我可以在后台的广播接收器中显示自定义视图吗？

Question

I have a broadcast receiver that works in the background of my app and I want to show a custom popup view on the phone every time it triggers. (every time the onReceive method is called)

can I show a custom view of my own (just some pic with some text in it) on top of the phone from within the BroadcastReciever? (very similar to what the messenger is doing when u get a message in facebook)

do you have a code example of how I can achieve that?

here is my receiver

public class PhoneStateReciver extends BroadcastReceiver {


    @Override
    public void onReceive(Context context, Intent intent) {

        String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
        String incomingNumber = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);

        if(state.equals(TelephonyManager.EXTRA_STATE_RINGING)){
            //Toast.makeText(context,"Ringing State Number is -"+incomingNumber,Toast.LENGTH_SHORT).show();
            getContactList(context, incomingNumber);
        }
        if ((state.equals(TelephonyManager.EXTRA_STATE_OFFHOOK))){
            Toast.makeText(context,"Received State",Toast.LENGTH_SHORT).show();
        }
        if (state.equals(TelephonyManager.EXTRA_STATE_IDLE)){
            Toast.makeText(context,"Idle State",Toast.LENGTH_SHORT).show();
        }


    }
}
