[英]How to get contact name when receiving SMS
我有以下代碼來接收短信,我正在嘗試獲取聯系人姓名。
package com.example.smsTest;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.database.Cursor;
import android.net.Uri;
import android.os.Bundle;
import android.provider.ContactsContract;
import android.provider.ContactsContract.PhoneLookup;
import android.telephony.SmsMessage;
import android.widget.Toast;
public class SmsReceiver extends BroadcastReceiver {
private SQLiteAdapter mySQLiteAdapter;
@Override
public void onReceive(Context context, Intent intent) {
mySQLiteAdapter = new SQLiteAdapter(context);
mySQLiteAdapter.openToRead();
Message message = null;
Bundle extras = intent.getExtras();
if (extras == null)
return;
Object[] pdus = (Object[]) extras.get("pdus");
for (int i = 0; i < pdus.length; i++) {
SmsMessage SMessage = SmsMessage.createFromPdu((byte[]) pdus[i]);
String sender = SMessage.getOriginatingAddress();
String body = SMessage.getMessageBody().toString();
message = mySQLiteAdapter.createMessage(sender, body);
// A custom Intent that will used as another Broadcast
Intent in = new Intent("SmsMessage.intent.MAIN").putExtra(
"get_msg", sender + ":" + body);
// To display a Toast whenever there is an SMS.
Toast.makeText(context, body, Toast.LENGTH_LONG).show();
Uri personUri = Uri.withAppendedPath( ContactsContract.PhoneLookup.CONTENT_FILTER_URI, SMessage.getOriginatingAddress());
Cursor cur = context.getContentResolver().query(personUri, new String[] { PhoneLookup.DISPLAY_NAME }, null, null, null );
if( cur.moveToFirst() ) {
int nameIndex = cur.getColumnIndex(PhoneLookup.DISPLAY_NAME);
String PersonName = cur.getString(nameIndex);
Toast.makeText(context, PersonName, Toast.LENGTH_LONG).show();
}
cur.close();
// You can place your check conditions here(on the SMS or the
// sender)
// and then send another broadcast
context.sendBroadcast(in);
// This is used to abort the broadcast and can be used to silently
// process incoming message and prevent it from further being
// broadcasted. Avoid this, as this is not the way to program an
// app.
this.abortBroadcast();
}
}
}
這是我添加的代碼導致我的應用崩潰:
Uri personUri = Uri.withAppendedPath( ContactsContract.PhoneLookup.CONTENT_FILTER_URI, SMessage.getOriginatingAddress());
Cursor cur = context.getContentResolver().query(personUri, new String[] { PhoneLookup.DISPLAY_NAME }, null, null, null );
if( cur.moveToFirst() ) {
int nameIndex = cur.getColumnIndex(PhoneLookup.DISPLAY_NAME);
String PersonName = cur.getString(nameIndex);
Toast.makeText(context, PersonName, Toast.LENGTH_LONG).show();
}
cur.close();
我剛從這個鏈接的答案中修改了代碼。
現在,應用程序在收到短信時崩潰了。
試試這個代碼
在廣播接收器中
public class SMSReceiver extends BroadcastReceiver{
String str = "";
String no = "";
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
Bundle bundle = intent.getExtras();
SmsMessage[] msgs = null;
if (bundle != null)
{
//---retrieve the SMS message 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]);
str += msgs[i].getMessageBody().toString();
str += "\n";
no = msgs[i].getOriginatingAddress();
//Resolving the contact name from the contacts.
Uri lookupUri = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI, Uri.encode(no));
Cursor c = context.getContentResolver().query(lookupUri, new String[]{ContactsContract.Data.DISPLAY_NAME},null,null,null);
try {
c.moveToFirst();
String displayName = c.getString(0);
String ContactName = displayName;
Toast.makeText(context, ContactName, Toast.LENGTH_LONG).show();
} catch (Exception e) {
// TODO: handle exception
}finally{
c.close();
}
}
}
}
}
您必須使用intentfilter在清單中注冊此廣播接收器
<receiver android:name="SMSReceiver">
<intent-filter>
<action android:name= "android.provider.Telephony.SMS_RECEIVED" />
</intent-filter>
</receiver>
此外,您還必須添加用戶權限
<uses-permission android:name="android.permission.SEND_SMS"/>
<uses-permission android:name="android.permission.RECEIVE_SMS"/>
<uses-permission android:name="android.permission.READ_CONTACTS"/>
