无论是拨打电话还是来电，系统广播都会发送相应的消息的，我们可以监听广播来获取手机电话状态。
首先在manifest文件中配置自己的BroadcastReceiver，和声明权限。
<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 android:name="android.permission.READ_PHONE_STATE"></uses-permission>
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS"></uses-permission>
在自己的BroadcastReceiver中做相应的处理。
import android.app.Service;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.telephony.TelephonyManager;
import android.util.Log;
public class PhoneStatReceiver extends BroadcastReceiver {
private static final String TAG = "PhoneStatReceiver";
private static boolean incomingFlag = false;
private static String incoming_number = null;
@Override
public void onReceive(Context context, Intent intent) {
// 如果是拨打电话
if (intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)) {
incomingFlag = false;
String phoneNumber = intent
.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
Log.i(TAG, "call OUT:" + phoneNumber);
}
else {
// 如果是来电
TelephonyManager tm = (TelephonyManager) context
.getSystemService(Service.TELEPHONY_SERVICE);
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;
case TelephonyManager.CALL_STATE_OFFHOOK: // 存在至少有一个呼叫拨号，活跃，或
// //保留，并没有来电振铃或等待
if (incomingFlag) {
Log.i(TAG, "incoming ACCEPT :" + incoming_number);
}
break;
case TelephonyManager.CALL_STATE_IDLE: // 闲置状态
if (incomingFlag) {
Log.i(TAG, "incoming IDLE");
}
break;
}
}
}
}
