Checking all Invisible buttons rows and columns Android

Question

Here is the situation, Im clicking my buttons then make it invisble Onclick. Question is: How can I check if all of my buttons are invisible(no one left) in columns and rows. Then execute another command. Here is some of my screenshot buttons that current visible.

My Code:

 private void loadCards(){
            try{
                givingcards.start();

                int size = ROW_COUNT*COL_COUNT;

                Log.i("loadCards()","size=" + size);

                ArrayList<Integer> list = new ArrayList<Integer>();

                for(int i=0;i<size;i++){
                    list.add(new Integer(i));
                }


                Random r = new Random();

                for(int i=size-1;i>=0;i--){
                    int t=0;

                    if(i>0){
                        t = r.nextInt(i);
                    }

                    t=list.remove(t).intValue();
                    cards[i%COL_COUNT][i/COL_COUNT]=t%(size/2);

                    Log.i("loadCards()", "card["+(i%COL_COUNT)+
                            "]["+(i/COL_COUNT)+"]=" + cards[i%COL_COUNT][i/COL_COUNT]);
                }
            }
            catch (Exception e) {
                Log.e("loadCards()", e+"");
            }

        }

        private TableRow createRow(int y){
             TableRow row = new TableRow(context);
             row.setHorizontalGravity(Gravity.CENTER);

             for (int x = 0; x < COL_COUNT; x++) {
                     row.addView(createImageButton(x,y));
             }
             return row;
        }

        private View createImageButton(int x, int y){
            Button button = new Button(context);
            button.setBackgroundDrawable(backImage);
            button.setId(100*x+y);
            button.setOnClickListener(buttonListener);
            return button;
        }

Assuming you have your `DataModel` which you pass to the adapter, you should have a field in that `DataModel` which tells you if it's `flipped` or not, you can then check if all of them are flipped based on that. — Ionut J. Bejan, Jun 18 '18 at 08:11
Ok, thanks for your response. But can you show me an example code with that? btw. I generated that buttons manually in my code. — Kenth Joshua Espina, Jun 18 '18 at 08:15
I could, if you post your `DataModel` class which you pass to the adapter. Maybe your adapter also and when you switch `visibility` of your view — Ionut J. Bejan, Jun 18 '18 at 08:19
What kind of layout it is? it is GridView, RecyclerView or a simple layout - RelativeLayout, LinearLayout? — NehaK, Jun 18 '18 at 08:33

there is a simple solution you can apply, that is using a variable as counter, it will update whenever onClick() be called

   int counter = 0;

    public void onClick(View view) {
      // visible button ..
      counter++;
      checkButtonsStatus();
    }

    public checkButtonsStatus() {
    if (counter == (4*4)) {
      // all buttons is visible
    }
    }
}

hope this helps

Try this code :

Add method below in createImageButton(); :

button.setTag(100*x+y);

in your buttonListener put add following code :

public void checkCards(){
                if(cards[secondCard.x][secondCard.y] == cards[firstCard.x][firstCard.y]){
                    successpair.start();
                    firstCard.button.setVisibility(View.INVISIBLE);
                    secondCard.button.setVisibility(View.INVISIBLE);
                }
                else {
                    wrongpair.start();
                    secondCard.button.setBackgroundDrawable(backImage);
                    firstCard.button.setBackgroundDrawable(backImage);
                }

                firstCard=null;
                secondCard=null;


                // check here


                boolean isAnyViewVisible = false;

                for (int y = 0; y < ROW_COUNT; y++) {
                    for (int x = 0; x < COL_COUNT; x++) {
                        View view = findViewWithTag(100 * x + y);

                        if (view!=null && view.getVisibility() == VISIBLE) {
                            isAnyViewVisible = true;
                            break;
                        }
                    }
                    if (isAnyViewVisible) {
                        break;
                    }
                }

                if (!isAnyViewVisible) {
                    // write your code here, which you want to execute when all views are invisible

                }


            }

Change this method too to this one :

    // check here
    private void turnCard(Button button,int x, int y) {
        button.setBackgroundDrawable(images.get(cards[x][y]));

        if(firstCard==null){
            firstCard = new Card(button,x,y);

//setTag here firstCard.button.setTag(100*x+y); } else{

            if(firstCard.x == x && firstCard.y == y){
                return; //the user pressed the same card
            }

            secondCard = new Card(button,x,y);

//setTag here

            secondCard.button.setTag(100*x+y);

            turns++;
            ((TextView)findViewById(R.id.tv1)).setText("Tries: "+turns);


            TimerTask tt = new TimerTask() {

                @Override
                public void run() {
                    try{
                        synchronized (lock) {
                            handler.sendEmptyMessage(0);
                        }
                    }
                    catch (Exception e) {
                        Log.e("E1", e.getMessage());
                    }
                }
            };

            Timer t = new Timer(false);
            t.schedule(tt, 1300);
        }


    }

what crash is it? – NehaK Jun 18 '18 at 12:12
I have changed code, try this one – NehaK Jun 18 '18 at 12:17
btw. I had already Onclick listener with this execution, where I can put your code in order to work? Just check. – Kenth Joshua Espina Jun 18 '18 at 12:25
below turnCard(); at last line – NehaK Jun 18 '18 at 12:31
put the code written below // put this at end of method – NehaK Jun 18 '18 at 12:32
this code is written in fragment or Activity? – NehaK Jun 18 '18 at 12:32
Written in MainActivity Sir. – Kenth Joshua Espina Jun 18 '18 at 12:34
I had error in getview: The method getView() is undefined for the type MainActivity.ButtonListener – Kenth Joshua Espina Jun 18 '18 at 12:39
Here is my full source code of MainActivity.java: http://pasted.co/91d42384 maybe you could check it. – Kenth Joshua Espina Jun 18 '18 at 12:50
I edited code using your code, change onCLick method like this – NehaK Jun 18 '18 at 13:09

Hello, I updated code, you should put that method at last of checkCards() – NehaK Jun 19 '18 at 12:49
Hello Sir, Thank you for reply, Unfortunately after I click two buttons it executes command even though they are not invisible. Maybe I can share to you my full project to see. How can I send it to you? – Kenth Joshua Espina Jun 19 '18 at 14:33
just share the main_interface.xml code – NehaK Jun 20 '18 at 07:01
