实现android手机来电拦截系统页面弹出自定义页面特效

如何实现android手机来电拦截系统页面弹出自定义页面特效，

首先：
我们需要注册一个监听来电的广播PhoneStateReceiver 类：
其次：
在onReceive里面我们获取android 电话状态的监听(来电和去电）
实现手机电话状态的监听，主要依靠两个类：TelephoneManger和PhoneStateListener。
TelephonseManger提供了取得手机基本服务的信息的一种方式。
因此应用程序可以使用TelephonyManager来探测手机基本服务的情况。
应用程序可以注册listener来监听电话状态的改变。我们不能对TelephonyManager进行实例化，
只能通过获取服务的形式：Context.getSystemService(Context.TELEPHONY_SERVICE);
特别注意来去电需要添加权限：

我在项目中主要监听
Intent.ACTION_NEW_OUTGOING_CALL //去电广播意图

Intent.ACTION_NEW_OUTGOING_CALL //拨打电话广播

android.intent.action.PHONE_STATE //电话状态改变是会发送action

通过：numbers = intent.getStringExtra("incoming_number");获取number

最后：我主要的实现方法
CallTask(states,numbers);//去电处理， 启动ExhaleAnimation 类，在广播页面不宜处理很耗时的
操作，因为广播的生命周期很短，挂电话的时候可以监听挂电动作，然后把自己自定义的页面销毁。


public class PhoneStateReceiver extends BroadcastReceiver {
public Context mContext;
private AudioManager mAudioManager;
int ringerMode;
boolean isSystemRingtone;
public String numbers;
String outgoing_call;
boolean outcall_value = false;
@Override

mContext = context;
mAudioManager = (AudioManager) context

ringerMode = mAudioManager.getRingerMode();
TelephonyManager tm = (TelephonyManager) context
.getSystemService(Service.TELEPHONY_SERVICE);
int states = tm.getCallState();
String action = intent.getAction();
isSystemRingtone = getRingMode();
setMute(true);
numbers = intent.getStringExtra("incoming_number");

if (action.equals("android.intent.action.PHONE_STATE")) {

CallTask(states,numbers);
}else if(intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)){
outcall_value = true;
outgoing_call = this.getResultData();
ExhaledTask(outgoing_call);
}
