【Android】_SmsReceicer_短信监听

一、新建Receiver并赋予权限

• 新建SmsReceiver继承BroadcastReceiver：
  
• 赋予权限

<uses-permission android:name="android.permission.RECEIVE_SMS" /> <!-- 接收短信权限 -->
<uses-permission android:name="android.permission.READ_SMS" /> <!-- 读取短信权限 -->
   .......略..........
       <receiver
            android:name=".SmsReceiver"
            android:enabled="true"
            android:exported="true" >
            <intent-filter android:priority="123" >
                <action android:name="android.provider.Telephony.SMS_RECEIVED" />
            </intent-filter>
        </receiver>

二、新建activity.xml和SmsActivity.java
xml：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:background="@color/colorPrimary"
    tools:context=".SmsActivity">
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="监听到短信内容：                "
        android:layout_marginTop="20dp"
        android:textSize="20sp"
        android:textColor="#ffffff"/>
    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="20dp"
        android:gravity="center_horizontal"
        android:id="@+id/text"
        />
</LinearLayout>

• java

package com.example.cungu.myapplication4;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.TextView;

public class SmsActivity extends AppCompatActivity {
    public static TextView textView;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_sms);
        textView=findViewById(R.id.text);
    }
}

三、编辑自定义SmsReceiver.java：
把内容显示到上面创建的textView中：

package com.example.cungu.myapplication4;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsMessage;
import android.util.Log;

import java.text.SimpleDateFormat;
import java.util.Date;

import static com.example.cungu.myapplication4.SmsActivity.textView;

public class SmsReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        Bundle bundle = intent.getExtras();
        SmsMessage msg = null;
        if (null != bundle) {
            Object[] smsObj = (Object[]) bundle.get("pdus");
            for (Object object : smsObj) {
                msg = SmsMessage.createFromPdu((byte[]) object);
                Date date = new Date(msg.getTimestampMillis());// 时间
                SimpleDateFormat format = new SimpleDateFormat(
                        "yyyy-MM-dd HH:mm:ss");
                String receiveTime = format.format(date);
                Log.i("接收", "address:" + msg.getOriginatingAddress()
                        + "   body:" + msg.getDisplayMessageBody() + "  time:"
                        + msg.getTimestampMillis());
                textView.append("接收到短信来自：\n"+msg.getOriginatingAddress()+"\n内容：\n"+msg.getDisplayMessageBody()+"\n时间：\n+"+ receiveTime);
            }
        }
    }
}

最终效果：
我向10010发送一条查询短信后：
