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,我必须检索电话号码,我能够检索它,但我的问题是我得到的是最后一次通话的电话号码,而不是现在的电话.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";

根据Krutix的建议,呼叫LOG是完成电话呼叫的日志,在呼叫结束后由拨号器应用程序写入.因此,您将无法找到当前在内容提供商中拨打的号码.

这是一个实现,它允许您检索电话号码,如果它是来电呼叫作为来电号码,并且当呼叫结束时 - 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);
