对不起，我的英语不好。我有一个表格行，我已经用记录的代码设置了第一个视图。我已经将此视图设置为 0px 高度和 0px 宽度。但它需要我半屏！为什么？错误在哪里？

这是代码：

        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();
        }

    }

而heightDisplay和widthDisplay是这样设置的：

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

提前致谢！

您真的应该真正考虑使用布局 xml 而不是屏幕设计代码，请查看本教程以获取更多信息：http: //developer.android.com/guide/topics/ui/declaring-layout.html

关于您的问题，我建议使用可见性而不是更改宽度/高度：

txtId.setVisibility(View.GONE);

如果你不想它消失。为什么不直接使用

txtId.setVisibility(View.GONE);

?
