Android 我如何知道何时在安卓2.3+；电话开始和停止？

我需要我的应用程序来查明电话何时发生

它应该在另一部电话被呼叫和接听时工作。我只需要我的应用程序得到连接开始和停止的确切时间通知（而不是拨号、铃声等）

这可能吗？

您可以使用广播类来实现这一点，如下所示：

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

    TelephonyManager telephonyManager = (TelephonyManager) context
            .getSystemService(Context.TELEPHONY_SERVICE);
    telephonyManager.listen(new CustomPhoneStateListener(context),
            PhoneStateListener.LISTEN_CALL_STATE);
    }
}

class CustomPhoneStateListener extends PhoneStateListener {

    // private static final String TAG = "PhoneStateChanged";
    Context context; // Context to make Toast if required

    public CustomPhoneStateListener(Context context) {
        super();
        this.context = context;
    }

    @Override
    public void onCallStateChanged(int state, String incomingNumber) {

        super.onCallStateChanged(state, incomingNumber);
        switch (state) {

        case TelephonyManager.CALL_STATE_IDLE:
            //WHEN PHONE WILL BE IDLE       
        break;

        case TelephonyManager.CALL_STATE_OFFHOOK:
            // when Off hook i.e in call
        break;

        case TelephonyManager.CALL_STATE_RINGING:
            // when Ringing
        break;

        default:
        break;
        }
    }
}
