android 中的两次振铃状态指示和无空闲/摘机状态指示

Question

当我尝试监控手机状态时，只经过振铃状态。每当来电被应答、拒绝或超时时，永远不会看到其他两种状态，空闲和摘机。并且有一个来电指示两个振铃。这太奇怪了。列出一个电话号码为 02xxxxxxxxx 的来电的运行日志，例如：

---

D/INCOMING：02xxxxxxxxx

D/ori铃声：1

D/州：响铃

D/AudioManager: setStreamVolume(streamType:2, index:7, flags:6)

D/INCOMING：02xxxxxxxxx

D/ori铃声：2

D/州：响铃

D/AudioManager: setStreamVolume(streamType:2, index:7, flags:6)

我添加权限并在 BroadcastReceiver 中注册手机状态更改。

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

和

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

我想知道为什么有两个振铃指示以及如何获得空闲和摘机状态的信息。谢谢。

信息列表代码：

public class PhoneCallHandler extends BroadcastReceiver {
static boolean flag = false;
@Override
public void onReceive(Context context, Intent intent) {
    TelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);

    try {
        Class c = Class.forName(tm.getClass().getName());
        Method m = c.getDeclaredMethod("getITelephony");
        m.setAccessible(true);
        Bundle bundle = intent.getExtras();
        String phoneNumber = bundle.getString("incoming_number");
        Log.d("INCOMING", phoneNumber);

        String state = intent.getExtras().getString(TelephonyManager.EXTRA_STATE);
        //Log.d("ACTION", action);

        AudioManager auManager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
        int oriRingtone = auManager.getRingerMode();
        Log.d("oriRingtone", String.valueOf(oriRingtone));
        Log.d("State", state);

        if (state.equals(TelephonyManager.EXTRA_STATE_RINGING)) {
            switch (phoneNumber) {
                case "02584929790":
                    auManager.setStreamVolume(AudioManager.STREAM_RING, 7, AudioManager.FLAG_ALLOW_RINGER_MODES | AudioManager.FLAG_PLAY_SOUND);
                    break;
            }
        }else{
            auManager.setRingerMode(oriRingtone);
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
}

}

广播接收器

`public class IncommingCallReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {



        String stateStr = intent.getExtras().getString(TelephonyManager.EXTRA_STATE);
        String number = intent.getExtras().getString(TelephonyManager.EXTRA_INCOMING_NUMBER);

        int state = 0;
        if (stateStr.equals(TelephonyManager.EXTRA_STATE_IDLE)) {
            state = TelephonyManager.CALL_STATE_IDLE;


        } else if (stateStr.equals(TelephonyManager.EXTRA_STATE_OFFHOOK)) {
            state = TelephonyManager.CALL_STATE_OFFHOOK;



        } else if (stateStr.equals(TelephonyManager.EXTRA_STATE_RINGING)) {
            state = TelephonyManager.CALL_STATE_RINGING;


        }

    }
}`
