumnIndex("date");// 日期
int typeColumn = cursor.getColumnIndex("type");// 收发类型 1表示接受 2表示发送
String nameId = cursor.getString(nameColumn);
String phoneNumber = cursor.getString(phoneNumberColumn);
String smsbody = cursor.getString(smsbodyColumn);
Date d = new Date(Long.parseLong(cursor.getString(dateColumn)));
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd " + "\n" + "hh:mm:ss");
String date = dateFormat.format(d);
// --------------------------匹配联系人名字--------------------------
Uri personUri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI,phoneNumber);
Cursor localCursor = cr.query(personUri, new String[] {PhoneLookup.DISPLAY_NAME, PhoneLookup.PHOTO_ID,PhoneLookup._ID }, null, null, null);
System.out.println(localCursor.getCount());
System.out.println("之前----"+localCursor);
if (localCursor.getCount()!=0) {
localCursor.moveToFirst();
System.out.println("之后----"+localCursor);
String name = localCursor.getString(localCursor.getColumnIndex(PhoneLookup.DISPLAY_NAME));
long photoid = localCursor.getLong(localCursor.getColumnIndex(PhoneLookup.PHOTO_ID));
long contactid = localCursor.getLong(localCursor.getColumnIndex(PhoneLookup._ID));
messageInfo.setName(name);
// 如果photoid 大于0 表示联系人有头像 ，如果没有给此人设置头像则给他一个默认的
if (photoid > 0) {
Uri uri1 = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI,contactid);
InputStream input = ContactsContract.Contacts.openContactPhotoInputStream(cr, uri1);
messageInfo.setContactPhoto(BitmapFactory.decodeStream(input));
} else {
messageInfo.setContactPhoto(BitmapFactory.decodeResource(context.getResources(),R.drawable.ic_launcher));
}
}else{
messageInfo.setName(phoneNumber);
messageInfo.setContactPhoto(BitmapFactory.decodeResource(context.getResources(), R.drawable.ic_launcher));
}
localCursor.close();
messageInfo.setSmsContent(smsbody);
messageInfo.setSmsDate(date);
list.add(messageInfo);
}
} catch (SQLiteException e) {
e.printStackTrace();
}
return list;
}
}
