我是android的新手,我试图在收到新消息时获取短信的号码,我正在使用广播接收器。但当一条新消息传来时,我的“广播接收器”课程无效。任何人都可以帮我找出问题所在。在下面给我的代码..
public class MainActivity extends Activity
{
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.test_layout);
}
public class MyBroadcastReciever extends BroadcastReceiver
{
@Override
public void onReceive(Context context, Intent intent)
{
Bundle bundle = intent.getExtras();
SmsMessage[] msgs = null;
String smsnumber = "";
if (bundle != null)
{
//---retrieve the sender number SMS received---
Object[] pdus = (Object[]) bundle.get("pdus");
msgs = new SmsMessage[pdus.length];
for (int i=0; i<msgs.length; i++)
{
msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]);
smsnumber = msgs[i].getOriginatingAddress();
}
}
}
}
}
我已经在清单中给出了接收标签。
<receiver android:name="com.aucupa.iack.MyBroadcastReciever" >
<intent-filter>
<action android:name="android.provider.Telephony.SMS_RECEIVED" />
</intent-filter>
</receiver>
鉴于获得sms的使用许可..
<uses-permission android:name="android.permission.RECEIVE_SMS" />
但是当一个sms没有来自MyBroadcastReciever类的响应时。当我调试控件时,不会进入MyBroadcastReciever类。 PLZ帮我找出问题
最后我得到了你所有帮助的答案,在这里给出了答案..
public class MainActivity extends Activity
{
MyBroadcastReciever broadcastreciever = new MyBroadcastReciever();
static final String SOME_ACTION = "android.provider.Telephony.SMS_RECEIVED";
IntentFilter intentFilter = new IntentFilter(SOME_ACTION);
Intent i = new Intent(SOME_ACTION);
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.test_layout);
sendBroadcast(i);
context.registerReceiver(broadcastreciever, intentFilter);
}
public class MyBroadcastReciever extends BroadcastReceiver
{
@Override
public void onReceive(Context context, Intent intent)
{
if (intent.getAction() == "android.provider.Telephony.SMS_RECEIVED"){
Bundle bundle = intent.getExtras();
SmsMessage[] msgs = null;
String smsnumber = "";
if (bundle != null)
{
//---retrieve the sender number SMS received---
Object[] pdus = (Object[]) bundle.get("pdus");
msgs = new SmsMessage[pdus.length];
for (int i=0; i<msgs.length; i++)
{
msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]);
smsnumber = msgs[i].getOriginatingAddress();
}
}
}
}
}
}

在MyBroadcastReciever中扩展BroadcastReceiver,在onReceive()里面试试这段代码
if (intent.getAction() == android.provider.Telephony.SMS_RECEIVED) {
Bundle bundle = intent.getExtras();
if (bundle != null) {
// your rest of code
}
}

我认为问题在于注册/取消注册BroadcastReceiver
并删除了清单声明。
将ReceiveMessages
定义为Activity
中需要侦听来自Service
的消息的内部类。
然后,声明类变量,例如......
ReceiveMessages myReceiver = null;
Boolean myReceiverIsRegistered = false;
在onCreate()
中使用myReceiver = new ReceiveMessages();
然后在onResume()
...
if (!myReceiverIsRegistered) {
registerReceiver(myRecever, new IntentFilter("com.mycompany.myapp.SOME_MESSAGE"));
myReceiverIsRegistered = true;
}
...并在onPause()
...
if (myReceiverIsRegistered) {
unregisterReceiver(myReceiver);
myReceiverIsRegistered = false;
}
在Service
创建并广播Intent
...
Intent i = new Intent("com.mycompany.myapp.SOME_MESSAGE");
sendBroadcast(i);
就是这样。让“操作”对您的包/应用程序来说是唯一的,即com.mycompany...
,如我的示例所示。这有助于避免其他应用程序或系统组件可能尝试处理它的情况。

在清单中 使用此预设
<uses-permission android:name="android.permission.RECEIVE_SMS" />
<uses-permission android:name="android.permission.SEND_SMS" />
和
<receiver android:name="net.app.sms.MessageReceiver" >
<intent-filter>
<action android:name="android.provider.Telephony.SMS_RECEIVED" />
</intent-filter>
</receiver>
试试这个......
<强> EDITED 强>
<receiver android:name="Your PackageName.ClassName" >
<intent-filter>
<action android:name="android.provider.Telephony.SMS_RECEIVED" />
</intent-filter>
</receiver>

要接收定义的BroadcastReceiver的意图,您可以在AndroidManifest.xml中对接收器进行delcare,如下所示:
<receiver android:name="full qualified name of your receiver">
<action android:name="the action interests you"/>
</receiver>
或使用Context.registerReceiver注册它:
Context.registerReceiver(receiver, intentFilter);
否则,系统无法知道您的接收器是否存在。对于某些特殊的敏感意图(如SMS),您还需要在AndroidManifest.xml中使用delcare权限。

尝试清理并重建代码。有时我们需要在更新代码时进行清理。
你必须双向注册。
静态和动态
您可以看到更多信息link。
或强>
Uri uriSMSURI = Uri.parse("content://sms/");
Cursor cur = mContext.getContentResolver().query(uriSMSURI, null, null,null, null);
cur.moveToFirst();
id = cur.getString(cur.getColumnIndex("thread_id"));
protocol = cur.getString(cur.getColumnIndex("protocol"));
Long date=cur.getLong(cur.getColumnIndex("date"));
type = cur.getInt(cur.getColumnIndex("type"));
String address=cur.getString(cur.getColumnIndex("address"));
System.out.println("READING LOG...."+"\n thread_id:"+id+"\n protocol:"+protocol+"\n type:"+type+"\n address"+address);
if(protocol==null && (type==2 || type==4 || type==6)){
Log.i("======TEST====", "MESSAGE SENT.......number:"+address);
}else if(protocol!=null && type==1){
Log.i("======TEST====", "MESSAGE RECEIVE.......number:"+address);
}else{
//something message
}
尝试这个。
