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呼叫的电话号码而不是当前呼叫。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";

Answer 1

正如 Krutix 所建议的那样，呼叫日志是已完成电话呼叫的日志，在呼叫完成后由拨号器应用程序写入。因此，您将找不到当前正在内容提供商中拨打的号码。

这是一个实现，如果它是传入

电话作为传入号码，并且当呼叫完成时，它将允许您检索电话号码 - 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 onCreate 或 onStartCommand 代码中添加并初始化侦听器：

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

Answer 2

请修改您的查询

 cur = context.getContentResolver().query(Calls.CONTENT_URI,
                        projection, null, null, Calls.DATE +" desc");
  cur.moveToFirst();
  s = cur.getString(numberColumn);

它会给出最后一个电话的电话号码，没有必要重新查询这么多次
