Question

Sorry for my bad english. I’ve a table row and i’ve set the first view with record’s code. I’ve set this view with 0px height and 0px width. But it takes me half screen! Why? Where is the mistake?

This is the code:

        try{

        txtId= new TextView(this);
        imgCategory= new ImageView(this);
        txtDescrizione= new TextView(this);
        txtDataFine= new TextView(this);
        imgPriorita= new ImageView(this);

        txtId.setText(id);
        txtId.setWidth(0);
        txtId.setHeight(0);
        txtId.setTextColor(getResources().getColor(R.color.white));
        txtId.setTextSize(1);


        if(priorita.equalsIgnoreCase("3")){
            imgPriorita.setImageResource(R.drawable.todo_priority_3);}
        else if(priorita.equalsIgnoreCase("2")){
            imgPriorita.setImageResource(R.drawable.todo_priority_2);}
        else if(priorita.equalsIgnoreCase("1")){
            imgPriorita.setImageResource(R.drawable.todo_priority_1);}

        imgPriorita.setPadding(0, 0, 0, 0);
        imgPriorita.setMaxWidth(widthDisplay/10);
        imgPriorita.setMaxHeight(40);
        imgPriorita.setScaleType(ScaleType.CENTER_INSIDE);


        txtDescrizione.setPadding(0, 0, 0, 0);
        //txtDescrizione.setText(Html.fromHtml("<i>"+descrizione+"</i>"));
        txtDescrizione.setText(descrizione);
        txtDescrizione.setTextColor(getResources().getColor(R.color.black));
        txtDescrizione.setWidth(widthDisplay/5);
        txtDescrizione.setHeight(40);
        txtDescrizione.setTextSize(12);
        //setto la descrizione su una sola riga e con true fino a quando ci stanno le lettere
        txtDescrizione.setSingleLine(true);
        txtDescrizione.setLines(1);


        txtDataFine.setPadding(0, 0, 0, 0);
        txtDataFine.setText(data.getDateTimeTodo(dataFine));
        txtDataFine.setWidth(widthDisplay/5);
        txtDataFine.setHeight(40);
        txtDataFine.setTextColor(getResources().getColor(R.color.black));
        txtDataFine.setGravity(Gravity.CENTER);
        txtDataFine.setTextSize(12);

        if(category.equalsIgnoreCase("2")){
            imgCategory.setImageResource(R.drawable.todo_category_2);}
        else if(category.equalsIgnoreCase("1")){
            imgCategory.setImageResource(R.drawable.todo_category_1);}
        else if(category.equalsIgnoreCase("3")){
            imgCategory.setImageResource(R.drawable.todo_category_3);}
        else if(category.equalsIgnoreCase("5")){
            imgCategory.setImageResource(R.drawable.todo_category_5);}
        else if(category.equalsIgnoreCase("4")){
            imgCategory.setImageResource(R.drawable.todo_category_4);}
        else if(category.equalsIgnoreCase("6")){
            imgCategory.setImageResource(R.drawable.todo_category_6);}



        imgCategory.setPadding(0,0,0,0);
        imgCategory.setMaxWidth(widthDisplay/5);
        imgCategory.setMaxHeight(40);
        imgCategory.setScaleType(ScaleType.CENTER_INSIDE);

        rowTodo[counterBackground]= new TableRow(this); 
        if((counterBackground%2)==0){
            rowTodo[counterBackground].setBackgroundColor(getResources().getColor(R.color.greyListCp));}
        else{
            rowTodo[counterBackground].setBackgroundColor(getResources().getColor(R.color.white));}

        rowTodo[counterBackground].setMinimumHeight(heightRowTodo);
        idRow_gl=Integer.parseInt(id);
        rowTodo[counterBackground].setId(idRow_gl);

        rowTodo[counterBackground].setOnClickListener(new OnClickListener() {
            public void onClick(View view_cliccata) {
                    onclickRow(view_cliccata);
            }   
        });


        imgAnagraficaTodo[counterBackground]=new ImageView(this);

        if(id_anagTodo.equals("")){}
        else{   
            imgAnagraficaTodo[counterBackground].setImageResource(R.drawable.toanag);
            imgAnagraficaTodo[counterBackground].setPadding(20, 3, 0, 0);
            imgAnagraficaTodo[counterBackground].setMinimumWidth(widthDisplay/5);
            imgAnagraficaTodo[counterBackground].setMaxHeight(40);
            imgAnagraficaTodo[counterBackground].setId(idRow_gl);
            imgAnagraficaTodo[counterBackground].setScaleType(ScaleType.CENTER_INSIDE);

            imgAnagraficaTodo[counterBackground].setOnClickListener(new OnClickListener() {
                public void onClick(View view_cliccata) {
                        Data.myHashMapVar.put("ID_TODO", view_cliccata.getId());
                        onclickImgAnagraficaTodo(view_cliccata,id_anagTodo);
                }   
            });
            arrList_AnagTodo.add(id_anagTodo);
        }

        rowTodo[counterBackground].addView(txtId);
        rowTodo[counterBackground].addView(imgPriorita);
        rowTodo[counterBackground].addView(txtDescrizione);
        rowTodo[counterBackground].addView(txtDataFine);
        rowTodo[counterBackground].addView(imgCategory);
        rowTodo[counterBackground].addView(imgAnagraficaTodo[counterBackground]);


        List_TodoList.addView(rowTodo[counterBackground]);

        } catch (Exception e) {
            e.printStackTrace();
        }

    }

And heightDisplay and widthDisplay are set in this way:

display=getWindowManager().getDefaultDisplay();
             heightDisplay=display.getHeight();
             widthDisplay=display.getWidth();

Thanks in advance!
