如何获取来电号码？ [Android]

Question

我正在尝试使用 Android 获取来电号码，但它 return 为空。

我在清单中添加用户权限：

<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
<receiver android:name=".ServiceReceiver" >
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE" />
</intent-filter>

并使用这个 class:

public class ServiceReceiver extends BroadcastReceiver {

@Override
public void onReceive(final Context context, Intent intent) {
TelephonyManager telephony = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
telephony.listen(new PhoneStateListener(){
    @Override
    public void onCallStateChanged(int state, String incomingNumber) {
        super.onCallStateChanged(state, incomingNumber);
        System.out.println("incomingNumber : "+incomingNumber);
    }
 },PhoneStateListener.LISTEN_CALL_STATE);
}

但是不管用，知道吗？

Answer 1

请注意，如果你想获得incomingNumber，你需要权限READ_CALL_LOG，你可以查看文档here

String: call phone number. If application does not have READ_CALL_LOG permission or carrier privileges (see TelephonyManager#hasCarrierPrivileges), an empty string will be passed as an argument.
