我正在尝试创建一个应用程序来计算来自手机的外发短信的数量.目前我有以下代码：
private void listenForSMS(){
Log.v("SMSTEST","STARTED LISTENING FOR SMS OUTGOING");
Handler handle = new Handler(){};
SMSObserver myObserver = new SMSObserver(handle);
ContentResolver contentResolver = getContentResolver();
contentResolver.registerContentObserver(Uri.parse("content://sms"),true,myObserver);
}
private class SMSObserver extends ContentObserver{
int count = 0;
String lastMessage = null;
public SMSObserver(Handler handler) {
super(handler);
}
public void onChange(boolean selfChange) {
super.onChange(selfChange);
Log.v("SMSTEST","HIT ON CHANGE");
Uri uriSMSURI = Uri.parse("content://sms");
Cursor cur = getContentResolver().query(uriSMSURI,null,null);
cur.moveToNext();
String protocol = cur.getString(cur.getColumnIndex("protocol"));
if(protocol == null){
count++;
Log.v("SMSTEST","SMS SENT: count: " + count);
String content = cur.getString(cur.getColumnIndex("body"));
}else{
Log.v("SMSTEST","SMS RECIEVED");
}
}
}
当我发送一页短信时,onChange被调用3次.当我发送两页短信时,onChange被调用4次. 3页留言,被叫5次;等等.
注意：我已经尝试过Uri.parse的其他变体(“content：// sms”),例如“content：// sms / sent”,除了“content：// sms”之外没有任何变化可以调用.
如何唯一地区分外发短信并准确计算发送的短信数量？
