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
