Question

Me Doing “edu.sju.BlackJack” Is not causing updates that are later called to occur.
I reference the layout correctly and the calls that are supposed to update it are correct, so what do I put in for the package name?

I should add that my package name according to the manifest is the above.
This is the code I have now which currently doesn’t update the screen (or i’m guessing change the value correctly).

RemoteViews name = new RemoteViews(“edu.sju.BlackJack”, R.layout.play_screen);

If that’s not it.. would it then be this code?

name.setTextViewText(R.id.Dealer_Total, “0”);

Dealer_Total is the id for the TextView that I want to change.. however again the Change is not occurring.

Thanks in advance for any and all assistance.

Here is the whole of my code that i’m talking about, first Playscreen.java

package edu.sju.BlackJack;
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.widget.ImageView;
import android.widget.RemoteViews;
import android.widget.TextView;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import java.util.*;


public class PlayScreen extends Activity implements OnClickListener {
    /** Called when the activity is first created. */
    GameEngine Engine = new GameEngine();
     @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.play_screen);
        TextView TextDealer =  (TextView)findViewById(R.id.Dealer_Total); 
        Engine.setView(TextDealer);
        //Set up click listeners for all the buttons
        View hitButton = findViewById(R.id.hit_button);
        hitButton.setOnClickListener(this);
        View standButton = findViewById(R.id.stand_button);
        standButton.setOnClickListener(this);
        //new preplay button (ML 10/24/10)
        View prePlayButton = findViewById(R.id.prePlay_button);
        prePlayButton.setOnClickListener(this);
        Thread thread = new Thread(Engine);
        thread.start();


    }   

    public void onClick(View v) {
        switch (v.getId()) {

            case R.id.prePlay_button:
                v.setVisibility(View.GONE);
                System.out.println("Working?");
                Engine.setGameStart(1);
                break;
            case R.id.hit_button:
                Engine.gameHit(1);
                break;
            case R.id.stand_button:
                Engine.gameStand(1);
                break;
        }

            // More buttons go here (if any) ...    
        }
}

Now here’s the GameEngine Thread
Not the Whole of it, just enough so you get the idea

Whatever your problem is, I don’t think it is what you think it is. If your layout is appearing in the app widget, then the package name is being handled properly. If the update (your setTextViewText() call) is not having an effect, then either R.layout.play_screen does not have R.id.Dealer_Total or you are not sending over a RemoteViews that contains the setTextViewText() instructions.
