Android如何隐藏表格布局

Question

在我的android应用程序中进行爱兼容性测试..首先在同一页中输入男孩的详细信息，然后再输入女孩的详细信息。 单独的保存按钮，用于保存男孩和女孩的详细信息，这些数据保存在单独的数据库中。 还有一个针对男孩和女孩的召回按钮。 按下此调用按钮后，数据库将打开，该用户可以从中选择要检查的名称。 当他按下时，必须将相应的数据输入到相应的编辑文本中。 就我而言，我不知道如何关闭此表行。 这意味着数据库已打开。然后只有数据将转到相应的edittext框。

我在下面给出我的代码

主要活动

btn4.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub

            Cursor c = dbb.rawQuery("SELECT * from Data3", null);
            int count = c.getCount();
            c.moveToFirst();

            tableLayout.setVerticalScrollBarEnabled(true);

            textView1.setTextColor(Color.BLACK);
            textView1.setTypeface(null, Typeface.BOLD);
            textView1.setPadding(20, 20, 20, 20);

            tableLayout.addView(tableRow);


            for(Integer j=0; j<count; j++)

            }

            c.close();
            setContentView(tableLayout);
              dbb.close();

        }

Answer 1

声明表布局的侧面按钮单击并使其消失/不可见

 tablelayout.setVisibility(View.INVISIBLE);//white space will be available

要么

 tablelayout.setVisibility(View.GONE);//No white space
