如何在android PhoneStateListener中获取断开的电话号码

Question

当我们有来电，拨出和断开呼叫时，我正在使用PhoneStateListener来收听呼叫状态。一切正常。但我的问题是我希望CALL_STATE_IDLE，CALL_STATE_OFFHOOK中的电话号码断开连接。

当我们有来电时，我可以收到来电号码。但是当电话结束时，我无法获得断开连接的电话号码。我正在使用下面的代码。

任何人都可以告诉我如何获取电话号码CALL_STATE_IDLE，CALL_STATE_OFFHOOK。

// Call State Listener
private final class CallStateListener extends PhoneStateListener {
    @Override
    public void onCallStateChanged(int state, String inComingNumber) {
        switch (mCallState) {
            case TelephonyManager.CALL_STATE_IDLE:
                if (state == TelephonyManager.CALL_STATE_OFFHOOK) {
                    // New Outgoing Call
                } else if (state == TelephonyManager.CALL_STATE_RINGING) {
                    System.out.println("New Incoming Call");
                    System.out.println("CallStateListener Incoming Number: " + inComingNumber);
                    // New Incoming Call
                }
                break;

            case TelephonyManager.CALL_STATE_OFFHOOK:
                if (state == TelephonyManager.CALL_STATE_IDLE) {
                    // Call Disconnected
                    System.out.println("CallStateListener Disconnected Number: " + inComingNumber);
                    System.out.println("Call Disconnected");
                } else if (state == TelephonyManager.CALL_STATE_RINGING) {
                    // Another Call Waiting
                }
                break;

            case TelephonyManager.CALL_STATE_RINGING:
                if (state == TelephonyManager.CALL_STATE_OFFHOOK) {
                    System.out.println("Call Received");
                    System.out.println("CallStateListener Received Number: " + inComingNumber);
                    // Call Received
                } else if (state == TelephonyManager.CALL_STATE_IDLE) {
                    System.out.println("CallStateListener Missed Number: " + inComingNumber);
                    // Call Missed
                }else if(state == TelephonyManager.CALL_STATE_RINGING) {
                }
                break;
        }
        mCallState = state;
    }
}

当我使用上面的PhoneStateListener时，我得到的日志为

CallStateListener Incoming Number: 4121312323
CallStateListener Missed Number:
CallStateListener Received Number:
CallStateListener Disconnected Number:

我只能在RINGINE状态下获得来电号码，但我无法获得呼叫接收状态电话号码，呼叫未接来电状态号码和已断开连接的电话号码。请任何帮助指导我。感谢

尝试打开这样的活动：

switch (state) {
case TelephonyManager.CALL_STATE_IDLE:
    Log.v("idle state", "CALL_STATE_IDLE");
    // CALL_STATE_IDLE ( OpenMissedCallScreen )

    if (ring == true && callReceived == false && CheckMissCall.isRunning== false) {
        flag = true;
        if (prefs.getBoolean("main_state", true))
        {
            Intent inter = new Intent(c, MissCall.class);

        }
    }
    break;
case TelephonyManager.CALL_STATE_OFFHOOK:
    // CALL_STATE_OFFHOOK ( OpenReceivedCallScreen )
    callReceived = true;
    break;
case TelephonyManager.CALL_STATE_RINGING:
    ring = true;
    // CALL_STATE_RINGING ( openIncomingCallScreen )
    break;
