Android有来电时如何获取电话号码？

Answer 1

制作一个广播接收器说ServiceReceiver在Manifest中分配它的 Action 。

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

添加一个 PhoneStateListener 到您的 TelephonyManager，PhoneStateListener 使用传入号码参数覆盖 onCallStateChanged()。就是这样。

ServiceReceiver.Java

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);
    }
}
