Improve alert function

schotsl

I needed to display alerts in processing android so I got some code from another post and boiled it down to this

import android.app.AlertDialog;

String alertMessage;

void setup() {
  alertMessage = "This is the message";
  createAlert();
}

void createAlert() {
  runOnUiThread(new Runnable() {
    @ Override
      public void run() {
      AlertDialog.Builder alertDialog = new AlertDialog.Builder(getActivity());
      alertDialog.setTitle("Alert");
      alertDialog.setMessage(alertMessage);
      alertDialog.setPositiveButton("OK", null);
      alertDialog.show();
    }
  }
  );
}

Which works great but now to display some text in an alert I have to change the alertMessage and then call the function, there must be a way to turn it into a function that takes in a string, something like this createAlert("This is the message"); but I cant figure out how to do it with the UiThread being inside the function.

Any advice?

Something like what ketai does: http://ketai.org/reference/ui/ketaialertdialog/

You can always explore their source code. On the side, possible relevant code, specially if you are looking for the missing imports:

https://forum.processing.org/two/discussion/3715/i-d-like-to-have-simple-alertdialog-in-my-processing-android-sketch

which are (some of them redundant):

//Import required classes
import android.app.AlertDialog;
import android.app.AlertDialog.Builder;
import android.app.AlertDialog.Builder.*;
import android.app.AlertDialog.*;
import android.content.DialogInterface;

@schotsl===

before trying to answer your question, are you sure that the code you have put can run?

@akenaton @kfrajer Im sorry I forgot to add the import, the only import you need for this code to run is import android.app.AlertDialog;. Then the code will run

kfrajer

Code runs... confirmed!

sorry; as for me line 12 fires: The function "runOnUiThread(Runnable(){})" does not exist s" ;and in order to get rid of it i must add act.run..... (act = Activity getActivity) which seems right as you 're in a fragment.

@shotsl=== not sure to understand your question; yet have a look to the code below which runs well for me:

    String alertMessage = "";
     import android.app.AlertDialog;
    import android.app.AlertDialog.Builder;
    import android.os.Looper;
    import android.app.Activity;
    import android.content.DialogInterface;


    Activity act;

    void setup() {
      size(1024,768);
      orientation(LANDSCAPE);
      act=this.getActivity();
      Looper.prepare();

    };

    void draw(){

    };

    void createAlert() {
      act.runOnUiThread(new Runnable() {
        //@ Override
          public void run() {

          AlertDialog.Builder builder = new AlertDialog.Builder(act);
          AlertDialog alertDialog = builder.create();
          alertDialog.setTitle("Alert");
          alertDialog.setMessage(getMessage());
          alertDialog.setButton("OK", new DialogInterface.OnClickListener() { 
      public void onClick(DialogInterface dialog, int which) {
       println("cliqué=======");

    }}); 
          alertDialog.show();

    }
    });
    };

     void mousePressed(){
        setMessage("encore un");// here you can set the message to some String[x];
        createAlert();
      }

    void setMessage(String mess){

      alertMessage = mess;
    }

    String getMessage(){

      return alertMessage;
    }

@akenaton It's weird that it works for me and @kfrajer but not for you right? Thanks for the improvement anyway :P

My question was If I could turn createAlert into a function that requests a string, createAlert("This is the message"); instead of (what im currently doing):

alertMessage = "This is the message";
createAlert();

Altough now I release I could just create a function with something like this

void displayAlert(String message) {
  alertMessage = message;
  createAlert();
}

This does feel a bit dodgy though..
