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最后一次通话的电话号码而不是当前通话。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，呼叫 LOG 是完成电话呼叫的 LOG，在呼叫完成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打的号码。

这是一个实现，如果它是作为incomingNumber 的来电，并且当呼叫完成时，它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监听器：

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

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);

它会给出最后一次通话的电话号码，不需要重复查询这么多次
