我试图从收件箱中隐藏一些消息,然后转身并将其放置在一个新数据库中....我的代码为 SmsFilter.java 如下
public class SmsFilter extends BroadcastReceiver{
SQLiteDatabase mydb,messagedb;
String number;
ArrayList<String> private_num = new ArrayList<String>();
@Override
public void onReceive(Context context, Intent intent) {
//private named database contains numbers those which i wish to hide
mydb=context.openOrCreateDatabase("private", 0,null);
mydb.execSQL("CREATE TABLE IF NOT EXISTS tab1(num INT(13))");
Cursor cur=mydb.rawQuery("select * from tab1", null);
while(cur.moveToNext())
{
number=cur.getString(cur.getColumnIndex("num"));
private_num.add(number);
}
if (intent.getAction().equals("android.provider.Telephony.SMS_RECEIVED")) {
Bundle extras = intent.getExtras();
if (extras != null) {
Object[] pdus = (Object[])extras.get("pdus");
if (pdus.length < 1) return;
StringBuilder sb = new StringBuilder();
String sender = null;
for (int i = 0; i < pdus.length; i++) {
SmsMessage message = SmsMessage.createFromPdu((byte[]) pdus[i]);
if (sender == null) sender = message.getOriginatingAddress();
String text = message.getMessageBody();
if (text != null) sb.append(text);
}
for(int i=0;i<private_num.size();i++)
{
if (sender.equals(private_num.get(i))) {
// create a new database and insert messages
messagedb=context.openOrCreateDatabase("message",0, null);
messagedb.execSQL("CREATE TABLE IF NOT EXISTS tab2(sender INT(13),body varchar)");
mydb.execSQL("INSERT INTO tab2 VALUES('"+sender+"','"+sb+"')");
abortBroadcast();
}
}
}
}
}}
也表现如下
<uses-permission android:name="android.permission.RECEIVE_SMS"/>
<receiver android:name=".SmsFilter">
<intent-filter android:priority="1">
<action android:name="android.provider.Telephony.SMS_RECEIVED" />
</intent-filter>
</receiver>
但是我无法通过这个接收器隐藏我的消息....这是什么原因?......任何人帮助我......我有麻烦......
