22 接受收到短信广播

• 权限:

<uses-permission android:name="android.permission.RECEIVE_SMS"/>

意图

 <!-- 短信的广播Action -->
        <receiver android:name=".MySmsReceiver">
            <intent-filter >
                <action android:name="android.provider.Telephony.SMS_RECEIVED"/>
            </intent-filter>
        </receiver>

结构:

MainActivity.java

package com.qf.day22_broadcastreceiver_demo8;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

}

MySmsReceiver.java

补充说明:因为当你发一条短信140个字符(70汉子)以上时会分为两条短息发送 所以收到是数组
SmsMessage.createFromPdu((byte[])pdus[i]) 在API23过时
