我怎么知道我打电话的人"拿起"他的电话的那一刻？

Answer 1

就 Android 的电话管理器而言，您无法以编程方式检测您的呼叫是否已被应答。

但对于来电来说，使用PhoneStateListener. 当您“拿起”电话时，状态更改为CALL_STATE_OFFHOOK。

TelephonyManager tm = (TelephonyManager)getSystemService(TELEPHONY_SERVICE);
tm.listen(mPhoneListener, PhoneStateListener.LISTEN_CALL_STATE);

private PhoneStateListener mPhoneListener = new PhoneStateListener() {
    public void onCallStateChanged(int state, String incomingNumber) {
        try {
            switch (state) {
            case TelephonyManager.CALL_STATE_RINGING:
                // do something...
                break;

            case TelephonyManager.CALL_STATE_OFFHOOK:
                // you picked up the phone
                break;

            case TelephonyManager.CALL_STATE_IDLE:
                // do something...
                break;
            default:
                Log.d(TAG, "Unknown phone state=" + state);
            }
        } catch (RemoteException e) {}
    } 
};
