Android 监听电话状态

方法1: 加入权限

<uses-permission android:name="android.permission.READ_PHONE_STATE">uses-permission>

创建类

class MyPhoneStateListener extends PhoneStateListener {

@Override

public void onCallStateChanged(int state, String incomingNumber) { switch(state) {

case TelephonyManager.CALL_STATE_IDLE: //空闲 break;

case TelephonyManager.CALL_STATE_RINGING: //来电 break;

case TelephonyManager.CALL_STATE_OFFHOOK: //摘机（正在通话中） break; } } }

调用方法:

//获取电话通讯服务

TelephonyManager tpm = (TelephonyManager)

this.getSystemService(Context.TELEPHONY_SERVICE); //创建一个监听对象，监听电话状态改变事件

tpm.listen(new MyPhoneStateListener(), PhoneStateListener.LISTEN_CALL_STATE);

方法2:

第一步，写一个Receiver继承自BroadcastReceiver

class PhoneStatReceiver extends BroadcastReceiver {

@Override

public void onReceive(Context context, Intent intent) {

// 如果是拨打电话

if (intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)) { private static String incoming_number = null; private static boolean incomingFlag = false;

private static final String TAG = "PhoneStatReceiver";


}

}

}

incomingFlag = false; String phoneNumber = intent



.getStringExtra(Intent.EXTRA_PHONE_NUMBER);

Log.i(TAG, "call OUT:" + phoneNumber); // 如果是来电

TelephonyManager tm = (TelephonyManager) context



.getSystemService(Service.TELEPHONY_SERVICE);

} else {

switch (tm.getCallState()) {

case TelephonyManager.CALL_STATE_RINGING:

incomingFlag = true;// 标识当前是来电

incoming_number = intent.getStringExtra("incoming_number"); Log.i(TAG, "RINGING :" + incoming_number); break;

if (incomingFlag) { } break;

Log.i(TAG, "incoming ACCEPT :" + incoming_number);

case TelephonyManager.CALL_STATE_OFFHOOK:

case TelephonyManager.CALL_STATE_IDLE: }

if (incomingFlag) { } break;

Log.i(TAG, "incoming IDLE");



第二步：在AndroidManifest.xml，配置写好的Receiver，并拦截相应的BroadCastAction，

另外注意加上相应的权限。



<receiver android:name=".filter.PhoneStatReceiver"> <intent-filter>

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

<uses-permission
