Retrieve incoming call's phone number in Android
提问by jakob
I would like to retrieve the incoming call's phonenumber and do something with it like the do in http://blog.whitepages.com/2009/02/27/caller-id-by-whitepages-a-new-android-app-that-puts-telemarketers-on-alert/
我想检索来电的电话号码并对其进行处理，就像http://blog.whitepages.com/2009/02/27/caller-id-by-whitepages-a-new-android-app-这让电话推销员警觉/
Could you please help me because I can't find any information about this. Where do i start and how do i get hold of the phonenumber?
你能帮我吗，因为我找不到任何关于这方面的信息。我从哪里开始，如何获得电话号码？
Ok so currently my code looks like below. When I place the call the CustomBroadcastReceiver catches it and the log message is printed out. I can retrieve the telephone number from the bundle. But! I can't get hte CustomPhoneStateListener to work. As you can see I have registered my customPhoneState listener to the receiver but the log message never get's printed out from the CustomPhoneStateListener class. What am I my missing here? Is my thinking correct?
好的，目前我的代码如下所示。当我拨打电话时，CustomBroadcastReceiver 会捕获它并打印出日志消息。我可以从捆绑包中检索电话号码。但！我无法让 CustomPhoneStateListener 工作。如您所见，我已将 customPhoneState 侦听器注册到接收器，但从未从 CustomPhoneStateListener 类中打印出日志消息。我在这里想念什么？我的想法正确吗？
<receiver android:name=".CustomBroadcastReceiver">
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE" />
</intent-filter>
</receiver>
</application>
<uses-sdk android:minSdkVersion="5" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_CONTACTS" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
public class CustomPhoneStateListener extends PhoneStateListener {
private static final String TAG = "CustomPhoneStateListener";
public void onCallStateChange(int state, String incomingNumber){
Log.v(TAG, "WE ARE INSIDE!!!!!!!!!!!");
Log.v(TAG, incomingNumber);
switch(state){
case TelephonyManager.CALL_STATE_RINGING:
Log.d(TAG, "RINGING");
break;
}
}
public class CustomBroadcastReceiver extends BroadcastReceiver {
private static final String TAG = "CustomBroadcastReceiver";
@Override
public void onReceive(Context context, Intent intent) {
Log.v(TAG, "WE ARE INSIDE!!!!!!!!!!!");
TelephonyManager telephony = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
CustomPhoneStateListener customPhoneListener = new CustomPhoneStateListener();
telephony.listen(customPhoneListener, PhoneStateListener.LISTEN_CALL_STATE);
Bundle bundle = intent.getExtras();
String phoneNr= bundle.getString("incoming_number");
Log.v(TAG, "phoneNr: "+phoneNr);
}

Use PhoneStateListener. It has an onCallStateChangedhandler; one of the supplied arguments you'll get is a Stringcontaining the incoming phone number.
使用PhoneStateListener. 它有一个onCallStateChanged处理程序；您将获得的提供的参数之一是String包含传入电话号码的参数。
回答by mikeplate
Your overridden method in CustomPhoneStateListenershould be called onCallStateChanged()(and not onCallStateChange()).
您的重写方法CustomPhoneStateListener应该被调用onCallStateChanged()（而不是onCallStateChange()）。
This would have been spotted by the Java compiler if you would have had the @Overrideannotation, like you have for onReceive().
如果您有@Override注释，Java 编译器就会发现这一点，就像您对onReceive().
