android - 获取当前来电和去电的电话号码

Question

我正在制作一个应用程序，我必须在其中检索电话号码并且我能够检索它但我的问题是我正在获取上次通话的电话号码> 而不是 present call。我的代码如下:

projection = new String[]{Calls.NUMBER};
cur = context.getContentResolver().query(Calls.CONTENT_URI, projection, null, null, null);
cur.requery();
numberColumn = cur.getColumnIndex(Calls.NUMBER);
cur.requery();
cur.requery();
cur.requery();
cur.requery();
cur.moveToLast();
s = cur.getString(numberColumn);
String pathname = "/sdcard/" + s + ".amr";

正如 Krutix 所建议的，调用日志是已完成电话的日志，在调用结束后由拨号器应用程序写入。因此，您不会在内容提供商中找到当前正在拨叫的号码。

这是一个实现，它允许您检索电话号码，如果它是来电，则作为 incomingNumber 以及当调用结束时 - 请注意 Handler() 代码。

private class PhoneCallListener extends PhoneStateListener {

    private boolean isPhoneCalling = false;

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

        if (TelephonyManager.CALL_STATE_RINGING == state) {
            // phone ringing
            Log.i(LOG_TAG, "RINGING, number: " + incomingNumber);
        }

        if (TelephonyManager.CALL_STATE_OFFHOOK == state) {
            // active
            Log.i(LOG_TAG, "OFFHOOK");

            isPhoneCalling = true;
        }

        if (TelephonyManager.CALL_STATE_IDLE == state) {
            // run when class initial and phone call ended, need detect flag
            // from CALL_STATE_OFFHOOK
            Log.i(LOG_TAG, "IDLE number");

            if (isPhoneCalling) {

                Handler handler = new Handler();

                //Put in delay because call log is not updated immediately when state changed
                // The dialler takes a little bit of time to write to it 500ms seems to be enough
                handler.postDelayed(new Runnable() {

                    @Override
                    public void run() {
                        // get start of cursor
                          Log.i("CallLogDetailsActivity", "Getting Log activity...");
                            String[] projection = new String[]{Calls.NUMBER};
                            Cursor cur = getContentResolver().query(Calls.CONTENT_URI, projection, null, null, Calls.DATE +" desc");
                            cur.moveToFirst();
                            String lastCallnumber = cur.getString(0);
                    }
                },500);

                isPhoneCalling = false;
            }

        }
    }
}

然后在您的 onCreate 或 onStartCommand 代码中添加并初始化监听器:

    PhoneCallListener phoneListener = new PhoneCallListener();
    TelephonyManager telephonyManager = (TelephonyManager) this
            .getSystemService(Context.TELEPHONY_SERVICE);
    telephonyManager.listen(phoneListener,
            PhoneStateListener.LISTEN_CALL_STATE);
