如何在电话通话中以编程方式在电话拨号器屏幕中设置号码？

Question

我正在尝试在 Android 上打电话时以编程方式设置电话拨号器的号码，但我暂时找不到解决方案。

我正在使用此代码设置电话拨号器并在用户拨打给定号码时拨打电话：

Intent intent = new Intent(Intent.ACTION_CALL);
    intent.setData(Uri.parse("tel:04445556677"));
    startActivity(intent);

另外，我可以在空闲时使用 ACTION_DIAL 而不是 ACTION_CALL 来设置电话拨号器，我可以用它设置电话拨号器，但我不能在通话时设置电话拨号器。

此外，这是我的呼叫接收器类：

public class CallReceiver extends BroadcastReceiver {

private static int lastState = TelephonyManager.CALL_STATE_IDLE;
private static Date callStartTime;
private static boolean isIncoming;
private static String savedNumber;



@Override
public void onReceive(Context context, Intent intent) {
    //Log.w("intent " , intent.getAction().toString());


    if (intent.getAction().equals("android.intent.action.NEW_OUTGOING_CALL")) {
        savedNumber = intent.getExtras().getString("android.intent.extra.PHONE_NUMBER");//buda çekiyor sanırsam

    } else {
        String stateStr = intent.getExtras().getString(TelephonyManager.EXTRA_STATE);
        String number = intent.getExtras().getString(TelephonyManager.EXTRA_INCOMING_NUMBER);//tel numarasını çekiyor
        int state = 0;
        if (stateStr.equals(TelephonyManager.EXTRA_STATE_IDLE)) {
            state = TelephonyManager.CALL_STATE_IDLE;
        } else if (stateStr.equals(TelephonyManager.EXTRA_STATE_OFFHOOK)) {
            state = TelephonyManager.CALL_STATE_OFFHOOK;

        } else if (stateStr.equals(TelephonyManager.EXTRA_STATE_RINGING)) {
            state = TelephonyManager.CALL_STATE_RINGING;
        }

        onCallStateChanged(context, state, number);
    }
}



public void onCallStateChanged(Context context, int state, String number) {
    if (lastState == state) {
        //No change, debounce extras
        return;
    }
    switch (state) {
        case TelephonyManager.CALL_STATE_RINGING:
            isIncoming = true;
            callStartTime = new Date();
            savedNumber = number;

            Toast.makeText(context, "Incoming Call Ringing", Toast.LENGTH_SHORT).show();


            break;
        case TelephonyManager.CALL_STATE_OFFHOOK:
            //Transition of ringing->offhook are pickups of incoming calls.  Nothing done on them
            if (lastState != TelephonyManager.CALL_STATE_RINGING) {
                isIncoming = false;
                callStartTime = new Date();
                Toast.makeText(context, "Outgoing Call Started", Toast.LENGTH_SHORT).show();

            }

            break;
        case TelephonyManager.CALL_STATE_IDLE:
            //Went to idle-  this is the end of a call.  What type depends on previous state(s)
            if (lastState == TelephonyManager.CALL_STATE_RINGING) {
                //Ring but no pickup-  a miss
                Toast.makeText(context, "Ringing but no pickup" + savedNumber + " Call time " + callStartTime + " Date " + new Date(), Toast.LENGTH_SHORT).show();
            } else if (isIncoming) {

                Toast.makeText(context, "Incoming " + savedNumber + " Call time " + callStartTime, Toast.LENGTH_SHORT).show();
            } else {

                Toast.makeText(context, "outgoing " + savedNumber + " Call time " + callStartTime + " Date " + new Date(), Toast.LENGTH_SHORT).show();

            }

            break;
    }
    lastState = state;
}

}

我希望有人可以帮助我。提前致谢。

您在两个非常相似的活动之间感到困惑，但仍然非常不同：

1. Phone 的拨号器 - 允许用户拨打某个电话号码
2. InCallUi 的拨号器 - 允许用户在通话期间发送按键音以导航菜单。

第一个被设置为接收ACTION_CALL/ACTION_DIAL意图，第二个没有设置广播意图，所以你不能操纵它。
