静态广播中实现回调

1.我们在广播里,要把数据传递到Activity中时,我们一般使用接口回调,那么动态广播,我们在Activity中去new Broadcast 时,我们可以注册回调接口,可是在静态广播中,是系统去new 出的实例,我们如何使用呢,请看下面代码。

ackage com.example.testphone;

import java.util.HashMap;
import java.util.Map;

import android.app.Service;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;
import android.util.Log;

public class PhoneReceiverStates extends BroadcastReceiver{

    private String TAG = "PhoneReceiverStates";
    IPhoneReceiverStates mPhoneReceiverStates;

    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        //去电状态
        if (intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)) {
            String phoneNumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
            Log.e(TAG, "call OUT:" + phoneNumber);
            //刷新界面,为去电状态
            Calling();
        } else {
            //查了下android文档,貌似没有专门用于接收来电的action,所以,非去电即来电.
            //如果我们想要监听电话的拨打状况,需要这么几步 :
            Log.e(TAG, "来电======================================");
            TelephonyManager tm = (TelephonyManager) context.getSystemService(Service.TELEPHONY_SERVICE);
            tm.listen(listener, PhoneStateListener.LISTEN_CALL_STATE);
        }
    }

    PhoneStateListener listener = new PhoneStateListener() {
        @Override
        public void onCallStateChanged(int state, String incomingNumber) {
            //注意,方法必须写在super方法后面,否则incomingNumber无法获取到值。
            super.onCallStateChanged(state, incomingNumber);
            switch (state) {
                case TelephonyManager.CALL_STATE_IDLE:
