安卓来电和去电监听

在oncreate中注册：

IntentFilter filterss = new IntentFilter();
filterss.addAction("android.intent.action.PHONE_STATE");
phoneReceiver = new PhoneReceiver(new PhoneReceiver.PhoneListener() {
	@Override
	public void status(int type) {//0未知 1挂断 2接通、拨打 3响铃
		//TODO 此处处理自己的业务即可
	}
});
registerReceiver(phoneReceiver, filterss);

在onDestory中取消注册：

if (phoneReceiver != null) {
	unregisterReceiver(phoneReceiver);
	phoneReceiver = null;
}

下面是PhoneReceiver的全部代码：

package tv.buka.roomSdk.receiver;


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.text.TextUtils;
import android.util.Log;
