Question

我正试图在Android上进行电话通话时以编程方式设置电话拨号器的数量，但我暂时找不到解决方案。

我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，我可以使用ACTION_DIAL而不是ACTION_CALL来设置电话拨号器，并且我可以设置电话拨号器，但是在电话呼叫时我无法设置电话拨号器。

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。提前谢谢。

你在两个非常相似的活动之间混淆，但仍然非常不同：

Phone的拨号程序 - 允许用户拨打某个电话号码
InCallUi的拨号程序 - 允许用户在调用导航菜单时发送键控。

第一个设置为接收ACTION_CALL / ACTION_DIAL意图，第二个设置没有设置广播意图，因此您无法操纵它。

如何在电话中以编程方式在电话拨号器屏幕中设置号码？
