public class TableViewActivity extends AppCompatActivity {

    TableLayout tableLayout;
    TableRow tableRow;
    TextView textView1, textView2;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_table_view);
        tableLayout = (TableLayout) findViewById(R.id.tableLayout);
        tableRow = (TableRow) findViewById(R.id.tableRow2);
        textView1 = (TextView) findViewById(R.id.TextViewRowTwo1);
        textView2 = (TextView) findViewById(R.id.TextViewRowTwo2);

        List<Student> students = new ArrayList<>();
        students.add(new Student(1, "Mahmud"));
        students.add(new Student(2, "Saiful"));
        students.add(new Student(3, "Monir"));
        students.add(new Student(4, "Milton"));


        for (int j = 0; j< students.size(); j++) {

            textView1.setText(students.get(j).getId()+"");
            textView2.setText(students.get(j).getName());

            // TEXTVIEW
            if(textView1.getParent()!=null)
                ((ViewGroup)textView1.getParent()).removeView(textView1); // <- fix
            tableRow.addView(textView1);

            if(textView2.getParent()!=null)
                ((ViewGroup)textView2.getParent()).removeView(textView2); // <- fix
            tableRow.addView(textView2);

            if(tableRow.getParent()!=null)
                ((ViewGroup)tableRow.getParent()).removeView(tableRow); // <- fix
            tableLayout.addView(tableRow);

        }

        setContentView(tableLayout);

    }

}

您需要动态创建TableRow，每当您将值放入tablerow时，您需要将该tablerow添加到tablelayut。

for (int j = 0; j< students.size(); j++) {
    TableRow tableRow = new TableRow(this);
    textView1.setText(students.get(j).getId()+"");
    textView2.setText(students.get(j).getName());

    // TEXTVIEW
    if(textView1.getParent()!=null)
         ((ViewGroup)textView1.getParent()).removeView(textView1); // <- fix
         tableRow.addView(textView1);
         tableLayout.addView(tableRow);


     if(textView2.getParent()!=null)
         ((ViewGroup)textView2.getParent()).removeView(textView2); // <- fix
         tableRow.addView(textView2);
         tableLayout.addView(tableRow);

    if(tableRow.getParent()!=null)
        ((ViewGroup)tableRow.getParent()).removeView(tableRow); // <- fix
        tableLayout.addView(tableRow);

    }

希望这对你有用。

我认为在你的情况下使用ListView会更好。它更简单，旨在显示像学生一样的对象列表。
