Question

通话结束时当前的电话状态是什么。

在android中有三种状态。

TelephonyManager.CALL_STATE_IDLE
TelephonyManager.CALL_STATE_OFFHOOK
TelephonyManager.CALL_STATE_RINGING:

Answer 1

通话结束后，手机状态应为TelephonyManager.CALL_STATE_IDLE

Answer 2

使用PhoneStateListener接收指定电话状态更改的通知。

覆盖onCallStateChanged (int state, String incomingNumber)并检查state参数

if (state == CALL_STATE_IDLE) {  
    //this is current Phone state at the time of call end, handle call end here
}

这三个州表明如下：

CALL_STATE_IDLE - ＆gt;设备呼叫状态：无活动 CALL_STATE_OFFHOOK - ＆GT;设备呼叫状态：摘机。至少存在一个拨号，活动或保持的呼叫，并且没有呼叫振铃或等待 CALL_STATE_RINGING - ＆gt;设备呼叫状态：振铃。一个新的电话到了正在响个不停。在后一种情况下，已经有另一个电话活性

Answer 3

此代码适用于我。希望它能帮到你

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.TelephonyManager;
import android.util.Log;

public class CallStateReceiver extends BroadcastReceiver {

private final String LOG_TAG = "CallStateReceiver";

public static String prevState = TelephonyManager.EXTRA_STATE_IDLE;

@Override
public void onReceive(Context context, Intent intent) {

    Bundle bundle = intent.getExtras();
    if (bundle == null) {
        return;
    }

    String state = bundle.getString(TelephonyManager.EXTRA_STATE);

    if (state.equalsIgnoreCase(TelephonyManager.EXTRA_STATE_IDLE)
            && !prevState.equalsIgnoreCase(TelephonyManager.EXTRA_STATE_IDLE)) {

        Log.i(this.LOG_TAG, "Call ended"));
    }

    prevState = state;
}
}

Answer 4

TelephonyManager.CALL_STATE_IDLE    #When a call end, no matter what, call received by user or not

TelephonyManager.CALL_STATE_OFFHOOK #when user receive a call

TelephonyManager.CALL_STATE_RINGING #when phone ring (incoming call)
