android - 收到来电时弹出

Question

我想根据来电号码的某些标准创建一个弹出式警报。无论如何，我根据标准创建了一条 toast 消息。但是我坚持创建警报。请帮忙。

//IncomingNumberCheck.java


public class IncomingNumberCheck extends BroadcastReceiver {

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

        if(intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(TelephonyManager.EXTRA_STATE_RINGING)) {
            String incomingNumber = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);

            Toast.makeText(context, networkProvider(incomingNumber), LENGTH_LONG).show();


        } else if(intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(TelephonyManager.EXTRA_STATE_IDLE) || intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(TelephonyManager.EXTRA_STATE_OFFHOOK)) {
            Toast.makeText(context, "Call ended", LENGTH_LONG).show();
        }
    }

    public String networkProvider(String incomingNumber) {
        if(incomingNumber.startsWith("some string") || incomingNumber.startsWith("some string")) {
            return "Particular provider name";
        } else {
            return "Other user";
        }
    }
}

只是一个疯狂的想法...尝试使用服务来监听来电，然后从该服务创建对话。看看这个... Alert dialog from Android service
